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 Idaho Board of Licensure of Professional Engineers and Professional Land Surveyors, administered by the Idaho Division of Occupational and Professional Licenses and Idaho Code § 54-1215(3)(a), (b) on 21 September 2026 · Updated 21 September 2026
Idaho leaves the design entirely to the board and publishes no dimensions. Idaho Code § 54-1215(3)(e) says only that “The design of the seal shall be as determined by the board,” and IDAPA 24.32.01.200.01 does not list contents: paragraph (a) describes the official seal of the Board itself, paragraphs (b) and (c) only preserve seals prepared and approved before July 1, 2008 and direct a dual licensee to the combined seal “as adopted by the Board.” Do not confuse the Board’s own official seal in paragraph (a) with a licensee seal, and ask the board for the adopted artwork rather than building from a vendor template.
Note the chapter number when you go looking. The current rules are IDAPA 24.32.01. Guidance that cites 24.31.01 is pointing at the wrong chapter.
Everything in § 54-1215(3) applies to engineers and land surveyors alike. The one place the rules single out surveyors is IDAPA 24.32.01.300, which requires a corner record to carry the professional land surveyor’s seal, signed and dated, along with a printed name, the board-issued license number and the employer name. A corner record that carries the stamp but not the printed name and employer is incomplete.

Is a seal required in Idaho?
Idaho puts the whole duty in statute, in unusually operational detail, and applies it identically to both of this board’s professions. Idaho Code § 54-1215(3) requires each licensee on licensure to obtain a seal. Subsection (3)(b) states that the seal, signature and date “shall be placed on all final specifications, land surveys, reports, plats, drawings, plans, design information and calculations whenever presented to a client or any public or governmental agency.” The same subsection catches the preliminary dodge: a document presented to a client or agency that is not final and carries no seal “shall be clearly marked as ‘draft,’ ‘not for construction’ or with similar words,” and a final work product that is preliminary in nature still has to be sealed, signed and dated if it is intended to be relied on for policy decisions affecting life, health, property or public fiscal interest.
What must appear on the seal
- Not specified by statute or rule; the design is whatever the board has adopted
- For a dual licensee, the board-adopted seal showing licensure as a Professional Engineer and Land Surveyor
Not addressed in any published source. Idaho Code § 54-1215(3)(e) says only that “The design of the seal shall be as determined by the board.” IDAPA 24.32.01.200.01 does not list contents: paragraph (a) describes the official seal of the Board itself, which is the seal of the state of Idaho surrounded by the words Board of Professional Engineers and Professional Land Surveyors and State of Idaho, and paragraphs (b) and (c) only preserve seals prepared and approved before July 1, 2008 and direct a dual licensee to the combined seal “as adopted by the Board.” Do not confuse the Board’s own official seal in paragraph (a) with a licensee seal. Copy the content from the board-adopted artwork, not from a template.
Size and shape
Not addressed. No diameter, ratio or shape appears in Idaho Code § 54-1215 or in IDAPA 24.32.01, and the board publishes no dimensioned artwork. Checked IDAPA 24.32.01 by extracting the text layer of the current rule PDF at the Idaho administrative rules site, the Division’s statutes, rules and guidance page for the board, the Ethics and Professional Practice Manual updated 07/10/2025, and the board’s Professional Land Surveyor Guidance Document. None states a size. Note the chapter number: the current rules are IDAPA 24.32.01, not 24.31.01.
Embosser, rubber stamp or digital
Three devices, named in the statute itself: “The seal may be a rubber stamp, crimp or electronically generated image.” The board’s Ethics and Professional Practice Manual confirms that either a seal generated by a CAD system, or a rubber stamp or crimp, meets the requirement. The safe buy is a rubber or self-inking stamp, because § 54-1215(3)(c) requires the seal, signature and date to be placed so that they reproduce when the original is copied, and a crimp alone usually will not.
Signing and dating
Permissive on placement and strict on reproduction. Under § 54-1215(3)(a), whenever the seal is applied “the licensee’s signature and date shall be included adjacent to or across the seal,” so beside the stamp is acceptable and Idaho does not require signing through it. Under (3)(c) the seal, signature and date must be placed so they reproduce when the original is copied, and their application constitutes certification that the work was done by the licensee or under the licensee’s responsible charge. The board’s guidance lists a traditional handwritten signature, a facsimile image of the signature and a digital signature as allowable. For electronic originals distributed as working or bidding copies, (3)(c) allows issuing the seal with a notice that the original is on file, and requires the words “Original Signed By:” and “Date Original Signed:” adjacent to or across the seal plus the storage location of the original.
