Number Verify

1.1.1

Number Verify checks if the phone number in use matches the one provided by the customer. This is performed silently at the network level to make the user onboarding journey frictionless and secure. This is an alternative to SMS OTPs, which are prone to social engineering attacks and can add friction to the user experience.

Description This API follows the GSMA Mobile Connect standard of Verified MSISDN.

How it works

  1. A customer tries registering for a new app and is requested to enter their phone number.
  2. The app sends the phone number via the Number Verify API to Vodafone.
  3. The Number Verify API checks in real-time whether the phone number connected to the network matches what the user has entered.
  4. The API responds with True/False as to whether the MSISDN matches, e.g. "device_msisdn_verified": false
Note
Customers must be on the cellular network to perform a successful verification.
