A New Jersey professional engineer's seal must show the designation professional engineer, your license number and your name as licensed. Draft and incomplete sheets may carry your signature but never the seal, and their title block must say plainly that they are unsealed. Electronic seals are allowed under a rule that cites a federal cryptographic standard by name. This page covers wording, devices, drafts, signing, digital seals and renewal.

What must a New Jersey PE seal show?
Three items under N.J.A.C. 13:40-8.1(a): the designation professional engineer, your license number, and your name as licensed. Nothing else is listed as required, so the face of the seal stays short and specific.
Because the list is short, a proof check is quick: three lines, each compared against your license. Our notes on New Jersey engineer seal design have more on how the face is laid out.
Which device serves as the New Jersey seal?
Subsection (a) handles this in two steps: it names the device that serves as the seal, and it prohibits one stand-in for that device. The gap between those two points is where a lot of the advice on New Jersey seals goes astray.
Read N.J.A.C. 13:40-8.1(a) before you choose a device, and use the one it names as your seal. Our guide to using a New Jersey engineering embosser and our article on acquiring a professional engineer seal in New Jersey go further into the device side.
What size is a New Jersey engineer seal?
The cited rules state no size. New Jersey engineer seals are manufactured at 1-1/2 inches, which is a production standard and not a published rule, so treat that figure as a manufacturing choice rather than a legal requirement.
With no size in the rule text, the content of the seal and the device you use matter more than the diameter when you order.
Can you seal a draft or incomplete set in New Jersey?
No. Under N.J.A.C. 13:40-8.1(f), anything incomplete or still in draft may carry your signature but not your seal. The signature is optional at that stage; the seal has to wait.
This shapes how review sets leave your office. A set sent out for comment before it is finished can be signed if you choose, stays unsealed, and carries a label saying so.
How must an unsealed draft be labeled?
The title block has to identify the sheet prominently as not sealed. A faint note tucked into a corner does not meet a conspicuous standard, so make the wording easy to see.
Build the label into your draft title block template, so it appears on every review sheet without anyone having to remember it. Our overview of New Jersey PE stamp guidelines has more on day-to-day sealing practice.
What do the sources confirm about signing and dating?
Only part of the rule. The signature and date provisions tied to N.J.A.C. 13:40-8.1(f) were partially verified in the sources read for this page, and the unverified part is named rather than guessed at.
What is confirmed is that a draft may be signed without being sealed. Where the signature sits, what form it takes and which date appears are not stated on this page, because the verified text does not settle them.
Does New Jersey accept a digital seal?
Yes. N.J.A.C. 13:40-8.1A permits an electronic seal, and New Jersey stands out as one of a small number of states whose rule identifies a specific federal cryptographic standard for it.
That turns your choice of signing software into a compliance decision. Before you seal electronically, confirm that your signing tool meets the standard the rule names.
How often do New Jersey PE licenses renew?
Every two years. The two-year cycle comes from the board's renewal rules, cited in the table above. Those rules, as cited here, do not say what happens to sealing during a lapse, so this page states no rule on it.
Keep the renewal current so the question never arises. For the seal regulations in general, see our summary of New Jersey engineer seal regulations.
What should you send with a New Jersey seal order?
Your license number, your name as licensed, and your choice of device. The designation professional engineer is the same for every licensee, and the seal is produced at 1-1/2 inches.
Choose the device with subsection (a) in mind. Order the device the rule names as your seal, and treat anything else as an extra, never as the seal itself.
How do you check the impression before first use?
Stamp a test impression and check for three items: the words professional engineer, your license number, and your name exactly as it is shown on your license. Next, make sure the device under test is the device subsection (a) names.
If you also seal electronically, run a test file through your signing tool and confirm the signature validates before a client set depends on it.
Frequently asked questions
Does the name on my seal have to match my license exactly?
Yes. The rule calls for your name as licensed, so use the form on your license rather than a nickname or a shortened version.
Does the New Jersey seal have to be round?
The cited rules state no shape. They deal with what the seal says and which device serves as the seal, not with its outline.
Is a scanned image of my seal a digital seal?
Not under a rule that names a cryptographic standard. A scan is a picture and carries no cryptographic signature, so it cannot meet N.J.A.C. 13:40-8.1A by itself.
Can I use a 2-inch seal in New Jersey?
The cited rules set no size, so a 2-inch device does not conflict with them. The 1-1/2 inch figure is how New Jersey seals are produced, not a legal limit.
Which board writes the New Jersey seal rules?
That is the State Board of Professional Engineers and Land Surveyors, whose seal provisions are found in the N.J.A.C. 13:40 sections this page cites.
With your license details at hand, order your New Jersey professional engineer seal in the device subsection (a) names.
