Oklahoma requires a state-level general contractor licence, but the corpus GroundCheck holds here (the Oklahoma CIB roofing-contractor register — roofing only; the CIB publishes no bulk file for the electrical, plumbing, mechanical or HVAC trades, and Oklahoma licenses no general contractors at the state level) cannot answer a general-contractor question — it is trade-only or municipal data. A miss is disclosed as an honest coverage gap, never presented as a clean bill. Alongside licence status, GroundCheck attempts a Secretary of State business-filing check and a federal court-judgment search for every business you search — coverage of those varies by state and is disclosed, as-of a specific date, on the report itself.
