PE License Lookup by State

How it works

Verify a professional license in three steps

  1. 1. Choose the jurisdiction

    Licenses are state-issued, so start with the state where the professional performed or sealed the work.

  2. 2. Match the identity

    Search the full name or license number and make sure the profession and jurisdiction match the document.

  3. 3. Confirm with the board

    Check active status, expiration, and board actions in the official licensing system before relying on the credential.

Why Verify Professional Licenses?

Protect Yourself

Ensure the professionals you hire are properly licensed and in good standing. Unlicensed practice puts your project at risk.

Verify Credentials

Confirm that stamped documents come from properly licensed professionals. Verify license numbers match the professional's name.

Legal Compliance

Many regions require verification of professional licenses before issuing permits or approving projects.

Check Disciplinary Actions

State boards maintain records of disciplinary actions and license restrictions. Know if there are any issues before hiring.

PE License Lookup FAQ

How do I look up a PE license?

Choose a state, then search by the professional engineer's name or license number. Confirm the current license status and any disciplinary history with the official state licensing board linked on the result page.

How do I look up an architect license?

Choose the state where the architect is licensed, search by name or license number, and confirm the record with that state's architecture board. Architect licenses are issued and verified by individual state jurisdictions.

Where can I find a landscaping license lookup?

Not here — the two are different credentials. A landscape architect license is a professional credential issued by a state board, and this directory verifies those. A landscaping contractor or business license is separate and may be issued by a state, county, or city, so check that authority directly.

Is a professional engineer license lookup free?

Yes. EngineeringID's state PE directories and links to official state board verification systems are free to use.

Who is the authoritative source for a PE license?

The licensing board in the state that issued the credential is the authoritative source. EngineeringID makes records easier to find and links directly to the appropriate board for final verification.
