Phone Verification and OTP in Africa: How the Verify API Works

Verifying a phone number should not mean building OTP generation, delivery, retries, expiry and fraud controls yourself. eSMS Verify runs the whole flow behind two API calls.

Start and check

Call start with the user's number - eSMS generates a code and delivers it on a priority route. Call check with the code the user typed. That is the entire integration.

Built-in safety

Rate limiting, code expiry, hashing and anti-fraud checks are included, so you avoid the common OTP pitfalls (brute force, artificially inflated traffic).

Speed across Africa

OTPs route on priority paths to the local operators, so codes arrive in seconds - the difference between a completed signup and an abandoned one.
