Phone ID - Overview

Telesign Phone ID allows you to get detailed and actionable global phone number and subscriber data intelligence to strengthen authentications, evaluate fraud risks, and enhance the user experience.

Answer critical questions about users by using their phone numbers to get actionable data intelligence about their device, contact information, and more. Phone number data intelligence can help strengthen and validate the user verification process, reduce fake accounts, inform risk models, improve conversions and accuracy of collected information, and even determine the optimal channel for message delivery.

The basic Phone ID product cleans and reformats a submitted phone number and then returns phone device-type, telecom carrier name, and phone registration information. You can also configure it to return additional identity attributes, some of which must be purchased separately.
