WMYRTLEBCH prefixes in area code 843

NANPA records 17 assigned NXX blocks to rate center WMYRTLEBCH in area code 843, 2.2% 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 NEW CINGULAR WIRELESS PCS, LLC - GA (8), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SC (4), HORRY TEL. COOP., INC. (3). The earliest assignment on record here is 2005-01-26 and the most recent 2008-09-16. 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 code 854 – overlay codes cover the same geography, so a rate center is served by all of them.
