I would'nt think so. When I purchased with GID they did take my SSN when I placed my order with them, so I was concerned but when I placed an order with Ali at Dinar Trade, all he wanted was a address and phone number. There is no telling what you are going to do with your Dinar after you get them, so how would they (IRS) try and keep track of them? I've given away a few of mine to friends and family, but didnt share there names with anyone. But when you go to a coin dealer and pick up a proof set or go in and purchase some other currency, they dont take names then either.
Its all just money, IMO.
