Getting Started

This document provides an overview of the Sinch Verification (SMV) service and its phone number verification capabilities.

The Sinch Verification platform enables businesses to verify end-user phone numbers securely using SDKs and cloud-based backend services integrated with mobile or web applications.

The service supports seamless verification methods, including Data Verification, which validates a user’s phone number through mobile carrier infrastructure with minimal or no user interaction.

This documentation includes the API specifications, verification flow details, integration guidelines, authentication methods, request/response structures, and functional behavior required to integrate Sinch Verification services into your applications.

The Sinch Verification APIs can be consumed directly from backend systems or through Sinch mobile SDKs for Android, iOS, and web applications.

Integrating the Sinch Verification APIs and SDKs with your backend systems enables secure, scalable, and frictionless user authentication experiences while improving onboarding and reducing verification complexity.
