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 Oregon board licenses this profession and Oregon Secretary of State Administrative Rules, chapter index (no interior design chapter) on 21 September 2026 · Updated 21 September 2026
Oregon does not license, register or certify interior designers, so there is no Oregon interior design stamp to get right. The Oregon Administrative Rules chapter index carries a chapter for every regulatory board that touches design work: chapter 804 for the Landscape Architect Board, chapter 806 for the State Board of Architect Examiners, chapter 809 for the Board of Geologist Examiners and chapter 820 for the Board of Examiners for Engineering and Land Surveying. Each of those chapters carries a detailed stamp specification. There is no chapter for interior design, no board, and ORS ch. 671 creates no interior design credential.
Nothing is prescribed, so the design is yours. One limit still applies, and it is about wording rather than shape. No diameter, no legend, no approved artwork, no required device and no imprint to file with anyone. What you carry on a stamp in Oregon is a design decision rather than a compliance one, and Acorn will cut it to whatever you want: your own name, your firm name, a monogram, your logo, or a credential you actually hold such as NCIDQ.
The line to stay on the right side of is the wording. 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 Oregon?
Oregon does not license, register or certify interior designers, and therefore issues no interior design seal or stamp. The Oregon Administrative Rules chapter index carries a chapter for each regulatory board, including chapter 804 for the Landscape Architect Board, chapter 806 for the State Board of Architect Examiners, chapter 809 for the Board of Geologist Examiners and chapter 820 for the Board of Examiners for Engineering and Land Surveying. There is no chapter for interior design and no interior design board in the index. ORS ch. 671, which creates the architect and landscape architect credentials, creates no interior design credential.
What must appear on the seal
- Not applicable: Oregon issues no interior design seal
There is no Oregon interior design seal to specify, because Oregon creates no interior design credential. Two honest alternatives exist. A private credential such as the NCIDQ certificate may be named in a text block, but it is not an Oregon registration and must not be presented in a way that suggests one. Registration in a state that does license or certify interior designers authorizes a seal for that state only. Work in Oregon that amounts to the practice of architecture has to be stamped by an Oregon registered architect under OAR 806-010-0045, and OAR 806-010-0001(5)(c) makes the point expressly by naming architectural drawings and technical submissions for non exempt work as requiring an Oregon registered architect’s stamp and signature.
Size and shape
Not applicable. No Oregon statute or administrative rule prescribes an interior design seal, because no Oregon board issues an interior design credential. Checked the Oregon Administrative Rules chapter index for any interior design chapter, OAR chapter 806 division 10 and division 20 for the architect board, and OAR chapter 804 for the landscape architect board.
Embosser, rubber stamp or digital
Not applicable. Oregon authorizes crimp, rubber style and computer-generated stamps at OAR 806-010-0045(2) for architects and at OAR 804-030-0000(1) for landscape architects. No device is authorized for an interior designer because Oregon issues no interior design credential to put on one.
Signing and dating
Not applicable. OAR 806-010-0045(6) requires an architect’s signature to be placed across the architect’s stamp, and OAR 804-030-0003 requires a landscape architect to sign across the landscape architect’s stamp. Neither reaches interior designers. An interior designer practicing in Oregon signs as an unlicensed professional and should add no legend or number that implies a state credential.
Oregon regulates four design professions and interior design is not one of them
Oregon gives architects, landscape architects, geologists and the engineering and surveying credentials each their own board and their own administrative rules chapter, and each of those chapters carries a detailed stamp specification. Interior design has none of that. There is no chapter in the Oregon Administrative Rules index, no board, no registration and therefore no authorized stamp design, no prescribed diameter and no legend.
The practical risk runs the same way it does in every unregulated state. Nothing physically prevents a supplier from cutting a round die that reads INTERIOR DESIGNER and STATE OF OREGON with a number in the middle. Using it does not give it legal force, and it invites a complaint, because a device that implies a state registration nobody issues is a misrepresentation whatever the intention behind it.
The other half of the answer is more useful. OAR 806-010-0045(7) requires an Oregon registered architect’s stamp on every sheet of drawings intended for permit or construction “whether or not the project is exempt under ORS 671.030,” and OAR 806-010-0001(5)(c) treats technical submissions for non exempt work as requiring one. So for interior work that reaches into the practice of architecture, the question is never which stamp you buy; it is which Oregon registered architect takes responsible control and stamps the set.
Which documents must be sealed
Not applicable to an interior designer directly. The live question in Oregon is which interior work needs an architect’s stamp. OAR 806-010-0045(3) requires all technical submissions required by public authorities for building permits or regulatory approvals, or intended for construction purposes, to be stamped and signed by an architect, and OAR 806-010-0045(7) applies that “whether or not the project is exempt under ORS 671.030.” Interior work that stays outside the practice of architecture as OAR 806-010-0001 defines it needs no stamp from anyone.
Electronic and digital seals
Not applicable. Oregon’s electronic signing rules attach to credentials it issues: OAR 806-010-0045(6) for architects, OAR 804-030-0003 for landscape architects, OAR 809-050-0005 for geologists and OAR 820-025-0010 for engineers and land surveyors. None of them reaches interior designers, and Oregon sets no electronic signing standard for a profession it does not regulate.
