The Approved Seal is 1-3/4 inches in diameter, known as Size #1. In addition to indicating the State of Maine, the seal should bear the licensee’s name, license number, and the legend “licensed professional engineer.”
As shown in the image, it is preferred that the lettering be in all caps, so that the seal remains clear to read even after image transfer.
The license number must be present and may be designated by any term likely to indicate to an observer that it is the license number (e.g. License Number, No., #, etc.). Given that license numbers are becoming longer, and are the only number present on the seal, it is not required that any designation be present with the license number.
