Swisscom Phone Number Validation API is one of 14 APIs that [Swisscom](https://apis.io/providers/swisscom/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Verification, Two-Factor Authentication, SMS, and OTP. The published artifact set on APIs.io includes API documentation and an API reference.

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.
