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 Wisconsin Examining Board of Architects, Landscape Architects, Professional Engineers, Designers, Professional Land Surveyors, and Registered Interior Designers and Wis. Admin. Code § A-E 2.02(4) on 21 September 2026 · Updated 21 September 2026
Your city is a required element of a Wisconsin seal. A-E 2.02(1) lists exactly three things: “Each seal shall include the credential holder’s name, credential number and city.” City, not state and not county. Very few states ask for one, so a stamp ordered from a national template will simply lack the line, and an architect who moves practice from Madison to Milwaukee has a seal whose required content no longer matches.
The overall diameter may not be less than 1-5/8 inches nor more than 2 inches. Wisconsin is a range state rather than a fixed-dimension state, which is why a 1-3/4 inch die cut for another jurisdiction usually passes here on size while still failing on content for want of the city.
Check the date of any guidance you are working from. A-E 2.02(3) was repealed and recreated by CR 24-028, Register May 2025 No. 833, effective 1 June 2025, and now reads that “The registration seal may be an embossing seal, an ink stamp seal, a digitally printed seal, or digitally embedded seal in an electronic file.” The three permitted seal and signature combinations in A-E 2.02(7)(b) arrived in the same action and the old A-E 2.02(7)(a) was repealed outright, so Wisconsin sealing guidance written before mid-2025 describes rules that no longer exist.

Is a seal required in Wisconsin?
The operative duty is in the board rule and it runs sheet by sheet. Wis. Admin. Code § A-E 2.02(4) provides that “Each sheet of plans, drawings, documents, specifications, and reports for architectural, landscape architectural, professional engineering, design, professional land surveying, and registered interior design practice shall be signed, sealed, and dated by the credential holder who prepared, or directed and controlled preparation of, the written material,” subject only to the bound-volume exception in sub. (5). The statute reinforces it for work issued through a business: Wis. Stat. § 443.08(4)(b) requires final drawings, specifications, plans, reports and other papers prepared for the use of a firm, partnership or corporation, for delivery to any person or for public record, to “be dated and bear the signature and seal” of the architect in responsible charge.
What must appear on the seal
- Your name as credentialed
- Your credential number
- Your city
Wisconsin’s element list is short and one entry is unusual. A-E 2.02(1) requires that “Each seal shall include the credential holder’s name, credential number and city.” City, not state and not county. An architect seal cut from an out-of-state template that carries only a name and a number is missing a required element, and an architect who moves practice to another Wisconsin city has a seal whose accuracy has lapsed. The rule text itself does not require the word Wisconsin, the profession name or an expiration date; those come from the approved designs, which A-E 2.02(2) supplies as a diagram rather than as words. That diagram is published as an image attached to A-E 2.02(2) and contains no extractable text, so the ring wording and layout have to be copied from the published diagram rather than quoted from the rule.
Size and shape
Not less than 1-5/8 inches and not more than 2 inches overall diameter. A-E 2.02(1): “The overall diameter may not be less than 15/8 inches nor more than 2 inches.” Wisconsin is a range state rather than a fixed-dimension state, which is why a 1-3/4 inch die cut for another jurisdiction usually passes here on size while still failing on content for want of the city.
Embosser, rubber stamp or digital
All four common devices are legal, and this paragraph was rewritten recently. A-E 2.02(3) now reads that “The registration seal may be an embossing seal, an ink stamp seal, a digitally printed seal, or digitally embedded seal in an electronic file.” That text was repealed and recreated by CR 24-028, published in Register May 2025 No. 833, effective 1 June 2025, so guidance written before mid-2025 describes a narrower list. The safe buy is an ink stamp seal sized between 1-5/8 and 2 inches, with the same artwork supplied as the digitally printed or embedded version.
Signing and dating
A-E 2.02(7)(b) gives three permitted combinations for seals on documents filed as public documents: physical placement of a seal with a handwritten signature in permanent ink containing the name of the credential holder and date; digital placement of a seal with a handwritten signature in permanent ink containing the name and date; or digital placement of a seal with an electronic signature containing the name and date. A date is required in all three. Signing across the face of the seal is not required and not mentioned; the rule speaks of placing a seal and a signature. A-E 2.02(7)(c) yields to other law: “If other standards for signatures or seals are prescribed by statute, the statutes shall govern.” Watch the numbering, because A-E 2.02(7)(a) was repealed by CR 24-028 and older references to it are dead.
Your city is a required element, and the device list changed in June 2025
A-E 2.02(1) lists exactly three things a Wisconsin seal must include: the credential holder’s name, the credential number and the city. Very few states ask for a city. An architect who moves practice from Madison to Milwaukee has a seal whose required content no longer matches, and a stamp ordered from a national template will simply lack the line.
