The “Number Verification” API is a service that enables businesses to seamlessly confirm the ownership of a mobile phone number and retrieve the number directly from the user’s device.

 

Two mechanisms are leveraged to obtain the information:

• Network-based: Network operator knows to which subscriber a network-connected mobile phone belongs and what its associated phone number is or,
• SIM-based: Authentication mechanism based on the identification of the subscriber’s SIM installed in the user’s device.

This API ensures that the phone number provided or obtained matches the one associated with the user’s device, enabling secure and reliable authentication. This API eliminates the need for manual inputs, such as SMS codes, simplifying processes like account creation, login, or transaction validation. It offers a practical solution for industries requiring accurate phone number verification and retrieval, enhancing both user experience, fraud prevention and operational efficiency.
