Number Verify V2.1

Seamless and secure mobile number verification

Presentation

The NUMBER VERIFY V2.1 API allows application developers to verify, in real time, whether the mobile phone number used in a digital journey matches the number associated with the user's authenticated mobile device. For an online service, this check allows:

  • To validate a phone number (06...)
  • To retrieve the user's mobile phone number to authenticate them seamlessly in an internet journey (possession factor)
  • To replace sending a code via SMS

Two conditions for proper operation:

  • A user journey on a mobile device
  • A connection to the mobile network (3G/4G) of the device

How does it work?

  • NUMBER VERIFY

      1. 1

        User initiative

        The user carries out a transaction or journey on the internet using their mobile line.

      2. 2

        Consent request

        The merchant site or online service provider wants to authenticate the user's line. Consent is requested from the user.

      3. 3

        Verification result

        If the verification is successful, the user can proceed. Otherwise, the site chooses another authentication method.
