# react-phone-number-input [![npm version](https://img.shields.io/npm/v/react-phone-number-input.svg?style=flat-square)](https://www.npmjs.com/package/react-phone-number-input) [![npm downloads](https://img.shields.io/npm/dm/react-phone-number-input.svg?style=flat-square)](https://www.npmjs.com/package/react-phone-number-input) International phone number `` for React. [

](http://catamphetamine.gitlab.io/react-phone-number-input/) [See Demo](http://catamphetamine.gitlab.io/react-phone-number-input/) ## Install ``` npm install react-phone-number-input --save ``` If you're not using a bundler then use a [standalone version from a CDN](https://gitlab.com/catamphetamine/react-phone-number-input/#cdn). The component uses [`libphonenumber-js`](https://www.npmjs.com/package/libphonenumber-js) for phone number parsing and formatting. ## Use The component comes in two variants: "with country select" and "without country select". ## With country select "With country select" component requires two properties: `value` and `onChange(value)`. [See the list of all available `props`](http://catamphetamine.gitlab.io/react-phone-number-input/docs/index.html#phoneinputwithcountry). ```js import 'react-phone-number-input/style.css' import PhoneInput from 'react-phone-number-input' function Example() { // `value` will be the parsed phone number in E.164 format. // Example: "+12133734253". const [value, setValue] = useState() return ( ) } ``` The `value` argument of `onChange(value)` function will be the parsed phone number in [E.164](https://en.wikipedia.org/wiki/E.164) format. For example, if a user chooses "United States" and enters `(213) 373-4253` in the input field then `onChange(value)` will be called with `value` being `"+12133734253"`. Any ["falsy"](https://developer.mozilla.org/en-US/docs/Glossary/Falsy) `value` like `undefined`, `null` or an empty string `""` is treated like "empty". In case of the `onChange()` function's `value` argument though it's always `undefined` for an "empty" `value`, i.e. when the user erases the input value, `onChange()` is called with `undefined` as an argument. Perhaps `null` would've been better, but historically it has been `undefined`. All unknown properties will be passed through to the phone number `` component. To set a default country, pass a `defaultCountry` property (must be a supported [country code](#country-code)). Example: ``. To get the currently selected country, pass an `onCountryChange(country)` property. To get the country of a complete phone number, use [`parsePhoneNumber(value)`](#parsephonenumberinput-string-phonenumber): `parsePhoneNumber(value) && parsePhoneNumber(value).country`. To format `value` back to a human-readable phone number, use [`formatPhoneNumber(value)`](#formatphonenumbervalue-string-string) or [`formatPhoneNumberIntl(value)`](#formatphonenumberintlvalue-string-string). #### CSS "With country select" component comes with a [`style.css`](https://gitlab.com/catamphetamine/react-phone-number-input/blob/master/style.css) stylesheet. All CSS class names start with `.PhoneInput`. Additional "modifier" CSS classes: `.PhoneInput--focus` for `:focus`, `.PhoneInput--disabled` for `:disabled`, `.PhoneInput--readOnly` for `[readonly]`. The stylesheet uses [native CSS variables](https://medium.freecodecamp.org/learn-css-variables-in-5-minutes-80cf63b4025d) for convenience. Native CSS variables work in all modern browsers, but older ones like Internet Explorer [wont't support them](https://caniuse.com/#search=var). For compatibility with such older browsers one can use a CSS transformer like [PostCSS](http://postcss.org/) with a "CSS custom properties" plugin like [`postcss-custom-properties`](https://github.com/postcss/postcss-custom-properties). Some of the CSS variables: * `--PhoneInputCountryFlag-height` — Flag icon height. * `--PhoneInputCountryFlag-borderColor` — Flag icon outline color. * `--PhoneInputCountrySelectArrow-color` — Country select arrow color. * `--PhoneInputCountrySelectArrow-opacity` — Country select arrow opacity (when not `:focus`ed). * `--PhoneInput-color--focus` — Flag icon `:focus` outline color, and also country select arrow `:focus` color. * … ##### When using Webpack When using Webpack, include the stylesheet on a page via `import`: ```js import 'react-phone-number-input/style.css' ``` For supporting old browsers like Internet Explorer, one could use [`postcss-loader`](https://github.com/postcss/postcss-loader) with a [CSS autoprefixer](https://github.com/postcss/autoprefixer) and [`postcss-custom-properties` transpiler](https://github.com/postcss/postcss-custom-properties). ##### When not using Webpack Get `style.css` file from this package, optionally process it with a [CSS autoprefixer](https://github.com/postcss/autoprefixer) and [`postcss-custom-properties` transpiler](https://github.com/postcss/postcss-custom-properties) for supporting old web browsers, and then include the CSS file on a page. ```html ``` Or include the `style.css` file directly from a [CDN](#cdn) if you don't have to support Internet Explorer. ## Without country select "Without country select" component is just a phone number ``. ```js import PhoneInput from 'react-phone-number-input/input' function Example() { // `value` will be the parsed phone number in E.164 format. // Example: "+12133734253". const [value, setValue] = useState() // If `country` property is not passed // then "International" format is used. // Otherwise, "National" format is used. return ( ) } ``` Doesn't require any CSS. Receives properties: * `country: string?