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 Board of Governors of the Licensed Architects, Landscape Architects and Licensed Interior Designers of Oklahoma and 59 Okla. Stat. § 46.25 on 21 September 2026 · Updated 21 September 2026
Oklahoma defines the instrument by what it must reproduce. OAC 55:10-11-8(a)(1) is a specification rather than a list: the seal “shall be of a type that makes an image on the surface of original documents and duplications of original documents. Both the use of a rubber stamp or electronic image is permissible.” Two devices are named as permissible and a functional test governs.
An embosser appears nowhere in the rule. It is not accurate to say Oklahoma bans embossers: the regulation does not address owning one or using one alongside a compliant stamp. What is accurate is narrower and more useful. A dry embossed impression does not make an image on duplications of original documents, so it cannot serve as the seal this rule requires. If you want a raised device for firm tradition, keep the required elements off it and use a firm name or a neutral design, so nobody can mistake it for the instrument the rule prescribes.
There is no Oklahoma diameter for this board. The statute and the rule describe a circle and its contents and stop, which is the opposite of the Oklahoma engineering and land surveying board next door, whose rule names a one and seven-eighths inch seal and a one and five-eighths inch seal with specified inner circles. Size yours for legibility, and leave room to write a date across the face, because OAC 55:10-11-8(c) puts the date there.

Is a seal required in Oklahoma?
The statute requires the seal to exist and the rule requires it to be used. 59 O.S. § 46.25 provides that “Each architect shall have a seal, the image of which must contain the name of the architect, the person’s license number and the words ‘Licensed Architect, State of Oklahoma’,” and requires all technical submissions prepared by the architect or under the architect’s responsible control to be sealed, signed and dated. OAC 55:10-11-8(a) puts the duty on every licensee to “procure a seal with which to identify all technical submissions, addenda, field orders and other documents of service issued by the Licensee for use in this State.”
What must appear on the seal
- Your name
- Your Oklahoma license number
- The words Licensed Architect, State of Oklahoma
- A circle
The legend is fixed by both statute and rule in the same words, Licensed Architect, State of Oklahoma, and the shape is fixed as a circle. Nothing else is provided for: no firm name, no certificate of authority number on the face, no expiration date, no NCARB number. Note the 2026 statutory relabeling of the board’s third profession from registered to licensed interior designer; if you hold that credential as well you need a separate die, because each legend names one profession. Do not borrow the Oklahoma engineering and surveying artwork from OAC 245:15-17-1(c), which is a two-circle design at named commercial sizes and belongs to a different board.
Size and shape
No size is stated. OAC 55:10-11-8(a)(2) requires a circle and lists the contents, and neither the rule nor 59 O.S. § 46.25 gives a diameter, an inner circle or a lettering height. The sources here are 55:10-11-8 in full and the statutory seal sections at §§ 46.25, 46.34 and 46.42. This is a genuine difference from the Oklahoma engineering board, whose rule at OAC 245:15-17-1(c) names a one and seven-eighths inch and a one and five-eighths inch seal with specified inner circles.
Embosser, rubber stamp or digital
The rule specifies the required instrument by what it must do. OAC 55:10-11-8(a)(1): “The seal required shall be of a type that makes an image on the surface of original documents and duplications of original documents. Both the use of a rubber stamp or electronic image is permissible.” Two devices are named as permissible and a functional test governs. An embosser is not mentioned at all. The rule neither permits nor forbids owning or using one, but a dry embossed impression does not make an image on duplications of original documents, so it cannot meet the specification for the instrument the rule requires. The safe buy is a rubber or self-inking stamp.
Signing and dating
Seal, signature and date on the same documents, with the date across the seal. OAC 55:10-11-8(c) is headed location of seal, signature and date and provides that “The handwritten or electronically generated date shall be affixed across their seal,” and (c)(1) requires all licensees to “affix their seal, signature and date, to all technical submissions and to the original cover sheet and the page identifying all specification pages covered, including all addenda and field changes.” A handwritten date and an electronically generated date are equally acceptable.
