ABSTRACT:
A method and system for providing local number portability using a concept known as Geographic Unit Building Blocks (GUBB). Service providers (carriers) accept and use a map that divides a geographic area, such as a State, into sub-area GUBBs. The carriers operating within the State jurisdiction would then assign GUBBs to the telephone numbers they serve which accurately reflect each telephone number's geographic location on the State map. All ported numbers will have an explicit GUBB assignment as part of the location routing number (LRN) which would then be stored in the Local Number Portability (LNP) database used to provide translations for routing the call.
