Written by Acorn Sales Company, manufacturing stamps and seals since 1964 · Reviewed by Holly R, VP of Sales and Marketing at Acorn Sales, against the Wyoming Board of Professional Engineers and Professional Land Surveyors and Wyo. Stat. §§ 33-29-601, 33-29-801 on 21 September 2026 · Updated 21 September 2026
Wyoming makes you file an impression of the seal you bought with the board, and the board can reject it. Chapter 5 Section 1(h) of the board rules requires a new licensee, on notification that all license requirements are satisfied, to obtain and purchase a seal of the design stipulated in Section 1(a) and then submit on a board form an impression or stamp of that seal with an original signature superimposed over it. The rule then provides that the Board shall approve or disapprove any seal not meeting the exact specifications of Section 1(a) and shall require the licensee to obtain and pay for another seal meeting those specifications before sealing any work. The licensee pays twice, once for the rejected die and once for its replacement.
So the geometry is not advisory. The seal “consists of two concentric circles with the diameter of the outer circle being 1-3/4 inches and the diameter of the inner circle being 1-1/4 inches.” Those are exact values, not minimums. The band between them carries the title phrase above and Wyoming below; the inner circle carries your name, your license number and the word Date.
One failure mode is entirely avoidable. The board’s layout template uses the placeholders (NAME) and (NUMBER), and the rule says “The words and parentheses ‘(NUMBER)’, and ‘(NAME)’, should not appear on the seal.” A die cut straight from the template without substituting the real values is defective on its face.

Is a seal required in Wyoming?
Wyoming requires a seal Wyoming splits the duty between statute and rule and pins it to recording. Wyo. Stat. § 33-29-601(b) requires that whenever the professional seal is applied, the licensee's signature and the date also be included; subsection (c) requires the seal, signature, and date to be “placed on all final designs, specifications, maps, land surveys, reports, plats, drawings and plans filed or recorded pursuant to W.S. 33-29-801.” Section 33-29-801(a) then sweeps in every map, plat, plan, design, and other engineering or surveying document required to be filed or recorded in the state engineer's office, the office of state lands and investments, any county clerk's office, any city or town office, or any other office of public record in Wyoming, excepting filings with the oil and gas commission, and requires each to be made by or under the responsible charge of a licensee and to “be signed by and bear the seal of the professional engineer or professional land surveyor.” Board rules Chapter 5 Section 1(c) restates the requirement for original and non-original copies.
What must appear on the seal
- The applicable phrase in the upper annular space: Professional Engineer, Professional Land Surveyor, or Professional Engineer & Land Surveyor
- The inscription Wyoming at the bottom of the annular space
- Your name, inside the inner circle
- Your license number, centered in the inner circle
- The word Date, inside the inner circle
Wyoming is prescriptive and tells you what must not appear. The rule directs that the license number be centered in the inner area in the space occupied by the word NUMBER, that the size of the numbers not be larger than the word NAME, and that “The words and parentheses ‘(NUMBER)’, and ‘(NAME)’, should not appear on the seal.” Those parenthetical placeholders come straight off the board's layout template, and a die cut from the template without substituting the real values is a defective seal. Seals authorized before July 1, 2013 may continue in use under Chapter 5 Section 1(b), so an older die with different wording is not automatically invalid. There is no expiration date and no discipline line.
Size and shape
Two concentric circles: outer circle 1-3/4 inches diameter, inner circle 1-1/4 inches diameter. These are exact values, not minimums. The rule reads that the seal “consists of two concentric circles with the diameter of the outer circle being 1-3/4 inches and the diameter of the inner circle being 1-1/4 inches.” The band between the two circles carries the title phrase above and Wyoming below; the inner circle carries name, number, and the word Date.
Embosser, rubber stamp or digital
The rule names the crimp and the rubber stamp: the seal authorized by the Board for licensees “is of the crimp type and/or rubber stamp facsimile”. Electronically generated seals are separately allowed under Chapter 5 Section 1(c), provided they are accompanied by the licensee's signature and date and the generated seal complies with the design in subsection (a). The safe buy is a rubber or self-inking stamp at exactly 1-3/4 inches outside diameter, because that is the device the board will be matching your filed impression against, and because the imprint has to stay legible in its entirety.
Signing and dating
Wyoming requires signing through the stamp. Chapter 5 Section 1(c): “To be valid, any seal must be legible in its entirety and the signature of the Licensee and date of signing must be superimposed over the seal.” The date is the date of signing. Section 1(e) permits a digital signature that is unique to the licensee, capable of verification, under the licensee's sole responsibility and control, and linked to the document so that the signature is invalidated if any data changes. Section 1(f) permits a scanned image or other reproduction of an original signature in lieu of an original or digital signature if accompanied by the date of signature. On a multi-sheet document the title page or first page is sealed, signed, and dated by the licensee who supervised the work. Legible full size or reduced reproductions are acceptable as long as an original with signature, seal, and date stays in the licensee's possession.
