International Telephone Input is a JavaScript plugin for entering and validating international telephone numbers. It takes a regular input field, adds a searchable country dropdown, auto-detects the user's country, displays a relevant placeholder number, formats the number as you type, and provides comprehensive validation methods. React and Vue components are also included.

## React and Vue Components
We now provide both React and Vue components alongside the regular JavaScript plugin. This readme is for the JavaScript plugin. View the [React Component readme](https://github.com/jackocnr/intl-tel-input/blob/master/react/README.md) or the [Vue Component readme](https://github.com/jackocnr/intl-tel-input/blob/master/vue/README.md).

## Demo and Examples
You can view [a live demo](https://intl-tel-input.com) and see some examples of how to use the various options. Alternatively, try it for yourself by downloading the project and opening demo.html in a browser.

## Mobile
By default, on mobile devices we show a fullscreen popup instead of the inline dropdown, to make better use of the limited screen space. This is similar to how a native `<select>` element works. You can control this behaviour with the `useFullscreenPopup` option. The popup can be closed by either selecting a country from the list or by tapping on the grey area at the sides. [See example](https://intl-tel-input.com/storybook/?path=/docs/intltelinput--usefullscreenpopup) (using the React component).

## Getting Started (Using a CDN)
1. Add the CSS
  ```html
  <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/intl-tel-input@24.6.0/build/css/intlTelInput.css">
  ```

2. Add the plugin script and initialise it on your input element
  ```html
  <script src="https://cdn.jsdelivr.net/npm/intl-tel-input@24.6.0/build/js/intlTelInput.min.js"></script>
  <script>
    const input = document.querySelector("#phone");
    window.intlTelInput(input, {
      loadUtilsOnInit: "https://cdn.jsdelivr.net/npm/intl-tel-input@24.6.0/build/js/utils.js",
    });
  </script>
  ```

## Getting Started (Using a bundler e.g. Webpack)
1. Install with npm: `npm install intl-tel-input --save` or yarn: `yarn add intl-tel-input`

2. Import the CSS: `import 'intl-tel-input/build/css/intlTelInput.css';`

3. Set the path to flags.webp and globe.webp in your CSS, by overriding the CSS variables
  ```css
  .iti {
    --iti-path-flags-1x: url('path/to/flags.webp');
    --iti-path-flags-2x: url('path/to/flags@2x.webp');
    --iti-path-globe-1x: url('path/to/globe.webp');
    --iti-path-globe-2x: url('path/to/globe@2x.webp');
  }
  ```

4. Import the JS and initialise the plugin on your input element
  ```js
  import intlTelInput from 'intl-tel-input';

  const input = document.querySelector("#phone");
  intlTelInput(input, {
      loadUtilsOnInit: () => import("intl-tel-input/utils")
  });
  ```

Most bundlers (such as Webpack, Vite, or Parcel) will see this and place the [utilities script](#utilities-script) in a separate bundle and load it asynchronously, only when needed. If this doesn’t work with your bundler or you want to load the utils module from some other location (such as a CDN) you can set the `loadUtilsOnInit` option to the URL to load from as a string. For example:

```js
import intlTelInput from 'intl-tel-input';

const input = document.querySelector("#phone");
intlTelInput(input, {
    loadUtilsOnInit: `https://cdn.jsdelivr.net/npm/intl-tel-input@${intlTelInput.version}/build/js/utils.js`;
});
```

## Getting Started (Not using a bundler)
1. Download the [latest release](https://github.com/jackocnr/intl-tel-input/releases/latest), or better yet install it with [npm](https://www.npmjs.com/package/intl-tel-input)

2. Add the stylesheet
  ```html
  <link rel="stylesheet" href="path/to/intlTelInput.css">
  ```

3. Set the path to flags.webp and globe.webp in your CSS, by overriding the CSS variables
  ```css
  .iti {
    --iti-path-flags-1x: url('path/to/flags.webp');
    --iti-path-flags-2x: url('path/to/flags@2x.webp');
    --iti-path-globe-1x: url('path/to/globe.webp');
    --iti-path-globe-2x: url('path/to/globe@2x.webp');
  }
  ```

