FOID = Firearm Owners Identification Card. Without delving into the political side of things (which would get this thread deleted or many posts deleted) it's something that the wonderful Republik of Illinois has foisted on their populace. It's needed before you can purchase a firearm or any ammunition. Out of staters don't need it to buy ammo.
Actually you must have a FOID card to even own or have a gun in your possession, not just to buy.
