Install

npm install react-phone-number-input --save

If you're not using a bundler then use a standalone version from a CDN.

Use

The component requires two properties to be passed: value and onChange(value).

import 'react-phone-number-input/style.css'
import PhoneInput from 'react-phone-number-input'

return (
  <PhoneInput
    placeholder="Enter phone number"
    value={ this.state.phone }
    onChange={ phone => this.setState({ phone }) } />
)

value will be the parsed phone number, e.g. if a user chooses "United States" and enters (213) 373-4253 then value will be +12133734253.

To format value back to a human-readable phone number use formatPhoneNumber(value, format) function.

import { formatPhoneNumber } from 'react-phone-number-input'

if (value) {
  // Can be "National" or "International".
  formatPhoneNumber(value, "International")
}

CSS

The styles for this React component must be included on a page too.

When using Webpack

import 'react-phone-number-input/style.css'

It is also recommended to set up something like a postcss-loader with a CSS autoprefixer for supporting old web browsers (e.g. > 1%).

When not using Webpack

Get the style.css file from this package, optionally process it with a CSS autoprefixer for supporting old web browsers (e.g. > 1%), and then include the CSS file on a page.

<head>
  <link rel="stylesheet" href="/css/react-phone-number-input/style.css"/>
</head>

Validation

For phone number validation use libphonenumber-js's isValidNumber(value) function.

Autocomplete

Make sure to wrap a <PhoneInput/> into a <form/> otherwise web-browser's "autocomplete" feature may not be working: a user will be selecting his phone number from the list but nothing will be happening.

Custom country <select/>

One can supply their own country <select/> component in case the native one doesn't fit the app. Here's an example of using react-responsive-ui <Select/> component.

import 'react-phone-number-input/style.css'
import 'react-responsive-ui/style.css'

// Supplies custom `countrySelectComponent` property.
import PhoneInput from 'react-phone-number-input/react-responsive-ui'

return (
  <PhoneInput
    placeholder="Enter phone number"
    value={ this.state.phone }
    onChange={ phone => this.setState({ phone }) } />
)

Without country select

Some people requested an exported minimal phone number input component without country <select/>.

import PhoneInput from `react-phone-number-input/basic-input`

class Example extends Component {
  state = {
    value: ''
  }

  render() {
    // If `country` property is not passed
    // then "International" format is used.
    return (
      <PhoneInput
        country="US"
        value={ this.state.value }
        onChange={ value => this.setState({ value }) } />
    )
  }
}

Bug reporting

If you think that the phone number parsing/formatting/validation engine malfunctions for a particular phone number then follow the bug reporting instructions in libphonenumber-js repo.

API

React component

The available props are

  • value — Phone number in E.164 format. E.g. +12223333333 for USA.

  • onChange — Updates the value.

  • country — (optional) The country which is selected by default (can be set after a GeoIP lookup). E.g. US.

  • countries — (optional) Only the specified countries will be selectable. E.g. ['RU', 'KZ', 'UA'].

  • countryOptions - (optional) Can move some countries to the top of the list. E.g. ['US', 'CA', 'AU', '|', '...'].

  • flagsPath — (optional) A base URL path for national flag SVG icons. By default it loads flag icons from flag-icon-css github repo. I imagine someone might want to download those SVG flag icons and host them on their own servers instead.

  • flags — (optional) Supplies <svg/> elements for flags instead of the default <img src="..."/> ones. This might be suitable if someone's making an application which is supposed to be able to work offline (a downloadable app, or an "internal" website): import flags from 'react-phone-number-input/flags'.

  • flagComponent — (optional) A React component for displaying a country flag (replaces the default flag icons).

  • displayInitialValueAsLocalNumber — (optional) (see the example on the demo page) If set to true will display value phone number in local format when the component mounts or when value property is set after it has already been mounted. The default behaviour is false meaning that if initial value is set then it will be displayed in international format (e.g. +7 800 555 35 35). The reason for such default behaviour is that the newer generation grows up when there are no stationary phones and therefore everyone inputs phone numbers as international ones in their smartphones so people gradually get more accustomed to writing phone numbers in international form rather than in local form.

  • error — (optional) a String error message.

For the full list of all possible props see the source code. All other properties are passed through to the <input/> component.

Localization

Country names can be passed via the labels property. E.g. labels={{ RU: 'Россия', US: 'США', ... }}. This component comes pre-packaged with a couple of ready-made translations. Submit pull requests for adding new translations.

import ru from 'react-phone-number-input/locale/ru'

<PhoneInput ... labels={ru}/>

Extensions

Some users asked for phone extension input feature. It can be activated by passing ext property (a React.Element).

import React, { Component } from 'react'
import { Field, reduxForm } from 'redux-form'
import PhoneInput from 'react-phone-number-input'

class Form extends Component {
  render() {
    const ext = (
      <input
        value={ ... }
        onChange={ ... }
        type="number"
        noValidate />
    )

    return (
      <form onSubmit={ ... }>
        <PhoneInput
          value={ ... }
          onChange={ ... }
          ext={ ext } />

        <button type="submit">
          Submit
        </button>
      </form>
    );
  }
}

In a real-world application the ext property is most likely gonna be a basic-react-form <Field/>, or a redux-form <Field/>, or a react-final-form <Field/>.

