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 board: Guam does not register or license interior designers and 22 GCA ch. 32, §§ 32103, 32116(d) (no mention of interior designers) on 21 September 2026 · Updated 21 September 2026
Guam registers four design professions and interior design is not one of them. 22 GCA ch. 32, the Professional Engineers, Architects and Land Surveyors Law, names its subjects precisely: professional engineers, registered architects, registered landscape architects and professional land surveyors. Landscape architecture being in surprises people. Interior design is not mentioned in the chapter at any point, including the definitions at § 32103 and the seal section at § 32116(d), so there is no credential to seal with.
Nothing is prescribed, so the design is yours. One limit still applies, and it is about wording rather than shape. No element list governs your device, no board approves a design, and there is no dimension to match. Acorn will make it to whatever you want on it: your own name, your firm name, a monogram, your logo, or a credential you actually hold such as NCIDQ.
One block to stay away from, and it is a sentence rather than a shape. A device that pairs a professional designation and a registration number with the statutory certification sentence, This work was prepared by me or under my responsible control, is the visual signature of a Guam registrant’s seal block, and there is no interior design registration number to stand behind it. Put your own name, your firm name, and any credential you actually hold, such as NCIDQ. Leave off “Licensed” and “Registered” and any government-issued title unless the jurisdiction issued you one, because that is the part some places do restrict.

Is a seal required in Guam?
Guam does not register, license or certify interior designers, and no Guam agency issues an interior designer’s seal. The Professional Engineers, Architects and Land Surveyors Law at 22 GCA ch. 32 registers four professions, professional engineers, registered architects, registered landscape architects and professional land surveyors, and the chapter does not mention interior designers at any point, including in the definitions at § 32103 and the seal section at § 32116(d). There is no credential to seal with.
What must appear on the seal
- Not applicable: Guam issues no interior design credential and prescribes no interior designer seal
Nothing is prescribed because nothing is regulated. An interior designer working on Guam may use a firm stamp or a logo device, and no Guam element list governs it. What to avoid is a die that pairs a professional designation and a registration number with the certification sentence the statute prescribes, This work was prepared by me or under my responsible control. That sentence is the visual signature of a Guam registrant’s seal block and there is no interior design registration number to stand behind it.
Size and shape
Not applicable. Guam prescribes no interior designer seal and therefore no dimension. The sources here are 22 GCA ch. 32 §§ 32103 and 32116(d) and found no reference to interior designers.
Embosser, rubber stamp or digital
Not applicable. With no Guam interior design credential there is no required instrument. Where interior work forms part of a Guam permit submittal, the seal on it is the registered architect’s under 22 GCA § 32116(d)(9) or a professional engineer’s of the appropriate branch under (d)(9)(C).
Signing and dating
Not applicable. No Guam law prescribes a signature or date for an interior designer, because no Guam law prescribes an interior designer seal.
Four professions on one board, and interior design is not among them
22 GCA ch. 32 is the whole design-profession regime on Guam, and it names its subjects precisely: professional engineers, registered architects, registered landscape architects and professional land surveyors. Landscape architecture is in, which surprises people. Interior design is not mentioned in the chapter at all, not in the definitions at § 32103 and not in the seal section at § 32116(d).
Which documents must be sealed
No Guam document requires an interior designer’s seal. Interior design content reaching a permit submittal travels under an architect’s seal, and § 32116(d)(9)(A) reaches all technical submissions such as drawings, specifications, plans, reports or other documents prepared by the registered architect or under the architect’s responsible control.
Electronic and digital seals
Not applicable. No electronic seal standard exists for a profession the territory does not regulate. Note that Guam refuses computer-generated signatures and dates even for the professions it does register, so an electronic workflow is constrained on the island regardless.
Renewal, lapse and retirement
Not applicable. There is no Guam interior design credential to renew, lapse, retire or revoke.
Firm requirements
Not applicable. Guam registers no interior design firms and issues no certificate of authorization for interior design services.
What to check before you order
There is nothing for a Guam interior designer seal to comply with, because the territory registers no interior designers. Do not order a device that pairs a professional designation and a registration number with the statutory sentence This work was prepared by me or under my responsible control; that block belongs to the four professions 22 GCA ch. 32 registers. A firm name plate or a logo device raises none of those questions. If you hold an interior design credential from a jurisdiction that does issue one, order that jurisdiction’s device to its own specification and use it only for work there.

Frequently asked questions
Does Guam register interior designers?
No. 22 GCA ch. 32 is the whole design-profession regime on Guam and it registers professional engineers, registered architects, registered landscape architects and professional land surveyors. Interior design appears nowhere in the chapter.
Is an interior designer seal required on Guam?
No. With no Guam interior design credential there is no required instrument and no document that calls for one. Any device you carry is a firm stamp or a logo device.
What can I put on an interior designer stamp on Guam?
Your name, your firm name, a logo, contact details, or the exact name of a private certification such as the NCIDQ certificate from the Council for Interior Design Qualification. No Guam element list governs it, so the format is yours.
What should a Guam interior designer stamp avoid?
The registrant seal block: a professional designation and a registration number set with the statutory sentence This work was prepared by me or under my responsible control. That block belongs to the four professions 22 GCA ch. 32 registers.
What size should a Guam interior designer stamp be?
Any size. Guam prescribes no interior designer seal and therefore no dimension, and §§ 32103 and 32116(d) contain no reference to interior designers.
Who seals interior drawings in a Guam permit submittal?
The registered architect under 22 GCA § 32116(d)(9), or a professional engineer of the appropriate branch under (d)(9)(C). Section 32116(d)(9)(A) reaches all technical submissions such as drawings, specifications, plans, reports or other documents prepared by the registered architect or under the architect’s responsible control.
Are there Guam rules for residential work worth knowing?
Yes, and they are unusual. For an individual single family dwelling the seal of either an architect or a civil engineer suffices, and for two family dwellings or a subdivision of single and two family dwellings the civil engineer’s seal alone suffices. That allocation shapes who you work with on a residential job.
Can documents be sealed electronically on Guam?
No electronic seal standard exists for a profession the territory does not regulate, and the constraint runs wider than that: Guam refuses computer-generated signatures and dates even for the professions it does register, so an electronic workflow is limited on the island regardless.
What if I hold an interior design credential from elsewhere?
Order that jurisdiction’s device to its own specification and use it only for work there. It describes a credential that jurisdiction grants and nothing that Guam issues.
Does a Guam interior design firm register?
No. Guam registers no interior design firms and issues no certificate of authorization for interior design services, and there is no renewal cycle, no lapse and no device to surrender.
