CHESTER prefixes in area code 803
NANPA records 14 assigned NXX blocks to rate center CHESTER in area code 803, 1.8% of the 784 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. 5 holders hold those blocks, the largest being CHESTER TEL. CO. (6), NEW CINGULAR WIRELESS PCS, LLC - GA (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SC (2). The earliest assignment on record here is 2001-02-12 and the most recent 2026-04-20. 9 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 220, 304, 402, 406 – overlay codes cover the same geography, so a rate center is served by all of them.
