What a Missouri professional engineer stamp identifies
A Missouri professional engineer stamp identifies the licensed engineer responsible for the covered final technical submissions. The seal accompanies the signature and date on work prepared by the licensee or under the licensee’s immediate personal supervision. It does not transfer responsibility for work outside that supervision.
Missouri’s individual-seal rule applies to licensed professionals, excluding interns and people in training. It covers final documents such as drawings, specifications, exhibits, reports and certifications of construction. The rule also explains how to identify preliminary work and how different professionals document their respective responsibilities.
The Missouri professional engineer stamp design
The individual seal is 1¾ inches in diameter. State of Missouri appears between two concentric circles at the top and Professional Engineer at the bottom, in Roman capital letters. Your name and license number appear within the inner circle, with PE preceding the number.
The chapter also describes the board’s own official seal. That separate 2¼-inch specification does not apply to the personal Missouri engineer seal sold here. Likewise, the size of the Trodat housing is not a measurement of the finished impression. The exact listing does not report a measured finished die diameter.
Engineers licensed before January 1, 2002 may use the older Registered Professional Engineer wording and E prefix. This exact product’s illustrated format uses Professional Engineer and PE. Its form has no selector for the older format, so this page does not offer a separate legacy-layout product.
The Trodat 46050 mount and optional supplies
This Missouri professional engineer seal uses one Trodat 46050 self-inking housing. A built-in pad inks the die between impressions, and the open base helps position the impression on paper. Nonslip pads support placement, and the internal pad can be re-inked or replaced.
The photographs show the housing with its open lower frame; the personalized seal face is underneath and is not pictured as a finished impression. Choose the ink and matching supplies shown in this product’s form. The optional refill bottle contains 1 oz of ink, and the combination option contains a pad and refill bottle.
The supplied ink is water based and will not dry on glossy paper or Mylar. Choose a suitable paper surface rather than assuming that an ink color changes the surface compatibility. This listing offers nine ink choices, including Dry, in the order shown above.
Ordering a PE stamp Missouri engineers can personalize
Set Qty, enter Registrant Name and License Number, then check the preview against your issued details. Enter the complete license number, including its PE prefix, so it is preserved in the order. This page does not add a second PE prefix to your entry.
Choose your ink and any accessories, add special instructions and review the running total. The digital file, refill ink, extra pad and combination remain independent choices. Selecting a separate pad or bottle as well as the combination adds additional supplies; it does not replace the combination.
The exact source form captures the name and number. Your signature and signing date are applied when you issue or revise a document, rather than permanently engraved through these order fields. Check both licensed values before continuing because the preview is a guide to the personalized details.
Electronic files, signatures and revisions
The digital-file add-on supplies JPG and PDF artwork of your Missouri PE seal. Missouri permits a computer-generated seal image with the required size, design and content. The image does not itself sign the document, and the rule distinguishes the signature requirements for different document formats.
A paper drawing or other hard copy requires a handwritten wet signature. Native electronic files, such as a CAD or word-processing file, require digital authentication that is unique to the signer, verifiable, under sole control and linked so alteration invalidates the signature. For a PDF or similar format modified to be less easily altered, an accurate scan of the actual signature is acceptable.
Revisions require the responsible licensee’s signature, seal, date and an explanation of the changes. For bound multipage documents other than drawings, a properly identified title, index or seals page may cover the included pages. Contributions prepared under another licensee’s responsibility must be identified and sealed by that licensee as required.
Covered preliminary, incomplete, not-for-construction or specified as-built submissions need an obvious and legible disclaimer when issued in that status. Using a Missouri PE stamp is not a substitute for accurately identifying the stage of the work or the limits of professional responsibility.
Missouri engineer stamp questions
- What diameter is a Missouri professional engineer stamp?
- The individual licensee’s seal is 1¾ inches in diameter under 20 CSR 2030-3.060. The 2¼-inch dimension elsewhere in the chapter describes the board’s own official seal, which is a different seal.
- Which prefix belongs on this Missouri professional engineer stamp?
- The standard Professional Engineer format uses PE before the number. Enter the complete issued number. This page preserves your entry and does not insert a second prefix. The illustrated product is the standard format, without a separate legacy-format selector.
- Is the older Registered Professional Engineer format still permitted?
- The rule permits that wording and the E prefix for engineers licensed before January 1, 2002. This exact product illustrates the standard Professional Engineer and PE format and does not offer an old-format selector.
- Does a JPG or PDF seal file count as a digital signature?
- No. The add-on supplies seal artwork. The signature requirements depend on the document format: native files require the specified digital authentication, while qualifying PDF or similar files may use an accurate scan of the actual signature.
- Can I seal revisions made by someone else?
- The rule assigns revisions to the licensee who made them or immediately supervised them, with signature, seal, date and an explanation. Revisions not made or approved by the licensee are prohibited; review the rule for shared and revised documents.
