AgeOnce is a privacy-first age verification API and WordPress plugin for businesses. A visitor proves their age with a government ID and a liveness check. The website or app receives a signed 18+ or 21+ result and an Audit ID. ID images and face photos are not stored on the customer’s servers.
It is used for adult content, alcohol, tobacco, vape, and gambling flows under US state age-verification laws, the UK Online Safety Act, and the EU Digital Services Act. Returning visitors can be re-checked without uploading the same document again.
