A notary stamp is the official mark a commissioned notary applies to a document to show it has been notarised. It records the notary’s name, jurisdiction and authority in ink, providing visual proof that identity and signature checks took place. In the UK and US, that record supports different legal effects, so the same-looking stamp can mean different things depending on where it’s used.
TL;DR:
- A notary stamp primarily serves to visually verify that a notarial act has taken place, but legal authority depends on the notary’s valid commission.
- Embossed seals are harder to forge and do not contain ink, while inked stamps are easier to reproduce on photocopies and scans.
- Verifying a notary involves checking the name, jurisdiction, expiry date, and registry status from official government registers.
- Purchasing a notary stamp is legal; however, only appointed and licensed notaries can lawfully perform notarizations, regardless of hardware ownership.
- Notary practice varies by jurisdiction, with UK notaries registered officially and US states setting their own rules, but the stamp’s presence alone does not prove authenticity or legality.

What does a notary stamp look like?
Most notary stamps fall into three physical types: self-inking stamps (the most common in offices), traditional rubber stamps requiring a separate ink pad, and embossed seals that press a raised design into paper without ink. Each does the same job, showing a document has passed through a notary’s hands.
A genuine impression usually includes:
- The notary’s full name, exactly as commissioned
- The jurisdiction or state/country of appointment
- A commission number or registration reference
- The commission’s expiry date
- Wording identifying the person as a “Notary Public” (or the equivalent in that jurisdiction)
On photocopies and scans, ink impressions can blur or lighten, which is why some jurisdictions still favour an embossed seal that leaves a physical indent visible even without colour. Digital notary seals, used increasingly in remote online notarisation, often embed metadata that a verifier checks electronically rather than by eye, since a screenshot of a digital seal proves nothing on its own.
Fact check: an embossed seal carries no ink at all. If you’re checking a photocopy for authenticity and see only a faint circular outline with no colour, that’s often the seal working exactly as designed, not a printing fault.
Notary stamp versus notary seal: what’s the real difference?
An inked stamp deposits colour onto the page; an embossed seal presses a raised pattern into the paper’s fibres using a metal die. Both can appear on the same document, and in several jurisdictions, they’re expected to.
- Inked stamps photocopy and scan more reliably, since the colour reproduces even on cheap copiers.
- Embossed seals are harder to forge convincingly because replicating the metal die and the exact pressure pattern takes specialist equipment.
- Jurisdictional preference varies: UK notaries register a personal seal tied to their appointment, while many US states rely primarily on the inked stamp for day-to-day notarial acts.
For anyone verifying a document, the embossed seal is generally the tougher one to fake, but it’s also the harder one to spot on a low-quality scan. That trade-off is precisely why serious international paperwork often carries both marks rather than relying on just one.
How does a notary stamp authenticate a document?
The stamp itself doesn’t create legal authority; the notarial act does. A notary witnesses a signature, checks identity documents, and sometimes administers an oath or takes an acknowledgement. The stamp then visually records that this process happened, alongside a written certificate spelling out exactly what the notary did and when.
Authentication exists to save courts and institutions from having to independently verify a document’s origin. As the American Bar Association explains, a proper seal or stamp lets an authority accept a document as genuine without further inquiry.
That’s not the end of the story for documents crossing borders, though:
- A notary stamp alone often isn’t enough for use abroad
- Many countries require an apostille or legalisation step confirming the notary’s signature and seal match official records
- In the US, certain sealed public documents qualify as self-authenticating under Federal Rule of Evidence 902, meaning courts accept them without additional testimony, though jurisdictional rules still apply
United Kingdom rules: Faculty Office, registered seals and apostilles
In England and Wales, “notary public” is a protected title. Notaries are appointed and regulated by the Master of the Faculties, a role distinct from being a solicitor, even though some professionals hold both qualifications.
Every UK notary registers a personal seal with the Faculty Office, and that registration is what makes the mark meaningful beyond the notary’s own office. It’s not a generic rubber design bought off a shelf; it’s an identifier tied to a specific, checkable appointment.
