How do I verify a contractor license in Washington?

Search the business name on DingDongWork to see its Washington license numbers, status and expiration dates, then confirm the record with the issuing agency (Washington Department of Labor & Industries) at https://secure.lni.wa.gov/verify/.

What does an active license mean in Washington?

An active license means the state listed the license as current when its records were published. Licenses can expire, be suspended or be renewed afterwards, so always check the agency's live record before signing a contract.

Why is a business I know not listed?

DingDongWork lists businesses that hold an active license with a published address or phone number. Individuals' professional licenses and inactive records are not listed, and some trades are licensed locally rather than by the state.
