9-1-1

Phase II is a requirement of the Federal Communications Commission for wireless phone companies to provide an approximation of the 9-1-1 caller's location in the form of latitude and longitude.

Phase I is a requirement of the Federal Communications Commission for wireless phone companies to provide the address of the cell tower that processes a 9-1-1 call and the call back number of the cell phone to the Public Safety Answering Point.

Enhanced 9-1-1, or E9-1-1, is a system which routes an emergency call to the 9-1-1 center closest to the caller, AND automatically displays the caller's phone number and address. The Public Safety Telecommunicator will typically ask the caller to verify the information, which appears on his or her computer screen.

Nine-one-one is the number most people in the U.S. call to get help in a police, fire or medical emergency. A 9-1-1 call goes over dedicated phone lines to a Public Safety Answering Point (PSAP) and trained personnel then send the emergency help needed. 9-1-1 service is available in all Counties and Cities in Alabama.
