Overview

What the Mobile Number Verification API does

A mobile number is the identifier every onboarding flow captures first and verifies least. The Mobile Number Verification API tells you whether the number is live, which operator and region it belongs to, and whether the name you hold matches the subscriber, giving you a strong, low-friction identity and reachability signal.

Use it to prioritise outreach, gate risky sign-ups and confirm that the number used for OTP belongs to the person you are onboarding.

Consent is part of the contract

Subscriber name matching uses personal data; capture the person's consent before running the match.

FAQ

Mobile Number Verification API: frequently asked questions

What teams ask before adding the Mobile Number Verification API to their integration.

It depends on the subscriber data available for the number. The response states clearly when a match could not be attempted.
