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 Alabama State Board of Registration for Interior Design and Ala. Admin. Code r. 485-X-4-.01(2), (5), (6) on 21 September 2026 · Updated 21 September 2026
Circular, exactly two inches, and your firm name may not go on it. Rule 485-X-4-.01(3) is short and exact: “The seal shall be circular, two inches in diameter,” carrying STATE OF ALABAMA across the top of the outer circle, REGISTERED INTERIOR DESIGNER across the bottom, and your name and registration number inside the inner circle. The same subsection adds a prohibition that catches design studios out: “Seals are for individual use only and are not to utilize the name of the business entity.” Subsection (4) shows an example at actual size.
The rule creates a power before it creates a duty, and both matter. Rule 485-X-4-.01(2) provides that on approval of valid registration an interior designer “may create his/her own seal for use in the issuing of plans, specifications, and other documents for the purpose of obtaining construction permits,” and subsection (5) then makes it an obligation where it counts: “The registrant’s seal must be affixed on all final drawings, plans, specifications, and reports whenever presented to a client or any public or governmental agency for the purpose of obtaining a permit for construction.”
Alabama goes one step further than any other board in the state and supplies the artwork. Subsection (5) provides that “To ensure consistency and continuity the Board shall, with a fee, offer an electronic seal in AutoCAD format,” requested in writing with the fee. That removes the guesswork about layout, and it also means a device that does not match the Board file is hard to defend.

Is a seal required in Alabama?
Alabama registers interior designers and gives them a seal, but the rule creates a power before it creates a duty. Rule 485-X-4-.01(2) provides that “Upon approval of valid registration, an interior designer may create his/her own seal for use in the issuing of plans, specifications, and other documents for the purpose of obtaining construction permits.” Subsection (5) then turns that into an obligation for the documents that matter: “The registrant’s seal must be affixed on all final drawings, plans, specifications, and reports whenever presented to a client or any public or governmental agency for the purpose of obtaining a permit for construction.” Subsection (6) states the meaning of the act: by affixing the seal the registrant signifies the document was prepared personally or under direct supervision.
What must appear on the seal
- STATE OF ALABAMA across the top of the outer circle
- REGISTERED INTERIOR DESIGNER across the bottom of the outer circle
- Your name inside the inner circle
- Your registration number inside the inner circle
One prohibition is explicit and commercially important: “Seals are for individual use only and are not to utilize the name of the business entity.” A design firm cannot put its trading name on a registrant’s seal. The geometry is fixed the same way the Alabama architect seal is fixed, with the two legends in the outer circle and the name and number in the inner circle, and subsection (4) shows an example at actual size. No expiration date, no renewal date and no discipline belongs on the face.
Size and shape
Circular, two inches in diameter. Rule 485-X-4-.01(3) is exact: “The seal shall be circular, two inches in diameter.” That matches the Alabama architect figure and differs from the Alabama engineer and land surveyor band of 1 5/8 to 2 inches.
Embosser, rubber stamp or digital
“Seals may be a rubber stamp, an impression seal, or a computer-generated seal, as allowed by jurisdiction.” Alabama goes one step further than any other board in the state and sells the artwork: subsection (5) provides that “To ensure consistency and continuity the Board shall, with a fee, offer an electronic seal in AutoCAD format,” requested in writing with the fee. The safe buy is a two inch rubber stamp, with the Board’s AutoCAD file for drawing sets, because the rule closes by saying seals must conform to the requirements of the authority having jurisdiction under which the documents are submitted.
Signing and dating
Not addressed. Chapter 485-X-4 requires the seal to be affixed and states no signature requirement, no date requirement and no placement rule. The sources here are rule 485-X-4-.01 in full and rule 485-X-4-.02, and the chapter list for agency 485, which runs from composition of the Board through disciplinary action with no separate signature chapter. Contrast Alabama landscape architects, whose rule 500-X-2-.07(3)(b) expressly addresses an electronically generated signature and date of signature.
The Board sells you the artwork, and your firm name may not go on it
Alabama is one of the few states that will hand a registered interior designer a ready-made electronic seal. Rule 485-X-4-.01(5) provides that the Board shall, with a fee, offer an electronic seal in AutoCAD format on written request. That removes most of the guesswork about layout, and it also means a stamp that does not match the Board file is hard to defend.
Which documents must be sealed
All final drawings, plans, specifications and reports presented to a client or any public or governmental agency for a construction permit. Work products presented that are not final “should be so identified as ‘unfinished’, ‘draft’, or ‘not for construction’.” Note the word should rather than shall in that sentence; the sealing obligation in the same subsection uses must. Chapter 485-X-6 carries the exemptions from registration.
Electronic and digital seals
Alabama does not set a digital signature standard for interior designers and instead controls the artwork. The Board offers, for a fee and on written request, an electronic seal in AutoCAD format, and permits a computer-generated seal “as allowed by jurisdiction.” No verification criteria, no certificate authority and no stripping language for uncertified transmissions appear in chapter 485-X-4. The sources here are rules 485-X-4-.01 and 485-X-4-.02 in full.
Renewal, lapse and retirement
Rule 485-X-4-.02 provides that certificates and seals may be suspended or revoked through disciplinary action consistent with the Alabama Administrative Procedure Act, that the Board may set terms for reinstatement, and that “Reinstatement of certificates and seals will be required for any certificate which has been suspended or revoked through disciplinary action.” Alabama therefore treats the seal itself, not only the certificate, as something that is suspended and reinstated. Not addressed: whether the registration number changes on reinstatement, and whether the physical device must be surrendered or destroyed. Checked chapter 485-X-4 in full.