The second thing to know is the date of the current rule. A-E 2.02(3) was repealed and recreated by CR 24-028, Register May 2025 No. 833, effective 1 June 2025, and now reads that “The registration seal may be an embossing seal, an ink stamp seal, a digitally printed seal, or digitally embedded seal in an electronic file.” The three permitted seal and signature combinations in A-E 2.02(7)(b) arrived in the same action, and the old A-E 2.02(7)(a) was repealed outright. Wisconsin sealing guidance written before mid-2025 is describing rules that no longer exist.
Third, the approved seal designs at A-E 2.02(2) are published as a diagram and not as rule text. You cannot derive the ring wording from the words of the regulation, so copy the published design rather than letting a supplier infer it.
One stale signal to ignore: the Wisconsin Legislature site shows an alert that ch. A-E 2 may be affected by emergency rule EmR2038. That emergency rule concerned retired credential status, took effect 1 December 2020, expired no later than 1 May 2021 and was superseded by permanent rule CR 20-064. It has nothing to do with seals.
Which documents must be sealed
Every sheet, by default. The bound-volume relief in A-E 2.02(5) lets the credential holder who prepared or directed and controlled a bound volume sign, seal and date only the title or index sheet, provided that sheet clearly identifies all the other sheets and that any sheets prepared under another credential holder are separately signed, sealed and dated by that person. Revisions have their own rule: A-E 2.02(6) bars any addition, deletion or other revision affecting public health and safety or any state or local code requirement unless it is signed, sealed and dated by the credential holder who made or directed it. Two statutory carve-outs sit in Wis. Stat. § 443.15: single-family dwellings and their outbuildings, two-family apartment buildings, buildings used exclusively for agriculture, temporary construction sheds of not more than two stories, and buildings or additions under 50,000 cubic feet total volume. A-E 2.02(8) sets the terms on which plans prepared by an out-of-state architect may be filed by a Wisconsin credential holder, requiring both the original preparer’s seal and signature and a separate dated, signed and sealed certificate from the Wisconsin submitter.
Electronic and digital seals
No named technology. Wisconsin’s electronic route is A-E 2.02(7)(b)3, which permits digital placement of a seal with an electronic signature containing the name of the credential holder and date, and A-E 2.02(3), which recognizes a digitally printed seal and a digitally embedded seal in an electronic file. The board names no certificate authority, no cryptographic algorithm and no tamper-evidence test, and imposes no four-part digital signature criteria of the kind several neighboring states spell out. Both provisions arrived with CR 24-028 effective 1 June 2025, so any Wisconsin digital-sealing guidance dated before then is describing a repealed rule.
Renewal, lapse and retirement
A credential not renewed by the renewal date can be renewed on payment of the renewal fee if the application comes within five years of expiration, under A-E 2.05(1). Past five years, A-E 2.05(2) requires the relevant section of the board to decide whether the applicant is still competent to practice, to review the last five years of practice in other jurisdictions and to impose conditions that may include completing current original-licensure requirements. A-E 2.045 provides retired status for a credential holder who is at least 65 or has actively maintained the credential for at least 20 years and certifies they no longer practice. Using a dead credential is criminal rather than merely administrative: Wis. Stat. § 443.18(1)(a) reaches “any person who attempts to use an expired or revoked certificate of registration” with a fine of $100 to $500 or up to three months imprisonment or both. Neither the statute nor ch. A-E 2 requires the seal to be destroyed or surrendered, and neither says the credential number changes.
Firm requirements
A certificate of authorization is required, but the firm gets no seal and no number on the sheet. Wis. Stat. § 443.08(2) bars an individual architect from practicing as a principal, officer, employee or agent of a firm, partnership or corporation unless all personnel practicing on its behalf are credentialed and “The firm, partnership, or corporation has been issued a certificate of authorization” under sub. (3)(a). The board rule caught up on 1 July 2026: A-E 2.03(5), created by CR 25-082, Register June 2026 No. 846, carries the same prohibition and exempts a sole proprietorship practicing under the same name as the individual. Nothing in § 443.08 or ch. A-E 2 requires a firm seal or the certificate number on a document; § 443.08(4)(b) puts the individual’s signature and seal on the firm’s final documents instead.
What to check before you order
Ask for an overall diameter between 1-5/8 and 2 inches and make sure three items appear without fail: your name as credentialed, your credential number and your city. The city is the one suppliers leave off, so say it twice. Send them the approved design diagram attached to A-E 2.02(2) in the published administrative code for the ring layout, because that layout exists only as an image and cannot be reconstructed from the rule’s words. Ask for the same artwork as a digitally printed and digitally embeddable file as well as an ink stamp, since A-E 2.02(3) now recognizes both and you will need them. Reorder if you move your practice to another city. Wisconsin asks nothing of the supplier by way of proof of credential.

Frequently asked questions
Is an architect seal required in Wisconsin?
Yes, and the duty runs sheet by sheet. Wis. Admin. Code § A-E 2.02(4) provides that “Each sheet of plans, drawings, documents, specifications, and reports for architectural, landscape architectural, professional engineering, design, professional land surveying, and registered interior design practice shall be signed, sealed, and dated by the credential holder who prepared, or directed and controlled preparation of, the written material,” subject only to the bound-volume exception in sub. (5). Wis. Stat. § 443.08(4)(b) requires final drawings, specifications, plans, reports and other papers prepared for the use of a firm, partnership or corporation, for delivery to any person or for public record, to “be dated and bear the signature and seal” of the architect in responsible charge.
