PhoneID Suite

Discover how a user’s phone number can unlock their mobile identity to block fake accounts and prevent account compromise.

PhoneID Suite


TeleSign PhoneID returns data about your users based on their phone number. The PhoneID Suite consists of multiple REST APIs that you can use, depending on your preference and use case. PhoneID products can be used as a stand-alone service, or for better protection they can be used in conjunction with TeleSign Verify.

PhoneID products can identify the following attributes:

PhoneID Standard: Phone type, registration information, and telecom carrier.
PhoneID Contact: Name and address associated with the phone number.
PhoneID Live: Subscriber and device status, including roaming status and country for GSMA phones.

How it Works

The process is pretty simple. You make an API call, sending us the user's phone number, and we return data about the phone number. Here is a sample of the data we return:
