The Buchanan County Sheriff’s Office is warning of an active telephone scam.

Officials say people are getting calls which claim you’ve won a contest. They’ll offer you a confirmation number, and instruct you to call a phone number or visit a Web site to enter the confirmation number.

They will also ask you to send money for processing.

The sheriff’s office says if you get a call from this phone number, you should not participate.

The number is (866)996-5997.
