A North Carolina professional engineer seal must carry three things: the name you hold your license under, the number of that license, and the legend professional engineer. Any common type of sealing device is lawful, and electronic sealing is permitted. You may reproduce the seal image, but never your signature. This page covers the seal face, devices, signing, sealed documents, electronic seals, expiration and ordering.

North Carolina is one row in our professional engineer seal requirements by state table, which sets each jurisdiction's rule side by side.
What does a North Carolina PE seal have to show?
N.C. Gen. Stat. § 89C-16(c) lists three: the legend professional engineer, your name matching your license, and the number of that license. Those are the seal elements the statute itself names.
- Name: the form you are licensed under, not a shortened or informal version.
- License number: matching your license digit for digit.
- Legend: professional engineer.
The statute's list covers content, not measurements, so the three items can be checked directly against your license. For the buying side, see our notes on getting your North Carolina PE stamp.
Which sealing devices can a North Carolina engineer use?
Any common form of sealing device is lawful under 21 N.C. Admin. Code 56.1103(a)(2), and electronic sealing is permitted on its own terms. North Carolina does not restrict you to a single device type for applying the seal.
Pick the device by how your documents travel. Because the rule lets the seal be reproduced, a seal image that prints as part of a plan set is consistent with it, while the signature still has to be handled on its own. For help comparing options, see choosing a North Carolina professional engineer stamp.
Is there a required seal size in North Carolina?
No size or outline is stated in the cited rules. The North Carolina PE seal is manufactured at 1-3/4 inches, which is a production size and not a legal requirement a reviewer can hold you to.
With the law silent on dimensions, the test that matters is content: your name as licensed, your number and the legend, all readable on the finished document.
Can the seal or the signature be reproduced in North Carolina?
The seal can; the signature cannot. Under the sealing rule, a reproduced seal image is acceptable, but your signature has to be an actual signature rather than a copy of one.
That split shapes the workflow. You can print the seal on every sheet of a set, but the signature step cannot be automated by pasting a scanned signature or pressing a signature stamp. More on the process is in how the PE stamp is used in North Carolina.
Which documents must carry a North Carolina PE seal?
Final plans, drawings, specifications and reports all take the seal, and the sealing rule extends the list to calculations and letter reports. Sealing covers the written work as well as the drawings.
Calculations and letter reports are easy to treat as working papers. Under the rule they are sealed documents, so they get the seal just as the drawing set does.
- Final plans and drawings
- Specifications
- Reports, including letter reports
- Calculations
How does North Carolina handle electronic seals?
Electronic sealing is permitted. Instead of naming a vendor or technology, 21 N.C. Admin. Code 56.1103(d), (e) and (f) set out four properties every electronic seal must have.
Because the rule names properties rather than products, no particular software brand is required. This page does not list the four properties, since their wording was not part of the material checked here. Read them in the rule itself before you settle on a signing product, because any tool you use has to meet all four.
What happens if your North Carolina certificate of licensure expires?
You have to stop sealing. Under N.C. Gen. Stat. § 89C-16(c), affixing your seal after your certificate of licensure expires is unlawful, and § 89C-17 is cited with it for this point.
Plan renewals ahead of submittal dates so no sealed set goes out after expiration. For the licensing side, see our notes on North Carolina engineering certification.
What should you supply when ordering a North Carolina PE seal?
Your name exactly as licensed and your license number. The legend professional engineer comes from the statute, and the North Carolina PE seal is manufactured at 1-3/4 inches, so those two details need no input from you.
- Name: as licensed.
- License number: copied from your license.
- Device: any common form, since the rule does not limit you to one.

How do you check a North Carolina seal impression before use?
Compare the impression with your license. The name should read as licensed, the license number should match digit for digit, and the legend should say professional engineer. Then confirm your signing process uses your actual signature, not a copy of it.
Keep a clean sample impression on file. It gives you a reference for later impressions and for any printed seal image you place on drawings.
If you also hold a North Carolina geologist license, the North Carolina geologist seal rules set out what that seal must carry.
Frequently asked questions
Can I use a signature stamp with my North Carolina seal?
No. The rule bars reproducing the signature, so a signature stamp or a pasted image of your signature does not meet it.
Can my seal be printed from a title block file?
The rule allows the seal to be reproduced, so a printed seal image fits it. Your signature on that sheet still cannot be a reproduction.
If my renewal is in the mail, can I keep sealing after the expiration date?
No. The statute makes affixing the seal unlawful once the certificate of licensure has expired, whatever the status of a pending renewal.
Does the legend have to say professional engineer?
Yes. The statute names professional engineer as the legend, so that is the wording to use.
Which board oversees North Carolina PE seals?
North Carolina professional engineers are regulated by the Board of Examiners for Engineers and Surveyors.
