I live in IN and was contacted by a "Unknown" (caller ID) who asked for me by name, gave a case number, and said that they needed to verify my mailing address, either work or home, in order to send mail. They left an 866-759-4225 number to call back but I haven't called them yet.
I read at your sticky entitled "So you've been contacted..." and it references if you were contacted by mail - in which case they already have your address. But it doesn't touch on if this person is calling you with no mail contact. Do I call them and give them my address and follow the same steps?