4. Add the plugin script and initialise it on your input element
  ```html
  <script src="path/to/intlTelInput.js"></script>
  <script>
    const input = document.querySelector("#phone");
    window.intlTelInput(input, {
      loadUtilsOnInit: "path/to/utils.js"
    });
  </script>
  ```

## Recommended Usage
We highly recommend you [load the included utils.js](#loading-the-utilities-script), which enables formatting and validation etc. Then the plugin is built to always deal with numbers in the full international format (e.g. "+17024181234") and convert them accordingly - even when `nationalMode` or `separateDialCode` is enabled. We recommend you get, store, and set numbers exclusively in this format for simplicity - then you don't have to deal with handling the country code separately, as full international numbers include the country code information.

You can always get the full international number (including country code) using `getNumber`, then you only have to store that one string in your database (you don't have to store the country separately), and then the next time you initialise the plugin with that number in the input, it will automatically set the country and format it according to the options you specify (e.g. when using `nationalMode` it will automatically display the number in national format, removing the international dial code).

If you know the user's country, you can set it with `initialCountry` (e.g. `"us"` for the United States), and if you don't, we recommend setting `initialCountry` to `"auto"` (along with the `geoIpLookup` option) to determine the user's country based on their IP address - [see example](https://intl-tel-input.com/examples/lookup-country.html).

If you know the user's language, you can use the included translations to localise the country names (etc) - [see example](https://intl-tel-input.com/examples/localise-countries.html).

## Initialisation Options
When you initialise the plugin, the first argument is the input element, and the second is an object containing any initialisation options you want, which are detailed below. Note: any options that take country codes should be [ISO 3166-1 alpha-2](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2) codes.  

**allowDropdown**  
Type: `Boolean` Default: `true`  
Whether or not to allow the dropdown. If disabled, there is no dropdown arrow, and the selected country is not clickable. Also, if showFlags is enabled we display the selected flag on the right instead because it is just a marker of state. Note that if `separateDialCode` is enabled, `allowDropdown` is forced to `true` as the dropdown is required when the user types "+" in this case. Play with this option on [Storybook](https://intl-tel-input.com/storybook/?path=/docs/intltelinput--allowdropdown) (using the React component).

**autoPlaceholder**  
Type: `String` Default: `"polite"`  
Set the input's placeholder to an example number for the selected country, and update it if the country changes. You can specify the number type using the `placeholderNumberType` option. By default, it is set to `"polite"`, which means it will only set the placeholder if the input doesn't already have one. You can also set it to `"aggressive"`, which will replace any existing placeholder, or `"off"`. Requires the [utils script to be loaded](#loading-the-utilities-script).

**containerClass**  
Type: `String` Default: `""`  
Additional classes to add to the (injected) wrapper `<div>`.

**countryOrder**  
Type: `Array` Default: `null`  
Specify the ordering for the country list with an array of iso2 country codes. Any omitted countries will appear after those specified e.g. setting `countryOrder` to `["jp", "kr"]` will result in the list: Japan, South Korea, Afghanistan, Albania, Algeria etc...

**countrySearch**  
Type: `Boolean` Default: `true`  
Add a search input to the top of the dropdown, so users can filter the displayed countries.

**customPlaceholder**  
Type: `Function` Default: `null`  
Change the placeholder generated by autoPlaceholder. Must return a string.

```js
intlTelInput(input, {
  customPlaceholder: function(selectedCountryPlaceholder, selectedCountryData) {
    return "e.g. " + selectedCountryPlaceholder;
  },
});
```

**dropdownContainer**  
Type: `Node` Default: `null`  
Expects a node e.g. `document.body`. Instead of putting the country dropdown markup next to the input, append it to the specified node, and it will then be positioned next to the input using JavaScript (using `position: fixed`). This is useful when the input is inside a container with `overflow: hidden`. Note that the positioning is broken by scrolling, so the dropdown will automatically close on the `window` scroll event.