Firm requirements
Not applicable. Alabama issues no certificate of authorization for interior design and prescribes no firm seal. The rule goes the other way and bars the firm from the face of the device: “Seals are for individual use only and are not to utilize the name of the business entity.” Compare Alabama architects, where rule 100-X-8-.01 requires an entity Certificate of Authorization, and Alabama engineers and land surveyors, where Code of Ala. 1975, § 34-11-9(a)(1) requires one.
What to check before you order
Order a circular device exactly two inches in diameter, with STATE OF ALABAMA at the top and REGISTERED INTERIOR DESIGNER at the bottom of the outer circle, and your name and registration number inside the inner circle. Keep your firm or studio name off it; the rule restricts the seal to individual use and forbids the business entity name. A rubber stamp, an impression seal or a computer-generated seal is acceptable as the jurisdiction allows, and you can buy the Board’s own AutoCAD seal file for a fee by writing in. Seal every final drawing, plan, specification and report that goes to a client or to a permitting agency, and mark anything unfinished as draft or not for construction. If your registration is ever suspended or revoked, the seal is suspended or revoked with it and has to be reinstated.

Frequently asked questions
Is a seal required for an Alabama registered interior designer?
On the documents that matter, yes. Rule 485-X-4-.01(5) requires the seal on all final drawings, plans, specifications and reports presented to a client or any public or governmental agency for the purpose of obtaining a construction permit. Subsection (2) frames the seal as something you may create on registration, and subsection (5) is what turns that into a duty.
What has to appear on an Alabama interior designer seal?
Four items under rule 485-X-4-.01(3): STATE OF ALABAMA across the top of the outer circle, REGISTERED INTERIOR DESIGNER across the bottom of it, your name inside the inner circle, and your registration number inside the inner circle. No expiration date, no renewal date and no discipline line belongs on the face.
Can my studio name go on the Alabama seal?
No. Rule 485-X-4-.01(3) states that “Seals are for individual use only and are not to utilize the name of the business entity.” A firm that has always put its trading name on drawings cannot put it on the seal, and only your name and registration number belong inside the inner circle.
What size is the Alabama interior designer seal?
Two inches in diameter, stated as a single figure. That matches the Alabama architect seal and differs from the Alabama engineer and land surveyor band of 1-5/8 to 2 inches, so a supplier working from an engineering template may offer you something undersized.
Can I get the Alabama seal artwork from the Board?
Yes, for a fee. Rule 485-X-4-.01(5) provides that the Board shall, with a fee, offer an electronic seal in AutoCAD format, requested in writing with the fee. Starting from the Board file is the straightforward way to get the geometry right.
Rubber stamp, impression seal or computer-generated in Alabama?
All three. Rule 485-X-4-.01(2) provides that “Seals may be a rubber stamp, an impression seal, or a computer-generated seal, as allowed by jurisdiction.” A two inch rubber stamp is the practical buy, with the Board’s AutoCAD file for drawing sets, because the rule closes by requiring seals to conform to the requirements of the authority having jurisdiction under which the documents are submitted.
Does Alabama require a signature and date beside the seal?
Chapter 485-X-4 requires the seal to be affixed and states no signature requirement, no date requirement and no placement rule. Rules 485-X-4-.01 and 485-X-4-.02, and the agency 485 chapter list running from composition of the Board through disciplinary action, contain no separate signature chapter. That is lighter than Alabama landscape architects, whose rule 500-X-2-.07(3)(b) expressly addresses an electronically generated signature and date of signature.
Which Alabama documents get the seal?
All final drawings, plans, specifications and reports presented to a client or any public or governmental agency for a construction permit. Work products that are not final “should be so identified as ‘unfinished’, ‘draft’, or ‘not for construction’.” Note the difference in force: that sentence says should, while the sealing obligation in the same subsection says must. Chapter 485-X-6 carries the exemptions from registration.
What does affixing the Alabama seal mean?
Rule 485-X-4-.01(6) states it: by affixing the seal you signify that the document was prepared personally or under your direct supervision. That is the whole legal weight of the act, which is why the device is individual and the business name is barred from it.
Can I apply the Alabama seal electronically?
Yes. A computer-generated seal is permitted “as allowed by jurisdiction,” and the Board sells an electronic seal in AutoCAD format for a fee. Alabama sets no digital signature standard for interior designers and controls the artwork instead: no verification criteria, no certificate authority and no stripping language for uncertified transmissions appear in chapter 485-X-4.
What happens to my Alabama seal on suspension or revocation?
It is suspended or revoked with the certificate. Rule 485-X-4-.02 provides that certificates and seals may be suspended or revoked through disciplinary action consistent with the Alabama Administrative Procedure Act, that the Board may set terms for reinstatement, and that “Reinstatement of certificates and seals will be required for any certificate which has been suspended or revoked through disciplinary action.” Most states discipline the license and say nothing about the device. Whether the registration number changes on reinstatement, and whether the physical device must be surrendered, the chapter does not say.
Does an Alabama interior design firm need a certificate of authorization?
No. Alabama issues no certificate of authorization for interior design and prescribes no firm seal, and the rule goes the other way by barring the business entity name from the face of the device. That differs from Alabama architects, where rule 100-X-8-.01 requires an entity Certificate of Authorization, and from Alabama engineers and land surveyors, where Code of Ala. 1975, § 34-11-9(a)(1) requires one.
