The Notary Stamp / Seal

A notary stamp (or seal) is the official mark that confirms a document has been notarized. It serves as legal proof that the notarial act was completed by an authorized notary.

What the seal typically includes:

  • The notary's name
  • The commission number
  • The state or jurisdiction
  • The commission expiration date

Why the seal matters:

  • Confirms the authenticity of the notarization
  • Makes the document officially recognizable
  • Helps prevent tampering and fraud

A notarization is not complete without the official seal. Always keep your seal secure and never let anyone else use it — your seal represents your personal authority as a notary.
