The Missouri rules in full, with citations

Chapter 3 also contains 20 CSR 2030-3.010, which sets the official seal of the Board itself at two and one-quarter inches. That is the Board's own seal, imprinted on documents the Board issues, not the licensee's seal, and the two are easily conflated because they sit in the same chapter. Missouri uses the title "registered geologist," not "licensed" or "professional" geologist, and the rule's wording tracks that. 20 CSR 2145-2.100 was last amended by a rule filed July 26, 2019, effective January 30, 2020; its authority is § 256.456, RSMo 2016 and § 256.462.3, RSMo Supp. 2019.

"Each registered geologist shall, at his/her own expense, secure a seal or rubber stamp, one and three-quarters inches (1 3/4") in diameter. The seal shall consist of concentric circles between which shall appear in capital letters 'STATE OF MISSOURI' on the upper part of the seal, and 'REGISTERED GEOLOGIST' on the lower part of the seal. Within the inner circle of the seal shall appear the name of the registered geologist in printed letters and his/her certificate number preceded by the capital letters 'RG.'" (20 CSR 2145-2.100(1))
"The seal may be in the form of an embossing seal, a rubber stamp, or a computer-generated image, identical in size or design and content with the provisions of section (1) of this rule." (20 CSR 2145-2.100(2))
"In addition to the personal seal, the registered geologist shall also affix his/her signature on or through his/her seal, and place the date of the signature under the seal on each sheet in a set of plans, drawings, specifications, maps, reports, and other documents which are prepared by the registered geologist or under the registered geologist's immediate personal supervision." (20 CSR 2145-2.100(3))
"When there are multiple page plans, reports, maps, drawings, or other documents or instruments, the registered geologist may sign, seal, and date only the title or index page, providing the signed sheet clearly identifies all of the other pages comprising the bound volume were prepared by him/her or under their immediate personal supervision." (20 CSR 2145-2.100(3)(A))
"When revisions are made, the registered geologist who made the revisions or under whose personal supervision the revisions were made shall place his/her signature on the same line next to the revision date and give an explanation of the revisions." (20 CSR 2145-2.100(3)(B))
Where a document set carries the seals of more than one licensed or registered professional, the registered geologist should certify on the title or index page that his/her seal relates only to the portions involving the practice of geology, and should identify on the title page or index the geologic portions he/she or someone under his/her immediate personal supervision prepared. (20 CSR 2145-2.100(3)(C))
"If two (2) or more registered geologists provide reports, plans, drawings, maps, or other documents, each registrant shall date, sign and seal those documents using the appropriate disclaimer identifying each registrant's responsibility." (20 CSR 2145-2.100(4))
"Any documents not prepared by the registered geologist or under his/her personal supervision shall not be signed or sealed by the registered geologist." (20 CSR 2145-2.100(5))
"Any registered geologist who does not have a current license in this state is prohibited from using his/her seal on any documents until the license is renewed or otherwise reinstated." (20 CSR 2145-2.100(6))
The statute behind the rule requires that geology work affecting public health, safety and welfare be "signed and sealed by the registered geologist in responsible charge," and that geologic reports (or geologic portions of reports) required by municipal, county, state or federal law be prepared by or under the supervision of a registered geologist "as evidenced by the registered geologist's signature and seal." (§ 256.456.1, .2, RSMo)

Missouri Geologist Seal FAQs

Frequently asked questions about Missouri digital geologist stamps and seals.

How do I obtain a digital Missouri professional geologist seal or stamp?

Once you are licensed in Missouri, you can generate your seal here and download it immediately. Fill in the form and position your signature if you want one. The layout follows 20 CSR 2145-2.100; § 256.456, RSMo, which is the provision the Missouri Board of Geologist Registration will measure the seal against.

What are the requirements for the Missouri geologist stamp or seal?

Missouri’s geologist seal rule is 20 CSR 2145-2.100; § 256.456, RSMo, administered by the Missouri Board of Geologist Registration, a different body from the engineering board. The seal must carry “STATE OF MISSOURI, REGISTERED GEOLOGIST”, and one and three-quarters inches (1 3/4") in diameter, prescribed by rule. A computer-generated image must be "identical in size or design and content" with that specification.

A further 10 requirements, each tied to the subsection that imposes it, are itemised in the Missouri requirements section on this page.

What size does a Missouri geologist seal have to be?

One and three-quarters inches (1 3/4") in diameter, prescribed by rule. A computer-generated image must be "identical in size or design and content" with that specification. This is set by 20 CSR 2145-2.100(1), (2).

Is your certificate number preceded by the letters "RG"?

The rule requires the number inside the inner circle to be "preceded by the capital letters 'RG.'" A bare number does not match the prescribed design. (20 CSR 2145-2.100(1))

Is the signature on or through the seal, with the date underneath?

Missouri does not accept a signature merely placed near the seal. Section (3) requires the signature "on or through" the seal and the date of the signature placed under the seal. (20 CSR 2145-2.100(3))

Does a computer-generated seal have to match the embossed one?

Yes. Section (2) permits a computer-generated image only if it is "identical in size or design and content" with the 1 3/4-inch design in section (1). (20 CSR 2145-2.100(2))

Is your seal on a document that also carries other professionals' seals?

The rule directs the registered geologist to certify on the title or index page that his or her seal relates only to the portions involving the practice of geology, and to identify which geologic portions were prepared under his or her immediate personal supervision. (20 CSR 2145-2.100(3)(C))
