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.
- 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

Download the latest version, or better yet install it with npm or Bower
-
Link the stylesheet
<link rel="stylesheet" href="path/to/intlTelInput.css">
- Override the path to flags.png in your CSS
.iti-flag {background-image: url("path/to/flags.png");}
Update: you will now also need to override the path to [email protected] (for retina devices). The best way to do this is to copy the media query at the end of intlTelInput.scss and update the path.
- Add the plugin script and initialise it on your input element
<input type="tel" id="mobile-number">
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="path/to/intlTelInput.min.js"></script>
<script>
$("#mobile-number").intlTelInput();
</script>
- Recommended: initialise the plugin with the
utilsScript
option to enable formatting/validation, and to allow you to extract full international numbers usinggetNumber
.
Note: any options that take country codes should be ISO 3166-1 alpha-2 codes
allowExtensions
Type: Boolean
Default: false
When autoFormat
is enabled, this option will support formatting extension numbers e.g. "+1 (702) 123-1234 ext. 12345".
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 (triggering a red flash in the input - see Troubleshooting to customise this). Requires the utilsScript
option.
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. Requires nationalMode
to be set to false
.
autoPlaceholder
Type: Boolean
Default: true
Add or remove input placeholder with an example number for the selected country. 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;
}
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 - requires the geoIpLookup
option - see example. When instantiating the plugin, we now return a deferred object, so you can use .done(callback)
to know when it is finished. If you leave defaultCountry
blank, it will default to the first country in the list. Note that if you choose to do the auto lookup, and you also happen to use the jquery-cookie plugin, it will store the loaded country code in a cookie for future use.
dropdownContainer
Type: String | false
Default: false
Appends the country list menu to a specific element. Example: dropdownContainer: 'body'
. This option is particularly useful for cases when the input is within a scrolling element or an element with overflow: hidden
. The menu is automatically closed on window
scroll to prevent positioning issues. If you want the menu to close when a different element is scrolled (such as the input's parent), simply listen for the scroll event on that element, and trigger $(window).scroll()
.
$('#scrollingElement').scroll(function() {
$(window).scroll();
});
excludeCountries
Type: Array
Default: undefined
Don't display the countries you specify.
geoIpLookup
Type: Function
Default: null
When setting defaultCountry
to "auto"
, we need to use a special service to lookup the location data for the user. Write a custom method to get the country code. For example if you use ipinfo.io:
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.
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.
numberType
Type: String
Default: "MOBILE"
Specify one of the keys from the global enum intlTelInputUtils.numberType
e.g. "FIXED_LINE"
to tell the plugin you're expecting that type of number. Currently this is only used to set the placeholder to the right type of number.
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.
utilsScript
Type: String
Default: ""
Example: "lib/libphonenumber/build/utils.js"
Enable formatting/validation etc. by specifying the path to the included utils.js script, 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 itself (intlTelInput.js) this will not work and you will need to use the loadUtils
method instead.
destroy
Remove the plugin from the input, and unbind any event listeners.
$("#mobile-number").intlTelInput("destroy");
getExtension
Get the extension part of the current number, so if the number was "+1 (702) 123-1234 ext. 12345"
this would return "12345"
.
var extension = $("#mobile-number").intlTelInput("getExtension");
Returns a string e.g. "12345"
getNumber
Get the current number in the given format (defaults to E.164 standard). The different formats are available in the enum intlTelInputUtils.numberFormat
- taken from here. Requires the utilsScript
option. Note that even if nationalMode
is enabled, this can still return a full international number.
var intlNumber = $("#mobile-number").intlTelInput("getNumber");
// or
var ntlNumber = $("#mobile-number").intlTelInput("getNumber", intlTelInputUtils.numberFormat.NATIONAL);
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. Requires the utilsScript
option.
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 - 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 = $("#mobile-number").intlTelInput("isValidNumber");
Returns: true
/false
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.
$("#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. Optionally pass a intlTelInputUtils.numberFormat
as the second argument if you want to specify national/international formatting (must be a valid number). Note that by default, if nationalMode
is enabled it will try to use national formatting.
$("#mobile-number").intlTelInput("setNumber", "+44 7733 123 456");
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"
}, ...]
A custom build of Google's libphonenumber which enables the following features:
- As-you-type formatting with
autoFormat
option, which prevents you from entering invalid characters - Validation with
isValidNumber
,getNumberType
andgetValidationError
methods - Placeholder set to an example number for the selected country - even specify the type of number (e.g. mobile) using the
numberType
option - Extract the standardised (E.164) international number with
getNumber
even when using thenationalMode
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).
To recompile Utilities Script see js-docs in top of utils.js.
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.
Customise invalid key flash
Set the colour like this (or set to none
to disable):
.intl-tel-input input.iti-invalid-key {background-color: #FFC7C7;}
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
Simply add this line to get input groups working properly.
.intl-tel-input {display: table-cell;}
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;}
I'm very open to contributions, big and small! For instructions on contributing to a project on Github, see this guide: Fork A Repo.
You will need to install Grunt to build the project, which relies on npm. You will also need evenizer (npm install -g evenizer
) and imagemagick to generate retina flag sprites. Then run npm install
to install Grunt etc, then grunt bower
to install other dependencies, then you should be good to run grunt build
to build the project. At this point, the included demo.html should be working. You should make your changes in the src
directory and be sure to run grunt build
again before committing.
If when building, you get an error in the "exec:evenizer" task, you may need to temporarily increase the ulimit by running this command: ulimit -S -n 2048
