International Telephone Input for Angular (NgxIntlTelInput)

Forked from

All Contributors

Build Status npm version npm

An Angular package for entering and validating international telephone numbers. It adds a flag dropdown to any input, detects the user's country, displays a relevant placeholder and provides formatting/validation methods.



Validation with google-libphonenumber

ngx-intl-tel-input-gg Angular ngx-bootstrap
1.x.x 9.x.x - 17.x.x 6.0.0


Install Dependencies

$ npm install intl-tel-input@17.0.3 --save

$ npm install google-libphonenumber --save

$ ng add ngx-bootstrap

If you do not wish to use Bootstrap's global CSS, we now package the project with only the relevant bootstrap styling needed for the dropdown. As such, you can remove the bootstrap styling from angular.json.

Further, Angular CLI should tree-shake the rest of Ngx-Boostrap away if you don't utilize other dependencies from the bootstrap package. This should keep this dependency a lean feature-add

Add Dependency Style

Add 'intl-tel-input' style file:


to angular.json styles array:

"styles": [

Install This Library
