As an engineer in New Hampshire, you are required to use a specific seal on all reports and other official documents. The following will give you a better understanding of the New Hampshire engineering seals and stamps to make sure you are in compliance with the regulations that pertain to your engineering discipline.
Seal Requirements
In the state of New Hampshire, engineering seals must have an outside diameter of 1 9/16” and an inside diameter of 15/16”. The larger outer circle contains a smaller inner circle that must be in the form of an unbroken line. Between these two circles, the words “State of New Hampshire” must be along the top of the seal along with “Professional Engineer” along the bottom. Within the smaller inner circle, New Hampshire engineering stamps and seals must include your name over three lines, your licensing number and the word “licensed” along the bottom.Using Your Seal
There are also requirements for using New Hampshire engineering seals and stamps. Any time you create plats, specifications, drawings, reports, and other documents that will be used in an official capacity, the seal must be used. Any time documents are submitted for the purposes of obtaining permits, construction and any other reports that will be used professionally, engineers must make sure that their official seal is used. Documents that are considered preliminary do not require the seal, as long as it is clearly marked as being such.
New Hampshire engineering seals and stamps can be obtained from any stamp or embosser manufacturer. However, it is important that each form, whether an inked stamp, an embosser, or a digital option, are identical to the seals required by the state.
New Hampshire seals and stamps can only be used on documents which the engineer created, or those that were created by others under his supervision. Additionally, affixing your seal to an official document denotes that you have verified all information and made sure that it meets all local and state requirements and codes.
It is also important to make sure that you are aware of the date on which your licensing expires. Using a seal after licensing has expired is considered a violation.
New Hampshire seals and stamps are available in a variety of rubber stamp options, including those that are self-inking or pre-inked. Engineers may also choose to use an embosser to affix the seal to the appropriate documents, or stamps that require manual inking for application.

When it comes to using New Hampshire seals and stamps, and making sure you are following all requirements, it is important that newly licensed engineers take the time to read through the New Hampshire Professional Engineers Administrative Rules. This will make sure you understand exactly what is required of you and the usage of your official seal to ensure you remain in compliance with the rules and regulations that are applicable to your engineering discipline.
