Illinois Professional Engineer Stamps with a licensed structural engineer seal embossed on white paper, framed by flowers on a pink background, highlighting the PE Embossers Illinois design.

If you are working as a professional engineer in the state of Illinois, then you are required to have an embossed seal or stamp that conforms to the rules of the licensing board in the state. In Illinois, the regulations are considerably more relaxed when it comes to the shape and design of the stamp or embosser than they are in many other states, but there are still things you’ll need to know in order to be compliant.

About Illinois Professional Embossers and Stamps

Some states require the use of an embosser whether or not you use a stamp. Some states permit CAD stamps while others don’t. In some states, the dimensions of the seal or stamp are etched in stone. In Illinois, you have a lot of flexibility.

In Illinois, you can use an embossing seal or a rubber stamp, and the size or shape are up to you. The usual shape is circular, and the size is usually about 1.6 inches in diameter, but this isn’t mandated by law. Illinois professional engineer embossers or stamps can be any size

or shape, as long as they’re reproducible, and contain your name and license number and the phrase “Licensed Professional Engineer of Illinois.”

The embosser or stamp can, in short, be any shape or size. You can even use an electronic seal, generated by your computer. When it comes to your seal or stamp, the main requirement is simply that you have to have one.

Your Responsibilities

Don’t think that just because you have a lot of leeway when it comes to the design of your seal or stamp your responsibilities will be any less than they are in any other state. You are responsible for that seal and what it represents. Whether you are using Illinois professional engineer embossers, rubber stamps, computer generated signatures, or any other method approved by the state of Illinois, doing so means that you are stating that the work submitted has been either prepared by you, or under your direct personal supervision, and that you have prepared that work in accordance with accepted engineering standards. It further warrants that the work has been both prepared and done using accepted due diligence.

You may not affix your seal to anything that violates accepted standards, and you may not affix it to any documents if doing so conceals the true identity of the person who prepared or supervised the work. If you do, you can be held liable for any damage that may result

The Importance of Securing Your Seal

What happens if work is submitted under your seal, and you didn’t actually sign and seal the work yourself? As we’ve stated, you could be liable for any harm that results. However, if your seal has been stolen, or misused by someone you thought you could trust, you won’t be held liable provided that you immediately report the loss, theft or misuse of your seal.

Of course to avoid having such a thing happen, you should keep your seal in a secure location and make sure that you’re the only person who has access to it. And if something does go wrong, report it to the Board immediately.

Frequently Asked Questions

What information must be included on an Illinois Professional Engineer stamp or embosser?

An Illinois Professional Engineer stamp or embosser should include your name, your Illinois PE license number, and the wording “Licensed Professional Engineer of Illinois.” The state allows flexibility in the size, shape, and design, as long as the seal is reproducible and contains the required information.

Does Illinois require a specific size or shape for a PE seal?

No, Illinois does not require a specific size or shape for a PE embosser or stamp. While a circular seal around 1.6 inches is common, you can choose a size or shape that works best for you, as long as it remains compliant and legible.

Can I use an electronic Illinois PE seal instead of a traditional embosser?

Yes, Illinois allows an electronic seal generated by computer, as well as a rubber stamp or embossed seal. The key requirement is that the seal is usable on your documents and contains the required identifying information.

What is my responsibility when I apply my Illinois PE stamp or seal?

When you affix your seal, you are certifying that the work was prepared by you or under your direct personal supervision and that it follows accepted engineering standards. You should never seal work that does not meet professional standards or that hides the identity of the person who prepared the work.

What should I do if my Illinois Professional Engineer seal is lost or stolen?

If your seal is lost, stolen, or misused, report it to the Illinois Board immediately. Prompt reporting is important because it can help protect you from liability if someone else uses your seal without permission.

Where can I buy Illinois Professional Engineer embossers and stamps that meet state requirements?

You can find Illinois PE embossers and stamps from suppliers that specialize in professional sealing products, such as Acorn Sales Company Incorporated. Look for options that clearly include your name, license number, and the required Illinois wording so your seal is ready for compliant use on plans and reports.
