A notary stamp is an inked impression, usually round or rectangular, that shows the notary’s full name, their commission or registration details, and the jurisdiction they practise in. It sits right beside their signature. Many documents also carry a second mark, an embossed seal pressed into the paper rather than inked onto it, which raises a different question entirely: is that seal decoration or proof?
Quick recognition cues:
- Shape: round, rectangular, or a raised (embossed) circle with no ink at all
- Position: directly next to or beneath the signature, sometimes on an attached certificate
- Content: a name, a commission or registration number, and a jurisdiction
UK notaries typically pair an inked stamp with an embossed metal seal. US notaries lean almost entirely on the inked rubber stamp.
Key Takeaways
A genuine notary stamp shows a name, jurisdiction, and commission details in ink, while an embossed seal provides the tamper-resistant mark that international authorities actually rely on.
| Point | Details |
|---|---|
| Two marks, two jobs | An ink stamp identifies the notary; an embossed seal proves the document hasn’t been altered. |
| Check the core fields | Name, jurisdiction, and commission number should all be legible and consistent with each other. |
| US and UK differ sharply | US relies on inked stamps by state; UK pairs ink with a Faculty Office registered embossed die. |
| Verify before you trust | Cross-check any stamp against the official register rather than judging by appearance alone. |
| Compliant hardware exists | Stampdesign4u supplies custom rectangular and self-inking stamps for authorised legal professionals. |

What is a notary seal versus a notary stamp?
A notary stamp is the ink impression, the kind you get from a self inking or rubber stamp pad. A notary seal is a raised, embossed mark pressed into the paper with a metal die, no ink required. They are not interchangeable terms, even though people use them that way constantly.
- Ink stamp: fast, legible, easy to photocopy, standard for domestic paperwork
- Embossed seal: harder to forge, physically part of the paper, expected for international notarisation
- Permanence: ink can smudge or fade; an embossed impression stays in the paper fibres indefinitely
Pro Tip: In the UK, the embossed seal is usually the mark that matters for documents going abroad. In the US, the ink stamp is often the only mark a receiving clerk will look for. Know which one your document actually needs before you assume it’s missing something.
What details must appear on a genuine notary stamp?
A properly formed impression should contain most or all of these:
- The notary’s full legal name
- A title, usually “Notary Public” or simply “Notary”
- The city, county, or practising address
- A commission or registration number
- A commission expiry date, where the jurisdiction issues one
- The state, jurisdiction, or country of appointment
Requirements vary by jurisdiction, so a stamp missing an expiry date isn’t automatically fake. Some regions don’t issue one. What should worry you is a stamp with no name, no jurisdiction, or a jurisdiction that doesn’t match the notary’s stated location.
There are only around 850 practising notaries in England and Wales, a small enough pool that anomalies stand out quickly to anyone who checks. If a stamp looks sparse or generic, cross-check it against the official register for that jurisdiction rather than guessing.
What do common notary stamp shapes look like?
Four formats cover almost everything you’ll encounter on a real document.
- Round ink stamps: the most familiar shape, circular text running around a central name or seal design
- Rectangular rubber impressions: compact, often used where space is tight, common across US states
- Embossed metal seal impressions: raised, colourless, visible best under angled light rather than direct light
- Red or gold adhesive notarial seals: a coloured foil disc, sometimes embossed on top, used to reinforce a certificate
You’ll usually find the mark sitting directly beneath or beside the signature line. On more formal international documents, the impression can appear on a separate attached certificate, physically bound to the main paper with ribbon and sometimes a wax or foil seal over the knot. If you’re checking a scanned copy, a photograph taken at an angle will show an embossed seal far better than one taken flat on, since raised paper barely registers under direct overhead light.
How do US and UK notary stamps differ?
The two systems look and function quite differently, and confusing them causes most of the “is this real?” doubt people bring to a document.
United States: an inked rubber stamp is the primary mark. It shows the notary’s name, the state of commission, and a commission number. Requirements shift from state to state, so a Texas notary’s stamp won’t look identical to one from California, and you should check the issuing state’s own notary office if something looks unfamiliar.
United Kingdom: notaries combine an ink stamp with a bespoke steel-engraved embossed seal, registered with the Faculty Office of the Archbishop of Canterbury, the body that regulates all notaries public in England and Wales under the Legal Services Act 2007. For documents heading abroad, the certificate is often bound with ribbon and accompanied by an Apostille from the FCDO, which authenticates the notary’s seal and signature for use in Hague Convention countries.
