I understand from correspondence I've received from the Attorney Generals Office of Pa. that a Spoof number is a number that a hiacker can put into the caller I.D. that replaces his actual calling number. It's a bogus number that can't be traced and therefore these people can get away with a lot of scams, and phoney phone calls to seniors who are older and possible senile and they prey on them and rob them of their savings and I.D.