**excludeCountries**  
Type: `Array` Default: `[]`  
In the dropdown, display all countries except the ones you specify here. Play with this option on [Storybook](https://intl-tel-input.com/storybook/?path=/docs/intltelinput--excludecountries) (using the React component).

**fixDropdownWidth**  
Type: `Boolean` Default: `true`  
Fix the dropdown width to the input width (rather than being as wide as the longest country name). Play with this option on [Storybook](https://intl-tel-input.com/storybook/?path=/docs/intltelinput--fixdropdownwidth) (using the React component).

**formatAsYouType**  
Type: `Boolean` Default: `true`  
Automatically format the number as the user types. This feature will be disabled if the user types their own formatting characters. Requires the [utils script to be loaded](#loading-the-utilities-script).

**formatOnDisplay**  
Type: `Boolean` Default: `true`  
Format the input value (according to the `nationalMode` option) during initialisation, and on `setNumber`. Requires the [utils script to be loaded](#loading-the-utilities-script).

**geoIpLookup**  
Type: `Function` Default: `null`  
When setting `initialCountry` to `"auto"`, you must use this option to specify a custom function that calls an IP lookup service to get the user's location and then invokes the `success` callback with the relevant country code. Also note that when instantiating the plugin, a [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) object is returned under the `promise` instance property, so you can do something like `iti.promise.then(...)` to know when initialisation requests like this have completed.

Here is an example using the [ipapi](https://ipapi.co/api/?javascript#location-of-clients-ip) service:  
```js
intlTelInput(input, {
  initialCountry: "auto",
  geoIpLookup: function(success, failure) {
    fetch("https://ipapi.co/json")
      .then(function(res) { return res.json(); })
      .then(function(data) { success(data.country_code); })
      .catch(function() { failure(); });
  }
});
```
_Note that the `failure` callback must be called in the event of an error, hence the use of `catch()` in this example. Tip: store the result in a cookie to avoid repeat lookups!_

**hiddenInput**  
Type: `Function` Default: `null`  
Allows the creation of hidden input fields within a form to store the full international telephone number and the selected country code. It accepts a function that receives the name of the main telephone input as an argument. This function should return an object with `phone` and (optionally) `country` properties to specify the names of the hidden inputs for the phone number and country code, respectively. This is useful for non-Ajax form submissions to ensure the full international number and country code are captured, especially when `nationalMode` is enabled.

***Note**: This feature requires the input to be inside a `<form>` element, as it listens for the `submit` event on the closest form element. Also note that since this uses `getNumber` internally, firstly it requires the [utils script to be loaded](#loading-the-utilities-script), and secondly it expects a valid number and so will only work correctly if you have used `isValidNumber` to validate the number before allowing the form submit to go through.

```js
intlTelInput(input, {
  hiddenInput: function(telInputName) {
    return {
      phone: "phone_full",
      country: "country_code"
    };
  }
});
```

This will generate the following (hidden) elements, which will be automatically populated on submit:

```html
<input type="hidden" name="phone_full">
<input type="hidden" name="country_code">
```

**i18n**  
Type: `Object` Default: `{}`  
Allow localisation/customisation of the 200+ country names, as well as other user interface text (e.g. the placeholder text for the country search input). The easiest way to do this is to simply import one of the [provided translation modules](https://github.com/jackocnr/intl-tel-input/tree/master/build/js/i18n) and set `i18n` to that value (see option 1 below). You can also override one or more individual keys this way (see option 1 below). Alternatively, you can provide your own custom translations (see option 2 below). If providing your own, you will need to specify all the country names (which can be copied from the country-list project e.g. here are the [country names in French](https://github.com/umpirsky/country-list/blob/master/data/fr/country.json)), as well as a few UI strings (listed below). [See example](https://intl-tel-input.com/examples/localise-countries.html).

If we don't currently support a language you need, it's easy to [contribute this](https://github.com/jackocnr/intl-tel-input/blob/master/.github/CONTRIBUTING.md#adding-a-new-translation) yourself - you only need to provide a handful of UI translation strings, as we automatically pull in the country names from the country-list project.

