A Utah geologist seal must be a circle at least 1-1/2 inches in diameter showing "Licensed Professional Geologist", "State of Utah", your license number and your name as licensed. It may be inked, embossed or produced electronically. Your signature and the date go across its face, and every original set is sealed on at least its cover or title sheet. This page covers face, size, devices, signing, documents and ordering.

What goes on the face of a Utah geologist seal?
Four items inside a circle: the title Licensed Professional Geologist, the phrase State of Utah, your name as it appears on your license, and your license number. Utah Admin. Code R156-76-601(1)(b) lists them along with the circular form.
The title is the line to copy with care. Utah's wording opens with "Licensed", so a die reading Registered Professional Geologist, or Professional Geologist alone, does not reproduce the prescribed title even though every word on it may be accurate about you.
The rule lists nothing beyond these four items and the circle. Our article on the Utah geologist stamp adds background on the device itself.
Where do the signature and date go?
Across the face of the seal. Utah Admin. Code R156-76-601(1)(c), (d) places both the signature and the date over the impression itself, not beside it or below it on the sheet.
That affects the artwork. Keep the lettering to the outer band and leave the center open enough for a signature and a date to cross it without making the name or number unreadable.
Which documents need the seal, and where in the set?
Final geologic documents prepared by you or under your supervision. Under Utah Admin. Code R156-76-601(1)(d), every original set has to carry an original imprint, your original signature and the date, and the cover or title sheet is the minimum place for them.
Read "at a minimum" literally: the cover or title sheet is the floor, and nothing in the provision stops you sealing more. Work produced by staff under your supervision is covered too, so it goes out under your seal. For the wider case, see why a geologist seal matters in Utah.
How large must the seal be?
At least 1-1/2 inches in diameter, and round. Utah Admin. Code R156-76-601(1)(a) sets a minimum only, so the rule is met by any circular seal from that size upward.
Because the signature and date cross the face, a little extra diameter can help. A larger circle gives more open space in the center, which keeps the name and number legible under the ink of a signature.
Which devices are allowed?
Three: a wet stamp, an embossed seal, or a seal produced electronically. Utah Admin. Code R156-76-601(1) permits all three, and it expressly makes an embosser lawful for the required seal.
The practical choice depends on the set. An embossed impression is lawful, but the signature and date still have to cross its face, and a raised impression without ink tends to fade on a photocopy, so an inked or electronic version suits sets that will be copied. See also our guide to the professional geologist stamp for Utah.
Can the seal be produced electronically?
Yes. Utah Admin. Code R156-76-601(1) lists electronic production as a permitted form of the seal, next to the wet stamp and the embossed seal, and it ranks none of the three above another.
The other parts of the seal rule are not relaxed for the electronic form. It still needs the four items, the circular shape, the 1-1/2 inch minimum, and a signature and date across its face.
What does the seal rule say about renewal or a lapsed license?
Nothing. The seal rule is silent on renewal, expiration and lapse, per Utah Admin. Code R156-76 (seal rule silent). It covers the design and use of the seal, not the status of the license behind it.
That silence is limited to the seal rule, and this page does not reach beyond it. For the licensing side, see our article on obtaining Utah geologist certification.
What should a seal order include?
The two fixed lines, your licensed name and number, a diameter of at least 1-1/2 inches, and the device you want. The maker works only from what you send, so copy each line from your license.
- Name, as it appears on your license
- License number
- State of Utah
- Licensed Professional Geologist
- Round, 1-1/2 inches or larger
- Device: wet stamp, embosser, electronic file, or a combination
Our note on investing in a Utah geologist seal is a useful companion to the list.
How do you proof the seal before use?
Make a test impression, measure it against the 1-1/2 inch minimum, and read the four items against your license. Then sign and date across the face, as you would on a real cover sheet.
If the signature buries the name or number, the center is too crowded; a larger diameter or lighter lettering fixes that. For an embossed seal, check the test under raking light so the raised letters read clearly.

Frequently asked questions
Is there a maximum size for a Utah geologist seal?
No maximum is stated. Utah Admin. Code R156-76-601(1)(a) gives a minimum diameter only, so a larger circle meets the rule as long as it stays round and carries the four items.
Does work drafted by my staff go under my seal?
Yes, when you supervised it. The rule covers final geologic documents prepared by you or under your supervision, so supervised work is sealed, signed and dated by you.
Does the seal need an expiration date?
No. The four items in Utah Admin. Code R156-76-601(1)(b) do not include one, and the seal rule is silent on renewal. The only date involved is the one you write across the face when sealing.
Can an electronic seal go on a PDF report?
The rule permits an electronically produced seal, so an electronic form is available. It still has to carry the four items at no less than 1-1/2 inches, with your signature and date across the face.
If I seal only the cover sheet, is the set compliant?
As far as Utah Admin. Code R156-76-601(1)(d) goes, yes. In every original set, the rule's minimum is the cover or title sheet, which must carry the original imprint, original signature and date. Sealing further sheets is not required by that provision but is not ruled out.
When your license details are in hand, order from our Utah stamps and seals collection and copy each line exactly as your license shows it.
