got a letter saying I won money and to call the number.

I received a check (for government service tax) and letter saying I won the American
family publishing sweepstakes. And to call this # 1-778-885-4077. Is this a scam

It sounds like I received the same letter from G&F Financial in Vancouver, BC with a check in the amount of $4980.00 from G&F Tronics in Florida.  While the check looks to be authentic in appearance at first glance, it seems to be missing some info, such as the address and phone number for the bank.  There are also too many other flags (no google match for names, businesses, addresses, etc.) in the letter that indicates this is a scam.  As the expression goes, if it seems too good to be true, it probably isn't.

That's the same letter I received. Check SunAmerican Bank, from G&F Tronics Inc.,
Jupiter. Fl. amount (4,980.00), Tax Agent Chelsen Fiester, claims agent:Steve Brown
and Nancy Dickons.We did not enter into no such sweepstakes. I have looked around
the web and you can fill out forms at the Federal Trades comm. or the Postal service.
My husband also received a call on his cell a week before the letter. said, he had
won large amount of money, but needed credit card information, My husband laughed and the guy hung up on him. I hope these people are caught. We will not be cashing
this check. Then they will have our bank information.

what if you cashed the check they sent you?
