A Mississippi registered professional geologist must sign, seal and date each sheet of geologic work with the seal the Board adopts for registrants, placed near your typeset name, which is followed by a comma, one space and RPG without periods. No size is stated. The rules name no device. This page covers the seal, the name line, review wording, large print runs and lapse.

Do Mississippi geologists need a seal?
Yes. Rule 1.15 of 30 Miss. Admin. Code Pt. 1101 has the Board adopt a seal for the registrants on its roster, and Rule 10.1 requires every sheet to carry that seal together with your signature and the date.
Rule 10.1 treats those three marks as one certification, so a sheet missing any of them is not certified. For how other states set their geologist seal rules, see our geologist seal rules across all 54 jurisdictions.
What does the Mississippi geologist seal show?
The design the Board adopts. Rule 1.15 puts the design in the Board's hands, and the Part 1101 rules that follow deal with use and placement on the document rather than listing words for the face of the seal.
Before ordering, get the adopted artwork from your licensing board (Mississippi State Board of Registered Professional Geologists). Mississippi's other design boards set their own face and size rules, described on our pages about the Mississippi engineer seal legend and size range and the Mississippi architect stamp. None of those rules applies to an RPG.
What size and shape does the rule require?
None at all. Rule 1.15 and Rules 10.1 to 10.5 give no diameter, no shape and no proportion for a registrant's seal, so the dimensions follow whatever design the Board has adopted.
A figure published for Mississippi engineers, surveyors, architects or landscape architects belongs to that board, so do not borrow one to fill the gap. Our page on the Mississippi landscape architect seal shows how another board sets its own size.
Which device should carry the seal?
The rules leave that to you. Part 1101 talks about signing, sealing and dating and names no embosser, no rubber stamp and no computer generated seal, so the choice of device is yours.
On maps, illustrations, reports and bulletins, Rules 10.3 and 10.4 place the seal beside your typeset name, so choose a device that prints cleanly in that spot. A notary commission, if you hold one, carries its own stamp rules; see our page on Mississippi notary stamp rules.
How should your name appear on maps and reports?
RPG, with no periods, comes after your typeset name, a comma and one blank space. Maps and illustrations take this format under Rule 10.3, and reports and bulletins take it under Rule 10.4.
The seal then sits near that typeset name. This is a rule about the document rather than the face of the seal, so build it into your title block and your report signature page. Written out, it looks like this: Jordan Smith, RPG.
Who may sign, seal and date a sheet?
Rule 10.1 lets three registrants seal: whoever prepared the sheet, whoever had direct supervisory control over its preparation, or one who reviewed it in sufficient depth.
The duty runs sheet by sheet. A set of maps or a bound report carries the certification on each sheet unless the large print concession in Rule 10.5 applies.
What wording goes with a review certification?
A prescribed sentence. Rule 10.2 supplies the wording when a geologic study or project is certified based on review: you state that your review went in sufficient depth to accept full responsibility, and that responsibility covers what the document contains.
Take the exact sentence from Rule 10.2 rather than composing your own version, and include it whenever you certify work on the basis of review.
How do the rules sort geologic work products?
By document type. The rules reach geologic work products in general, naming reports, maps, cross sections, drawings, charts, graphs, descriptions, illustrations and bulletins, then sort them into groups. Rule 10.3 handles maps and illustrations, Rule 10.4 handles reports and bulletins, and Rule 10.5 handles pamphlets and open file reports.
Each group carries the same core certification of seal, signature and date. Maps, illustrations, reports and bulletins all place the seal near the typeset name, and the last group differs in how often the certification has to appear.
How do large print runs meet the rule?
Through a certification page. Rule 10.5 lets pamphlets and open file reports that are reproduced in large numbers carry one page bearing your signature, date and seal, rather than certifying each sheet of every copy.
The concession is narrow. It covers those two document types in quantity, and the sheet by sheet duty in Rule 10.1 still governs the rest of your work.
Is there any electronic sealing rule for Mississippi RPGs?
Part 1101 does not address one. There is no provision for an electronic or digital geologist seal in those rules, and no technology, certificate authority or means of verification is named anywhere in the part.
Electronic provisions do exist for other Mississippi boards: for architects, see 30 Miss. Admin. Code Pt. 201, R. 3.2.4, landscape architects under Pt. 202, R. 1.11.3, and engineers and surveyors under Pt. 901, R. 6.2.3. None reaches an RPG; for the surveyor side, see our Mississippi land surveyor seal page.
Do the seal rules cover an expired or suspended registration?
No. Rules 1.15 and 10.1 to 10.5 say nothing about expiry, suspension or revocation, about a new number at reinstatement, or about handing the seal back.
Renewal and discipline fall under the Board and Miss. Code Ann. Title 73 ch. 63. Because Part 1101 was last amended on June 13, 2023, check the current text before relying on any provision.
What should you confirm before the first sealed sheet?
That the device matches the Board's adopted artwork and that your title block sets the name line as name, comma, one space, RPG. Stamp a test sheet and check that the impression lands near the name and stays legible.
Then confirm that each sheet template leaves room for your signature and the date, and that review work carries the Rule 10.2 wording.
Frequently asked questions
Does the seal replace the RPG name line?
No. Rules 10.3 and 10.4 call for both: your typeset name followed by RPG, and the seal placed close to it.
Is a firm seal part of the Mississippi RPG rules?
Part 1101 sets no firm seal and requires no firm information on the device; certification is the individual registrant's duty. The certificate of authority under Miss. Code Ann. § 73-13-43 applies to firms practicing engineering or surveying, not geology.
Can one certification page cover a bound report printed in small numbers?
Rule 10.5 grants the certification page to pamphlets and open file reports reproduced in large numbers. Outside that case, reports and bulletins fall under Rule 10.4 and the sheet by sheet duty in Rule 10.1.
Is the review sentence needed on work I prepared myself?
Rule 10.2 ties that sentence to geologic studies and projects certified by review. Work you prepared, or that was prepared under your direct supervisory control, is certified under Rule 10.1 by seal, signature and date.
Should my documents say registered or licensed?
The rules use registered. Your regulator is the State Board of Registered Professional Geologists, and the designation its rules put after your typeset name is RPG.
With the Board's adopted artwork in hand, order your seal from our Mississippi stamps and seals collection.
