Virginia professional engineer seal requirements are set by the Board for Architects, Professional Engineers, Land Surveyors, Certified Interior Designers and Landscape Architects under 18VAC10-20-760. The seal must be a two-inch circle containing your full licensed name, the words “Commonwealth of Virginia,” the designation “Professional Engineer,” and your six-digit license number. It goes, along with your signature and the date, on every final engineering document you produce or directly supervise.1Virginia Code Commission. 18VAC10-20-760 – Use of Seal
The Four Required Elements and the Size
The regulation prescribes a uniform circular design exactly two inches in diameter. Four pieces of information must appear on it:
- Your full name as it appears on your license
- The words “Commonwealth of Virginia”
- The designation “Professional Engineer”
- Your six-digit license number
Leading zeros in the license number may be left off the seal itself, but the number has to be there so the license can be verified.1Virginia Code Commission. 18VAC10-20-760 – Use of Seal
The board does not supply seals. You order your stamp or embosser from a private vendor and are personally responsible for making sure the layout and dimensions match what the regulation requires. A nonconforming seal can get documents rejected by building officials and permitting authorities, and it can draw board scrutiny.
What Documents Need Your Seal
Every final document produced in your engineering practice needs your seal, your signature, and the date. That means the cover sheet of a plan set and each individual sheet of plans or drawings, plus technical reports, specifications, and plats. The requirement covers work you prepared yourself and work prepared by someone else under your direct control and personal supervision.1Virginia Code Commission. 18VAC10-20-760 – Use of Seal
Preliminary and advance-copy documents are different. They do not need to be sealed, signed, or dated, but they must be clearly labeled as incomplete. Skip the label and a draft can be mistaken for finished engineer-approved work and used in the field, which puts you on the hook for a product you never finalized.1Virginia Code Commission. 18VAC10-20-760 – Use of Seal
What You Are Certifying When You Seal
Applying the seal is a declaration that you exercised direct control and personal supervision over the work. That standard is strict. You cannot seal drawings produced by a third party you had no involvement with, and you cannot seal work done by an unlicensed person unless that person worked under your direct oversight through the project.1Virginia Code Commission. 18VAC10-20-760 – Use of Seal
Plan-stamping as a favor, or signing off on a project you only glanced at near the end, violates the rule. The board takes it seriously because the seal exists to guarantee that a qualified professional actually drove the technical decisions.
Applying the Seal: Physical and Electronic
Rubber Stamp or Embosser
With a physical seal, your original handwritten signature and the date of signing go on each sealed document. The ink should be permanent and the impression legible enough to survive scanning and long-term storage. Each sheet of a plan set gets its own seal, signature, and date. Not just the cover.1Virginia Code Commission. 18VAC10-20-760 – Use of Seal
Electronic Seal
Virginia allows an electronic seal, signature, and date in place of a physical one if the electronic version meets three criteria. It must be a unique identification of you as the professional, it must be verifiable, and it must remain under your direct control.1Virginia Code Commission. 18VAC10-20-760 – Use of Seal
The regulation sets a performance standard rather than naming a specific technology. Most engineers rely on PDF-based digital signature tools that meet the unique, verifiable, and controlled test. Whatever tool you choose, you carry the burden of showing it satisfies all three conditions if the board asks.
What Happens If You Get the Seal Wrong
Sealing violations fall under the board’s standards of practice, and the board can discipline any licensee who breaks them. Under 18VAC10-20-790, sanctions require a majority vote of the full board and can run from a formal reprimand through monetary penalties, probation, license suspension, or permanent revocation.2Virginia Regulatory Town Hall. 18VAC10-20 – Board for Architects, Professional Engineers, Land Surveyors, Certified Interior Designers and Landscape Architects Regulations
Your seal is only valid while your license is active. Continuing to stamp documents after a lapse is treated as unlicensed practice.
How Long to Keep Sealed Project Files
Virginia Code ยง 8.01-250 sets a five-year statute of repose for claims based on defective design, planning, surveying, or construction supervision of improvements to real property. The clock starts when you finish providing the services, not when someone discovers a defect. After five years, no new claim can be brought on that work no matter when the problem shows up.
At a minimum, hold your sealed project files for five years after completing the project. Many engineers keep them longer, because disputes over exactly when the repose period began can push the effective window out by months.