The embossed seal carries real evidential weight overseas; a formal steel-engraved impression is harder to dispute than ink alone, which is largely why UK practice has kept it as standard for cross-border paperwork.
What do electronic and digital notary stamps look like?
An electronic notary mark usually shows up as an embedded stamp image on a PDF, accompanied by a digital certificate, a timestamp, and metadata identifying the signing session. Some platforms add a visible tamper-evident seal that changes appearance if the document is altered after signing.
Acceptance varies enormously by jurisdiction. Several US states permit remote online notarisation with clear statutory rules, while other countries have no framework for it at all. A convincing digital stamp image proves very little on its own; the certificate chain and audit trail behind it are what actually confirm validity. If you’re relying on a digitally notarised document, check with the receiving authority first rather than trusting the image alone.
How do you verify a notary stamp is genuine?
- Read the impression closely. Check the name, jurisdiction, and commission number are all present and legible.
- Search the official register. In England and Wales, that’s the Faculty Office; in the US, the relevant state’s notary database.
- Ask for the practising certificate. A genuine notary can produce proof of current registration on request.
- Confirm identity separately. Don’t rely on the stamp alone if the transaction carries real weight.
- Check for an Apostille when the document is going abroad. The FCDO authentication confirms the seal and signature are on file.
Pro Tip: When you call a notary’s registering body, have the exact commission number and jurisdiction ready. Registries move faster with a number to search than with a name alone, especially where names repeat.
Watch for blurred or smudged impressions, a missing commission number, or a jurisdiction that doesn’t match where the notary claims to practise. Any one of those is worth a follow-up call.
Quick checklist: what to look for right now
Before you accept a stamped document, run through this fast:
- Full name present and legible?
- Jurisdiction stated and correct?
- Commission number or expiry date visible?
- Embossed seal present, if the document is going overseas?
- Mark positioned near the signature, not floating unrelated on the page?
If any answer is no, don’t assume fraud. Contact the issuing notary or their registering body and ask for clarification before you proceed.
How are official notary seals actually made?
Ink stamps come from rubber dies or pre-inked pads, the same basic technology behind most office stamps. Embossed seals are a different animal entirely: a bespoke engraved steel die, custom cut and registered to a single named notary, pressed by hand into the paper with a metal embosser. Red or gold adhesive discs sometimes reinforce the embossed mark further.
Embossing is far harder to fake than ink because it physically alters the paper rather than sitting on top of it, and a registered die is linked directly to one notary’s identity in official records. Ribbon binding on certificates does something similar for multi-page documents, making pages harder to swap after signing.
Forging or misusing a notary’s seal isn’t a grey area. It’s a criminal offence in every jurisdiction with a notarial system worth the name, and no legitimate business will help you replicate one.
Recognising a genuine seal comes down to two habits, not one
Visual checks matter, but they only get you halfway there. A stamp can look entirely convincing and still belong to someone whose commission lapsed two years ago. Pairing what you see on the page with a quick registry lookup is the only combination that actually confirms anything, and it takes less time than most people assume.
Need a compliant stamp for legal or professional use?
If you’re a solicitor, notary, or authorised professional who needs a custom stamp that meets the visual standard clients expect, Stampdesign4u builds rectangular and self-inking impressions to your exact specification, without the wait times or minimum orders that come with traditional stamp suppliers.
Browse the personalised legal stamps range or go straight to a proven format like the Trodat 4927 rectangular stamp for a compliant, clearly laid-out impression. For guidance on where stamps fit into notarial practice more broadly, see the guide to legal stamps. Stampdesign4u only supplies stamp hardware to lawful, authorised purchasers and will not produce a stamp intended to replicate or impersonate an official notarial seal.
Frequently asked questions
What does a notary stamp look like on a typical document? It’s usually a round or rectangular ink impression sitting next to the signature, showing the notary’s name, jurisdiction, and a commission or registration number.
Is a notary seal the same as a notary stamp? No. A stamp is inked; a seal is embossed or raised into the paper without ink, and the two often appear together on the same document.
Do all notary stamps include an expiry date? Not always. Some jurisdictions issue commissions without a fixed expiry, so its absence alone doesn’t mean the stamp is invalid.
Why do UK notaries use an embossed seal as well as an ink stamp? The embossed seal, registered with the Faculty Office, carries stronger evidential weight for documents going abroad, particularly where an Apostille is required.
Are electronic notary stamps legally valid? Sometimes, depending on the jurisdiction. Visual cues like an embedded seal image only tell part of the story; the certificate and audit trail behind it determine actual validity.