` — If `country` is specified then the input value will be formatted (and parsed) as a phone number that belongs to the `country`. `country` must be a supported [country code](#country-code). Example: `country="US"`. * `international: boolean?` — Controls whether the input value should be formatted (and parsed) as an "international" phone number as opposed to "national". When this property is omitted, its default value will be determined based on the values of other properties such as `country` or `defaultCountry`: * When `country` is specified: * When `international` property is not specified then the default value for `international` property is `false` meaning that the phone number can only be input in "national" format for that `country`. * Example: if `country` is `"US"` and `international` property is not passed then the phone number can only be input in the "national" format for `US` (e.g. `"(213) 373-4253"`). * When `international` property is explicitly set to `true` then the phone number can only be input in "international" format for that `country`. * By default, the "country calling code" part (e.g. `"+1"` when `country` is `"US"`) is not included in the input field. * Example: if `country` is `"US"` and `international` property is `true` then the phone number can only be input in the "international" format for `US` (e.g. `"213 373 4253"`), that is without the "country calling code" part (`"+1"`). * This could be used for implementing phone number input components that show "country calling code" part separately before the input field. * If `withCountryCallingCode` property is explicitly set to `true` then the "country calling code" part (e.g. `"+1"` when `country` is `"US"`) is included in the input field (but still isn't editable). * Example: if `country` is `"US"` and `international` property is `true` and `withCountryCallingCode` property is `true` then the phone number can only be input in the "international" format for `US` (e.g. `"+1 213 373 4253"`), including the "country calling code" part `"+1"` (which isn't editable though). * When `defaultCountry` is specified then the phone number could be input either in "national" or "international" format for that `defaultCountry`, so `international` property shouldn't be used in this case. * When no `defaultCountry` or `country` are specified, the phone number can only be input in "international" format (for any country), so `international` property shouldn't be passed and is `true` by default. * `withCountryCallingCode: boolean?` — If `country` is specified and `international` property is `true` then the phone number can only be input in "international" format for that `country`. By default, the "country calling code" part (example: `+1` when `country` is `US`) is not included in the input field. To change that, pass `withCountryCallingCode` property, and it will include the "country calling code" part in the input field. See the demo for an example. * `defaultCountry: string?` — If `defaultCountry` is specified then the phone number can be input both in "international" format and "national" format. A phone number that's being input in "national" format will be parsed as a phone number belonging to the `defaultCountry`. Must be a supported [country code](#country-code). Example: `defaultCountry="US"`. * `useNationalFormatForDefaultCountryValue: boolean?` — When `defaultCountry` is defined and the initial `value` corresponds to `defaultCountry`, then the `value` will be formatted as a national phone number by default. To format the initial `value` of `defaultCountry` as an international number instead set `useNationalFormatForDefaultCountryValue` property to `false`. * `value: string?` — Phone number `value`. Examples: `undefined`, `"+12133734253"`. * `onChange(value: string?)` — Updates the `value` (to `undefined` in case it's empty). * `inputComponent: component?` — Custom input component. * By default, it's a generic DOM `` component. * Any custom input component implementation must use `React.forwardRef()` to "forward" `ref` to the underlying "core" `` component. * Receives properties: * `value: string` * `onChange(event: Event)` * Any other properties that were passed to `` and aren't specifically handled by this library. For example, `type="tel"`, `autoComplete="tel"`, etc. * `smartCaret: boolean?` — When the user attempts to insert a digit somewhere in the middle of a phone number, the caret position is moved right before the next available digit skipping any punctuation in between. This is called "smart" caret positioning. Another case would be the phone number format changing as a result of the user inserting the digit somewhere in the middle, which would require re-positioning the caret because all digit positions have changed. This "smart" caret positioning feature can be turned off by passing `smartCaret={false}` property: use it in case of any possible issues with caret position during phone number input. See the [demo](http://catamphetamine.gitlab.io/react-phone-number-input/) for the examples. For those who want to pass custom `metadata` there's `react-phone-number-input/input-core` sub-package. This library also exports `getCountries()` and `getCountryCallingCode(country)` functions that a developer could use to construct their own custom country select. Such custom country `` described above.

