SIMPSONVL prefixes in area code 864

NANPA records 13 assigned NXX blocks to rate center SIMPSONVL in area code 864, 1.7% 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. 7 holders hold those blocks, the largest being FRONTIER COMMUNICATIONS OF THE CAROLINAS INC. - SC (5), ONVOY SPECTRUM, LLC (2), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2002-08-20 and the most recent 2024-09-04. 11 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 502, 821 – overlay codes cover the same geography, so a rate center is served by all of them.