The corner record is the surveyor-only sealing duty, and there is no published size
Everything in Idaho Code § 54-1215(3) applies to engineers and land surveyors alike. The one place the rules single out surveyors is IDAPA 24.32.01.300, which requires a corner record to carry the professional land surveyor’s seal, signed and dated, along with a printed name, the board-issued license number and the employer name. A corner record that carries the stamp but not the printed name and employer is incomplete.
Which documents must be sealed
All final specifications, land surveys, reports, plats, drawings, plans, design information and calculations presented to a client or any public or governmental agency. Sheet by sheet: “Each plan or drawing sheet shall be sealed and signed and dated by the licensee or licensees responsible for each sheet,” and in a business entity each sheet is sealed by the licensees involved. Reports, specifications and like documents need the seal and signature only on the title page. Carve-outs are narrow: draft or not-for-construction marking for non-final documents, and the restricted license held by engineering faculty, whose holder is not required to obtain a seal. The surveyor-specific addition is the corner record: IDAPA 24.32.01.300 requires a corner record to include the professional land surveyor’s seal, signed and dated by the surveyor, together with a printed name, board-issued license number and employer name. Idaho Code §§ 50-1304 and 55-1905 govern plat and record of survey signature media.
Electronic and digital seals
No technology is named and no board approval process exists. The statute lists an electronically generated image as a permitted seal form, and the board’s guidance treats CAD-generated seals and digital signatures as acceptable without prescribing a standard, a certificate authority or a verification service. Idaho instead controls the risk through the Original Signed By and Date Original Signed convention in § 54-1215(3)(c) for electronically produced copies distributed for bidding or working use.
Renewal, lapse and retirement
Section 54-1215(3) makes it unlawful for any person to affix, or permit to be affixed, the person’s seal and signature to any document after the license has “expired or has been retired, suspended, or revoked,” unless the license has been renewed, reinstated or reissued. Idaho treats retired status as a sealing disqualifier alongside expiration and discipline. Not addressed: neither § 54-1215 nor IDAPA 24.32.01 requires the seal to be destroyed or surrendered, and neither says whether a license number changes on reinstatement. Checked both.
Firm requirements
Required, and enforced at the Secretary of State. Idaho Code § 54-1235(1) requires a business entity practicing or offering to practice land surveying to hold a certificate of authorization from the board, with utilities regulated by the Idaho public utilities commission excepted, and to designate the licensee or licensees in responsible charge, with changes reported within thirty days. Under § 54-1235(5) the Secretary of State may not accept an assumed business name or organizational filing containing engineer, engineering, land surveyor or land surveying, or any derivation, without a certificate or eligibility letter from the board. The firm does not get its own seal and no firm number is required on the document. Section 54-1235(1) instead requires that all final drawings, specifications, plats, reports or other papers prepared or approved for delivery or public record “shall be dated and bear the signature and seal of the professional engineer or professional land surveyor who prepared or approved them.”
What to check before you order
Ask the board for the seal design it has adopted, because Idaho Code § 54-1215(3)(e) leaves the design to the board and neither the statute nor IDAPA 24.32.01 states a diameter or an element list. A rubber stamp, a crimp or an electronically generated image are all permitted; buy a stamp, because the seal, signature and date must be placed so they reproduce when the original is copied. Sign and date adjacent to or across the seal. Seal and sign every plan or drawing sheet; for reports and specifications the title page is enough. If you prepare corner records, remember that the rule wants the seal plus your printed name, your board-issued license number and your employer name. If you hold both licenses, ask for the combined engineer and land surveyor seal the board has adopted rather than ordering two.

Frequently asked questions
Is a seal required for land surveyors in Idaho?
Yes, and the statute is unusually operational. Idaho Code § 54-1215(3) requires each licensee on licensure to obtain a seal, and subsection (3)(b) states that the seal, signature and date “shall be placed on all final specifications, land surveys, reports, plats, drawings, plans, design information and calculations whenever presented to a client or any public or governmental agency.”
