Colorado PE Seal Embosser for Engineers: Rules and Requirements

  • 3 min read
Colorado PE Seal

Engineers have a new way to show their professional license in Colorado. The PE seal embosser is an easy way to make your license visible and add a bit of personality to your documents. This article will discuss the benefits of having a PE seal embosser and how to use it correctly.

Rules From The Colorado State Board

The Colorado professional engineer stamp is approved by the State Board of Licensure for Architects, Professional Engineers, and Professional Land Surveyors. Under Section 12-25-117(1), the seal may be the rubber stamp type, computer generated, or the raised impression type.

The diameter for the Colorado engineer stamp should have an outer circle of 1-5/8" in diameter, while the inner circle should be 15/16" in diameter. Located in the center of the inner circle needs to be the license number of the engineer of whom the seal belongs to. It should also have the name that is on the registration of the professional engineer. Furthermore, the word “number” should not be located anywhere on the seal. If an engineer stamp has been obtained before June 1, 2005, it is still allowed to be used and is acceptable under Colorado law.

Using The Colorado Professional Engineer Stamp

According to the rules of the Colorado state board, a Colorado engineering seal has to be applied to the final reports, or the final electronic record of the following documents:

  • Every sheet of engineering drawings
  • The cover, title page, and table of contents
  • The title or signature page
  • The title page of details

On every document, whether it is hard copy or electronic, the licensee’s signature as well as the date of signature must be present. This can be done via electronic upload if applicable, but they must be visible through the Colorado professional engineer stamp. In the case of unfinished documents, the signing engineer must write a note describing the report as a preliminary one. Some examples of this type of note would be “for review,” “for bid only,” or “not for construction.”

Once a document has the Colorado professional engineer stamp affixed to it by the engineer, the engineer becomes responsible for the report. The professional engineer is allowed to set limits on the seal with certain disciplines. Two examples of these would be a structural engineer or a civil engineers. The licensed engineer must have a written statement next to the engineer's embossing seal that shows the scope of responsibility of the document.

The Colorado engineer embossing seal is available for purchase through various vendors online. A wide range of products are available to fit the engineer’s personal tastes, as well as the working environment for ease of use. Our self-inking stamp, pre-inked stamp, and embosser all typically ship within one day. Professional engineers who shop with us often get their electronic seal or proof in the same business day! No matter which type of Colorado engineer stamp is chosen, it must meet the requirements for the stated above.

Types of PE Stamps Available

There are many types of engineer stamps available, each with its own benefits. The three most common types of engineer seals are pre-inked, self-inking, and embossers.

Pre-inked Stamps

Pre-inked stamps offer a consistent impression quality on any document type. They are also very durable, with the ability to make up to 50,000 impressions before needing to be re-inked. The ink is applied to the stamp die with each impression, which means that there is no risk of smudging. Pre-inked engineer seals are available in a wide range of sizes and colors.

Self-Inking Stamps

A Self-inking stamp is very popular because they are easy to use and requires minimal effort. Simply press the stamp onto your document and the ink will be automatically applied. These stamps can make up to 5,000 impressions before needing to be re-inked, and the ink pads are available in a wide range of colors.


Embossers create a raised impression on your document, which gives it a professional look and feel. This type of engineer seal is perfect for important documents such as contracts, construction plans, and presentations. Embossers are available in a variety of frames depending upon your use.
