If you have ever tried to verify an account and been told your number "cannot be used", there is a good chance you were using a VoIP number. Understanding the difference is the key to verifications that actually work.
What is a VoIP number?
VoIP (Voice over IP) numbers are issued by internet calling services rather than mobile carriers. They are cheap and disposable, which is exactly why fraud-detection systems flag and block them.
What does non-VoIP mean?
A non-VoIP number is backed by a real mobile carrier and a physical SIM. To the service you are registering with, it looks identical to a normal phone, so it sails through verification.
Why it matters
AutoFications provides real, SIM-backed phone numbers. That is why our OTP delivery and success rates are dramatically higher than disposable VoIP alternatives.
