CERTASTAMP™ Certified Evidence Object · Public Verification
— Public Registry —

CertaStamp verification.

This endpoint exists to resolve QR codes printed on Certified Evidence Objects — emails, attachments, and fax cover pages — issued by the CertaStamp platform. It is not a general-purpose website.

§ How It Works

Scan the QR on a document to verify it.

Each CertaStamp-certified document carries a machine-readable QR code. Pointing any standard camera or QR-reader app at that code will redirect you here with the document’s letter id and cryptographic signature embedded. If the signature matches our sealed record, you will see a green receipt. If it does not match, or if the document has been altered, you will see a red rejection.