The code above hasn't been tested, but it most likely works. Phone extension input will appear to the right of the phone number input. One can always skip using ext property and add a completely separate form field for phone number extension input instead.

{ number, ext } object can be converted to RFC3966 string for storing it in a database.

import { formatRFC3966 } from 'libphonenumber-js'

formatRFC3966({ number: '+12133734253', ext: '123' })
// 'tel:+12133734253;ext=123'

Use the accompanying parseRFC3966() function to convert an RFC3966 string into an object having shape { number, ext }.

import { parseRFC3966 } from 'libphonenumber-js'

parseRFC3966('tel:+12133734253;ext=123')
// { number: '+12133734253', ext: '123' }

Customizing

One can use the /custom export to import a bare <PhoneInput/> component and supply it with custom properties such as country select component and phone number input field component.

import PhoneInput from 'react-phone-number-input/custom'
import InternationalIcon from 'react-phone-number-input/international-icon'
import labels from 'react-phone-number-input/locale/ru'

<PhoneInput
  countrySelectComponent={...}
  inputComponent={...}
  internationalIcon={InternationalIcon}
  labels={labels}/>

countrySelectComponent

React component for the country select. See CountrySelectNative and CountrySelectReactResponsiveUI for an example.

Receives properties:

  • name : string? — HTML name attribute.
  • value : string? — The currently selected country code.
  • onChange(value : string?) — Updates the value.
  • options : object[] — The list of all selectable countries (including "International") each being an object of shape { value : string?, label : string, icon : React.Component }.
  • disabled : boolean? — HTML disabled attribute.
  • tabIndex : (number|string)? — HTML tabIndex attribute.
  • className : string — CSS class name.

inputComponent

React component for the phone number input field. See InputSmart and InputBasic for an example.

Receives properties:

  • value : string — The parsed phone number. E.g.: "", "+", "+123", "123".
  • onChange(value : string) — Updates the value.
  • country : string? — The currently selected country. undefined means "International" (no country selected).
  • metadata : objectlibphonenumber-js metadata.
  • All other properties should be passed through to the underlying <input/>.

Must also implement .focus() method.

Flags

Since this is a React component I thought that finding all country flags in SVG and including them as native React components as part of this library would be the best way to go. But then it truned out that when bundled all those country flags would take the extra 3 megabytes which is obviously not an option for a website (though it might be an option for an "internal" web application, or a desktop application built with Electron, or a mobile app).

So, including all country flags in the javascript bundle wouldn't be an option, and so all country flags are included as <img src="..."/> flags (by default the src points to flag-icon-css GitHub repo). And when using the (default) native country <select/> only the selected country flag icon is displayed therefore reducing footprint to the minimum.

For the same reasons the custom react-responsive-ui country <select/> doesn't show all country flag icons when expanded: otherwise the user would have to download all those flag icons when the country <select/> is expanded.

Reducing bundle size

By default all countries are included which means that libphonenumber-js loads the default metadata having the size of 75 kilobytes. This really isn't much but for those who still want to reduce that to a lesser size by generating their own reduced metadata set there is a possibility to pass custom metadata property to the react-phone-number-input/custom export.

For generating custom metadata see the guide in libphonenumber-js repo.

CDN

One can use any npm CDN service, e.g. unpkg.com or jsdelivr.net

<!-- `libphonenumber-js` (is used internally by `react-phone-number-input`). -->
<script src="https://unpkg.com/libphonenumber-js@1.2.15/bundle/libphonenumber-js.min.js"></script>

<!-- Either `react-phone-number-input` with "native" country `<select/>`. -->
<script src="https://unpkg.com/react-phone-number-input@2.0.0/bundle/react-phone-number-input-native.js"></script>

<!-- Or `react-phone-number-input` with `react-responsive-ui` `<Select/>`. -->
<script src="https://unpkg.com/react-phone-number-input@2.0.0/bundle/react-phone-number-input-react-responsive-ui.js"></script>

<!-- Styles for the component. -->
<link rel="stylesheet" href="https://unpkg.com/react-phone-number-input@2.0.0/bundle/style.css"/>

<!-- Styles for `react-responsive-ui` `<Select/> -->
<!-- (only if `react-responsive-ui` `<Select/>` is used). -->
<link rel="stylesheet" href="https://unpkg.com/react-responsive-ui@0.13.8/bundle/style.css"/>

<script>
  var PhoneInput = window['react-phone-number-input']
</script>
