MCCORMICK prefixes in area code 864

NANPA records 4 assigned NXX blocks to rate center MCCORMICK in area code 864, 0.5% 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. 4 holders hold those blocks, the largest being FRONTIER COMMUNICATIONS OF THE CAROLINAS INC. - SC (1), NEW CINGULAR WIRELESS PCS, LLC - GA (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SC (1). The earliest assignment on record here is 2003-05-14 and the most recent 2004-02-13. 3 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 821 – overlay codes cover the same geography, so a rate center is served by all of them.
