Public Knowledge on Monday filed a Petition for Declaratory Ruling to ask the Federal Communications Commission to declare that phone carriers are running afoul of the Communications Act when they share customers? call logs with third parties. The Communications Act restricts how carriers may use or sell sensitive information known as customer proprietary network information (CPNI).

The Petition follows on the heels of reports that AT&T has been selling records of customers? phone calls to the C.I.A. Upon further investigation, Public Knowledge found that all four major mobile carriers (AT&T, Sprint, T-Mobile, and Verizon) have privacy policies that indicate they believe it is okay to sell or share similar records.

Public Knowledge was joined by the Benton Foundation, Center for Digital Democracy, Chris Jay Hoofnagle, Common Cause, Consumer Action, Electronic Frontier Foundation, Electronic Privacy Information Center, Free Press, the Center for Media Justice, the New America Foundation's Open Technology Institute, and U.S. PIRG.
