Cellphone carriers retain customer data for up to 7 years

A leaked document from the Justice Department intended for law enforcement officials describes the length of time major cellphone companies retain sensitive customer data, including text message details and content.

Wired magazine reported that T-Mobile keeps a list of users’ text message recipients for up to five years and AT&T for up to seven years, according to the Department of Justice (DOJ) document dated August 2010.

Wired lists the retention periods of other carriers’ data, such as who keeps call detail records the longest (AT&T: up to seven years) and post-paid bill copies the longest (AT&T and Sprint: up to seven years).

Verizon Wireless is the only carrier that keeps text contents, although for three to five days.

The document, entitled “Retention Periods of Major Cellular Service Providers,” was obtained by the American Civil Liberties Union in North Carolina through a Freedom of Information Act request.

Jeffrey Nelson, a Verizon Wireless spokesman, said in an email to ABC News that the company would not comment on the details in the report.
