PE Stamp & Seal Requirements by State: Complete Guide
Twenty of the fifty-three engineering jurisdictions publish no seal size, New Jersey prohibits rubber stamp seals outright, and Minnesota does not require a seal at all. The size rule for every jurisdiction, where the signature goes, and how firm numbers and second seals work.

Michigan PE Seal Requirements: Design and Number
A Michigan PE seal has to carry the full ten digit license number exactly as the state issued it, and engineers routinely quote a shortened form. There is no diameter to hit, because the rule specifies the design by picture rather than by dimension.

Maryland PE Seal Requirements: Great Seal at Center
COMAR puts the pictorial Great Seal of Maryland at the center of a PE seal, so a generic multi state template cannot simply be relabeled. What surrounds it, where the expiration date belongs, and which documents a Maryland engineer has to seal.

North Carolina PE Seal: Wording, Firm Number, Files
North Carolina sets no PE seal diameter anywhere, and the state name is not one of the three elements the statute lists. The board design that controls layout, the firm number required on every sheet, and the rule about editable files.

California PE Stamp Rules: Size, Wording and Signing
California lets you buy a rubber stamp of your seal and forbids a rubber stamp of your signature, along with preprinted blank forms and decals of either. The 1.5 inch floor with no stated ceiling, and where the signature and date belong.

Florida PE Seal Requirements: Size, Signing and Sealing
A Florida PE seal is a minimum of 1-7/8 inches and goes on top of your signature, partially overlapping it, not beside it. The signature underneath must be made by hand, so a scanned or digitally created image of it does not count.

Pennsylvania PE Seal: 1-3/4 Inch and the 2022 Rewrite
Pennsylvania states one diameter rather than a range: the seal is 1 3/4 inch, with a pocket seal allowed down to 1 1/2 inch in the same proportions. What the December 2022 rewrite changed, and why older guidance describes repealed text.

Texas PE Seal Rules: Two Inch Maximum and the F Number
Texas publishes a maximum PE seal size rather than a minimum: no larger than two inches, with computer generated seals allowed to shrink. Why enlarging is the mistake, where your firm's F number has to appear, and why the signature stays off the seal.

Washington PE Stamp Rules: No Size, Sign Over the Seal
Washington gives no PE seal diameter, so any specific dimension quoted to you is not from the current rule. Two rules invert the usual advice: preliminary documents are stamped though not signed or dated, and the signature goes on top of the seal.

Iowa PE Seal Rules: Wording, Ink Color and the Block
A perfect Iowa seal on a document with no certification block is still a noncompliant submission. What the engineering block must carry, why the signature and handwritten date go in a contrasting ink color, and the fact Iowa states no diameter at all.

Arizona PE Seal Requirements: Branch, Size and Filing
An Arizona engineer registered in two branches buys two seals, because the rule requires one for each branch and a single die naming both does not satisfy it. The exact 1-1/2 inch specification, the date signed legend, and the imprint filed with the Board.

Massachusetts PE Seal Rules: Size and Per-Sheet Sealing
Massachusetts requires every filed sheet to be individually signed, sealed and dated, so a sealed cover sheet over an unsealed set does not comply. The depicted image runs approximately one and one half inches, and a forty sheet filing takes forty impressions.
