What is the difference between Local Number Portability and Number Pooling?
A. Local Number Portability, also called Service Provider Portability, is the ability of users of telecommunications services to retain, at the same location, existing telecommunications numbers without impairment of quality, reliability, or convenience when switching from one telecommunications carrier to another. Number Pooling is a process by which the 10,000 numbers in a central office code (NXX) are separated into ten sequential blocks of 1,000 numbers each (thousands-blocks), and allocated separately to service providers within a rate center.
