Wyoming requires a round professional engineer seal made of two rings: 1-3/4 inches across on the outside and 1-1/4 inches across on the inside. In the band between the rings, your title phrase runs along the top and Wyoming along the bottom; inside the inner ring go the word Date, your license number and your name. You sign and date across the impression. Below: wording, devices, electronic seals and ordering.

| Size | Outer ring 1-3/4 inches in diameter, inner ring 1-1/4 inches in diameter. | Wyoming Board Rules ch. 5 § 1(a) |

Does Wyoming require a professional engineer to seal work?
Yes. Anything filed or recorded under the cited statutes carries the seal, and the statute pairs it with a signature and a date rather than letting the impression stand alone. The duty sits in statute, and the design of the device sits in the board rules.
That split is worth holding onto when you order. The statute tells you when to seal; Chapter 5 Section 1(a) tells the stamp maker what the die has to look like. A broader walk through both is in our guide to the Wyoming engineer seal guidelines.
What must appear on a Wyoming PE seal?
Five elements, and their positions are set as firmly as their wording. Three sit inside the inner circle and two sit in the band between the two circles.
- Your name, which sits in the inner circle
- Your license number, centered in that same inner circle
- The word Date, also in the inner circle
- In the upper annular space, whichever phrase applies to you: Professional Engineer, Professional Land Surveyor, or the combined Professional Engineer & Land Surveyor
- Wyoming, inscribed at the bottom of the annular space
The word Date is a fixed element of the die. It is not a date, and it is not a blank to be filled at the die stage. How those five pieces sit together is worked through in our notes on Wyoming engineering seal design.
Which title phrase applies to me?
One of three, and it goes in the upper band. A professional engineer takes Professional Engineer, a professional land surveyor takes Professional Land Surveyor, and someone holding both takes Professional Engineer & Land Surveyor.
Pick it from the credential you actually hold at the time the die is cut. A dual holder who orders the single title phrase has a die that understates the license, and a single license holder who orders the combined phrase has one that overstates it.
What size and shape is a Wyoming engineer seal?
Round, made of two concentric rings, 1-3/4 inches in diameter outside and 1-1/4 inches inside. The rule publishes these as set figures, not as a range you can work within.
The geometry is what makes the layout work. The gap between the two rings is a quarter inch on each side, and that band has to hold the title phrase above and Wyoming below at a size that still reads after a document is copied.
Which devices may I use in Wyoming?
The options are a computer generated seal, an embossing seal or an inked rubber stamp. The rule says the authorized device "is of the crimp type and/or rubber stamp facsimile", wording broad enough to cover the crimping embosser and the inked stamp.
Chapter 5 Section 1(c) separately allows a seal produced electronically, so long as the licensee's signature and the date accompany it and the generated image follows the design set out in subsection (a). Our range of Wyoming PE embossers and stamps covers the two physical formats.
Where do the signature and date go?
Over the seal. Wyoming requires signing through the stamp, so the impression goes down first and your signature and the date are laid across it rather than beside it.
That has a direct bearing on which device you buy. An impression you sign over has to stay legible under a pen line, which is one reason the inner ring is sized the way it is. The same requirement is what makes a faint or overloaded imprint a problem in practice.
Is an electronic seal allowed in Wyoming?
Yes. The rules permit one and do not name any vendor or product, setting instead a four part functional standard that the arrangement has to meet.
The design does not change when the seal goes electronic. The generated image follows the same layout as the physical die, and the licensee's signature and the date still accompany it.
What has to be sealed?
Everything filed or recorded under the statutes cited above. The trigger is the filing or recording, not the size of the job or the type of client.
Work that stays in house and is never filed does not pull the same duty from those provisions. Once a document goes to a filing or recording office, the seal, the signature and the date travel with it.
Can I keep using my seal if the license lapses?
The seal rules read here do not address it. Renewal and lapse are handled by statute rather than by the design rule, so the answer is not found in the chapter that governs the die.
The practical position is unchanged: the die carries your license number, and that number is what a reviewer checks against the register. Keep the credential current and the question does not arise.
What should I send when ordering a Wyoming seal?
Four items. Your name as it should read inside the inner circle, your license number, which of the three title phrases applies, and the format you want, whether that is an embosser, a rubber stamp or both.
Send the exact characters rather than a description, since we set what you send. If your name runs long, tell us so before the die is cut, because the inner circle is a fixed 1-1/4 inches and the number has to stay centered within it alongside your name and the word Date. Our page on the Wyoming professional engineer stamp walks through the same choices.
How do I check the impression before I use it?
Take one impression on plain white paper and measure it. The outer ring should come to 1-3/4 inches across and the inner ring to 1-1/4 inches across.
Next, check the content. Look for the title phrase in the upper band with Wyoming running along the bottom, and for your name, the centered license number and the word Date in the inner circle. Finally, sign over the impression as you would on an actual sheet and make sure each element is still legible beneath the pen line, because that is the way the seal will be seen.
Frequently asked questions
Is the 1-3/4 inch outer ring a maximum or an exact figure?
It is the figure the rule publishes for the outer circle, paired with 1-1/4 inches for the inner circle. Order to those two numbers rather than to a nearby stock size, since the geometry of the band between them depends on both.
Does the word Date mean the die should show a date?
No. Date is a literal element of the design and sits inside the inner circle as a word. The actual date is written when you sign, as part of the signature and date that go over the impression.
Do I need a separate seal for land surveying work?
Not if you hold both credentials, because the rule provides a combined phrase, Professional Engineer & Land Surveyor, for the upper band. A single seal carrying that phrase covers the holder of both.
Does an electronically generated seal need a different layout?
No. It follows the design in subsection (a), the same one the physical die follows, and it is used with the licensee's signature and date.
Does the license number have to be inside the inner circle?
Yes, and centered there. The rule places the number in the inner circle alongside your name and the word Date, not in the band with the title phrase.
Is a self inking stamp acceptable, or does it have to be a hand stamp?
The rule speaks to the crimp type and the rubber stamp facsimile rather than to the mounting. What matters is that the imprint matches the published design and stays readable once you sign across it.
Have your license number and title phrase to hand, then order from our Wyoming engineer stamps and seals range and we will set the die to the dimensions above.
