BLACKSTONE prefixes in area code 434

NANPA records 8 assigned NXX blocks to rate center BLACKSTONE in area code 434, 1.6% 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. 6 holders hold those blocks, the largest being CORETEL VIRGINIA, LLC - VA (2), BRIGHTSPEED OF VIRGINIA, LLC (2), CENTURYLINK COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2001-03-08 and the most recent 2021-08-11. 7 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 508, 774 – overlay codes cover the same geography, so a rate center is served by all of them.
