A method and implementing computer system are provided in which users are enabled to create a database listing areas in which the user may be at any given moment and corresponding phone numbers to which calls directed to the user's phone number are re-routed if the user is in any of the designated areas when an incoming call is placed. In an exemplary embodiment, a global positioning system is implemented as a geographic locating device to determine the user's location at any time, and a routing server database is implemented and accessed to match the user's current location to one or more user-designated telephone numbers in an area proximate to the user's current location.
