BARNWELL prefixes in area code 803

NANPA records 15 assigned NXX blocks to rate center BARNWELL in area code 803, 1.9% 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. 6 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - GA (8), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SC (1). The earliest assignment on record here is 2001-03-27 and the most recent 2023-07-21. 11 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 839 – overlay codes cover the same geography, so a rate center is served by all of them.
