STANARDSVL prefixes in area code 434

NANPA records 6 assigned NXX blocks to rate center STANARDSVL in area code 434, 1.2% of the 509 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 BRIGHTSPEED OF VIRGINIA, LLC (3), OMNIPOINT COMMUNICATIONS CAP OPERATIONS, LLC (1), BANDWIDTH.COM CLEC, LLC - VA (1). The earliest assignment on record here is 2025-03-24 and the most recent 2025-03-24. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
