Washington Contractor License Lookup
Check any Washington contractor registration by business name or license number. Includes active, expired, suspended and other statuses.
Tip: search a distinctive word in the name, e.g. "bridges electric".
How This Lookup Works
The tool searches a compact copy of the Washington L&I contractor registration file. It runs in your browser: your search terms are not sent to our servers. Results show the status exactly as L&I records it. Businesses that appear in our city lists also link to a profile with bond and insurance details.
Frequently Asked Questions
How Do I Check If a Contractor Is Licensed in Washington?
Search the business name or registration number above. Results show the status, expiry date, specialty and city from Washington L&I data. Confirm the result with the official L&I Verify tool before you sign.
What Does an Expired Status Mean?
The registration was not renewed by its expiry date. Washington registrations last two years (RCW 18.27.060). An expired contractor may not legally contract for work that requires registration until it renews.
Is This the Official State Lookup?
No. Verified Licensed is an independent directory using public-domain data published by Washington L&I on data.wa.gov. It is not affiliated with any government agency.
