CHESTERFLD prefixes in area code 843

NANPA records 5 assigned NXX blocks to rate center CHESTERFLD in area code 843, 0.6% 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. 4 holders hold those blocks, the largest being SANDHILL TEL. COOP., INC. (2), NEW CINGULAR WIRELESS PCS, LLC - GA (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SC (1). The earliest assignment on record here is 2002-04-09 and the most recent 2018-02-01. 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 codes 413, 419, 567, 636 – overlay codes cover the same geography, so a rate center is served by all of them.
