Abstract
A method for delivering enhanced caller identification (ID) service including geographic location information comprises initializing an originating switch with geographic identification data (GID). The GID is stored in each switch module memory, and is accessed by the originating switch each time a calling party initiates a call to a called party. If the called party subscribes to caller ID service, the calling's party directory number, and the GID associated with the switch is delivered to the called party as part of caller ID service so that the true geographic location of the caller can be ascertained.
