Getting Started

  1. Download the latest release, or better yet install it with npm or Bower

  2. Include the stylesheet

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

  3. Override the path to flags.png in your CSS

    .iti-flag {background-image: url("path/to/flags.png");}
@media only screen and (-webkit-min-device-pixel-ratio: 2), only screen and (min--moz-device-pixel-ratio: 2), only screen and (-o-min-device-pixel-ratio: 2 / 1), only screen and (min-device-pixel-ratio: 2), only screen and (min-resolution: 192dpi), only screen and (min-resolution: 2dppx) {background-image: url("path/to/flags@2x.png");}

  4. Add the plugin script and initialise it on your input element

    <input type="tel" id="phone">

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="path/to/intlTelInput.js"></script>
<script>
$("#phone").intlTelInput();
</script>
  5. Recommended: initialise the plugin with the utilsScript option to enable formatting/validation, and to allow you to extract full international numbers using getNumber.

Recommended Usage

We highly recommend you load the included utils.js using the utilsScript option. Then even when nationalMode or separateDialCode is enabled, the plugin is built to always deal with numbers in the full international format (e.g. "+17024181234") and convert them accordingly. I recommend you get, store, and set numbers exclusively in this format for simplicity.

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 it will automatically set the country and format it according to the options you specify (e.g. if you enable nationalMode it will automatically remove the international dial code for you).

Options

Note: any options that take country codes should be 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 flag is not clickable. Also we display the selected flag on the right instead because it is just a marker of state.

autoFormat [REMOVED]
Automatically format the number as the user types. Unfortunately this had to be removed for the reasons listed here: #346 Disable and remove autoFormat feature.

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

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 utilsScript option.

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

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

dropdownContainer
Type: String Default: ""
Expects a jQuery selector e.g. "body". Instead of putting the country dropdown next to the input, append it to the element specified, and it will then be positioned absolutely next to the input using JavaScript. This is useful when the input is inside a container with overflow: hidden. Note that the absolute positioning can be broken by scrolling, so it will automatically close on the window scroll event. If you have a different scrolling element that is causing problems, simply listen for the scroll event on that element, and trigger $(window).scroll() e.g.

$("#scrollingElement").scroll(function() {
  $(window).scroll();
});

excludeCountries
Type: Array Default: undefined
Don't display the countries you specify.

formatOnDisplay
Type: Boolean Default: true
Format the input value (according to the nationalMode option) during initialisation, and on setNumber. Requires the utilsScript option.

geoIpLookup
Type: Function Default: null
When setting initialCountry to "auto", you must use this option to specify a custom function that looks up the user's location. Also note that when instantiating the plugin, we now return a deferred object, so you can use .done(callback) to know when initialisation requests like this have completed.

Here is an example using the ipinfo.io service (note: this service requires a paid account to use over HTTPS): 

geoIpLookup: function(callback) {
  $.get("http://ipinfo.io", function() {}, "jsonp").always(function(resp) {
    var countryCode = (resp && resp.country) ? resp.country : "";
    callback(countryCode);
  });
}

Note that the callback must still be called in the event of an error, hence the use of always in this example.
Tip: store the result in a cookie to avoid repeat lookups!

initialCountry
Type: String Default: ""
Set the initial country selection by specifying it's country code. You can also set it to "auto", which will lookup the user's country based on their IP address (requires the geoIpLookup option - see example). Note that the "auto" option will not update the country selection if the input already contains a number.

If you leave initialCountry blank, it will default to the first country in the list.

nationalMode
Type: Boolean Default: true
Allow users to enter national numbers (and not have to think about international dial codes). Formatting, validation and placeholders still work. Then you can use getNumber to extract a full international number - see example. This option now defaults to true, and it is recommended that you leave it that way as it provides a better experience for the user.

placeholderNumberType
Type: String Default: "MOBILE"
Specify one of the keys from the global enum intlTelInputUtils.numberType e.g. "FIXED_LINE" to set the number type to use for the placeholder.

