MARS HILL prefixes in area code 828

NANPA records 5 assigned NXX blocks to rate center MARS HILL in area code 828, 0.7% of the 724 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. 4 holders hold those blocks, the largest being FRONTIER COMMUNICATIONS OF THE CAROLINAS INC. - NC (2), SUNCOM DBA T-MOBILE USA (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NC (1). The earliest assignment on record here is 2001-03-27 and the most recent 2022-02-17. 5 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 207 – overlay codes cover the same geography, so a rate center is served by all of them.
