If you’re a notary in the Show-Me State, you’ve probably come across missouri notary stamp law at some point. It can feel overwhelming at first, but understanding these rules is key to keeping your commission in good standing. Below, you’ll find clear insights into what the law expects from you, plus tips on choosing the best supplies for your notarial acts.
Discover your Missouri stamp rules
You are only allowed one notary stamp and one seal embosser per commission in Missouri. This specific regulation helps ensure each notary can track and control every impression they make. If you need a new stamp for a freshly issued commission, you must order one that reflects your updated expiration date.
Some basic rules to remember:
- Keep your stamp secure in a locked place.
- Use black ink that photocopies clearly.
- Never share your stamp—even briefly—with another person.

Make sense of seal elements
Missouri notary law calls for particular wording on your stamp. Here’s a quick overview:
| Required element | Description |
|---|---|
| Your name | Must match the name appearing on your commission |
| "Notary Public" | Identifies your official role |
| "State of Missouri" | Indicates your jurisdiction |
| Commission number | Unique identifier provided by the state |
| Commission expiration date | Must be current and legible |
You may use a non-inked seal embosser, too, but it cannot replace the official inked stamp. Instead, it can serve as an extra measure for added authenticity.
Follow essential usage guidelines
Missouri requires you to use your stamp on all notarial acts, so it’s vital that you apply it correctly and consistently. Skipping or misusing your stamp can lead to rejected documents. If your stamp leaves a smudged or unreadable impression, strike a line through it and stamp again closer to the original. Always test your stamp on a spare sheet of paper first to avoid damaging important documents.
Crucial reminders:
- Do not affix the stamp if the document lacks a clear notarial certificate.
- Never continue stamping documents once your commission expires.
- Properly dispose of an expired stamp to prevent misuse.
Stay updated on new laws
Missouri has made important strides with remote online notarization (RON). Since August 2020, you can notarize documents remotely, provided you meet registration and technology requirements. House Bill 754, signed on July 11, 2025, also allows electronic signatures on last wills and estate planning documents. This bill ensures that future emergencies, such as pandemic lockdowns, won’t prevent you from finalizing critical paperwork.

Frequently Asked Questions
How often do I need to reorder my stamp?
You’ll need a new stamp for each new commission term. Missouri law says your stamp must reflect the correct expiration date and commission information, so expect to replace it every time the state issues or renews your commission.
Can I use a different ink color?
Black is the required ink color for your notary stamp in Missouri. Other colors might look appealing, but they typically won’t meet the state’s photocopy requirement for official records.
Is a separate seal embosser required?
You are permitted to use a non-inked seal embosser in addition to your inked stamp, but it’s optional. The inked stamp is mandatory for recording and legal acceptance, while the embosser provides an extra touch of authenticity if you choose to use it.
What if my stamp impression is faulty?
If you make a partial or blurry impression, cross it out with a pen, then stamp again near the original. Always test your stamp on scrap paper before stamping official documents to avoid costly mistakes.
