ABSTRACT:
A system and method for numbering plan area (NPA) split processing is disclosed. In one implementation, a query is received during a permissive dialing period. The query comprises a destination location that is associated with a first NPA. It is determined whether a first call processing record identifies a service that is NPA sensitive. The first call processing record is associated with a destination location that is undergoing a NPA split. The first call processing record is identified by the destination location and the destination location is associated with a first NPA. A second call processing record is then used for processing in place of the first call processing record when the first call processing record identifies a service that is NPA sensitive. The second call processing record is associated with the destination location that is undergoing an NPA split. The second call processing record is identified by the destination location and the destination location is associated with a second NPA.