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

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

preventInvalidNumbers [REMOVED]
Prevent the user from entering invalid characters. Unfortunately this had to be removed for the reasons listed here: #79 Limit Input Characters to Formatted String Length.

separateDialCode
Type: Boolean Default: false
Display the country dial code next to the selected flag so it's not part of the typed number. Note that this will disable nationalMode because technically we are dealing with international numbers, but with the dial code separated.

utilsScript
Type: String Default: "" Example: "build/js/utils.js"
Enable formatting/validation etc. by specifying the URL of the included utils.js script (or alternatively just point it to the file on cdnjs.com). The script is fetched using Ajax when the page has finished loading (on the window.load event) to prevent blocking. When instantiating the plugin, we return a deferred object, so you can use .done(callback) to know when initialisation requests like this have finished. See Utilities Script for more information. Note that if you're lazy loading the plugin script itself (intlTelInput.js) 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. 

$("#phone").intlTelInput("destroy");

getExtension
Get the extension from the current number. Requires the utilsScript option.

var extension = $("#phone").intlTelInput("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). The different formats are available in the enum intlTelInputUtils.numberFormat - which you can see here. Requires the utilsScript option. 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. 

var intlNumber = $("#phone").intlTelInput("getNumber");
// or
var ntlNumber = $("#phone").intlTelInput("getNumber", intlTelInputUtils.numberFormat.E164);

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 = $("#phone").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 = $("#phone").intlTelInput("getSelectedCountryData");

Returns something like this:

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

getValidationError
Get more information about a validation error. Requires the utilsScript option. 

var error = $("#phone").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 - see example. Expects an internationally formatted number (unless nationalMode is enabled). If validation fails, you can use getValidationError to get more information. Requires the utilsScript option. Also see getNumberType if you want to make sure the user enters a certain type of number e.g. a mobile number. 

var isValid = $("#phone").intlTelInput("isValidNumber");

Returns: true/false

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

$("#phone").intlTelInput("setCountry", "gb");

setNumber
Insert a number, and update the selected flag accordingly. Note that if formatOnDisplay is enabled, this will attempt to format the number according to the nationalMode option. 

$("#phone").intlTelInput("setNumber", "+447733123456");

Static Methods

getCountryData
Get all of the plugin's country data - either to re-use elsewhere e.g. to populate a country dropdown - see example, or to modify - see example. Note that any modifications must be done before initialising the plugin. 

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

Returns an array of country objects:

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

loadUtils
Note: this is only needed if you're lazy loading the plugin script itself (intlTelInput.js). If not then just use the utilsScript option.
Load the utils.js script (included in the lib directory) to enable formatting/validation etc. See Utilities Script for more information.

$.fn.intlTelInput.loadUtils("build/js/utils.js");

setCountryData [REMOVED]
Set the plugin's country data. This method was removed because it makes much more sense to just use getCountryData and then modify that (see example) instead of having to generate the whole thing yourself - the country data has become increasingly complicated and for each country we now have five properties: the name, iso2 country code, international dial code, priority (in case two countries have the same international dial code), and finally a list of area codes used in that country - see data.js for more info.

Events

You can listen for the following events on the input.

countrychange
This is triggered when the user selects a country from the dropdown.

$("#phone").on("countrychange", function(e, countryData) {
  // do something with countryData
});

See an example here: Country sync

Utilities Script

The utilities script (build/js/utils.js) is a custom build of Google's 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 I have found is libphonenumber, which I have precompiled into a single JavaScript file and included in the lib directory. Unfortunately even after minification it is still ~215KB, but if you use the utilsScript option then it will only fetch the script when the page has finished loading (to prevent blocking). If size is not a concern, then you can manually include the script yourself however you like, and as long as it has loaded before you initialise the plugin then it should work fine.

To recompile the utilities script yourself, see the comments at the top of src/js/utils.js.

Troubleshooting

Submitting the full international number when in nationalMode
If you're submitting the form using Ajax, simply use getNumber to get the number before sending it. If you're using the standard form POST method, you have two options. The easiest thing to do is simply update the input value using getNumber in a submit handler: 

$("form").submit(function() {
  myInput.val(myInput.intlTelInput("getNumber"));
});

But this way the user will see their value change when they submit the form, which is weird. A better solution would be to update the value of a separate hidden input, and then read that POST variable on the server instead. See an example of this solution here.

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>.

Bootstrap input groups
A couple of CSS fixes are required to get the plugin to play nice with Bootstrap input groups. You can see a Codepen here.
_Note: there is currently a bug 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: .intl-tel-input .iti-flag .arrow {border: none;}_
