directory numbers (DN) at the same location as they change from one service

provider to another2. Location portability: Location portability is the ability of users to retain existing

DNs without impairment of quality, reliability, or convenience when moving from

one physical location to another. Location portability allows a given telephone

number to be associated with any network termination device, independent of

DNs without impairment of quality, reliability, or convenience when switchingfrom one service to another provided by the same telecommunications carrier.