Creating a custom country <select/>

#### ```js import PropTypes from 'prop-types' import { getCountries, getCountryCallingCode } from 'react-phone-number-input' const CountrySelect = ({ value, onChange, labels, ...rest }) => ( ) CountrySelect.propTypes = { value: PropTypes.string, onChange: PropTypes.func.isRequired, labels: PropTypes.objectOf(PropTypes.string).isRequired } ``` Use: ```js import PhoneInput from 'react-phone-number-input/input' import en from 'react-phone-number-input/locale/en' import CountrySelect from './CountrySelect' function Example() { const [country, setCountry] = useState('US') const [value, setValue] = useState() return (

) } ```

## React Native This library also includes a React Native version of a "without country select" component. Post bug reports and suggestions in the [feedback thread](https://github.com/catamphetamine/react-phone-number-input/issues/296). ```js import React, { useState } from 'react' import PhoneInput from 'react-phone-number-input/react-native-input' function Example() { const [value, setValue] = useState() return ( ) } ``` Accepts the same properties as the web version of "without country select" component, with the following differences: * `smartCaret: boolean?` property is not accepted because "smart caret" positioning feature is not implemented in the React Native component. * `inputComponent: component?` — A custom input field component can be passed. In that case, it must do `React.forwardRef()` to the actual input field. Receives properties: `value: string`, `onChangeText(value: string)`, and all the "rest" of the properties that're not handled by this library, like `keyboardType="phone-pad"`, `autoCompleteType="tel"`, etc. Is a generic `` by default. ## Utility This package exports several utility functions. ### `formatPhoneNumber(value: string): string` Formats `value` as a "local" phone number. ```js import { formatPhoneNumber } from 'react-phone-number-input' formatPhoneNumber('+12133734253') === '(213) 373-4253' ``` ### `formatPhoneNumberIntl(value: string): string` Formats `value` as an "international" phone number. ```js import { formatPhoneNumberIntl } from 'react-phone-number-input' formatPhoneNumberIntl('+12133734253') === '+1 213 373 4253' ``` ### `isPossiblePhoneNumber(value: string): boolean` Checks if a phone number `value` is a "possible" phone number. A phone number is "possible" when it has valid length. The actual phone number digits aren't validated. ```js import { isPossiblePhoneNumber } from 'react-phone-number-input' isPossiblePhoneNumber('+12223333333') === true ``` ### `isValidPhoneNumber(value: string): boolean` Checks if a phone number `value` is a "valid" phone number. A phone number is "valid" when it has valid length, and the actual phone number digits match the regular expressions for that country. ```js import { isValidPhoneNumber } from 'react-phone-number-input' isValidPhoneNumber('+12223333333') === false isValidPhoneNumber('+12133734253') === true ``` By default the component uses [`min` "metadata"](#min-vs-max-vs-mobile) which results in less strict validation compared to [`max`](#min-vs-max-vs-mobile) or [`mobile`](#min-vs-max-vs-mobile). I personally don't use `isValidPhoneNumber()` for phone number validation in my projects. The rationale is that telephone numbering plans can and sometimes do change, meaning that `isValidPhoneNumber()`function may one day become outdated on a website that isn't actively maintained anymore. Imagine a "promo-site" or a "personal website" being deployed once and then running for years without any maintenance, where a client may be unable to submit a simple "Contact Us" form just because this newly allocated pool of mobile phone numbers wasn't present in that old version of `libphonenumber-js` bundled in it. Whenever there's a "business requirement" to validate a phone number that's being input by a user, I prefer using `isPossiblePhoneNumber()` instead of `isValidPhoneNumber()`, so that it just validates the phone number length, and doesn't validate the actual phone number digits. But it doesn't mean that you shouldn't use `isValidPhoneNumber()` — maybe in your case it would make sense. ### `parsePhoneNumber(input: string): PhoneNumber?` Parses a [`PhoneNumber`](https://gitlab.com/catamphetamine/libphonenumber-js#phonenumber) object from a `string`. This is simply an alias for [`parsePhoneNumber()`](https://gitlab.com/catamphetamine/libphonenumber-js#parsephonenumberstring-options-or-defaultcountry-phonenumber) from [`libphonenumber-js`](https://gitlab.com/catamphetamine/libphonenumber-js). Can be used to get `country` from `value`. ```js import { parsePhoneNumber } from 'react-phone-number-input' const phoneNumber = parsePhoneNumber('+12133734253') if (phoneNumber) { phoneNumber.country === 'US' } ``` ### `getCountryCallingCode(country: string): string` Returns the ["country calling code"](https://gitlab.com/catamphetamine/libphonenumber-js#country-calling-code) of a `country`. The `country` argument must be a supported [country code](#country-code). This is simply an alias for [`getCountryCallingCode()`](https://gitlab.com/catamphetamine/libphonenumber-js#getcountrycallingcodecountry) from [`libphonenumber-js`](https://gitlab.com/catamphetamine/libphonenumber-js). ```js import { getCountryCallingCode } from 'react-phone-number-input' getCountryCallingCode('US') === '1' ``` ### `isSupportedCountry(country: string): boolean` Checks if a [country](#country-code) is supported by this library. This is simply an alias for [`isSupportedCountry()`](https://gitlab.com/catamphetamine/libphonenumber-js#issupportedcountrycountry-string-boolean) from [`libphonenumber-js`](https://gitlab.com/catamphetamine/libphonenumber-js). ```js import { isSupportedCountry } from 'react-phone-number-input' isSupportedCountry('US') === true ``` ## Flags URL By default, all flags are linked from [`country-flag-icons`](https://gitlab.com/catamphetamine/country-flag-icons)'s [GitHub pages](https://purecatamphetamine.github.io/country-flag-icons/3x2) website as `

