Notarized

Verify a sealed document.

Every document sealed on Notarized carries a QR code and a seal code. Scan the code, or enter it below, to open the public verification page. No account needed.

The seal code is printed beside the QR code on the sealed copy and on the certificate of completion.

The public verification page: seal valid, the document, the notary and commission, the timestamp, the signers and a passing tamper check.

Sample data.

What the page checks.

The seal is a chain of checks, not a picture of a stamp. The verification page runs them again every time it is opened.

  • IntegrityThe file's SHA-256 hash is recomputed and compared with the one sealed into the record. Genuine or altered, nothing in between.
  • TimestampThe RFC 3161 timestamp from an independent time authority, recorded when the seal was applied.
  • NotaryThe commissioning state, commission number and expiration of the notary who performed the act.
  • SignersWho signed, when they consented to sign electronically, and the audit events behind each signature.
