Notary seal and stamp requirements by state: size, ink color, and embosser rules
What your notary stamp must contain, state by state: the near-universal elements (name, commission number, expiration), shape and size limits, black-ink mandates, the no-seal states, and when an embosser is required or pointless — with buy-once-correctly ordering rules.
Nearly every state prescribes exactly what your notary stamp must contain — typically your name as commissioned, the words "Notary Public," your state, and in most states a commission number and expiration date — and many add rules about shape, maximum size, ink color, and whether an embosser counts as an official seal. The practical consequences are simple: never order a stamp before your commission certificate arrives, buy from a vendor that builds to your state's published specification, and proofread the imprint against the certificate so you only buy once. Every requirement on this page is as of publication and states do amend their seal statutes — Illinois and Pennsylvania both did in the past decade — so confirm the current specification with your commissioning authority before ordering.

The common core, before the quirks
| Element | How common | Notes |
|---|---|---|
| Name exactly as commissioned | Effectively universal | Middle initial included if your commission has one |
| "Notary Public" | Effectively universal | Some states prescribe fuller phrases |
| State name | Effectively universal | Often as "State of ___" in the required wording |
| Commission/ID number | Most states | A few states omit it |
| Commission expiration date | Most states | The element that makes stamps disposable at renewal |
| County | Some states | E.g., California and Pennsylvania include it |
| State seal, star, or coat of arms | A handful | California, Texas, and Ohio are examples |
If your state's spec were only this table, buying would be easy. The quirks below are where reorders come from.

The seven states we map, at a glance
These summaries track our state guides; treat them as orientation, not the statute, and verify before you order.
| State | Shape and size | Required imprint (summary) | Notable rule |
|---|---|---|---|
| California | Rectangle up to 1" x 2.5" (or circle up to 2") with a serrated or milled border | State seal, "Notary Public," name, county, commission number, expiration, vendor ID | Must be photographically reproducible; vendors require proof of commission |
| Texas | Rectangular or circular | Name, "Notary Public, State of Texas," expiration, ID number, five-pointed star | Star element is mandatory; stamp is the practical standard |
| Florida | Rectangular rubber stamp | "Notary Public - State of Florida," name, commission number, expiration | Black ink required, photographically reproducible |
| New York | No seal required | Beneath your signature: name, "Notary Public State of New York," county of qualification, expiration | An information stamp is optional but nearly universal in practice |
| Pennsylvania | Rectangle up to 1" x 3.5" with a border | "Commonwealth of Pennsylvania - Notary Seal," name and "Notary Public," county, commission number, expiration | Spec dates to the RULONA overhaul; old-format seals died at renewal |
| Illinois | Rubber stamp | Name, "Official Seal," "Notary Public, State of Illinois," expiration | Spec updated in the 2023 overhaul — confirm current wording before ordering |
| Ohio | Circular, traditionally about 1" | Ohio coat of arms, "Notary Public" or words of like import, name on or near the seal | Circular-with-coat-of-arms is the distinctive Ohio requirement |
Rectangular vs round, and why size limits exist
Most states either mandate or default to a rectangular ink stamp, because rectangles fit the signature block real estate on recorded documents. A minority use circles (Ohio) or allow both (California, Texas). The size caps — California's 1" x 2.5", Pennsylvania's 1" x 3.5" — exist for the same reason as the shape conventions: county recorders image millions of documents, and a seal that overruns margins or overlaps text gets documents rejected. Practical rules that follow: stamp only in clear space, never over wording or signatures; re-stamp in a clean spot if the first impression smears (never overstamp); and if the document has no room, attach a loose certificate rather than improvising.
Ink color: what's mandated vs what's smart
A number of states mandate ink color — Florida and Oregon, for example, require black — while many others require only that the imprint be photographically reproducible and legible. Where your state is silent, black is the professional default: it photocopies and scans cleanly, and reproducibility is the actual point of every ink rule. Blue can help distinguish originals from copies but scans lighter; novelty colors are a rejection risk at recording desks even where technically legal. Check your state's rule once, then buy the boring color.
Embosser: required, permitted, or pointless
The crimping embosser is the most misunderstood purchase in notary supplies, so here is the honest hierarchy as of publication:
- Required or specifically provided for: a small number of states build the embossed seal into their law or allow it as the official seal — often with the caveat that a raised impression must be inked or darkened to photocopy, since a bare crimp is invisible to a scanner.
- Permitted as a supplement: the majority position. California, for instance, allows an embosser in addition to the required ink stamp. Used this way it is a legitimate anti-fraud measure — a raised impression is hard to photocopy convincingly — and some notaries like it for wills, powers of attorney, and documents headed to receiving parties abroad who expect a raised seal.
- Pointless: if your state requires a reproducible ink imprint and you have no specific supplemental use, the embosser is $20-$40 of drawer furniture. Recorders reject documents whose only seal cannot be imaged.
Buy the ink stamp your state prescribes first; add an embosser only for a reason you can name.
The no-seal states
A handful of states require no seal at all — New York, Michigan, and Louisiana among them, as of publication. In these states you must still provide specified information near your signature (in New York: name, "Notary Public State of New York," county of qualification, and expiration), which is why nearly every working notary there carries an information stamp anyway: writing four lines by hand at a closing table gets old in one appointment. No-seal does not mean no-rules — it means the rules attach to the written details instead of a device.
Buying once, correctly
- Wait for the certificate. Your stamp must mirror the commission: exact name, number, dates. Vendors build from the certificate, and some states require the vendor to see it (California authorizes seal manufacturers this way).
- Use a state-spec vendor. Suppliers that build state-compliant stamps — Notary Rotary among them — encode the shape, border, and element rules so you don't have to; your job is proofreading, not typesetting.
- Proofread character by character. Name spelling, number, expiration. A wrong digit is a reorder; a wrong name can invalidate acts.
- Test on paper before the first appointment. Even, complete, legible impression; adjust ink before it matters.
- Guard it like the credential it is. Most states require reporting a lost or stolen seal, and a stray stamp is an identity-fraud kit. It lives in your bag or a locked drawer, and nobody borrows it.
When your stamp must change
Your stamp dies with your commission: the expiration date makes it single-term equipment, and recommissioning means a new stamp (sometimes a new number too) — which is why buying consumables in bulk is a losing trade. Replace it early for name changes (most states require updating your commission first), damage that degrades the impression, county changes where the county appears in the imprint, and statutory overhauls that change the required format, as Pennsylvania's RULONA transition and Illinois's 2023 rewrite both did. When in doubt, the sequence is always the same: commissioning authority first, vendor second, stamp last.
