Written by Acorn Sales Company, manufacturing stamps and seals since 1964 · Reviewed by Holly R, VP of Sales and Marketing at Acorn Sales, against no Idaho board; the profession is unregulated in this state and Idaho Division of Occupational and Professional Licenses, occupations and professions listing (no interior design program) on 21 September 2026 · Updated 21 September 2026
Idaho does not license, register or certify interior designers, so nothing about your stamp is prescribed. The Idaho Division of Occupational and Professional Licenses administers the state’s occupational boards and publishes the list of professions it covers. Under Building, Construction and Real Estate it lists Architects and Landscape Architects, Professional Engineers and Land Surveyors, and Geologists. Interior design appears neither there nor in the Division’s health or occupational groupings, there is no IDAPA chapter for it, and Idaho Code Title 54 has no interior design chapter.
Which leaves the device entirely to you: no diameter, no legend, no artwork to match, nothing to file. Acorn will make it to whatever you want on it, whether that is your own name, your firm name, a monogram, your logo, or a credential you actually hold such as NCIDQ.
Idaho polices two neighboring titles with unusually broad language, and that is the line to watch. Idaho Code § 54-305 forbids practicing architecture or using the title architect or “any words, letters, figures, title, sign or other device” implying architectural licensure without one, and § 54-3002 does the same for the landscape architect title. Put your own name, your firm name, and any credential you actually hold, such as NCIDQ. Leave off “Licensed” and “Registered” and any state-issued title unless the state issued you one, because that is the part some states do restrict.

Is a seal required in Idaho?
Idaho does not license, register or certify interior designers, and therefore issues no interior designer seal. The Idaho Division of Occupational and Professional Licenses administers the state’s occupational boards and publishes the list of professions it covers; under Building, Construction and Real Estate it lists Architects and Landscape Architects, Professional Engineers and Land Surveyors, and Geologists, and interior design does not appear there or in the Division’s health or occupational groupings. There is no Idaho board, no IDAPA chapter for interior design, no registration number to inscribe and no legend to letter.
What must appear on the seal
- Idaho licenses no interior designers and issues no interior designer seal
There is nothing to specify. Because Idaho grants no interior design credential, no wording is authorized and no wording is prohibited by a licensing board. What is policed is the neighboring title: Idaho Code § 54-305 forbids practicing architecture or using the title architect or “any words, letters, figures, title, sign or other device” implying architectural licensure without one, and § 54-3002 does the same for the landscape architect title. An Idaho interior design device must not drift toward either.
Size and shape
No dimension exists. Idaho prescribes no interior designer seal, so there is no diameter to state. The sources here are the Idaho Division of Occupational and Professional Licenses occupations listing and the Idaho Code Title 54 chapters for the three Idaho design boards: ch. 3 (Architects), ch. 30 (Landscape Architects), ch. 12 (Engineers and Surveyors) and ch. 28 (Geologists).
Embosser, rubber stamp or digital
Not a regulated purchase. Any device an Idaho interior designer uses is a business or identification stamp, not a professional seal, and it carries no statutory effect. An Idaho building official cannot accept an interior designer stamp in place of an architect seal, because Idaho Code § 54-304(3) deems unacceptable any technical submission presented to a governmental agency for a building permit without the architect’s affixed seal, signature and date.
Signing and dating
Not addressed, because Idaho has no interior design credential to attach a signature duty to. Where an Idaho project requires sealed documents, the seal, signature and date obligations belong to the licensed architect under Idaho Code § 54-304(2) or to the licensed professional engineer or land surveyor under § 54-1215(3).
There is no Idaho interior designer stamp to buy, and that is the answer
The Idaho Division of Occupational and Professional Licenses administers the state’s occupational boards, and its building, construction and real estate group lists Architects and Landscape Architects, Professional Engineers and Land Surveyors, and Geologists. Interior design is not among them. There is no IDAPA chapter for it, no board issuing a number, and no Idaho official looking for an interior design seal on a submission.
Which documents must be sealed
No Idaho document requires an interior designer seal. The sealing duty attaches to technical submissions under Idaho Code § 54-304 and to final specifications, land surveys, reports, plats, drawings, plans, design information and calculations under § 54-1215(3)(b), and is discharged by the licensed architect, professional engineer or professional land surveyor in responsible charge. Idaho Code § 54-306 carries the architectural exemptions.
