Certificate verification

Verify a certificate

Scan the QR code on the certificate, or enter the verification code printed below it.

12 letters and digits, e.g. K7QD-9XMP-T3AB. The certificate number is not the verification code.

Every certificate is listed in our register and sealed with an Ed25519 digital signature at issuance. Our public key lets anyone check the seal independently.
