What a Montana professional engineer stamp is for

A Montana professional engineer stamp identifies the licensed engineer responsible for professional documents. Montana Code Annotated 37-67-314 requires licensees to sign, date and seal professional or technical documents created in their practice. The stamp supplies your personalized identity; it does not replace the signature, date or professional supervision required when you use it.

The board permits a seal on drawings, specifications and other documents prepared by you or under your supervision. A Montana PE stamp does not authorize work outside the authority of your license. The statute also prohibits signing or sealing documents, or taking responsible charge of a project, after your license expires. Buying or retaining the housing does not extend a license.

The Montana engineer seal information and size

Your seal carries your name, license number and Professional Engineer wording. The board’s license-seal FAQ specifies your first and last name and the word Montana. This product’s round layout uses Licensed Professional Engineer. Enter the numeric part of your license with its PE suffix, preserving meaningful leading zeros. The board distinguishes the seal number from the longer PEL-PE-LIC record identifier used on a license certificate.

ARM 24.183.511 authorizes commercially designated seal sizes: a 2-inch rubber stamp, a 2-inch desk seal and a 1⅝-inch pocket seal. This product uses the Trodat 46050, listed commercially as a 2-inch round model. The pocket-seal provision is a separate option, not a direction to shrink this rubber stamp. A housing photograph is not a measurement of the completed personalized impression.

The seal and signature must reproduce legibly on copies or prints of final original drawings. The reviewed provisions do not prescribe a particular impression color. Choose ink with the document surface and reproduction requirements in mind, then check the completed impression for readable names and numbers before using it on professional work.

The Trodat 46050 self-inking mount

This Montana professional engineer stamp is one exact product: the Trodat 46050 round self-inking housing with your Montana seal. Its internal pad supports repeated stamping. The open base helps position an impression, and nonslip feet help keep the housing steady. The pad can be refilled or replaced. The product-only gallery view shows the housing supplied for this listing.

The listed ink is water-based and does not dry on glossy paper or Mylar. A different color does not remove that limitation. Use a compatible surface. Replacement ink and pads are optional additions to the product, so review the selected extras rather than assuming that every gallery image or supply is included.

Ordering your Montana professional engineer stamp

Set Qty, then fill in Registrant Name and License Number in that order. Use your board-recorded name and the seal number with the PE suffix. The form preserves letters, punctuation and leading zeros. Choose Ink Color from Black, Pink, Red, Purple, Blue, Orange, Green, Dry and Brown. Check your licensed identity and selected ink before continuing.

Include a Digital File adds both JPG and PDF seal artwork. The remaining optional choices are Extra 1 oz Refill Ink, Extra Pad and Pad & Ink Combo. These are independent selections. The combo contains a matching pad and one-ounce bottle; choosing it together with a separate pad or bottle orders both selections. Quantity and the running total reflect the extras you select.

Special Instructions captures relevant order notes. This listing has no separate discipline, signature, signing-date or expiration-date engraving field. Your Montana professional engineer seal carries the licensed identity, while the signature and date are applied to the documents as required. Review the typed details, order quantity and supplies together before ordering.

Digital seal files and signing documents

The board permits a digital seal on plans, specifications, survey documents and reports. It may be reduced to half the size of the original seal, provided the required information remains legible. The optional Montana PE seal file provides personalized artwork in the two listed formats; it is not a signature certificate and does not add a signature or signing date.

The title page of plans and documents filed with public authorities must bear the seal and original signature of the licensee in responsible charge. Digital-seal permission does not erase that requirement or the statute’s instruction to sign and date. Confirm the receiving authority’s submission process for the documents involved. Keep the distinction between seal artwork and document authentication clear when preparing an electronic submission.

Montana professional engineer stamp questions

What number belongs on the PE stamp Montana engineers use?
Use the numeric part of your license with its PE suffix. Preserve meaningful leading zeros. The board’s FAQ distinguishes that seal format from the longer PEL-PE-LIC record identifier; do not copy that registry prefix into the seal number.
Why does this Montana engineer seal use the Trodat 46050?
The current rule lists the commercial 2-inch rubber stamp designation, and the 46050 is listed as a 2-inch round model. The rule’s separate pocket-seal size does not describe this product. The exact listing does not independently measure the finished personalized die.
Does a Montana professional engineer stamp need a date field?
This supplier form has no signing-date engraving field. Montana law requires signing, dating and sealing the professional documents when you use the seal. Entering your licensed name and number does not complete those document requirements.
Can I use the optional digital file instead of signing?
No. The optional files provide seal artwork. ARM 24.183.511 separately requires the responsible licensee’s original signature on the title page of plans and documents filed with public authorities; the statute also requires signing and dating.
Does Montana require black ink for the seal?
The reviewed seal provisions do not prescribe an ink color. They require the seal and signature to reproduce legibly. This mount uses the listed water-based ink, which does not dry on glossy paper or Mylar.
May I keep using my Montana professional engineer stamp after my license expires?
No. MCA 37-67-314 prohibits signing or sealing professional or technical documents and taking responsible charge after license expiration. Having a physical stamp or a digital copy does not preserve that authority.