What has to appear on a Wisconsin architect seal?
Three items under A-E 2.02(1): your name as credentialed, your credential number and your city. The rule text itself does not require the word Wisconsin, the profession name or an expiration date; those come from the approved designs, which A-E 2.02(2) supplies as a diagram rather than as words. That diagram is published as an image and contains no extractable text, so the ring wording and layout have to be copied from the published diagram rather than reconstructed from the rule.
What size is a Wisconsin architect seal?
A-E 2.02(1): “The overall diameter may not be less than 15/8 inches nor more than 2 inches.” You choose within the band.
Can I use an embosser in Wisconsin?
Yes. A-E 2.02(3) now reads that “The registration seal may be an embossing seal, an ink stamp seal, a digitally printed seal, or digitally embedded seal in an electronic file.” An ink stamp seal sized between 1-5/8 and 2 inches is the practical buy, with the same artwork supplied as the digitally printed or embedded version.
How do I sign and seal a Wisconsin public document?
A-E 2.02(7)(b) gives three permitted combinations: physical placement of a seal with a handwritten signature in permanent ink containing the name of the credential holder and date; digital placement of a seal with a handwritten signature in permanent ink containing the name and date; or digital placement of a seal with an electronic signature containing the name and date. A date is required in all three. Signing across the face of the seal is not required and not mentioned. A-E 2.02(7)(c) yields to other law: “If other standards for signatures or seals are prescribed by statute, the statutes shall govern.” Watch the numbering, because A-E 2.02(7)(a) was repealed by CR 24-028.
Can I seal just the title sheet in Wisconsin?
Only for a bound volume. A-E 2.02(5) lets the credential holder who prepared or directed and controlled a bound volume sign, seal and date only the title or index sheet, provided that sheet clearly identifies all the other sheets and that any sheets prepared under another credential holder are separately signed, sealed and dated by that person. Otherwise every sheet is sealed.
Do revisions need a Wisconsin seal?
Yes, where they touch safety or code. A-E 2.02(6) bars any addition, deletion or other revision affecting public health and safety or any state or local code requirement unless it is signed, sealed and dated by the credential holder who made or directed it.
Which Wisconsin projects are exempt?
Two statutory carve-outs sit in Wis. Stat. § 443.15: single-family dwellings and their outbuildings, two-family apartment buildings, buildings used exclusively for agriculture, temporary construction sheds of not more than two stories, and buildings or additions under 50,000 cubic feet total volume.
Can I file an out-of-state architect’s plans in Wisconsin?
On terms. A-E 2.02(8) requires both the original preparer’s seal and signature and a separate dated, signed and sealed certificate from the Wisconsin submitter.
Does Wisconsin name a digital signature standard?
No. The electronic route is A-E 2.02(7)(b)3, which permits digital placement of a seal with an electronic signature containing the name of the credential holder and date, and A-E 2.02(3), which recognizes a digitally printed seal and a digitally embedded seal in an electronic file. The board names no certificate authority, no cryptographic algorithm and no tamper-evidence test, and imposes no four-part digital signature criteria of the kind several neighboring states spell out. Both provisions arrived with CR 24-028 effective 1 June 2025.
What happens if I use an expired Wisconsin credential?
It is criminal rather than merely administrative. Wis. Stat. § 443.18(1)(a) reaches “any person who attempts to use an expired or revoked certificate of registration” with a fine of $100 to $500 or up to three months imprisonment or both. On renewal, a credential not renewed by the renewal date can be renewed on payment of the renewal fee if the application comes within five years of expiration under A-E 2.05(1); past five years, A-E 2.05(2) requires the relevant section of the board to decide whether the applicant is still competent to practice, to review the last five years of practice in other jurisdictions and to impose conditions. A-E 2.045 provides retired status for a credential holder who is at least 65 or has actively maintained the credential for at least 20 years and certifies they no longer practice. Neither the statute nor ch. A-E 2 requires the seal to be destroyed or surrendered, and neither says the credential number changes.
Does a Wisconsin architecture firm need a certificate of authorization?
Yes, and the firm gets no seal and no number on the sheet. Wis. Stat. § 443.08(2) bars an individual architect from practicing as a principal, officer, employee or agent of a firm, partnership or corporation unless all personnel practicing on its behalf are credentialed and “The firm, partnership, or corporation has been issued a certificate of authorization” under sub. (3)(a). The board rule caught up on 1 July 2026: A-E 2.03(5), created by CR 25-082, Register June 2026 No. 846, carries the same prohibition and exempts a sole proprietorship practicing under the same name as the individual. Nothing in § 443.08 or ch. A-E 2 requires a firm seal or the certificate number on a document.
