Credentials differ by state and city, because the requirement itself does. Each listing says which one it holds.

This is a credential, not a trade. Every state’s general-contractor or builder licence, home-improvement registration and city building-permit history lands here, so a firm listed as a general contractor may frame houses or fit bathrooms. The listing shows exactly which credential it holds; the profile shows what it does.
