Washington contractor license lookup
Every contractor performing work in Washington must be registered with the state Department of Labor & Industries. This tool searches that public registration record by business name or license number and shows you the registration status, the license type, when it took effect, when it expires, and the principal on file.
It matters before you hire. Registration is what stands behind a bond claim, and an expired or suspended registration is a signal to stop and ask questions — an unregistered subcontractor can leave you carrying the consequences of their work, their injuries, and their tax reporting. Checking takes seconds; unwinding the alternative does not.
Search by business name or by license number, for example a name fragment like RIDGE, or a license number in L&I's format.
Data comes from the Washington State Department of Labor & Industries public contractor registration dataset, published at data.wa.gov. It reflects registration status only. It is not proof of current insurance coverage, and registration records can lag real-world changes by several days. Confirm coverage with a current certificate of insurance.
Common questions
- What does an active Washington contractor registration mean?
- It means the business is currently registered with the Washington State Department of Labor & Industries as a contractor, and that registration has not expired, been suspended, or been revoked. Registration is the legal minimum to advertise or perform contracting work in Washington.
- Does registration mean the contractor has insurance?
- No. Registration requires a surety bond and proof of liability insurance at the time of registration, but this dataset shows registration status only, and it is not evidence of current coverage. A policy can lapse or be cancelled while a registration stays active. Verify coverage with a current certificate of insurance from the contractor's agent.
- What if I cannot find a contractor?
- The business may be registered under a different legal name than the name it trades under, so try the legal entity name, a shorter fragment of it, or the license number. If nothing matches, the contractor may not be registered in Washington, or may work under another company's registration.
- How current is this data?
- It comes from the Washington State Department of Labor & Industries public contractor registration dataset published on data.wa.gov. It is refreshed on L&I's own schedule and can lag recent registrations, renewals, and status changes by days. Treat it as a strong indicator, not a real-time record.
Checking one contractor is easy. Checking forty is not.
