Is buying stolen CC numbers a crime? Using the numbers would be but would possession of the numbers be illegal?
You're seriously asking this? Yes, of course it is. 18 U.S.C. § 1029 and a host of related statutes. I'm not sure which is most commonly prosecuted, but seriously, you're asking if buying stolen credit numbers is a crime or not? WTF? Does it take a genius to realize it is?
I don't see anything about buying them. And I only see possession with intent to defraud mentioned.
