Prove review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

Prove is a cloud identity-verification and authentication suite for mid-market and enterprise organizations. Its phone-centric approach verifies identity attributes and phone-number ownership, evaluates phone reputation and behavioral risk, and supports customer onboarding and ongoing interactions. Banking, fintech, healthcare, insurance, marketplace, and online-gaming teams can use it to verify mobile identity signals without relying on document scans or selfies.

The product’s strongest focus is mobile possession and phone intelligence. Prove can passively authenticate possession of a mobile device, send clickable authentication links by SMS, and issue SMS or voice one-time passcodes. It also enriches customer records with verified contact information and monitors identity records and changes over time. Sanctions and politically exposed person screening extend the workflow beyond phone checks, while carrier and mobile-network data contribute to its identity signals. These capabilities suit fraud-prevention and account-access flows where a verified phone relationship is central.

Implementation is built around APIs, with client-side and server-side SDKs available for integration. Prove is sold through a contact-sales model, so teams should plan for a sales-led purchasing process rather than selecting a published self-serve tier. GDPR support is listed, and documentation is the stated support channel. Organizations needing document capture, facial comparison, or liveness detection should choose a broader identity-verification platform; Prove is better suited to teams prioritizing phone ownership, mobile authentication, reputation checks, and monitoring within an API-led stack.
