Veriff is an Estonian identity verification platform that analyses a large number of signals per session - document authenticity, liveness, biometric match, device and behavioral signals - and supports government-issued IDs from more than 230 countries. Its age verification use case extracts date of birth from the verified document, giving operators a high-confidence result backed by a global coverage footprint. A dedicated age-gating product layer sits on top of the core KYC stack and can be integrated standalone without a full KYC flow.

Priced for mid-market and enterprise volumes; cost may be a barrier for smaller or traffic-driven adult sites with thin per-user economics.
