NANPA records 3 assigned NXX blocks to rate center CAMP HILL in area code 256, 0.4% of the 786 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 2 holders hold those blocks, the largest being WINDSTREAM ALABAMA, INC. (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AL (1). The earliest assignment on record here is 2009-02-18 and the most recent 2018-04-10. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
