CHARLESTON prefixes in area code 854
NANPA records 32 assigned NXX blocks to rate center CHARLESTON in area code 854, 17.6% of the 182 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. 24 holders hold those blocks, the largest being ONVOY, LLC - SC (5), BANDWIDTH.COM CLEC, LLC - SC (2), NUSO, LLC (2). The earliest assignment on record here is 2015-09-15 and the most recent 2026-09-21. 32 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 codes 217, 423, 447, 479 – overlay codes cover the same geography, so a rate center is served by all of them.