What has to appear on an Idaho land surveyor seal?
The statute and rule do not say. Section 54-1215(3)(e) delegates the design to the board, and IDAPA 24.32.01.200.01 lists no contents. Copy the content from the board-adopted artwork. If you hold both licenses, paragraph (c) directs you to the combined engineer and land surveyor seal as adopted by the Board rather than to two separate devices.
What size is an Idaho land surveyor seal?
No diameter, ratio or shape appears in Idaho Code § 54-1215 or in IDAPA 24.32.01, and the board publishes no dimensioned artwork. The Division’s statutes, rules and guidance page, the Ethics and Professional Practice Manual updated 07/10/2025 and the board’s Professional Land Surveyor Guidance Document all state none.
Rubber stamp, crimp or electronic in Idaho?
All three are named in the statute: “The seal may be a rubber stamp, crimp or electronically generated image.” The board’s Ethics and Professional Practice Manual confirms that a seal generated by a CAD system, or a rubber stamp or crimp, meets the requirement. A rubber or self-inking stamp is the safe buy, because § 54-1215(3)(c) requires the seal, signature and date to be placed so they reproduce when the original is copied, and a crimp alone usually will not.
Where do the signature and date go in Idaho?
Adjacent to or across the seal, your choice. Under § 54-1215(3)(a), whenever the seal is applied “the licensee’s signature and date shall be included adjacent to or across the seal.” Under (3)(c) all three must be placed so they reproduce when the original is copied, and their application certifies that the work was done by you or under your responsible charge. The board’s guidance lists a traditional handwritten signature, a facsimile image of the signature and a digital signature as allowable.
What does Idaho require on an electronically distributed working copy?
A pointer to the original. For electronic originals distributed as working or bidding copies, § 54-1215(3)(c) allows issuing the seal with a notice that the original is on file, and requires the words “Original Signed By:” and “Date Original Signed:” adjacent to or across the seal plus the storage location of the original. That convention is how Idaho controls the electronic risk, rather than by naming a technology, a standard, a certificate authority or a verification service.
How does Idaho handle preliminary documents?
By marking, and with one catch. A document presented to a client or agency that is not final and carries no seal “shall be clearly marked as ‘draft,’ ‘not for construction’ or with similar words,” and a final work product that is preliminary in nature still has to be sealed, signed and dated if it is intended to be relied on for policy decisions affecting life, health, property or public fiscal interest.
Does every sheet need sealing in Idaho?
Every plan or drawing sheet: “Each plan or drawing sheet shall be sealed and signed and dated by the licensee or licensees responsible for each sheet,” and in a business entity each sheet is sealed by the licensees involved. Reports, specifications and like documents need the seal and signature only on the title page. Idaho Code §§ 50-1304 and 55-1905 govern plat and record of survey signature media.
What has to be on an Idaho corner record?
More than the seal. IDAPA 24.32.01.300 requires a corner record to include the professional land surveyor’s seal, signed and dated by the surveyor, together with a printed name, the board-issued license number and the employer name.
When must I stop sealing in Idaho?
On expiration, retirement, suspension or revocation. Section 54-1215(3) makes it unlawful for any person to affix, or permit to be affixed, the person’s seal and signature to any document after the license has “expired or has been retired, suspended, or revoked,” unless the license has been renewed, reinstated or reissued. Idaho treats retired status as a sealing disqualifier, which catches surveyors who take retired status and keep signing the occasional favor. Neither § 54-1215 nor IDAPA 24.32.01 requires the seal to be destroyed or surrendered, and neither says whether a license number changes on reinstatement.
Does an Idaho surveying business need a certificate of authorization?
Yes, and it is enforced at the Secretary of State. Idaho Code § 54-1235(1) requires a business entity practicing or offering to practice land surveying to hold a certificate of authorization from the board, with utilities regulated by the Idaho public utilities commission excepted, and to designate the licensee or licensees in responsible charge, with changes reported within thirty days. Under § 54-1235(5) the Secretary of State may not accept an assumed business name or organizational filing containing engineer, engineering, land surveyor or land surveying, or any derivation, without a certificate or eligibility letter from the board. The firm gets no seal and no firm number is required on the document.
