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 New Jersey State Board of Architects, through its Interior Design Examination and Evaluation Committee and N.J.A.C. 13:27 on 21 September 2026 · Updated 21 September 2026
New Jersey does certify interior designers, and the credential sits with the State Board of Architects. The Division of Consumer Affairs lists an Interior Design Examination and Evaluation Committee among its professional and occupational boards and committees, and the State Board of Architects states that all Certified Interior Designer matters, including applications, complaints, examinations, verification of licensure, renewals and reinstatements, are handled by its own staff. That places the credential in N.J.A.C. 13:27, the architects chapter, rather than in the engineers and land surveyors chapter.
Which is what rules out the New Jersey rule everyone quotes. N.J.A.C. 13:40-8.1(a) recognizes only a digital seal or an impression type seal and refuses rubber stamp facsimiles, and it is a rule of the State Board of Professional Engineers and Land Surveyors binding that board’s two licensee types. It does not reach certified interior designers, architects or landscape architects. A blanket claim that New Jersey prohibits rubber stamp seals across the design professions is wrong on its face.
What the seal requirement itself is, and whether there is one, sits in the codified text of N.J.A.C. 13:27, which the Board no longer publishes directly. Its Laws and Regulations page sends licensees either to a portal that requires accepting terms of use or to an unofficial republication the Board itself flags as possibly not current. Ask the Board for the certified interior designer provisions before you order anything, and do not take a supplier’s word for a New Jersey interior designer specification.

Is a seal required in New Jersey?
New Jersey certifies interior designers rather than leaving the field unregulated. The Division of Consumer Affairs lists an Interior Design Examination and Evaluation Committee among its professional and occupational boards and committees, and the State Board of Architects states that all Certified Interior Designer matters, including applications, complaints, examinations, verification of licensure, renewals and reinstatements, are handled by its own staff. The credential therefore sits under the architects chapter, N.J.A.C. 13:27, and not under the engineers and land surveyors chapter. Whether a seal is required of a New Jersey Certified Interior Designer, and what it must carry, sits in that codified text, which is not published in readable form.
What must appear on the seal
- Your name as licensed and your license number
Not addressed from a primary source. The Board points licensees to N.J.A.C. 13:27 through the New Jersey Office of Administrative Law text hosted on LexisNexis, whose landing page requires accepting terms and conditions before the text opens, and otherwise to the Justia unofficial code, which the Board itself describes as possibly not current. We did not accept the terms gate and we do not rely on an unofficial republication. Ask the Board for the certified interior designer provisions directly.
Size and shape
Not addressed from a primary source. No dimension for a New Jersey certified interior designer device could be verified. The sources here are the State Board of Architects home page, its Laws and Regulations page and its Frequently Asked Questions including the full published fee schedule, none of which addresses the credential’s seal.
Embosser, rubber stamp or digital
Not verified. This Board charges a Replacement or Duplicate Seal Press Fee of forty dollars on its architect fee schedule, which shows the Board issuing impression devices to at least one of its credentials. Whether a certified interior designer receives or uses any device could not be confirmed. Do not order anything until the Board confirms what, if any, seal the credential carries.
Signing and dating
Not addressed from a primary source. Any signing and dating duty for a New Jersey Certified Interior Designer sits in N.J.A.C. 13:27. The engineers and land surveyors provisions at N.J.A.C. 13:40-8.1(f) and 13:40-8.3 are a different board’s rules and do not bind this credential.
New Jersey does certify interior designers, and the engineers’ stamp ban has nothing to do with them
The first thing to get right about New Jersey is that the credential exists. The Division of Consumer Affairs maintains an Interior Design Examination and Evaluation Committee among its forty nine professional and occupational boards and committees, and the State Board of Architects handles Certified Interior Designer applications, examinations, complaints, verifications, renewals and reinstatements. That places the credential in N.J.A.C. 13:27.
Which documents must be sealed
Not addressed from a primary source. Which interior design documents, if any, must be sealed in New Jersey sits in N.J.A.C. 13:27. The related statute the Board publishes is the Building Design Services Act, N.J.S.A. 45:4B-1 et seq., which governs who may prepare building design documents in New Jersey and is the instrument that allocates that work among the licensed design professions.
Electronic and digital seals
Not addressed from a primary source. The FIPS PUB 186-4 digital signature and seal standard at N.J.A.C. 13:40-8.1A belongs to the State Board of Professional Engineers and Land Surveyors. Whether the State Board of Architects has adopted any electronic sealing standard for certified interior designers could not be verified, and the Division of Consumer Affairs has been adopting Digital Signature and Seals rules board by board rather than division wide.
