    What is a PE?

    Many types of jobs require licensure including doctors, lawyers, public accountants, and engineers.

    A Professional Engineer (P.E.) is an engineer that holds a license to practice engineering in one or more states. The license symbolizes that the engineer has met the state’s education, exam, and professional experience requirements. This demonstrates competency in a specific field of engineering.

    Professional Licensure and the P.E. Stamp

    By affixing their stamp, a Professional Engineer (PE) legally certifies that a drawing, report, or specification was prepared under their direct supervision and strictly complies with all applicable codes to protect public safety.

    • License Revocation: State licensing boards can permanently revoke an engineer's PE license for unethical behavior or gross negligence, ending their legal ability to practice.

    • Legal Accountability: The PE stamp creates a legal trail directly linking the individual engineer to the built structure.

    The Stamping/Sealing of Project Work

    Each state determines the specific rules for apply a stamp/seal to a project. The seal typically displays the engineer’s full name, license/registration number, state or provincial jurisdiction, and discipline (when required).

    To execute the stamp, the engineer applies the seal and then signs and dates the document directly over or adjacent to the seal. This process establishes legal accountability, confirms compliance with relevant codes and safety standards, and is required before plans can be submitted to regulatory authorities for construction or permit approvals.

    There are a number of approved methods for stamping/sealing project work. These include:

    Physical Seal: An image containing the seal artwork, engineer’s name, state, and license number is placed directly onto the document. The image is made using an ink rubber stamp or embossed impression.

    Graphic Seal Layer: An electronic image (PDF or CAD block) containing the seal artwork, engineer’s name, state, and license number is placed directly onto the drawing title block.

    Cryptographic Digital Signature: A Public Key Infrastructure (PKI) digital certificate, issued by a third-party Certificate Authority after verifying the engineer's identity, is applied to the electronic document.