Option 1: import one of the provided translation modules
```js
import { fr } from "intl-tel-input/i18n";

intlTelInput(input, {
  i18n: fr,
});

// or to override one or more keys, you could do something like this
intlTelInput(input, {
  i18n: {
    ...fr,
    searchPlaceholder: "Recherche de pays",
  },
});
```

Option 2: define your own custom translations
```js
intlTelInput(input, {
  i18n: {
    // Country names - see the full list in src/js/intl-tel-input/i18n/en/countries.ts
    af: "Afghanistan",
    al: "Albania",
    dz: "Algeria",
    as: "American Samoa",
    ad: "Andorra",
    ...
    // Aria label for the selected country element
    selectedCountryAriaLabel: "Selected country",
    // Screen reader text for when no country is selected
    noCountrySelected: "No country selected",
    // Aria label for the country list element
    countryListAriaLabel: "List of countries",
    // Placeholder for the search input in the dropdown
    searchPlaceholder: "Search",
    // Screen reader text for when the search produces no results
    zeroSearchResults: "No results found",
    // Screen reader text for when the search produces 1 result
    oneSearchResult: "1 result found",
    // Screen reader text for when the search produces multiple results
    multipleSearchResults: "${count} results found",
  }
});
```

**initialCountry**  
Type: `String` Default: `""`  
Set the initial country selection by specifying its country code e.g. `"us"` for the United States. (Be careful not to do this unless you are sure of the user's country, as it can lead to tricky issues if set incorrectly and the user auto-fills their national number and submits the form without checking - in certain cases, this can pass validation and you can end up storing a number with the wrong dial code). You can also set `initialCountry` to `"auto"`, which will look up the user's country based on their IP address (requires the `geoIpLookup` option - [see example](https://intl-tel-input.com/examples/lookup-country.html)). Note that however you use `initialCountry`, it will not update the country selection if the input already contains a number with an international dial code.

**loadUtilsOnInit** (see [v25 discussion](https://github.com/jackocnr/intl-tel-input/discussions/1842))  
Type: `String` or `() => Promise<module>` Default: `""` Example: `"/build/js/utils.js"`

This is one way to (lazy) load the included utils.js (to enable formatting/validation etc) - see [Loading The Utilities Script](#loading-the-utilities-script) for more options. You will need to host the [utils.js](https://github.com/jackocnr/intl-tel-input/blob/master/build/js/utils.js) file, and then set the `loadUtilsOnInit` option to that URL, or alternatively just point it to a CDN hosted version e.g. `"https://cdn.jsdelivr.net/npm/intl-tel-input@24.6.0/build/js/utils.js"`. The script is loaded via a [dynamic import](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/import) statement, which means the URL cannot be relative - it must be absolute.

Alternatively, this can be a function that returns a promise for the utils module. When using a bundler like Webpack, this can be used to tell the bundler that the utils script should be kept in a separate file from the rest of your code. For example: `{ loadUtilsOnInit: () => import("intl-tel-input/utils") }`.

The script is only fetched when you initialise the plugin, and additionally, only when the page has finished loading (on the window load event) to prevent blocking (the script is ~260KB). When instantiating the plugin, a [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) object is returned under the `promise` instance property, so you can do something like `iti.promise.then(callback)` to know when initialisation requests like this have finished. See [Utilities Script](#utilities-script) for more information.

**nationalMode**  
Type: `Boolean` Default: `true`  
Format numbers in the national format, rather than the international format. This applies to placeholder numbers, and when displaying users' existing numbers. Note that it's fine for users to type their numbers in national format - as long as they have selected the right country, you can use `getNumber` to extract a full international number - [see example](https://intl-tel-input.com/examples/national-mode.html). It is recommended to leave this option enabled, to encourage users to enter their numbers in national format as this is usually more familiar to them and so it creates a better user experience.

**onlyCountries**  
Type: `Array` Default: `[]`  
In the dropdown, display only the countries you specify - [see example](https://intl-tel-input.com/examples/only-countries.html).

