International Telephone Input

A jQuery plugin for entering and validating international telephone numbers. It adds a flag dropdown to any input, which lists all the countries and their international dial codes next to their flags.

Demo and Examples

You can view a live demo and some examples of how to use the various options here: http://jackocnr.com/intl-tel-input.html, or try it for yourself using the included demo.html.

Features

• Automatically format the number as the user types
• Automatically set the input placeholder to an example number for the selected country
• Navigate the country dropdown by typing a country's name, or using up/down keys
• Selecting a country from the dropdown will update the dial code in the input
• Typing a different dial code will automatically update the displayed flag
• Dropdown appears above or below the input depending on available space/scroll position
• Lots of initialisation options for customisation, as well as public methods for interaction

Browser compatibility

Getting Started

1. Download the latest version, or better yet install it with Bower: bower install intl-tel-input
2. Link the stylesheet (note that this references the image flags.png)

<link rel="stylesheet" href="build/css/intlTelInput.css">

3. Add the plugin script and initialise it on your input element (alternatively, use a script loader like RequireJS)

<input type="tel" id="mobile-number">

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="build/js/intlTelInput.min.js"></script>
<script>
  $("#mobile-number").intlTelInput();
</script>

Options

Note: any options that take country codes should be lower case ISO 3166-1 alpha-2 codes

autoFormat
Type: Boolean Default: true
Format the number on each keypress according to the country-specific formatting rules. This will also prevent the user from entering invalid characters. Requires the utilsScript option for the formatting logic.

autoHideDialCode
Type: Boolean Default: true
If there is just a dial code in the input: remove it on blur, and re-add it on focus. This is to prevent just a dial code getting submitted with the form.

defaultCountry
Type: String Default: ""
Set the default country by it's country code. You can also set it to "auto", which will lookup the user's country based on their IP address. Otherwise it will just be the first country in the list.

nationalMode
Type: Boolean Default: false
Don't insert the international dial code when the user selects a country from the dropdown. Useful if you want to accept numbers in national format, and then you can use getSelectedCountryData to get the selected country's dial code.

onlyCountries
Type: Array Default: undefined
Display only the countries you specify.

preferredCountries
Type: Array Default: ["us", "gb"]
Specify the countries to appear at the top of the list.

responsiveDropdown
Type: Boolean Default: false
Set the dropdown's width to be the same as the input. This is automatically enabled for small screens.

utilsScript
Type: String Default: "" Example: "lib/libphonenumber/build/utils.js"
Enable formatting/validation/example numbers (for placeholders) by specifying the URL to the included utils.js script (~200KB), which is fetched only when the page has finished loading (on window.load) to prevent blocking. See Utilities Script for more information. Note that if you're lazy loading the plugin script (after the window.load event) this will not work and you will need to use the loadUtils method instead.

Public Methods

destroy
Remove the plugin from the input, and unbind any event listeners.

$("#mobile-number").intlTelInput("destroy");

getCleanNumber
Get the current number formatted to the E.164 standard. Requires the utilsScript option. Note that even if nationalMode is enabled, this will still return an international number, as specified by the E.164 standard.

var cleanNumber = $("#mobile-number").intlTelInput("getCleanNumber");

Returns a string e.g. "+17024181234"

getNumberType
Get the type (fixed-line/mobile/toll-free etc) of the current number. Requires the utilsScript option.

var numberType = $("#mobile-number").intlTelInput("getNumberType");

Returns an integer, which you can match against the various options in the global enum intlTelInputUtils.numberType e.g.

if (numberType == intlTelInputUtils.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 flag.

var countryData = $("#mobile-number").intlTelInput("getSelectedCountryData");

Returns something like this:

{
  name: "Afghanistan (‫افغانستان‬‎)",
  iso2: "af",
  dialCode: "93"
}

getValidationError
Get more information about a validation error.

var error = $("#mobile-number").intlTelInput("getValidationError");

Returns an integer, which you can match against the various options in the global enum intlTelInputUtils.validationError e.g.

if (error == intlTelInputUtils.validationError.TOO_SHORT) {
    // the number is too short
}

isValidNumber
Validate the current number using Google's libphonenumber (requires the utilsScript option). Expects an internationally formatted number (unless nationalMode is enabled).

var isValid = $("#mobile-number").intlTelInput("isValidNumber");

Returns: true/false

loadUtils
Load the utils script - either pass the path as an argument, or it will default to the value of the utilsScript option. Use this if you're lazy loading the plugin script (in which case the utilsScript option will not work as it relies on the window.load event).

$("#mobile-number").intlTelInput("loadUtils", "lib/libphonenumber/build/utils.js");

selectCountry
Change the country selection (e.g. when the user is entering their address).

$("#mobile-number").intlTelInput("selectCountry", "gb");

setNumber
Insert a number, and update the selected flag accordingly.

$("#mobile-number").intlTelInput("setNumber", "+44 7733 123 456");

Static Methods

getCountryData
Get all of the plugin's country data.

var countryData = $.fn.intlTelInput.getCountryData();

Returns an array of country objects:

[{
  name: "Afghanistan (‫افغانستان‬‎)",
  iso2: "af",
  dialCode: "93"
}, ...]

setCountryData
Set all of the plugin's country data.

$.fn.intlTelInput.setCountryData(countryData);

Utilities Script

International number formatting/validation is hard (it varies by country/district). The only comprehensive solution I have found is Google's libphonenumber, which I have precompiled into a single JavaScript file and included in the lib directory. Unfortunately even after minification it is still ~200KB, so I have included it as an optional extra. If you specify the utilsScript option then it will fetch the script only when the page has finished loading (to prevent blocking), and allows you to use the public isValidNumber function, autoFormat mode and will automatically update your input's placeholder to an example number for the selected country.

Troubleshooting

Image path
Depending on your project setup, you may need to override the path to flags.png in your CSS.

.intl-tel-input .flag {background-image: url("path/to/flags.png");}

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

.intl-tel-input {width: 100%;}

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 intl-tel-input).

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 intl-tel-input).

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
In order to get the automatic country-specific placeholders, simply omit the placeholder attribute on the <input>.

Contributing

I'm very open to contributions, big and small! For instructions on contributing to a project on Github, see this guide: Fork A Repo.

I use Grunt to build the project, which relies on npm. In the project directory, run npm install to install Grunt (and other dependencies), then make your changes in the src directory and run grunt build to build the project.
