Let me clarify, when you purchase a gun from a dealer, they must be registered at the point of purchase. The carry permit comes from the most local police or sheriff agency, mine would be from Georgetown, IN sheriffs office. I dont know what they are good for, but they are required for sale. Most auctions I go to also require them, and most have a dealer on site or lined up for the guns to go to. If you have a permit, you can take it with you, if the dealer is present.
