Got questions?

  • What is Data Verification?

    Mobile Data Verification is a highly secure mobile number verification method that’s directly integrated into carrier networks. It offers a smooth user experience and gives users quick access to your platform.

  • How does Data Verification work?

    Using information held by the operator, we match a user’s phone number with the mobile network carrier’s data to verify identity. This takes less than 5 seconds. The user only needs to consent; no further action is needed.

  • How does Data Verification differ from other methods?

    Unlike most methods, Data Verification doesn't require users to enter a PIN or any private info to get verified. The verification happens behind the scenes, and isn't visible to end-users. This removes the risk of errors and social engineering. 

  • Can Data Verification be combined with other methods?

    Yes, Sinch verification methods can be mixed and matched based on use cases and business goals. 

    To offer the smoothest customer UX, identify the best verification method for each customer journey. Data Verification is not suitable for all markets or applications, but with Unified Verification, it's easy to combine and access all Sinch verification products from one API.
