BLACKSBURG prefixes in area code 864

NANPA records 11 assigned NXX blocks to rate center BLACKSBURG in area code 864, 1.4% 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. 9 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SC (3), SUNCOM DBA T-MOBILE USA (1), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2014-01-08 and the most recent 2024-05-13. 10 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 540, 826 – overlay codes cover the same geography, so a rate center is served by all of them.
