## Features

- Extends our [input](../input/overview.md)
- Shows a mobile telephone keypad on mobile (by having a native `<input inputmode="tel">` inside)
- Can be configured with a list of allowed region codes
- Will be preconfigured with region derived from locale
- Has the [e164 standard format](https://en.wikipedia.org/wiki/E.164) as modelValue
- Uses [awesome-phonenumber](https://www.npmjs.com/package/awesome-phonenumber) (a performant, concise version of [google-lib-phonenumber](https://www.npmjs.com/package/google-libphonenumber)):
  - Formats phone numbers, based on region code
  - Validates phone numbers, based on region code
- Lazy loads awesome-phonenumber, so that the first paint of this component will be brought to your screen as quick as possible
