Ohio Notary Seal Requirements

What Ohio Law Requires on Your Seal

Under R.C. 147.04, every commissioned Ohio notary must have an official seal that meets specific physical and textual requirements. Using a seal that doesn't comply — wrong size, missing elements, illegible text — can result in rejected documents and disciplinary complaints.

Here's what the statute requires and what your options are.

The Mandatory Specifications

Your Ohio notary seal must include all of the following, except that your commissioned name may instead be printed, typewritten, or stamped in legible letters near your signature on each document:

• Shape: A circle with a diameter between 3/4 inch and 1 inch
• Center image: The Coat of Arms of the State of Ohio
• Border text: The words "Notary Public" or "Notarial Seal" (or words to that effect) and "State of Ohio"; your commissioned name may appear on the seal or near your signature as described above

If you place your name on the seal, it must match exactly the name on your commission certificate from the Secretary of State. If there's a discrepancy — a middle initial on one but not the other, a hyphenated surname that doesn't match — the seal is technically non-compliant and any notarizations performed with it could be challenged.

Rubber Stamp vs. Embosser

Ohio accepts both formats:

Rubber ink stamp: Produces a visible impression in black or blue ink. This is the most common choice because it photographs and scans clearly, which matters for electronic document storage and county recording submissions.

Physical embosser: Creates a raised impression in the paper. Some notaries use an embosser alongside a rubber stamp for additional security, since a raised seal is harder to reproduce on photocopies. However, an embosser impression alone can be difficult to read on scanned copies, and some county recorders have rejected documents where the seal is embossed but not stamped.

For most working notaries — especially those in real estate, title, or legal support — a rubber ink stamp is the practical choice. If you also want an embosser, use both: stamp for visibility, emboss for tamper resistance.

When to Order (and When Not To)

This is a common and costly mistake: ordering your seal before your commission is approved.

The Secretary of State reviews your application and may reject it if your name doesn't match perfectly across your BCI report, education certificate, and application. If you've already ordered a custom seal with a name that doesn't match your final commission, you'll need to re-order.

Wait until you receive your commission certificate by email. Then order your seal with the exact name as it appears on that certificate.

Where to Buy

Authorized notary stamp vendors are available online and through many of the approved education providers. A basic rubber stamp runs $15–$30. An embosser adds another $20–$40.

When ordering, you'll typically provide:

• Your full commissioned name (exactly as it appears on your certificate)
• Your commission number (if the vendor requests it)
• Your commission expiration date

Some vendors offer "starter kits" that bundle a stamp, embosser, and journal together. These are convenient but not always the best value — check what's included against what you actually need before paying a premium for bundled items.

What About a Journal?

Ohio does not legally require a journal for traditional paper-based notarizations. However, the Secretary of State strongly recommends maintaining one as protection against allegations of fraud, negligence, or misconduct.

If you plan to pursue Remote Online Notarization, a tamper-evident electronic journal is mandatory — along with a 10-year retention requirement for both journal entries and audio-video recordings of each session.

For traditional notarizations, a simple bound journal with sequential entries (date, signer name, document type, notarial act performed) is sufficient. Expect to pay $10–$25 for a quality notary journal.
