What Is Phone Number Verification?

The phone number verification confirms the client’s phone number’s identity – valid or fake. Consider an example – whenever you sign up for a website, they ask for a phone number to let you in. Once you share your number, they’ll shoot a special code straight to your phone. When you tap in that secret code, they know it’s you stepping in, not some sneaky impostor trying to spoil the fun.

Phone number verification done with APIs and software tools is a comprehensive approach to enhance security, improve communication, and ensure regulatory compliance. Its benefits extend to both businesses and users.

How Does Phone Verification Work?
