Verify a certificate or membership

Enter the reference printed on the document, or paste the full verification link. You can also scan the QR code on the certificate with your phone's camera to come straight here. No account is needed.

The reference is the long code printed under Reference on the document, and it also appears in the link beneath the QR code.

Older certificate without a QR code?

Certificates issued before this service carry a serial number instead, such as 518. Enter that number together with the surname of the person it was issued to.

Serial number

Holder's surname

Both the number and the surname must match. We ask for the surname so that the list of past certificates cannot be read by guessing numbers.
