BIGSTONEGP prefixes in area code 276

NANPA records 7 assigned NXX blocks to rate center BIGSTONEGP in area code 276, 1.9% of the 374 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 ONVOY, LLC - VA (3), VERIZON VIRGINIA, INC. (2), TELEPORT COMMUNICATIONS AMERICA, LLC - VA (1). The earliest assignment on record here is 2016-08-09 and the most recent 2025-03-20. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
