Licenses are generally issued by the state. They may be limited to state residents and even then can be in demand. They often cover very specific time periods, locations, etc. When available, non-resident licenses can be very expensive, e.g., a trapping license in Georgia is $300 if you don't live there.

The privileges provided depend on which type of licenses you purchase, e.g., fishing, hunting, weapon type, trapping, etc., etc., and privileges vary from county to county. It's your responsibility to know the law where you are.

Bottom line is most people know the law where they live and the one or two places they frequent most and that's about it.