Electronic and digital seals
Not applicable. The manual or electronic application rule at Idaho Code § 54-304(2) attaches to licensed architects, and the rubber stamp, crimp or electronically generated image provision at § 54-1215(3)(a) attaches to engineers and land surveyors. Idaho has no interior design credential and therefore no electronic interior designer seal standard.
Renewal, lapse and retirement
Not applicable. With no credential there is no renewal cycle, no lapse, no number to change and no device to surrender.
Firm requirements
Not applicable. Idaho registers no interior design firm and issues no certificate of authorization for interior design. The certificate of authorization Idaho does issue, under Idaho Code § 54-1235, reaches only engineering and land surveying entities, and it comes with a Secretary of State name filter on the words engineer, engineering, land surveyor and land surveying.
What to check before you order
You do not need, and cannot lawfully obtain, an Idaho interior designer seal, because Idaho does not license or register the profession. If you want a device for your own drawings, order a plain identification stamp with your name and firm, and describe any out-of-state credential as that state’s credential. Keep the words architect and landscape architect off it, because Idaho Code §§ 54-305 and 54-3002 restrict those titles and any device implying them. If your work is going to an Idaho building department for a permit, the submission has to carry the licensed architect’s seal, signature and date, or it is deemed unacceptable under Idaho Code § 54-304(3).

Frequently asked questions
Does Idaho license interior designers?
No. The Idaho Division of Occupational and Professional Licenses occupations and professions listing has no interior design program, and Idaho Code Title 54 has no interior design chapter. Interior design practice in Idaho is open, so there is no number for a stamp to carry.
Is an interior designer seal required in Idaho?
No rule requires one and none is prescribed. Idaho’s sealing duties belong to the credentials it issues: Idaho Code § 54-304(2) for licensed architects and § 54-1215(3) for licensed professional engineers and land surveyors. Whether you carry a stamp at all is up to you.
What can I put on an Idaho interior designer stamp?
Anything true about you: your name, your firm name, a monogram, your logo, contact details, or the exact name of a private certification such as the NCIDQ certificate from the Council for Interior Design Qualification. A plain identification stamp is the honest device, and its size and shape are yours to pick.
What should an Idaho interior designer stamp avoid?
The words architect and landscape architect, and anything that implies either. Idaho Code § 54-305 is drafted broadly enough to cover “any words, letters, figures, title, sign or other device” implying architectural licensure, and § 54-3002 restricts the landscape architect title. A stamp that reads close to those words on an Idaho drawing invites a complaint even though the interior design work itself is unregulated.
What size should an Idaho interior designer stamp be?
Any size. Idaho prescribes no interior designer seal and therefore no diameter. Neither the Division’s occupations listing nor the Title 54 chapters for the Idaho design boards, at ch. 3 for architects, ch. 30 for landscape architects, ch. 12 for engineers and surveyors and ch. 28 for geologists, offers a figure for the profession.
Will an Idaho building official accept my stamp?
Not in place of an architect’s. Idaho Code § 54-304(3) deems unacceptable any technical submission presented to a governmental agency for a building permit without the architect’s affixed seal, signature and date. Idaho Code § 54-306 carries the architectural exemptions, which is where to look before assuming a seal is needed at all.
Which Idaho documents need a seal, and whose?
Technical submissions under Idaho Code § 54-304 and final specifications, land surveys, reports, plats, drawings, plans, design information and calculations under § 54-1215(3)(b), discharged by the licensed architect, professional engineer or professional land surveyor in responsible charge. No Idaho document requires an interior designer seal.
Does my out-of-state interior design credential count in Idaho?
It describes a credential the issuing state grants. A Registered Interior Designer stamp from Alabama, Arkansas or Iowa, a Certified Interior Designer certificate from Kentucky or Maine, and a Registered Interior Designer seal from Louisiana all describe real credentials elsewhere and none in Idaho. If you want yours visible, name the issuing state expressly.
Can I sign Idaho interior design documents electronically?
Nothing restricts you. The manual or electronic application rule at Idaho Code § 54-304(2) attaches to licensed architects, and the rubber stamp, crimp or electronically generated image provision at § 54-1215(3)(a) attaches to engineers and land surveyors. Idaho has no interior design credential and therefore no electronic interior designer seal standard.
Does an Idaho interior design firm need a certificate of authorization?
No. The certificate of authorization Idaho does issue, under Idaho Code § 54-1235, reaches only engineering and land surveying entities, and it comes with a Secretary of State name filter on the words engineer, engineering, land surveyor and land surveying. An interior design firm in Idaho holds no board credential and no firm seal.
