How Washington General Contractor license verification works
A General Contractor in Washington is licensed by the WA Contractor Licensing Board. PrimaryCheck looks the license up live at the board's public verification system (board lookup) by license number, or by name when no number is supplied. The record the board publishes is captured as evidence, hashed, and rendered into a proof PDF.
Fields returned for this board: license_number ubi name license_type specialties status issued expires suspended owners bonds insurances violations lapses debarments.
Board note: WA-LNI: L&I Verify (ASP.NET JSON page methods Controller.aspx/Search + GetBusinessDetails, session id from the start page; no captcha). Construction contractors, electricians, plumbers; HVAC is not a separate WA license. Firm licenses matched against listed owners.