The board inspects the stamp you sell, and can make the licensee buy another one
Wyoming is the state in this group where the supplier's work is formally reviewed. Board rules Chapter 5 Section 1(h) requires a new licensee, on notification that all license requirements are satisfied, to obtain a seal of the design stipulated in Section 1(a), to purchase it, and then to submit on a board form an impression or stamp of that seal with an original signature superimposed over it, for the Board's records.
What happens next is the part vendors underestimate. The rule provides that the Board shall approve or disapprove any seal not meeting the exact specifications of Section 1(a) and shall require the licensee to obtain and pay for another seal meeting those specifications before sealing any work. You pay twice, once for the rejected die and once for its replacement.
So the tolerances are not advisory. Outer circle 1-3/4 inches and inner circle 1-1/4 inches exactly; the title phrase in the upper band; Wyoming in the lower band; name, number, and the literal word Date inside the inner circle; the number centered and no larger than the word NAME; and no leftover (NAME) or (NUMBER) placeholders. A replacement or additional seal triggers the filing again, this time with a sworn statement of the purpose for the duplication, under the same subsection.
Which documents must be sealed
Everything filed or recorded under Wyo. Stat. § 33-29-801, which is the practical universe of Wyoming public-record engineering and surveying documents, plus the final designs, specifications, maps, land surveys, reports, plats, drawings, and plans listed in § 33-29-601(c). Carve-outs: filings with the oil and gas commission under its own rules are excluded by § 33-29-801(a), and § 33-29-801(e) lets the state engineer adopt rules providing exceptions to the sealing requirement for projects that because of size, nature, or location would not impede public safety. Chapter 5 Section 1(g) bars after-the-fact ratification by sealing work not performed by or under the licensee's responsible charge and supervision unless a thorough technical review is done.
Electronic and digital seals
No named vendor technology, but a real four-part functional standard. Under Chapter 5 Section 1(e) a digital signature must be unique to the licensee, capable of verification, under the licensee's sole responsibility and control, and linked to the document so that the signature is invalidated if any data in the document is changed; a digital signature using a process approved by the board is presumed to meet the criteria. Any hard copy printed from the transmitted electronic file must bear the facsimile of the signature and seal and confirm the file was not altered after the initial digital signing, and alterations void the signature facsimile. Separately, Section 1(d) invokes the Uniform Electronic Transactions Act, Wyo. Stat. §§ 40-21-101 through 40-21-119, to permit an electronic image of the seal, signature, and date in lieu of originals on electronic submittals to local, state, and federal agencies and between private entities.
Renewal, lapse and retirement
Wyo. Stat. § 33-29-601(e) prohibits a licensee from permitting the use of the seal by another, or from using the seal “when his license has expired, is inactive or has been revoked or suspended.” Subsection (f) bars an unlicensed individual from using a licensee's seal. Note that inactive status disqualifies the seal in Wyoming, not only expiration and discipline. The board rules provide for renewal, retired status, failure to timely renew, reactivation, relicensure, and reinstatement in Chapter 4. Not addressed: neither the statute nor Chapter 5 requires the seal to be destroyed or surrendered, and neither says whether a license number changes on relicensure or reinstatement.
Firm registration
Registration with the board, not a certificate of authorization, and no firm seal. Wyo. Stat. § 33-29-602(a) permits practice through a business entity provided the entity has registered with the board and submitted a description of the services to be practiced and a designation of the individual or individuals in responsible charge, with changes filed within thirty days. Board rules Chapter 5 Section 5 requires any business entity offering to practice to be registered with the Board and lists the information submitted on board forms. The document still carries only the individual's seal: § 33-29-602(a)(iii) requires that all final maps, plats, plans, designs, and other documents filed or recorded under § 33-29-801 “shall be dated and bear the signature and seal of a professional engineer or professional land surveyor in responsible charge of the work”. No firm registration number is required on the face of the document by statute or by Chapter 5.
What to check before you order
The geometry is exact: two concentric circles, 1-3/4 inch outer and 1-1/4 inch inner, the title phrase in the upper band, Wyoming in the lower band, and your name, license number, and the word Date inside the inner circle. Every template placeholder has to come off, so (NAME) and (NUMBER) must not survive onto the die, and the number stays no larger than the word NAME. You file an impression of the finished seal with the board for approval, and the board can disapprove it and leave you needing a replacement, so check the layout against Chapter 5 Section 1(a) before the die is cut. Crimp and rubber stamp are the named devices and electronic seals are allowed if they reproduce the same design; take the inked stamp as your primary. Leave room for a signature superimposed over the seal, since that is a validity condition, and note that Wyoming does not require anyone to verify your licensure.

Frequently asked questions
Do I need a PE seal in Wyoming?
Yes, and the duty is pinned to recording. Wyo. Stat. § 33-29-601(b) requires that whenever the seal is applied, the licensee’s signature and the date be included, and subsection (c) requires the seal, signature and date on “all final designs, specifications, maps, land surveys, reports, plats, drawings and plans filed or recorded pursuant to W.S. 33-29-801.” Section 33-29-801(a) sweeps in every map, plat, plan, design and other engineering or surveying document required to be filed or recorded in the state engineer’s office, the office of state lands and investments, any county clerk’s office, any city or town office, or any other office of public record in Wyoming, excepting oil and gas commission filings.
