Jurisdictions marked as requiring a state-level license

The State Licensing Board records summarized here cover 50 states plus Washington, DC, across 20 tracked trade categories. This Trade Coverage Ranking is a count of state-level flags only; each linked record carries its own board context and dataset vintage.

Read the count carefully. A high coverage count means more state-level records are marked as requiring a license for that trade. It is not a quality, safety, enforcement, insurance, or local-permitting rating. Open the linked trade and state records, then verify the current rule with the relevant authority.