Renewal, lapse and retirement
Not applicable. There is no Oregon interior design registration to renew, lapse, restore or revoke, and no registration number that could change. A private certification such as NCIDQ is governed by the issuing organization rather than by Oregon.
Firm requirements
Not applicable. Oregon registers architectural firms under OAR 806-010-0080 and landscape architecture businesses under OAR 804-035-0010, but neither scheme reaches interior design and no board registers an interior design business. An Oregon interior design firm holds no board registration and no seal. A firm that also offers architecture triggers the architectural firm registration requirement on its own terms.
What to check before you order
Do not order an Oregon interior design stamp. There is no Oregon credential for one to represent, and a round die carrying the state name and a number will read as a claim to a registration that does not exist. If you want a professional identifier for your drawings, ask for a rectangular text block with your name, your firm and the exact name of any private certification you hold, with no circle, no state name and no license-style number. When a project reaches into the practice of architecture, the sheets need an Oregon registered architect’s stamp under OAR 806-010-0045, and no interior design credential from any source substitutes for it.

Frequently asked questions
Does Oregon license or register interior designers?
No. The Oregon Administrative Rules chapter index lists a chapter for each regulatory board, and there is no interior design chapter and no interior design board in it. ORS ch. 671, which creates the architect and landscape architect credentials, creates no interior design credential either. Interior design practice in Oregon is open, which is why there is no registration number for a stamp to carry.
Is an interior designer seal required in Oregon?
No Oregon rule requires one, prohibits one or describes one. The stamp rules in the state belong to the credentials Oregon issues: OAR 806-010-0045 for architects, OAR 804-030-0000 for landscape architects, OAR 809-050-0005 for geologists and OAR 820-025-0010 for engineers and land surveyors. None of them reaches interior designers. Whether you own a stamp at all is up to you.
What can go on an interior designer stamp in Oregon?
Anything true about you. Your name, your firm, a monogram, a logo, your contact details, or the exact name of a private certification such as the NCIDQ certificate from the Council for Interior Design Qualification. Because no Oregon rule prescribes a layout, the shape is open too, and a rectangular text block often reads better on a drawing sheet than a circle does.
What should I keep off an Oregon interior designer stamp?
Anything that reads as an Oregon registration. That means no STATE OF OREGON set in a ring, no bare word “Registered” and no license-style number sitting on its own in the middle. A round die reading INTERIOR DESIGNER and STATE OF OREGON with a number in it asserts a registration the state does not issue, whatever the intention behind it. Naming NCIDQ in plain words is a different matter and is accurate.
What size should an Oregon interior designer stamp be?
Whatever suits the sheet. No Oregon statute or administrative rule prescribes a size, because no Oregon board issues the credential. For reference, the sizes Oregon does prescribe belong to other professions entirely and have no bearing on you. Round dies in the 1-1/2 to 2 inch range and rectangular blocks around 2-1/2 by 1 inch are the two shapes that tend to sit well in a title block.
Rubber stamp, embosser or digital file?
All three are open to you, and none is required. Oregon authorizes crimp, rubber style and computer-generated stamps at OAR 806-010-0045(2) for architects and at OAR 804-030-0000(1) for landscape architects, but those provisions govern credentials you do not hold. An inked stamp is the most useful object in practice, since it reproduces through scanning and copying; an embosser is the nicer object on a presentation cover.
Who stamps an Oregon interior project that needs a permit?
An Oregon registered architect, where the work amounts to the practice of architecture. OAR 806-010-0045(3) requires all technical submissions required by public authorities for building permits or regulatory approvals, or intended for construction purposes, to be stamped and signed by an architect, and OAR 806-010-0045(7) applies that “whether or not the project is exempt under ORS 671.030.” OAR 806-010-0001(5)(c) makes the same point about technical submissions for non exempt work. Interior work that stays outside the practice of architecture as OAR 806-010-0001 defines it needs no stamp from anyone.
Does an NCIDQ certificate let me stamp drawings in Oregon?
It gives you something true to put on a stamp, not authority to stamp. NCIDQ is a private examination credential rather than an Oregon registration, and Oregon grants no practice authority on the strength of it. Name it precisely in a text block, and do not compress it into a circular device that could be read as a state seal.
Can I sign Oregon interior design documents electronically?
Nothing restricts you, because nothing regulates you here. Oregon’s electronic signing rules attach to credentials it issues, at OAR 806-010-0045(6) for architects, OAR 804-030-0003 for landscape architects and OAR 820-025-0010 for engineers and land surveyors. Oregon sets no electronic signing standard for interior designers because it sets no signing standard for them at all, so a stamp image in a PDF beside your signature is a business choice.
Does an Oregon interior design firm need to register with a board?
No. Oregon registers architectural firms under OAR 806-010-0080 and landscape architecture businesses under OAR 804-035-0010, and neither scheme reaches interior design. An Oregon interior design firm holds no board registration and no firm seal. A practice that also offers architecture triggers architectural firm registration on its own terms.
