Phone Number Validation

Use the Phone Number Validation Settings to configure your app to check the phone number your users enter without depending on SMS or WhatsApp for validation and verification.

Under the hood, the Phone Number Validation Settings uses the libphonenumber library. The library can parse, format, and validate phone numbers for all countries/regions in the world.

To access Phone Number Validation settings in your Authgear project, navigate to Authentication > Login Methods in the Authgear Portal.

Next, select a login method that uses mobile phone number as login ID (e.g., Mobile, Mobile/Email, or Custom with phone number enabled as login ID). Then, scroll down to the Phone Number Validation section. Select validate phone number with libphonenumber or validate only the country code and phone number length.

Enable phone number validation with libphonenumber

Note: The phone number validation logic may become outdated due to recent changes in the numbering style in certain countries/regions. In such a case, you can disable the Phone Number Validation feature to enable users to register new numbers that the logic is unable to recognize.
