PULASKI prefixes in area code 540

NANPA records 7 assigned NXX blocks to rate center PULASKI in area code 540, 0.9% 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. 5 holders hold those blocks, the largest being OMNIPOINT COMMUNICATIONS CAP OPERATIONS, LLC (2), VERIZON VIRGINIA, INC. (2), ONVOY, LLC - VA (1). The earliest assignment on record here is 2001-11-19 and the most recent 2023-08-10. 6 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 315, 641, 680, 920 – overlay codes cover the same geography, so a rate center is served by all of them.
