What is Notary Stamp?

The official seal a notary public applies to attest they witnessed a signing or certified a document.

A notary stamp (or notary seal) is the mark a notary public applies to show they have officially witnessed a signature, administered an oath, or certified a copy. It identifies the notary, their commission, and often an expiry date. With the growth of remote online notarization (RON), notary stamps are increasingly digital. PDF Verified supports notary-style stamps with serial numbers, locked metadata, and public verification — though formal RON commissioning rules vary by jurisdiction and should be checked locally.

Notary stamp vs notary signature

A notarization usually requires both the notary's signature and their official stamp. The stamp conveys the commission details; the signature conveys the act. PDF Verified captures both as separate fields, each logged in the audit trail.

Remote online notarization (RON)

Many jurisdictions now permit notarization over audio-video with a digital seal. Where permitted, a PDF Verified digital notary stamp with serial + QR verification provides the verifiable seal RON requires. Always confirm your jurisdiction's RON rules and commissioning requirements.
