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 Mississippi board; the profession is unregulated in this state and Mississippi Secretary of State, Mississippi Administrative Code agency listing (no interior design agency under Title 30) on 21 September 2026 · Updated 21 September 2026
Mississippi does not license, register or certify interior designers, so no seal is prescribed for the profession. The Mississippi Secretary of State is the official registrar for state agency rules and publishes the complete agency list for the Mississippi Administrative Code. Under Title 30, Professional and Occupational Licenses, the design and technical agencies are the Board of Licensure for Professional Engineers and Land Surveyors, the State Board of Architecture and the State Board of Geologists. There is no interior design agency and no Title 30 part for it.
With nothing prescribed, nothing is restricted. No diameter, no legend, no artwork, nothing to file. Any device you carry is a business or identification stamp, which makes it a design decision, and 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.
The wording is where Mississippi draws its line. 30 Miss. Admin. Code Pt. 201 reserves the words Registered Architect State of Mississippi to the architect seal, and Miss. Code Ann. § 73-13-29 makes it unlawful for anyone other than the licensee to whom a seal was issued to use it. 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 Mississippi?
Mississippi does not license, register or certify interior designers, and therefore issues no interior designer seal. The Mississippi Secretary of State is the official registrar for state agency rules and publishes the complete agency list for the Mississippi Administrative Code. Under Title 30, Professional and Occupational Licenses, the design and technical agencies are the Board of Licensure for Professional Engineers and Land Surveyors, the State Board of Architecture and the State Board of Geologists. There is no interior design board and no Title 30 part for interior design, no registration number to inscribe and no legend to letter.
What must appear on the seal
- Mississippi licenses no interior designers and issues no interior designer seal
There is nothing to specify. Because Mississippi 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: 30 Miss. Admin. Code Pt. 201 reserves the words Registered Architect State of Mississippi to the architect seal, and Miss. Code Ann. § 73-13-29 makes it unlawful for anyone other than the licensee to whom a seal was issued to use it. A Mississippi interior design device must not read as an architect seal.
Size and shape
No dimension exists. Mississippi prescribes no interior designer seal, so there is no diameter to state. The sources here are the Mississippi Secretary of State’s administrative code agency listing, which names every agency whose rules are filed in the Mississippi Administrative Code, and the three Title 30 design and technical agencies it contains.
Embosser, rubber stamp or digital
Not a regulated purchase. Any device a Mississippi interior designer uses is a business or identification stamp, not a professional seal, and it carries no statutory effect. A Mississippi building official cannot accept an interior designer stamp in place of an architect seal, because 30 Miss. Admin. Code Pt. 201, R. 3.2.4 requires the architect’s stamp with the signature and date of execution over it on documents prepared by the architect or under the architect’s responsible control.
Signing and dating
Not addressed, because Mississippi has no interior design credential to attach a signature duty to. Where a Mississippi project requires sealed documents, the signature and date of execution go over the architect’s stamp under 30 Miss. Admin. Code Pt. 201, R. 3.2.4, or over the landscape architect’s seal under Pt. 202, R. 1.11.3, or with the engineer or surveyor seal under Pt. 901, R. 6.2.
There is no Mississippi interior designer stamp to buy, and that is the answer
The Mississippi Secretary of State publishes the agency list for the Mississippi Administrative Code, and Title 30 contains three design and technical agencies: the Board of Licensure for Professional Engineers and Land Surveyors, the State Board of Architecture and the State Board of Geologists. Interior design is not among them. No board issues a number, no rule sets a legend, and no Mississippi building official is looking for an interior designer seal.
Which documents must be sealed
No Mississippi document requires an interior designer seal. The sealing duty attaches to drawings, specifications and contract documents under the architecture rules, to original sheets of working drawings, project manual cover and index pages and addenda under the landscape architecture rules, and to surveying plats, maps and reports and engineering documents under Miss. Code Ann. § 73-13-29.
