BLACKSBURG prefixes in area code 540

NANPA records 21 assigned NXX blocks to rate center BLACKSBURG in area code 540, 2.7% of the 786 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 VERIZON VIRGINIA, INC. (7), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - VA (4), LEVEL 3 COMMUNICATIONS, LLC - VA (3). The earliest assignment on record here is 2009-06-12 and the most recent 2021-12-08. 17 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 826, 864 – overlay codes cover the same geography, so a rate center is served by all of them.
