telephone toll records

Telephone toll records contain telephonic routing information such as incoming and outgoing phone numbers, the time of calls, and their duration; they are historical records collected after calls take place and do not include the content of the communications.

Obtaining telephone toll records pursuant to a subpoena is a routine and lawful investigative step used by U.S. law enforcement and is generally regarded as not violating an individual's expectation of privacy.

Federal prosecutors can use a grand jury subpoena to obtain telephone toll records as part of criminal investigations.

Subpoenas for telephone toll records typically specify a defined date range (for example, a multi-day period) for which call-detail records are sought.