Renewal, lapse and retirement
Handled by the State Board of Architects, which states that it manages certified interior designer renewals and reinstatements directly. The architect side of the Board’s fee schedule shows the Board’s general pattern of biennial renewal with a late fee and a reinstatement application fee, and the Board requires documented continuing education for each biennial period during which a license was not active. The certified interior designer specific figures were not verified.
Firm requirements
Not verified. The Board is explicit that architecture and landscape architecture each require their own certificate of authorization from this Board, and that engineering requires a third from the engineers and land surveyors board. Whether a firm offering certified interior design services needs a certificate of authorization was not stated in the Board’s published Frequently Asked Questions and could not be verified.
What to check before you order
Contact the New Jersey State Board of Architects before ordering anything, because the Board handles Certified Interior Designer matters and the codified rules in N.J.A.C. 13:27 are not available except through a portal that requires accepting terms of use or through an unofficial copy the Board flags as possibly not current. Do not buy to the engineers and land surveyors rule: the prohibition on rubber stamp facsimiles and the FIPS PUB 186-4 digital seal standard in N.J.A.C. 13:40 belong to a different board and do not govern you. Note that this Board charges forty dollars for a replacement or duplicate seal press, so if a device is issued to you it is likely to be an impression seal from the Board rather than something you order.

Frequently asked questions
Does New Jersey certify interior designers?
Yes. The Division of Consumer Affairs maintains an Interior Design Examination and Evaluation Committee among its professional and occupational boards and committees, and the State Board of Architects handles Certified Interior Designer applications, examinations, complaints, verifications, renewals and reinstatements. New Jersey is not one of the states that leaves the field entirely unregulated.
Is a seal required for a New Jersey Certified Interior Designer?
That sits in the codified text of N.J.A.C. 13:27, which the Board routes licensees to through a terms-gated portal or an unofficial copy it warns may not be current. Rather than guess, ask the Board directly what the credential requires. Nothing in the Board’s published home page, Laws and Regulations page or Frequently Asked Questions states a seal duty for this credential.
Does the New Jersey rubber stamp ban apply to me?
No. N.J.A.C. 13:40-8.1(a) belongs to the State Board of Professional Engineers and Land Surveyors and binds that board’s licensees. Certified interior designers, architects and landscape architects all sit outside it. That is worth knowing because the ban is widely quoted as if it were a statewide rule for every design profession.
What size would a New Jersey interior designer seal be?
No dimension for the credential appears in anything the Board publishes. Its home page, its Laws and Regulations page and its Frequently Asked Questions, including the full published fee schedule, do not address a seal for this credential. The figure, if there is one, is in N.J.A.C. 13:27.
Would the Board issue me a seal, or would I order one?
Possibly the former. This Board charges a Replacement or Duplicate Seal Press Fee of forty dollars on its architect fee schedule, which shows the Board issuing impression devices to at least one of its credentials. Whether a certified interior designer receives or uses any device is a question for the Board, and it is the reason not to order anything until you have the answer.
What signing and dating rules apply to me in New Jersey?
Any such duty sits in N.J.A.C. 13:27. The provisions at N.J.A.C. 13:40-8.1(f) and 13:40-8.3 are a different board’s rules for engineers and land surveyors and do not bind this credential, so reading them across would be a mistake.
Which New Jersey documents would need sealing?
That also sits in N.J.A.C. 13:27. The related statute the Board publishes is the Building Design Services Act, N.J.S.A. 45:4B-1 et seq., which governs who may prepare building design documents in New Jersey and is the instrument allocating that work among the licensed design professions. It is the right place to start on scope even while the seal question is open.
Is there an electronic sealing standard for New Jersey interior designers?
The FIPS PUB 186-4 digital signature and seal standard at N.J.A.C. 13:40-8.1A belongs to the State Board of Professional Engineers and Land Surveyors. Whether the State Board of Architects has adopted any electronic sealing standard for certified interior designers is a question for the Board, and the Division of Consumer Affairs has been adopting Digital Signature and Seals rules board by board rather than division wide.
How does New Jersey renewal work for this credential?
The State Board of Architects manages certified interior designer renewals and reinstatements directly. The architect side of its fee schedule shows the Board’s general pattern of biennial renewal with a late fee and a reinstatement application fee, and the Board requires documented continuing education for each biennial period during which a license was not active. Confirm the figures for your own credential with the Board.
Does a New Jersey interior design firm need a certificate of authorization?
The Board is explicit that architecture and landscape architecture each require their own certificate of authorization from it, and that engineering requires a third from the engineers and land surveyors board. Whether a firm offering certified interior design services needs one is a question the Board’s published Frequently Asked Questions leave open, so put it to the Board alongside the seal question.