`s. Any other flag icons could be used instead by passing a custom [`flagUrl`](http://catamphetamine.gitlab.io/react-phone-number-input/docs#phoneinputwithcountry) property (which is `"https://purecatamphetamine.github.io/country-flag-icons/3x2/{XX}.svg"` by default) and specifying their aspect ratio via [`--PhoneInputCountryFlag-aspectRatio`](https://gitlab.com/catamphetamine/react-phone-number-input/blob/master/style.css) CSS variable (which is `1.5` by default, meaning "3x2" aspect ratio). For example, using [`flagpack`](https://github.com/jackiboy/flagpack) "4x3" flag icons would be as simple as: ```css :root { --PhoneInputCountryFlag-aspectRatio: 1.333; } ``` ```js ``` ## Including all flags Linking flag icons as external ``s is only done to reduce the overall bundle size, because including all country flags in the code as inline ``s would increase the bundle size by 44 kB (after gzip). If bundle size is not an issue (for example, for a standalone non-web application, or an "intranet" application), then all country flags can be included directly in the code by passing the [`flags`](http://catamphetamine.gitlab.io/react-phone-number-input/docs#phoneinputwithcountry) property: ```js import PhoneInput from 'react-phone-number-input' import flags from 'react-phone-number-input/flags' ``` ## Localization Language translations can be applied using the `labels` property. This component comes pre-packaged with several [translations](https://gitlab.com/catamphetamine/react-phone-number-input/tree/master/locale). Submit pull requests for adding new language translations.

Where to get country names for any language.

#### Country names can be copy-pasted from [`github.com/umpirsky/country-list`](https://github.com/umpirsky/country-list/blob/master/data/). ```js JSON.stringify( Object.keys(countries).sort() .reduce((all, country) => ({ ...all, [country]: countries[country] }), {}), null, '\t' ) ```` Also note that a country names list generated from `umpirsky/country-list` won't include Ascension Island (`AC`) and Tristan da Cunha (`TA`) — they will need to be added manually.