**placeholderNumberType**  
Type: `String` Default: `"MOBILE"`  
Specify [one of the keys](https://github.com/jackocnr/intl-tel-input/blob/master/src/js/utils.js#L162) from the enum `intlTelInput.utils.numberType` (e.g. `"FIXED_LINE"`) to set the number type to use for the placeholder. Play with this option on [Storybook](https://intl-tel-input.com/storybook/?path=/docs/intltelinput--placeholdernumbertype) (using the React component).

**showFlags**  
Type: `Boolean` Default: `true`  
Set this to false to hide the flags e.g. for political reasons. Instead, it will show a generic globe icon. Play with this option on [Storybook](https://intl-tel-input.com/storybook/?path=/docs/intltelinput--showflags) (using the React component).

**separateDialCode**  
Type: `Boolean` Default: `false`  
Display the selected country's international dial code next to the input, so it looks like it's part of the typed number. Since the user cannot edit the displayed dial code, they may try to type a new one - in this case, to avoid having two dial codes next to each other, we automatically open the country dropdown and put the new dial code in the search input instead. So if they type +54, then Argentina will be highlighted in the dropdown and they can simply press Enter to select it, updating the displayed dial code (this feature requires `allowDropdown` and `countrySearch` to be enabled). Play with this option on [Storybook](https://intl-tel-input.com/storybook/?path=/docs/intltelinput--separatedialcode) (using the React component).

<img src="https://raw.github.com/jackocnr/intl-tel-input/master/screenshots/separate-dial-code4.png" width="267px" height="51px" alt="Separate Dial Code">

**strictMode**  
Type: `Boolean` Default: `false`  
As the user types in the input, ignore any irrelevant characters. The user can only enter numeric characters and an optional plus at the beginning. Cap the length at the maximum valid number length (this respects `validationNumberType`). Requires the [utils script to be loaded](#loading-the-utilities-script). [See example](https://intl-tel-input.com/examples/strict-mode.html).

**useFullscreenPopup**  
Type: `Boolean` Default: `true on mobile devices, false otherwise`  
Control when the country list appears as a fullscreen popup vs an inline dropdown. By default, it will appear as a fullscreen popup on mobile devices (based on user-agent and screen width), to make better use of the limited space (similar to how a native `<select>` works), and as an inline dropdown on larger devices/screens. Play with this option on [Storybook](https://intl-tel-input.com/storybook/?path=/docs/intltelinput--usefullscreenpopup) (using the React component).

**utilsScript** ⚠️ DEPRECATED  
Type: `String` or `() => Promise<module>` Default: `""` Example: `"/build/js/utils.js"`

This option is deprecated and has been renamed to `loadUtilsOnInit`. Please see the deatails for that option and use it instead.

**validationNumberType**  
Type: `String` Default: `"MOBILE"`  
Specify [one of the keys](https://github.com/jackocnr/intl-tel-input/blob/master/src/js/utils.js#L162) from the enum `intlTelInput.utils.numberType` (e.g. `"FIXED_LINE"`) to set the number type to enforce during validation with `isValidNumber`, as well as the number length to enforce with `strictMode`. Set it to `null` to not enforce any particular type. 

## Instance Methods
In these examples, `iti` refers to the plugin instance which gets returned when you initialise the plugin e.g.
```js
const iti = intlTelInput(input);
```

**destroy**  
Remove the plugin from the input, and unbind any event listeners.  
```js
iti.destroy();
```

**getExtension**  
Get the extension from the current number. Requires the [utils script to be loaded](#loading-the-utilities-script).
```js
const extension = iti.getExtension();
```
Returns a string e.g. if the input value was `"(702) 555-5555 ext. 1234"`, this would return `"1234"`

**getNumber**  
Get the current number in the given format (defaults to [E.164 standard](https://en.wikipedia.org/wiki/E.164)). The different formats are available in the enum `intlTelInput.utils.numberFormat` - which you can see [here](https://github.com/jackocnr/intl-tel-input/blob/master/src/js/utils.js#L153). Requires the [utils script to be loaded](#loading-the-utilities-script). _Note that even if `nationalMode` is enabled, this can still return a full international number. Also note that this method expects a valid number, and so should only be used after validation._  
```js
const number = iti.getNumber();
// or
const number = iti.getNumber(intlTelInput.utils.numberFormat.E164);
```
Returns a string e.g. `"+17024181234"`

