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.

What PDF Verified is, and what it is not

Electronic signature law is settled in broad terms and specific in the details. The ESIGN Act, UETA, eIDAS and their equivalents recognise electronic signatures across more than 190 countries, and what decides a particular case is intent to sign plus evidence connecting the signature to the signer, which is what the audit certificate records. Certain document types carry their own formalities wherever you are: deeds, wills, some property instruments, and anything requiring a witness or a notary. Sign only what you are authorised to sign, since applying another person signature without their authority is forgery whatever tool is used.

PDF Verified is a tool for preparing, signing, stamping and checking documents. It is not a law firm, a compliance service or a forensic examiner, and nothing here is legal, financial or compliance advice. Requirements differ by country, by document type and by the party asking, so check what applies to your document before you rely on it, and take advice where the document matters. You are responsible for the documents you create, sign and send, and for having the authority to do so: signing or stamping in somebody else name, or as an organisation you do not represent, is forgery whatever tool is used. To the extent the law allows, we accept no liability for how a document made with this tool is used or relied on. The full position is in our terms of service.