The rule defines the instrument by what it must reproduce, and never mentions an embosser
OAC 55:10-11-8(a)(1) is a specification, not a list: the seal “shall be of a type that makes an image on the surface of original documents and duplications of original documents.” Then it names two devices that qualify, a rubber stamp and an electronic image. An embosser appears nowhere in the rule. The regulation does not address owning one or using one alongside a compliant stamp, and it is not accurate to say Oklahoma bans embossers. What is accurate is narrower and more useful: a dry embossed impression does not make an image on duplications of original documents, so it cannot serve as the seal this rule requires. If you want a raised device for firm tradition, keep the required elements off it and use a firm name or a neutral design, so that nobody can mistake it for the instrument the rule prescribes.
Which documents must be sealed
All technical submissions, addenda, field orders and other documents of service issued by the licensee for use in Oklahoma, plus the original cover sheet and the page identifying all specification pages covered. The responsibility limit is statutory: § 46.25 bars an architect from sealing work unless it was “prepared by or under the responsible control of the architect,” with a limited allowance for signing coordinated portions prepared by other licensed professionals. There is no preliminary or draft carve-out written into 55:10-11-8, so anything issued as a document of service is caught.
Electronic and digital seals
An electronic image of the seal is permissible as a device, and an electronically generated date is permissible alongside it. OAC 55:10-11-8(a)(1) names the electronic image as one of the two acceptable forms, and (c) accepts a handwritten or electronically generated date. Beyond that the rule names no certificate authority, no cryptographic standard and no authentication procedure. The sources here are 55:10-11-8 in full. Confirm the acceptable electronic format with the authority having jurisdiction.
Renewal, lapse and retirement
Not addressed in the seal rule. OAC 55:10-11-8 says nothing about what becomes of the seal on expiration, lapse, retirement or revocation, and nothing about whether a license number is reissued. Because the legend certifies current licensure and the number is cut into the die, treat a lapse as making the device unusable. Renewal, reinstatement and discipline sit in the Oklahoma State Architectural and Licensed Interior Designers Act and elsewhere in OAC title 55 chapter 10.
Firm requirements
A Certificate of Authority is required for the entity, and the individual seal still does the work on the document. OAC 55:10-13-5 requires a Certificate of Authority for any firm or entity to contract for or offer licensed services in Oklahoma, and 59 O.S. § 46.9 governs practice through entities, requiring that one or more of the directors, partners, officers, shareholders, managers, members or principals be duly licensed and that the entity obtain Board certification. The firm gets no seal of its own, and neither the statute nor 55:10-11-8 puts the Certificate of Authority number on the face of a sealed document.
What to check before you order
Order a circular stamp carrying your name, your Oklahoma license number and the words Licensed Architect, State of Oklahoma. There is no prescribed diameter in Oklahoma for this board, so size it for legibility and leave room to write a date across the face, which the rule requires. Buy a rubber or self-inking stamp: the rule requires a seal of a type that makes an image on original documents and on duplications of them, and names the rubber stamp and the electronic image as the permissible forms. An embosser is not addressed by the rule and a dry impression will not satisfy the reproduction test, so do not order one as your legal seal. Seal, sign and date all technical submissions, the original cover sheet, the page identifying all specification pages covered, and every addendum and field change.

Frequently asked questions
Is an architect seal required in Oklahoma?
Yes. 59 O.S. § 46.25 provides that “Each architect shall have a seal, the image of which must contain the name of the architect, the person’s license number and the words ‘Licensed Architect, State of Oklahoma’,” and requires all technical submissions prepared by the architect or under the architect’s responsible control to be sealed, signed and dated. OAC 55:10-11-8(a) puts the duty on every licensee to “procure a seal with which to identify all technical submissions, addenda, field orders and other documents of service issued by the Licensee for use in this State.”