**getNumberType**  
Get the type (fixed-line/mobile/toll-free etc) of the current number. Requires the [utils script to be loaded](#loading-the-utilities-script).  
```js
const numberType = iti.getNumberType();
```
Returns an integer, which you can match against the [various options](https://github.com/jackocnr/intl-tel-input/blob/master/src/js/utils.js#L162) in the enum `intlTelInput.utils.numberType` e.g.  
```js
if (numberType === intlTelInput.utils.numberType.MOBILE) {
    // is a mobile number
}
```
_Note that in the US there's no way to differentiate between fixed-line and mobile numbers, so instead it will return `FIXED_LINE_OR_MOBILE`._

**getSelectedCountryData**  
Get the country data for the currently selected country.  
```js
const countryData = iti.getSelectedCountryData();
```
Returns something like this:
```js
{
  name: "Afghanistan",
  iso2: "af",
  dialCode: "93"
}
```

**getValidationError**  
Get more information about a validation error. Requires the [utils script to be loaded](#loading-the-utilities-script).  
```js
const error = iti.getValidationError();
```
Returns an integer, which you can match against the [various options](https://github.com/jackocnr/intl-tel-input/blob/master/src/js/utils.js#L178) in the enum `intlTelInput.utils.validationError` e.g.  
```js
if (error === intlTelInput.utils.validationError.TOO_SHORT) {
    // the number is too short
}
```

**isValidNumber**  
Check if the current number is valid based on its length - [see example](https://intl-tel-input.com/examples/validation-practical.html), which should be sufficient for most use cases. See `isValidNumberPrecise` for more precise validation, but the advantage of `isValidNumber` is that it is much more future-proof as while countries around the world regularly update their number rules, they very rarely change their number lengths. If this method returns `false`, you can use `getValidationError` to get more information. Respects the `validationNumberType` option (which is set to "MOBILE" by default). Requires the [utils script to be loaded](#loading-the-utilities-script).
```js
const isValid = iti.isValidNumber();
```
Returns: `true`/`false`

**isValidNumberPrecise** ⚠️ DEPRECATED - see [discussion](https://github.com/jackocnr/intl-tel-input/discussions/1840)  
Check if the current number is valid using precise matching rules for each country/area code etc - [see example](https://intl-tel-input.com/examples/validation.html). Note that these rules change each month for various countries around the world, so you need to be careful to keep the plugin up-to-date else you will start rejecting valid numbers. For a simpler and more future-proof form of validation, see `isValidNumber` above. If validation fails, you can use `getValidationError` to get more information. Requires the [utils script to be loaded](#loading-the-utilities-script).  
```js
const isValid = iti.isValidNumberPrecise();
```
Returns: `true`/`false`

**setCountry**  
Change the selected country. It should be rare, if ever, that you need to do this, as the selected country gets updated automatically when calling `setNumber` and passing a number including an international dial code, which is the recommended usage. Note you can omit the country code argument to set the country to the default empty (globe) state.
```js
iti.setCountry("gb");
```

**setNumber**  
Insert a number, and update the selected country accordingly. _Note that if `formatOnDisplay` is enabled, this will attempt to format the number to either national or international format according to the `nationalMode` option._  
```js
iti.setNumber("+447733123456");
```

**setPlaceholderNumberType**  
Change the placeholderNumberType option.
```js
iti.setPlaceholderNumberType("FIXED_LINE");
```

**setDisabled**  
Updates the disabled attribute of both the telephone input and the selected country button. Accepts a boolean value. _Note: we recommend using this instead of updating the disabled attribute of the input directly._
```js
iti.setDisabled(true);
```