- The Legalisation Office attaches an apostille confirming a notary’s signature, stamp or seal matches official records, but only for documents signed by a UK-qualified notary, solicitor or official
- Whether legalisation is needed at all depends on whether the destination country has signed the Hague Convention
- British consulates generally don’t provide notarial services themselves; guidance points people toward finding a qualified notary locally or abroad instead
If you’re arranging documents for use overseas, this UK notary seal guide walks through how the registered seal feeds into the apostille process step by step.
United States practice: state variation and evidentiary effect
US notarial acts typically cover acknowledgements, jurats (where the signer swears to the content), and copy certifications.
Because notary law sits at state level, requirements differ sharply from one state to another:
- Some states mandate a particular stamp size or ink colour
- Remote online notarisation, permitted in a growing number of states, allows electronic seals and signatures instead of a physical impression
- Under Federal Rule of Evidence 902, certain sealed and signed public documents are treated as self-authenticating in federal court, which reduces the need for separate proof of genuineness
That last point matters for anyone assuming a notary stamp is purely ceremonial. In the right context, it carries genuine evidentiary weight in litigation.
How do you verify a notary stamp or seal?
Checking an unfamiliar stamp doesn’t need to be guesswork. Work through it in order:
- Read the name, jurisdiction and expiry date printed on the impression, and confirm none has lapsed.
- Compare the printed name against the signature on the document; a mismatch is an immediate red flag.
- Search the relevant registry (the Master of the Faculties register in England and Wales, or the equivalent state Secretary of State database in the US) to confirm the person is currently commissioned.
- If anything looks inconsistent, request the underlying notarial certificate or contact the issuing authority directly rather than relying on the stamp alone.
Forged stamps have turned up in real fraud cases involving fraudulent bonds and property documents, so a moment’s scepticism is never wasted.
Pro Tip: Keep a note of the notary’s commission number when you receive a document. If a dispute arises months later, that single detail makes tracing the original registration far faster than trying to re-read a faded impression.
Can you buy a notary stamp, and who’s actually allowed to use one?
Yes, stamp devices themselves are freely available to purchase from stamp suppliers, including Stamp Design 4U’s own catalogue. Buying one is a purely commercial transaction, no different from ordering any custom rubber stamp.
Using that stamp on a notarial certificate without being a commissioned notary is another matter entirely, and it’s where real legal exposure begins.
- Owning a device never confers legal authority to notarise anything
- Only someone appointed and currently commissioned in that jurisdiction may lawfully perform notarial acts
- Confusion between US “notary public” and the civil-law “notario publico” has fuelled real fraud cases, which is why the American Bar Association urges verifying anyone’s authority before trusting their notarial acts
- Losing custody of a registered stamp, or letting an unauthorised person use it, can expose the commissioned notary to serious professional and legal consequences
Publisher expertise: stamp design and lawful use
Some suppliers manufacture and customise rubber stamps, including professional-grade devices, providing insight into what makes an impression legible and durable over years of use. Clean, high-resolution artwork and quality ink, such as the Trodat Professional Line, keep text sharp even after thousands of impressions.
None of that changes one fact: buying a well-made stamp doesn’t make anyone a notary. Legal authority comes from commissioning by the relevant regulator, never from the hardware itself.
A publisher’s view on respecting the mark
The stamp itself is only half the story. Good design keeps text legible for years, but the authority behind it comes from a genuine commission, not the rubber. Anyone relying on a notarised document should always verify the person, not just admire the impression.

FAQ
What is the purpose of a notary stamp?
A notary stamp visually confirms that a commissioned notary carried out a notarial act, such as witnessing a signature or verifying identity. It works alongside a written certificate, and in the US, certain sealed documents bearing it become self-authenticating under federal evidence rules.
Can you just buy a notary stamp?
Yes, stamp devices are sold openly by suppliers such as Stamp Design 4U, but purchasing one grants no legal authority to notarise documents. Only a person currently commissioned by the relevant regulator, such as the Master of the Faculties in England and Wales, may lawfully perform notarial acts.
How much does a notary cost in the UK?
Notary fees vary by firm and by the complexity of the document, and no fixed national rate exists. Current pricing for a notarial service is best confirmed directly with a notary registered on the Master of the Faculties register.
Who qualifies as a notary in the UK?
Only someone appointed and regulated by the Master of the Faculties may use the protected title “notary public” in England and Wales. The role is distinct from being a solicitor, though some professionals hold both qualifications.