What size is a Wyoming PE seal?
Two concentric circles, the outer 1-3/4 inches in diameter and the inner 1-1/4 inches. Those are exact figures in Chapter 5 Section 1(a), not minimums, and the board compares your filed impression against them.
What has to be on a Wyoming seal?
Five things, per Chapter 5 Section 1(a): the applicable phrase in the upper annular space, which is Professional Engineer, Professional Land Surveyor, or Professional Engineer & Land Surveyor; the inscription Wyoming at the bottom of the annular space; your name inside the inner circle; your license number centered in the inner circle; and the word Date inside the inner circle. There is no expiration date and no discipline line.
Why does the board want an impression of my seal?
For its records, and to check the artwork. Chapter 5 Section 1(h) requires a new licensee to buy the seal and then submit an impression or stamp of it, with an original signature superimposed over it, on a board form. The board approves or disapproves any seal not meeting the exact specifications of Section 1(a) and requires the licensee to obtain and pay for another one before sealing any work. A replacement or additional seal triggers the filing again, this time with a sworn statement of the purpose for the duplication.
Where do the signature and date go on a Wyoming seal?
Over the top of it. Chapter 5 Section 1(c): “To be valid, any seal must be legible in its entirety and the signature of the Licensee and date of signing must be superimposed over the seal.” The date is the date of signing. On a multi-sheet document the title page or first page is sealed, signed and dated by the licensee who supervised the work. Legible full size or reduced reproductions are acceptable as long as an original with signature, seal and date stays in the licensee’s possession.
Crimp seal or rubber stamp in Wyoming?
Both are named. The rule says the seal authorized by the Board for licensees “is of the crimp type and/or rubber stamp facsimile,” and Chapter 5 Section 1(c) separately allows electronically generated seals provided they are accompanied by the licensee’s signature and date and the generated seal complies with the design in subsection (a). A rubber or self-inking stamp at exactly 1-3/4 inches outside diameter is the practical primary device, because the imprint has to stay legible in its entirety under a superimposed signature.
What does Wyoming require for a digital signature?
A four part functional standard. Under Chapter 5 Section 1(e) a digital signature must be unique to the licensee, capable of verification, under the licensee’s sole responsibility and control, and linked to the document so that the signature is invalidated if any data in the document is changed; a digital signature using a process approved by the board is presumed to meet the criteria. Any hard copy printed from the transmitted electronic file must bear the facsimile of the signature and seal and confirm the file was not altered after the initial digital signing, and alterations void the signature facsimile. Section 1(f) separately permits a scanned image or other reproduction of an original signature in lieu of an original or digital signature if accompanied by the date of signature.
Can I use an electronic image of my Wyoming seal on a submittal?
Yes. Chapter 5 Section 1(d) invokes the Uniform Electronic Transactions Act, Wyo. Stat. §§ 40-21-101 through 40-21-119, to permit an electronic image of the seal, signature and date in lieu of originals on electronic submittals to local, state and federal agencies and between private entities. No product or certificate authority is named.
Which Wyoming documents are exempt from sealing?
Two carve-outs. Filings with the oil and gas commission under its own rules are excluded by § 33-29-801(a), and § 33-29-801(e) lets the state engineer adopt rules providing exceptions for projects that because of size, nature or location would not impede public safety. Chapter 5 Section 1(g) separately bars after-the-fact ratification by sealing work not performed by or under the licensee’s responsible charge and supervision unless a thorough technical review is done.
My license went inactive. Can I still use my Wyoming seal?
No. Wyo. Stat. § 33-29-601(e) prohibits a licensee from permitting use of the seal by another, and from using the seal “when his license has expired, is inactive or has been revoked or suspended.” Inactive status disqualifies the seal in Wyoming, not just expiration and discipline. Subsection (f) bars an unlicensed individual from using a licensee’s seal. Renewal, retired status, failure to timely renew, reactivation, relicensure and reinstatement are handled in Chapter 4 of the board rules. Whether the seal must be destroyed or surrendered, and whether a license number changes on relicensure or reinstatement, is not addressed in the statute or in Chapter 5.
Does my firm register, and does its number go on the drawings?
The firm registers with the board and its number does not appear on the document. Wyo. Stat. § 33-29-602(a) permits practice through a business entity provided the entity has registered with the board and submitted a description of the services to be practiced and a designation of the individual or individuals in responsible charge, with changes filed within thirty days, and Chapter 5 Section 5 requires any business entity offering to practice to be registered. The document still carries only the individual’s seal: § 33-29-602(a)(iii) requires that all final maps, plats, plans, designs and other documents filed or recorded under § 33-29-801 “shall be dated and bear the signature and seal of a professional engineer or professional land surveyor in responsible charge of the work.”
I have an older Wyoming seal with different wording. Is it still good?
Possibly. Chapter 5 Section 1(b) provides that seals authorized before July 1, 2013 may continue in use, so an older die with different wording is not automatically invalid. A new purchase, though, is built to the current Section 1(a) specification and goes to the board for approval.