Electronic and digital seals
Not applicable. The manual, electronic or digital signature permission at 30 Miss. Admin. Code Pt. 201, R. 3.2.4 attaches to registered architects, and the Board of Licensure for Professional Engineers and Surveyors addresses digital seals and signatures for its own licensees. Mississippi 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. Contrast the Mississippi architect position, where rule 3.4 makes an approved seal imprint a condition of an active license.
Firm requirements
Not applicable. Mississippi registers no interior design firm and issues no certificate of authority for interior design. The certificate of authority Mississippi does issue, under Miss. Code Ann. § 73-13-43, reaches corporations, firms and partnerships practicing professional engineering or professional surveying.
What to check before you order
You do not need, and cannot lawfully obtain, a Mississippi interior designer seal, because Mississippi 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 Registered Architect State of Mississippi, and anything resembling them, off it. If your work is going to a Mississippi building official, the sealed document has to carry the registered architect’s stamp with the signature and date of execution over it, or the seal of the licensed professional engineer or professional surveyor in responsible charge.

Frequently asked questions
Does Mississippi license interior designers?
No. The Mississippi Administrative Code agency listing, which names every agency whose rules are filed with the Secretary of State, shows only three Title 30 design and technical agencies, being the engineers and land surveyors board, the architecture board and the geologists board. Interior design is not among them, so there is no registration number to inscribe and no legend to letter.
Is an interior designer seal required in Mississippi?
No rule requires one and none is prescribed. Mississippi’s sealing duties belong to its three regulated design and technical credentials, at 30 Miss. Admin. Code Pt. 201 for architects, Pt. 202 for landscape architects and Pt. 901 with Miss. Code Ann. § 73-13-29 for engineers and surveyors.
What can I put on a Mississippi 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. With nothing prescribed, the size, shape and layout are yours.
What should I keep off a Mississippi interior designer stamp?
The phrase Registered Architect State of Mississippi, and anything resembling it. That wording is reserved to the architect seal, and Miss. Code Ann. § 73-13-29 makes it unlawful for anyone other than the licensee to whom a seal was issued to use it. A device that reads like a professional seal on a Mississippi drawing invites a complaint even though the work itself is unregulated here.
What size should a Mississippi interior designer stamp be?
Any size. Mississippi prescribes no interior designer seal and therefore no diameter. Nothing in the Secretary of State’s agency listing or the three Title 30 design and technical agencies offers a figure for the profession.
Who seals a Mississippi permit submission?
The architect, engineer or surveyor in responsible charge. 30 Miss. Admin. Code Pt. 201, R. 3.2.4 requires the architect’s stamp with the signature and date of execution over it on documents prepared by the architect or under the architect’s responsible control. The landscape architecture rules put the seal on original sheets of working drawings, project manual cover and index pages and addenda, and Miss. Code Ann. § 73-13-29 covers surveying plats, maps and reports and engineering documents.
Does my out-of-state interior design credential count in Mississippi?
It describes a credential the issuing state grants. A Registered Interior Designer stamp from Alabama, Arkansas, Iowa or Louisiana, and a Certified Interior Designer credential from Kentucky or Maine, all describe real credentials elsewhere and none in Mississippi. Describe any out-of-state credential as that state’s credential rather than leaving the state off.
Can I sign Mississippi interior design documents electronically?
Nothing restricts you. The manual, electronic or digital signature permission at 30 Miss. Admin. Code Pt. 201, R. 3.2.4 attaches to registered architects, and the Board of Licensure for Professional Engineers and Surveyors addresses digital seals and signatures for its own licensees. Mississippi sets no electronic interior designer seal standard, because it sets none for the profession at all.
Does a Mississippi interior design firm need a certificate of authority?
No. The certificate of authority Mississippi does issue, under Miss. Code Ann. § 73-13-43, reaches corporations, firms and partnerships practicing professional engineering or professional surveying. Mississippi registers no interior design firm.
Is there a Mississippi interior design credential to renew?
None. With no credential there is no renewal cycle, no lapse, no number to change and no device to surrender. Contrast the Mississippi architect position, where rule 3.4 makes an approved seal imprint a condition of an active license.
