SO CONWAY prefixes in area code 843

NANPA records 4 assigned NXX blocks to rate center SO CONWAY in area code 843, 0.5% 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. 3 holders hold those blocks, the largest being TWC IP ENABLED SERVICES, LLC (2), HORRY TEL. COOP., INC. (1), US LEC OF SOUTH CAROLINA, INC. (1). The earliest assignment on record here is 2007-01-15 and the most recent 2007-11-16. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