## Static Methods

**getCountryData**  
Retrieve the plugin's country data - either to re-use elsewhere e.g. to generate your own country dropdown - [see example](https://intl-tel-input.com/examples/country-sync.html), or alternatively, you could use it to modify the country data. Note that any modifications must be done before initialising the plugin.  
```js
const countryData = intlTelInput.getCountryData();
```
Returns an array of country objects:
```js
[{
  name: "Afghanistan",
  iso2: "af",
  dialCode: "93"
}, ...]
```

**getInstance**  
After initialising the plugin, you can always access the instance again using this method, by just passing in the relevant input element.
```js
const input = document.querySelector('#phone');
const iti = intlTelInput.getInstance(input);
iti.isValidNumber(); // etc
```

**loadUtils** (see [v25 discussion](https://github.com/jackocnr/intl-tel-input/discussions/1842))  
An alternative to the `loadUtilsOnInit` option, this method lets you manually load the utils.js script on demand, to enable formatting/validation etc. See [Loading The Utilities Script](#loading-the-utilities-script) for more information. This method should only be called once per page. A [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) object is returned so you can use `loadUtils().then(callback)` to know when it's finished.
```js
// Load from a URL:
intlTelInput.loadUtils("/build/js/utils.js");

// Or manage load via some other method with a function:
intlTelInput.loadUtils(async () => {
    // Your own loading logic here. Return a JavaScript "module" object with
    // the utils as the default export.
    return { default: { /* a copy of the utils module */ } }
});
```

## Events
You can listen for the following events triggered on the input element.

**countrychange**  
This is triggered when the selected country is updated e.g. if the user selects a country from the dropdown, or they type a different dial code into the input, or you call `setCountry` etc.
```js
input.addEventListener("countrychange", function() {
  // do something with iti.getSelectedCountryData()
});
```
See an example here: [Country sync](https://intl-tel-input.com/examples/country-sync.html)  

**open:countrydropdown**  
This is triggered when the user opens the dropdown.  

**close:countrydropdown**  
This is triggered when the user closes the dropdown.  

## Theming / Dark Mode
There are lots of CSS variables available for theming. See [intlTelInput.scss](https://github.com/jackocnr/intl-tel-input/blob/master/src/css/intlTelInput.scss) for the full list.

As for the empty state (globe icon), the default version is dark grey, and we also provide a "light" version, that should work better with a dark theme. Alternatively, it's easy to [re-generate the globe icon](https://free-icon-rainbow.com/international-call-free-icon) in whatever colour you need for your theme. We recommend you download it in the highest resolution possible, and then scale the image down to the required sizes (20px wide for the default version and 40px wide for the @2x version).

Dark mode example (with screenshot below):
```css
@media (prefers-color-scheme: dark) {
  .iti {
    --iti-border-color: #5b5b5b;
    --iti-dialcode-color: #999999;
    --iti-dropdown-bg: #0d1117;
    --iti-arrow-color: #aaaaaa;
    --iti-hover-color: #30363d;
    --iti-path-globe-1x: url("path/to/globe_light.webp");
    --iti-path-globe-2x: url("path/to/globe_light@2x.webp");
  }
}
```

NOTE: this assumes you already have your own dark mode styling in place for general body/input styling e.g. something like this:

```css
@media (prefers-color-scheme: dark) {
  body, input {
    color: white;
    background-color: #0d1117;
  }
  input {
    border-color: #5b5b5b;
  }
  input::placeholder {
    color: #8d96a0;
  }
}
```

## Utilities Script
The utilities script ([build/js/utils.js](build/js/utils.js)) is a custom build of Google's [libphonenumber](https://github.com/googlei18n/libphonenumber) which enables the following features:

* Formatting upon initialisation, as well as with `getNumber` and `setNumber`
* Validation with `isValidNumber`, `getNumberType` and `getValidationError` methods
* Placeholder set to an example number for the selected country - even specify the type of number (e.g. mobile) using the `placeholderNumberType` option
* Extract the standardised (E.164) international number with `getNumber` even when using the `nationalMode` option

International number formatting/validation is hard (it varies by country/district, and we currently support ~230 countries). The only comprehensive solution we have found is libphonenumber, from which we have precompiled the relevant parts into a single JavaScript file, included in the build directory. Unfortunately, even after modification, it is still ~260KB. See the section below on the best way to load it.

