A Guam professional engineer seal must show the designation Professional Engineer, your registered name and number, your specific engineering discipline, and the date your registration expires, printed or left blank to fill in. You sign it by hand, with a date and a certification sentence. This page covers seal wording, medium, signing, sealed submissions, computer-generated limits and expiration.

Guam is one row in our professional engineer seal requirements by state table, which sets each jurisdiction's rule side by side.
What must a Guam professional engineer seal show?
Five items: the designation Professional Engineer, your registered name, your registration number, your specific engineering discipline, and when your registration expires, either printed or left as a blank space to write in. The list is in 22 GCA § 32116(d).
Plan for the discipline and the expiration field from the start. Both take space on the face, and a layout built only for a name, a number and a designation will run short of room once they are added.
The statute asks for your specific discipline, so give it in full rather than as a general label. Spell your name the way your registration shows it.
Should the expiration date be printed on the seal or left blank?
The statute accepts either, but they age differently. A printed date makes the seal obsolete at renewal, so it has to be recut. A blank space lets you write the current expiration date in by hand.
The statute contemplates the expiration date appearing on the face of the device itself. That is why a printed version has a working life tied to one registration period, and why the blank-space version keeps working after you renew.
Choose the printed date if you prefer a finished look and accept a new seal every cycle. Choose the blank if you want one seal to serve through several renewals.
How large is a Guam engineer seal?
The rules cited here state no size and no shape. The Guam engineer seal is manufactured at 1-1/2 inches, which is a production size for this jurisdiction and not a figure taken from 22 GCA § 32116(d).
With five items to fit, including a discipline line and an expiration field, the layout matters more than the outside dimension. If you choose the blank-space version, check that the field leaves enough room to write a full date by hand.
What seal medium does Guam allow?
The seal may be an image, an imprint or another medium that has Board approval, under subsection (d)(1), and whatever you use must leave a permanent mark on the sealed document, under subsection (d)(2). 25 GAR § 1109 repeats the permanent-mark point.
The Board has a role here: the statute refers to a medium the Board has approved, so the choice of medium is not left entirely to the buyer. An impression that can fade or be wiped away does not leave a permanent mark, whatever the medium. The full citation is 22 GCA § 32116(d)(1), (d)(2) and (d)(4).
How do you sign and date a Guam seal?
Three things go with a Guam seal: your signature in your own hand, the date, and a certification sentence, under 22 GCA § 32116(d)(1) and (d)(4). This page does not reproduce the certification sentence, so take its exact wording from the statute itself.
The statute also bars two signing shortcuts that are widely sold alongside stamps. This page does not list them either; read those subsections before you buy any signature product for Guam work.
In practice, keep a pen with the stamp: you sign by hand, add the date, and include the certification sentence.
Can a Guam engineer sign or date by computer?
No. Subsection (d)(1) does not accept a computer-generated signature or a computer-generated date. That holds even when the seal itself is applied as an image: the seal may be an image, but the signature stays handwritten.
An electronic process that applies the signature and date automatically does not meet the statute. Plan your submission workflow so the signing and dating step happens by hand.
Which submissions must carry the Guam seal?
Every technical submission you present to a client, or to an agency that is public or governmental, takes the seal. Subsection (d)(3) sets that scope, and the full citation is 22 GCA § 32116(d)(3), (d)(4), (d)(8) and (d)(13).
Private clients count as much as agencies. If a technical submission leaves your hands for a client, it falls inside the rule, not only when it goes to a permitting office.
What happens to your seal when your Guam registration expires?
After your certificate expires it is unlawful to affix your seal and signature, or a facsimile of them, and it is equally unlawful to let anyone else affix them. That rule is in subsection (d)(7).
Expiration has a physical side in Guam too. A seal with a printed expiration date goes out of date at renewal and has to be recut, while a blank-space seal takes the new date by hand. The citation for both points is 22 GCA § 32116(d)(7) and (d).
What should you send when ordering a Guam engineer seal?
Send your registered name, your registration number, your specific discipline, and your choice for the expiration field: a printed date or a blank space. Professional Engineer is set on every Guam engineer seal.
If you choose a printed date, give the expiration date from your current registration and plan on a new seal after you renew.
How do you check a Guam impression before using it?
Seal a test sheet and confirm all five items are present, including the discipline and the expiration date or blank. Then check that the mark is permanent on the paper you actually use for submissions.
Sign by hand, add the date and the certification sentence as you would on a final submission, and make sure all of it reads clearly together. If the blank field is too tight for a handwritten date, catch that now.
Guam sets separate seal rules for other licensed professions too; see the Guam architect, landscape architect and land surveyor seal requirements.
Frequently asked questions
Can the Guam seal go on a PDF as an image?
The statute allows the seal to be an image, an imprint or another medium with Board approval, provided it leaves a permanent mark. The signature and date are another matter: subsection (d)(1) does not accept computer-generated versions of either.
Does the discipline replace the words Professional Engineer?
No. The statute lists the Professional Engineer designation and the discipline as two separate items under 22 GCA § 32116(d), so the seal carries both.
Do government in-house designs need the seal?
Yes. Subsection (d)(3) includes designs a government produces in house among the technical submissions that take the seal.
Can I seal work to help an unregistered person get it accepted?
No. Subsection (d)(7) makes it unlawful to affix a seal and signature, or allow them to be affixed, when the aim is to aid or abet someone trying to get around the chapter.
Which board oversees Guam engineer seals?
The Board of Registration for Professional Engineers, Architects, and Land Surveyors. The seal requirements themselves are written into statute at 22 GCA § 32116(d), and the statute gives the Board a say in approving the seal medium.
