Multiple Age Verification Methods, One API

Ideal for low-friction age checks in the US and UK. The user’s name and address are matched against trusted consumer and public records to confirm age without requiring document upload.

Name & Last Four of SSN (US)
Designed for higher-confidence verification in regulated environments. The user provides their name and the last four digits of their SSN, which are used to confirm age through authoritative identity data sources.

Photo ID (Global)
Ideal for regulated industries requiring documented proof of age. The user uploads a government-issued ID, which is automatically checked for authenticity and used to extract date of birth. When required, biometric checks may be applied to confirm ownership.
