The Colorado notary seal, often called the “notary stamp” or “official notary seal,” is the tool a Colorado notary public uses when performing notarial duties. It’s one of the essential supplies you need to start your notary business, alongside your journal.
Each state sets its own requirements for notary seals, and they vary. The requirements below cover Colorado specifically. All of this is covered in detail in our Colorado Notary Training Course.
Two Types of Notary Seals
Colorado transitioned to new stamp requirements on August 8, 2012. The old-style stamps were only permitted for commissions active before that date and should all be out of use by now. Only the current requirements are covered below.
Embossing seals are not allowed in Colorado. Do not buy a seal embosser. Inked rubber stamps are required because they’re photographically reproducible. Embossed impressions don’t copy or scan well.
Requirements for Colorado Notary Stamps
Shape
The official stamp must be a rectangular inked rubber stamp with a rectangular outline or border. The law does not specify a particular size. Round stamp impressions are not permitted.
Ink color
Black ink is the most legible and photographically reproducible, making it the safest choice. Blue ink is also acceptable and some notaries prefer it because it stands out on documents printed in black. Either way, keep refill ink on hand.
Required information
Inside the rectangular border, the stamp must contain:
- Your legal name (as it appears on your commission certificate)
- The words “NOTARY PUBLIC”
- The words “STATE OF COLORADO”
- Your commission number
- Your commission expiration date
Example:
What’s not allowed
The stamp must not contain anything beyond the five required elements. No decorative symbols, no icons, no cute graphics. The Colorado state seal is also prohibited on notary stamps. This differs from states like California, which require it.
Where to Place Your Stamp
Stamp clearly in a location directly under or near your official signature. The stamp must not be placed over signatures, and you should avoid stamping over document text. If there’s no room on the document for your stamp, attach a loose notarial certificate and stamp that instead. Keep blank certificates on hand for this situation.
How to Get a Notary Stamp
The Secretary of State does not provide notary stamps or journals. You purchase these from retailers that specialize in Colorado notary supplies. notarystyle.com carries Colorado-compliant stamps with the correct layout and required information. Most vendors will ask for your commission number and expiration date to customize the stamp. Have that information ready after your application gets approved.
Frequently Asked Questions
Can I use an embossing seal in Colorado?
No. Colorado requires an inked rubber stamp. Embossing seals are not acceptable because the raised impressions don’t reproduce well in copies or scans.
Does Colorado require the state seal on my stamp?
No. Unlike California and some other states, Colorado prohibits the state seal from appearing on your notary stamp. Only the five required elements listed above.
What if my name changes during my commission?
You need a new stamp that reflects your current legal name. Contact the Secretary of State to update your commission information, then order a replacement stamp.
Do I need to replace my stamp when I renew?
Yes, if your commission number or expiration date changes (it will). You’ll need a new stamp with the updated information for your new commission term.
