CHARLESTON prefixes in area code 843
NANPA records 186 assigned NXX blocks to rate center CHARLESTON in area code 843, 23.8% of the 783 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. 26 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (66), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SC (31), SUNCOM DBA T-MOBILE USA (24). The earliest assignment on record here is 2001-01-05 and the most recent 2023-05-23. 110 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.
