What Is SMS Verification?
SMS verification (also called SMS OTP or phone verification) is a process where a platform sends a one-time password (OTP) to a phone number you provide. You enter that code to prove you have access to the phone number, completing the verification.
It's used by almost every major platform — WhatsApp, Google, Instagram, Telegram, Facebook, Discord, Twitter, and thousands more — to confirm new account registrations and add an extra layer of security.
