An improved caller ID system for providing geographic location information about an incoming call to a cell phone is provided. The area code of an incoming call based on the caller ID information is detected and an area code database is accessed within the cell phone or on the cellular network. The corresponding geographic location of the detected area code for the incoming call is retrieved from the database and displayed for the user on the cell phone, either automatically in response to the incoming call or upon actuation of the function by the user.
