Are digital Professional Engineer stamps legal in Illinois?

About Illinois Professional Engineer Seals
A Professional Engineer seal in Illinois is a legally recognized credential that proves a document was officially sealed by a licensed professional. Unlike traditional ink stamps, digital seals are cryptographically secured, tamper-evident, and instantly verifiable.
This guide covers everything Engineers in Illinois need to know about obtaining, using, and maintaining their professional seal. Whether you’re sealing construction drawings, engineering reports, or structural plans, this resource walks through the complete process.
Pro Tips
- Plan your 30 PDH per 2 years early. The board verifies completed CE at renewal, and the queue is longest in December–January.
- Keep your sealed project records for at least 7 years — the board can request them during an audit or complaint.

Stamp Specifications
The Illinois Department of Financial and Professional Regulation - Design Professionals publishes specific rules for what a Professional Engineer seal must contain. When you seal a document you take responsible charge of it — you certify that the work was prepared by you or under your direct supervision and that it conforms to the applicable codes and standards. EngineeringID generates seals that match the board’s format requirements, but it is your responsibility as the sealing professional to confirm compliance for your specific document type.
Required elements for a Illinois Professional Engineer seal:
- Full legal name
- License number
- Professional Engineer
- State of Illinois
- License expiration date
Illinois seal format: Design: Circular seal, 1-5/8 inches diameter · Size: 1-5/8 inches
Statutory authority: IAC §1380.295
Documents that commonly require a sealed Professional Engineer submission in Illinois:
- Construction drawings and specifications
- Structural, mechanical, electrical, and plumbing (MEP) designs
- Engineering reports and feasibility studies
- Permit applications submitted to Illinois building departments
- Any document where a licensed professional takes responsibility for technical content
Continuing Education
Illinois requires 30 PDH per 2 years of continuing education for Professional Engineers. Complete it before your renewal date — the board verifies CE at renewal and generally will not accept credits earned for a lapsed cycle.
- Keep certificates of completion; Illinois can audit your CE records after renewal.
- Courses must usually relate to your area of practice — confirm provider approval first.
- Carrying CE over from a previous cycle is typically not allowed.
Your digital seal remains valid as long as the license stays active, so completing CE on time keeps both your license and your sealing privileges uninterrupted.
Getting Licensed
To seal documents in Illinois, you must hold an active Professional Engineer license issued by the Illinois Department of Financial and Professional Regulation - Design Professionals.
License eligibility:
- Active, current Professional Engineer license with the Illinois Department of Financial and Professional Regulation - Design Professionals
- No restrictions, suspensions, or disciplinary actions on the license
- Continuing education: Illinois requires 30 PDH per 2 years to keep the license current
- Government-issued identification that matches the license record
Illinois licensure requirements: ABET-accredited engineering degree, 4 years experience, FE and PE exams.
Your Professional Engineer license already represents your qualification to seal documents. No additional examinations or certifications are required beyond your initial licensure and any mandatory CE required by Illinois.

Pitfalls to Avoid
1. Sealing without personal review. Never delegate sealing. By applying your seal you accept full professional and legal responsibility for the document’s contents.
2. Using an expired license. A seal is only valid while your underlying license is active. Renew your license well before its expiration date.
3. Sealing outside your competence. A Professional Engineer license authorizes work within your discipline - don’t seal documents in a field you’re not qualified to practice in.
4. Editing a document after sealing. A digital seal makes post-seal edits immediately detectable; an ink-stamped document may look fine but be legally invalid.
5. Sharing seal credentials. Your seal is tied to you personally. Sharing login credentials or letting another person apply your seal is fraud in every state.
6. Ignoring board-specific rules. State boards occasionally update required seal elements or document-type rules. Check the board’s website at least annually.
7. Losing the audit trail. Keep a log of what you sealed and for whom. EngineeringID maintains this automatically, but save copies of sealed PDFs for your own records.
License Renewal
Your seal remains valid for exactly as long as your underlying Illinois license is active and in good standing. When you renew your license with the state board, your seal is automatically renewed with no action required on your part.
License renewal basics:
- Renewal period: typically every 2 years for most Engineer licenses
- CE requirements: Illinois requires 30 PDH per 2 years — complete it before each renewal
- Fees: paid directly to the Illinois board
- Submission: through the board’s online portal or by mail
If your license expires: Your seal becomes invalid for new documents. Previously sealed documents keep their seal as a historical record, but verification will show the license is no longer active at the current date. Renew and your seal reactivates automatically.
If your license is suspended or revoked: Your seal is invalid immediately for new work. Historical seals remain verifiable but are clearly flagged. Reinstate the license through the board’s process to restore sealing privileges.
Best practice: Set a calendar reminder 60 days before your license expires. Keep your EngineeringID email address current so renewal notifications reach you.

Working Across State Lines
Many Professional Engineers hold licenses in more than one state. Your EngineeringID account supports every state you’re licensed in - add each license and issue seals that match the appropriate jurisdiction.
Key points for multi-state practice:
- One seal per state. Each sealed document must carry the seal for the state that jurisdiction the work was performed in. Never use a Illinois seal on a document intended for another state.
- Comity and reciprocity. Most states have comity agreements that allow a licensee in good standing in another state to obtain a license by endorsement. You still need the individual state license before sealing there.
- Per-state CE requirements. Each state sets its own CE rules. Track them separately - meeting Illinois’s CE obligation does not automatically satisfy another state’s.
If you expect to work across state lines, apply for additional licenses early. Board processing times vary from 2 weeks to several months.
