CONWAY prefixes in area code 843

NANPA records 12 assigned NXX blocks to rate center CONWAY in area code 843, 1.5% 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. 7 holders hold those blocks, the largest being FRONTIER COMMUNICATIONS OF THE CAROLINAS INC. - SC (4), PAETEC ITEL, LLC (3), TELNYX LLC (1). The earliest assignment on record here is 2002-06-13 and the most recent 2003-09-26. 7 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 252, 413, 417, 501 – overlay codes cover the same geography, so a rate center is served by all of them.