What has to appear on an Oklahoma architect seal?
Your name, your Oklahoma license number and the words Licensed Architect, State of Oklahoma, on a circle. The legend is fixed by both statute and rule in the same words, and the shape is fixed as a circle. Nothing else is provided for: no firm name, no certificate of authority number on the face, no expiration date, no NCARB number.
What size is an Oklahoma architect seal?
No size is stated. OAC 55:10-11-8(a)(2) requires a circle and lists the contents, and neither the rule nor 59 O.S. § 46.25 gives a diameter, an inner circle or a lettering height. Rule 55:10-11-8 in full and the statutory seal sections at §§ 46.25, 46.34 and 46.42 read the same way. The Oklahoma engineering board is different, naming a one and seven-eighths inch and a one and five-eighths inch seal at OAC 245:15-17-1(c).
Can an Oklahoma architect use an embosser?
Not as the required seal. The rule requires a seal of a type that makes an image on original documents and on duplications of them, and names the rubber stamp and the electronic image as the permissible forms. A dry embossed impression does not meet the reproduction test. What the rule does not do is address owning an embosser or using one beside a compliant stamp, and that silence is not permission. If you want a raised device, keep the required elements off it so it cannot be taken for the seal the rule prescribes.
Where does the date go on an Oklahoma seal?
Across the seal. OAC 55:10-11-8(c), headed location of seal, signature and date, provides that “The handwritten or electronically generated date shall be affixed across their seal,” so a handwritten date and an electronically generated date are equally acceptable. Leave room on the die for it.
Which documents have to be sealed in Oklahoma?
OAC 55:10-11-8(c)(1) requires all licensees to “affix their seal, signature and date, to all technical submissions and to the original cover sheet and the page identifying all specification pages covered, including all addenda and field changes.” There is no preliminary or draft carve-out in 55:10-11-8, so anything issued as a document of service is caught.
Can I seal work someone else prepared in Oklahoma?
The limit is statutory. Section 46.25 bars an architect from sealing work unless it was “prepared by or under the responsible control of the architect,” with a limited allowance for signing coordinated portions prepared by other licensed professionals.
Can I use an electronic seal in Oklahoma?
Yes. OAC 55:10-11-8(a)(1) names the electronic image as one of the two acceptable forms, and (c) accepts a handwritten or electronically generated date. Beyond that the rule names no certificate authority, no cryptographic standard and no authentication procedure across 55:10-11-8 in full. Confirm the acceptable electronic format with the authority having jurisdiction.
What happens to my Oklahoma seal if my license lapses?
The seal rule does not say. OAC 55:10-11-8 says nothing about what becomes of the seal on expiration, lapse, retirement or revocation, and nothing about whether a license number is reissued. Because the legend certifies current licensure and the number is cut into the die, treat a lapse as making the device unusable. Renewal, reinstatement and discipline sit in the Oklahoma State Architectural and Licensed Interior Designers Act and elsewhere in OAC title 55 chapter 10.
Does an Oklahoma architecture firm get its own seal?
No, though it does need a Certificate of Authority. OAC 55:10-13-5 requires one for any firm or entity to contract for or offer licensed services in Oklahoma, and 59 O.S. § 46.9 governs practice through entities, requiring that one or more of the directors, partners, officers, shareholders, managers, members or principals be duly licensed and that the entity obtain Board certification. The firm gets no seal of its own, and neither the statute nor 55:10-11-8 puts the Certificate of Authority number on the face of a sealed document.
I also hold Oklahoma interior design licensure. Can one seal cover both?
No. Each legend names one profession, so a second credential needs a second die. Note also the 2026 statutory relabeling of the board’s third profession from registered to licensed interior designer. Do not borrow the Oklahoma engineering and surveying artwork from OAC 245:15-17-1(c) either; that is a two-circle design at named commercial sizes and belongs to a different board.