To recompile the utils script yourself (e.g. to update the version of libphonenumber it is built from), see the [contributing guide](https://github.com/jackocnr/intl-tel-input/blob/master/.github/CONTRIBUTING.md#updating-to-a-new-version-of-libphonenumber).

## Loading The Utilities Script 
See [v25 discussion](https://github.com/jackocnr/intl-tel-input/discussions/1842).  

The utils script provides lots of great functionality (see above section), but comes at the cost of increased filesize (~260KB). There are two main ways to load the utils script, depending on whether you're concerned about filesize or not.

**Option 1: intlTelInputWithUtils**  
If you're not concerned about filesize (e.g. you're lazy loading this script), the easiest thing to do is to just use the full bundle (`/build/js/intlTelInputWithUtils.js`), which comes with the utils script included. This script can be used exactly like the main intlTelInput.js - so it can either be loaded directly onto the page (which defines `window.intlTelInput` like usual), or it can be imported like so: `import intlTelInput from "intl-tel-input/intlTelInputWithUtils"`.

**Option 2: loadUtilsOnInit**  
If you *are* concerned about filesize, you can lazy load the utils script when the plugin initialises, using the `loadUtilsOnInit` initialisation option. You will need to host the [utils.js](https://github.com/jackocnr/intl-tel-input/blob/master/build/js/utils.js) file, and then set the `loadUtilsOnInit` option to that URL, or just point it to a CDN hosted version e.g. `"https://cdn.jsdelivr.net/npm/intl-tel-input@24.6.0/build/js/utils.js"`.

Alternatively, you can set the `loadUtilsOnInit` option to a function that returns a promise for the utils script as a JS module object. If you use a bundler like Webpack, Vite, or Parcel to build your app, you can use it like this automatically separate the utils into a different bundle:

```js
intlTelInput(htmlInputElement, {
  loadUtilsOnInit: () => import("intl-tel-input/utils)
});
```

If you want more control over when this file is lazy loaded, you can manually invoke the `loadUtils` static method, instead of using `loadUtilsOnInit`.

## Troubleshooting

**Full-width input**  
If you want your input to be full-width, you need to set the container to be the same i.e.

```css
.iti { width: 100%; }
```

**dropdownContainer: dropdown not closing on scroll**  
If you have a scrolling container other than `window` which is causing problems by not closing the dropdown on scroll, simply listen for the scroll event on that element, and trigger a scroll event on `window`, which in turn will close the dropdown e.g.

```js
scrollingElement.addEventListener("scroll", function() {
  const e = document.createEvent('Event');
  e.initEvent("scroll", true, true);
  window.dispatchEvent(e);
});
```

**Input margin**  
For the sake of alignment, the default CSS forces the input's vertical margin to `0px`. If you want vertical margin, you should add it to the container (with class `iti`).

**Displaying error messages**  
If your error handling code inserts an error message before the `<input>` it will break the layout. Instead, you must insert it before the container (with class `iti`).

**Dropdown position**  
The dropdown should automatically appear above/below the input depending on the available space. For this to work properly, you must only initialise the plugin after the `<input>` has been added to the DOM.

**Placeholders**  
To get the automatic country-specific placeholders, simply omit the placeholder attribute on the `<input>`, or set `autoPlaceholder` to `"aggressive"` to override any existing placeholder,

**Bootstrap input groups**  
A couple of CSS fixes are required to get the plugin to play nice with Bootstrap [input groups](https://getbootstrap.com/docs/3.3/components/#input-groups). You can see a Codepen [here](https://codepen.io/jackocnr/pen/EyPXed).  
_Note: there is currently [a bug](https://bugs.webkit.org/show_bug.cgi?id=141822) in Mobile Safari which causes a crash when you click the dropdown arrow (a CSS triangle) inside an input group. The simplest workaround is to remove the CSS triangle with this line:_

```css
.iti__arrow { border: none; }
```
