EASTCONWAY prefixes in area code 843

NANPA records 11 assigned NXX blocks to rate center EASTCONWAY in area code 843, 1.4% 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. 5 holders hold those blocks, the largest being SUNCOM DBA T-MOBILE USA (5), HORRY TEL. COOP., INC. (3), US LEC OF SOUTH CAROLINA, INC. (1). The earliest assignment on record here is 2003-12-04 and the most recent 2022-04-20. 8 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 603, 854 – overlay codes cover the same geography, so a rate center is served by all of them.
