CASTLEHAYN prefixes in area code 910

NANPA records 7 assigned NXX blocks to rate center CASTLEHAYN in area code 910, 0.9% of the 785 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. 6 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (2), CENTURYLINK COMMUNICATIONS LLC - NC (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NC (1). The earliest assignment on record here is 2003-06-19 and the most recent 2021-11-22. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 472 – overlay codes cover the same geography, so a rate center is served by all of them.