#### The `labels` format is: ```js { // Can be used as a label for country input. // Country `` component. * [`countrySelectComponent`](#countryselectcomponent) — Custom country ``. Renders an "arrow" "dropdown" icon. Doesn't receive any properties. All those customization properties have their default values which are, therefore, always included in the application bundle, regardless of whether those default property values get overridden by any custom ones. Those who'd like to exclude the default values just for `metadata` and `labels` properties could `import` the component from `react-phone-number-input/core` subpackage rather than from `react-phone-number-input` package. #### `countrySelectComponent` React component for the country select. See [CountrySelect.js](https://gitlab.com/catamphetamine/react-phone-number-input/blob/master/source/CountrySelect.js) for an example. Receives properties: * `name: string?` — HTML `name` attribute. * `value: string?` — The currently selected country code (`undefined` in case of "International"). * `onChange(value: string?)` — Updates the `value` (to `undefined` in case of "International"). * `onFocus()` — Is used to toggle the `--focus` CSS class. * `onBlur()` — Is used to toggle the `--focus` CSS class. * `options: object[]` — The list of all selectable countries (including "International") each being an object of shape `{ value: string?, label: string }`. * `iconComponent: PropTypes.elementType` — React component that renders a country icon: ``. If `country` is `undefined` then it renders an "International" icon. * `disabled: boolean?` — HTML `disabled` attribute. * `readOnly: boolean?` — HTML `readonly` attribute. * `tabIndex: (number|string)?` — HTML `tabIndex` attribute. * `className: string` — CSS class name. #### `inputComponent` A React component for the phone number input field. Is `"input"` by default, meaning that it renders a standard DOM ``. Any custom input component implementation must use `React.forwardRef()` to "forward" `ref` to the underlying "core" `` component. Receives properties: * `value: string` — The formatted `value`. * `onChange(event: Event)` — Updates the formatted `value` from `event.target.value`. * `onFocus()` — Is used to toggle the `--focus` CSS class. * `onBlur(event: Event)` — Is used to toggle the `--focus` CSS class. * Other properties like `type="tel"` or `autoComplete="tel"` that should be passed through to the DOM ``. #### `flagComponent` Renders a country flag icon. Receives properties: * `country: string` — A two-letter ISO country code. Example: `"RU"`. * `countryName: string` — Country name. Example: `"Russia"`. * `flags?: object` — An object that contains a flag icon component for each country. Same as the [`flags`](https://catamphetamine.gitlab.io/react-phone-number-input/docs/#phoneinputwithcountry) property of the `react-phone-number-input` component. * `flagUrl?: string` — A template for a country flag icon image URL. Same as the [`flagUrl`](https://catamphetamine.gitlab.io/react-phone-number-input/docs/#phoneinputwithcountry) property of the `react-phone-number-input` component. * `className: string` — CSS class name. #### `internationalIcon` Renders an "International" icon. For example, the default one is a globe icon. The icon is shown instead of a country flag when the phone number is in international format (i.e. starts with a `+` character) but is either incomplete or doesn't belong to any known country. Receives properties: * `title: string` — [ARIA](https://developer.mozilla.org/docs/Web/Accessibility/ARIA) label. * `aspectRatio: number` — Icon aspect ratio: `width / height`. * `className: string` — CSS class name. ## CDN One can use any npm CDN service, e.g. [unpkg.com](https://unpkg.com) or [jsdelivr.net](https://jsdelivr.net) ```html ``` Without country select: ```html ``` ## Country code A "country code" is a [two-letter ISO country code](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2) (like `US`). This library supports all [officially assigned](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2#Officially_assigned_code_elements) ISO alpha-2 country codes, plus a few extra ones like: `AC` ([Ascension Island](https://en.wikipedia.org/wiki/Ascension_Island)), `TA` ([Tristan da Cunha](https://en.wikipedia.org/wiki/Tristan_da_Cunha)), `XK` ([Kosovo](https://en.wikipedia.org/wiki/Kosovo)). To check whether a country code is supported, use [`isSupportedCountry()`](#issupportedcountrycountry-string-boolean) function. ## TypeScript This library comes with TypeScript "typings". If you happen to find any bugs in those, create an issue. ## Tests This component comes with 100% code coverage for the core `./source/helpers` directory. To run tests: ``` npm test ``` To generate a code coverage report: ``` npm run test-coverage ``` The code coverage report can be viewed by opening `./coverage/lcov-report/index.html`. If the code coverage report is "empty" then it means that a newer version of `handlebars` was accidentally installed and should be reverted to `handlebars@4.5.3`. The `handlebars@4.5.3` [work](https://github.com/handlebars-lang/handlebars.js/issues/1646#issuecomment-578306544)[around](https://github.com/facebook/jest/issues/9396#issuecomment-573328488) in `devDependencies` is for the test coverage to not produce empty reports: ``` Handlebars: Access has been denied to resolve the property "statements" because it is not an "own property" of its parent. You can add a runtime option to disable the check or this warning: See https://handlebarsjs.com/api-reference/runtime-options.html#options-to-control-prototype-access for details ``` ## GitHub On March 9th, 2020, GitHub, Inc. silently [banned](https://medium.com/@catamphetamine/how-github-blocked-me-and-all-my-libraries-c32c61f061d3) my account (erasing all my repos, issues and comments) without any notice or explanation.
