How Notary Stamp Requirements Differ Between States

April 16, 2025 / Written by Nate Bortz

The fundamental role of a notary public is to act as a last line of defense against legal document fraud. This is achieved through different notarial acts such as identification verification and signature witnessing.

When a commissioned notary confirms the authenticity of a document and its signer, they notarize it using an official seal. This seal serves as proof that the document has been properly notarized and holds legal validity.

Despite the importance of a notary’s seal, there are many different state laws and statutes that govern them. With no broad certification standards in place, it’s up to the applicant to ensure their seal meets state-specific guidelines.

In this article, we'll describe the stamping requirements for each state and explain where to obtain a state-compliant stamp.

Looking for even more stamp-related information? We’ve written guides that explain the different types of stamps, how to dispose of expired ones and what to do if a stamp is lost or stolen.

Where to Get Your Stamp

States only provide commissions, not stamps or any other necessary supplies. It's up to the individual to find what they need for their commission.

Notaries.com is an authorized notary supply marketplace. We offer stamps that meet all state requirements and include instructions for cleaning and re-inking. All orders are processed quickly, and various shipping methods are used to ensure applicants receive their supplies when needed.

Notary Stamp Requirements by State

While state regulations vary, most states mandate that seals must include the notary’s name as it appears on their commission.

The other state-specific requirements, in addition to this, are listed below.
