Abstract: A method for location-based communications routing includes determining a location of a requesting party in accordance with an address of the requesting party. Whether the location of the requesting party is in a first subscriber service area is determined and, when the location of the requesting party is not in the first subscriber service area, whether the location of the requesting party is in a second expanded subscriber service area larger than and including the first subscriber service area is determined. When the location of the requesting party is determined to be in the first subscriber service area, data corresponding to the first subscriber area is forwarded. When the location of the requesting party is determined to be in the second expanded subscriber service area, data corresponding to the second expanded subscriber service area is forwarded.

Abstract: A method for location-based communications routing includes determining a location of a requesting party in accordance with an originating communications address of the requesting party. The method also includes determining whether the location of the requesting party is in a first subscriber service area and, when the location of the requesting party is not in the first subscriber service area, determining whether the location of the requesting party is in a second expanded subscriber service area larger than and including the first subscriber service area. When the location of the requesting party is determined to be in the first subscriber service area, a communication from the requesting party is forwarded to a routing communications address associated with the first subscriber service area.

Abstract: A method, system and computer readable medium are provided for defining a service area served by a service location of a telecommunications network customer. The method includes ascertaining a geographic designator of a geographic area. The geographic area includes a plurality of geographic sub-areas that each correspond to a geographic sub-designator. The method also includes determining whether any two of the plurality of geographic sub-areas are not served by the same service location. When any two of the plurality of geographic sub-areas are not served by the same service location, the service area is defined by only the sub-designators corresponding to the geographic sub-areas served by the service location. When each of the plurality of geographic sub-areas are served by the same service location, the service area is defined by the geographic designator.
