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 fixes the circles exactly: one and three-quarter inches outer, one and one-quarter inches inner. The board 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.” These are exact values, not minimums. Do not take the one and one-half to two inch band that Wyoming’s architects and landscape architects work with; a one and seven-eighths inch die is lawful for a Wyoming architect and wrong for a Wyoming land surveyor.
The band between the circles carries Professional Land Surveyor above and Wyoming below. The inner circle carries your name, your license number and the word Date. Wyoming also tells you what must not appear: the license number goes centered in the inner area in the space occupied by the word NUMBER, the numerals must be no larger than the word NAME, and “The words and parentheses ‘(NUMBER)’, and ‘(NAME)’, should not appear on the seal.” Those placeholders come straight off the Board’s layout template, and dies do get cut with them still in place.
Signing works differently here too. Chapter 5 Section 1(c) requires that “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.” Those two demands pull against each other, which is why an inked stamp at the exact outer diameter beats a crimp: the impression has to read through the signature on the recorded plat.

Is a seal required in Wyoming?
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 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.”
What must appear on the seal
- Professional Land Surveyor in the upper annular space, or Professional Engineer & Land Surveyor if you hold both
- 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). There is no expiration date and no discipline line.
Size and shape
Two concentric circles: outer circle one and three-quarter inches diameter, inner circle one and one-quarter 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 circles carries the title phrase above and Wyoming below; the inner circle carries name, number and the word Date. Do not take the architect and landscape architect band of one and one-half to two inches from the other Wyoming board.
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 one and three-quarter 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.
Two Wyoming boards, two incompatible seal geometries
Wyoming prescribes exact circles for surveyors and a size band for architects. The engineering and land surveying board fixes two concentric circles at one and three-quarter inches outer and one and one-quarter inches inner. The architects and landscape architects board allows anything from one and one-half to two inches in diameter. A one and seven-eighths inch die is lawful for a Wyoming architect and wrong for a Wyoming land surveyor, and a vendor working one template for the state will produce one of them incorrectly.
Which documents must be sealed
Everything filed or recorded under Wyo. Stat. § 33-29-801, which is the practical universe of Wyoming public-record 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 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. Chapter 5 Section 4 and Chapter 7, the Corner Perpetuation and Filing Act, add land surveying practice requirements that do not change the seal itself.
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.
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 requirements
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. 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.
What to check before you order
Order a circular device with two concentric circles, the outer exactly one and three-quarter inches and the inner exactly one and one-quarter inches. Put Professional Land Surveyor in the upper annular space and Wyoming at the bottom, and put your name, your license number and the word Date inside the inner circle, with the number centered and the numerals no larger than the word NAME. Strip the template placeholders: the words and parentheses (NUMBER) and (NAME) must not appear on the seal. A crimp type or a rubber stamp facsimile is authorized, and an electronically generated seal is allowed if it matches the same design; a rubber or self-inking stamp is the practical choice because the signature and date have to be superimposed over the seal and the seal must remain legible in its entirety. If you hold both credentials the rule gives you a Professional Engineer & Land Surveyor variant.

Frequently asked questions
Is a seal required for land surveyors in Wyoming?
Yes, and it is pinned to recording. Wyo. Stat. § 33-29-601(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 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 signed by and bear the seal of the professional engineer or professional land surveyor.”
What has to appear on a Wyoming land surveyor seal?
Five elements under Chapter 5 Section 1(a): Professional Land Surveyor in the upper annular space, the inscription Wyoming at the bottom of the annular space, and your name, your license number and the word Date inside the inner circle. If you hold both credentials the rule gives you a Professional Engineer & Land Surveyor variant. There is no expiration date and no discipline line.
What size is a Wyoming land surveyor seal?
Two concentric circles, the outer exactly one and three-quarter inches in diameter and the inner exactly one and one-quarter inches. The rule states them as values rather than as a range, so there is no tolerance to work inside.
Crimp or rubber stamp in Wyoming?
Both are named. The seal authorized by the Board “is of the crimp type and/or rubber stamp facsimile”, and electronically generated seals are separately allowed under Chapter 5 Section 1(c) provided they are accompanied by the licensee’s signature and date and comply with the design in subsection (a). A rubber or self-inking stamp at exactly one and three-quarter inches outside diameter is the practical choice, because the imprint has to stay legible in its entirety with your signature written over it.
Does the signature go over the seal in Wyoming?
Yes. Chapter 5 Section 1(c) requires the signature of the licensee and the date of signing to be superimposed over the seal, and requires the seal to be legible in its entirety to be valid. 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.
Can I use a scanned signature in Wyoming?
Yes, with a date. Chapter 5 Section 1(f) permits a scanned image or other reproduction of an original signature in lieu of an original or digital signature if it is accompanied by the date of signature. Section 1(e) separately 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.
Which Wyoming documents need the seal?
Everything filed or recorded under Wyo. Stat. § 33-29-801, which is the practical universe of Wyoming public-record surveying documents, plus the final designs, specifications, maps, land surveys, reports, plats, drawings and plans listed in § 33-29-601(c). 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.
Can I seal work someone else performed in Wyoming?
Not without a thorough technical review. 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 that review is done. Chapter 5 Section 4 and Chapter 7, the Corner Perpetuation and Filing Act, add land surveying practice requirements that do not change the seal itself.
How does electronic submittal work in Wyoming?
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. Under Section 1(e), any hard copy printed from a 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. A digital signature using a process approved by the board is presumed to meet the four-part standard.
Does inactive status kill my Wyoming seal?
Yes, and that is broader than most states. 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. Renewal, retired status, failure to timely renew, reactivation, relicensure and reinstatement are in Chapter 4 of the board rules. Neither the statute nor Chapter 5 requires the seal to be destroyed or surrendered, and neither says whether a license number changes on relicensure.
Does a Wyoming surveying business need its own seal?
No. 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 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. The document still carries only the individual’s seal: § 33-29-602(a)(iii) requires that 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 goes on the face.
