Swisscom

Swisscom Phone Number Validation API

Two-factor authentication API that starts an SMS token validation flow against an MSISDN and then verifies the token the user received. This is Swisscom's own SMS-OTP product, not the CAMARA Number Verification network API — it verifies possession of a handset by delivering a code, it does not perform network-based number verification.
