NASHVILLE (AP) — The Tennessee Department of Safety and Homeland Security is warning residents about a phone scam involving driver licenses.

Several citizens in west Tennessee have reported receiving phone calls regarding an issue with their 2012-2013 driver license renewals, and then the caller requests the person's Social Security number.

Commissioner Bill Gibbons says the department would never request confidential information in that manner.

He says official communication is sent by U.S. mail regarding driver's licenses, driver's license renewals or reinstatements.

The department's identity crimes unit is investigating the scam and is urging people to contact their local police departments to report identity crimes.
