Communications are routed in a communications network based on a location of a requesting party. A communication from the requesting party is received. A location of the requesting party is determined using a geographic address which defines the smallest of two of a set of multiple geographic areas defined by multiple available geographic addresses for the location of the requesting party. A communications destination address for the communication is selected, from multiple possible communications destination addresses, based on the location of the requesting party. The communication is forwarded to the selected communications destination address.
