As an aside to the NH DL comments: The address that appears by law on the front of your NH DL is your mailing address, not your residence address. You must use your residence address on your 4473. If your mailing and residence address are different, this can cause all sorts of "fun" when buying a firearm.
If you're like me, and your residence and mailing addresses are different, you probably would like to know that there's an option to have your residence address appear on the reverse of your NH DL. Makes firearm purchases much easier.
