A general contractor's procurement team vetting a subcontractor before signing a work agreement checks whether the firm holds a current, non-suspended Washington State contractor license, what trade specialties it is authorized to perform, and how long it has been continuously licensed to assess stability.

Detecting License Misrepresentation in Insurance Claims

A commercial insurance carrier investigating a property damage claim submitted by a contractor checks whether the claimant's business name and license number match an active record, whether the license was valid on the date of the alleged work, and whether the claimed trade specialty aligns with the work described in the claim.
