WINCHESTER prefixes in area code 540

NANPA records 38 assigned NXX blocks to rate center WINCHESTER in area code 540, 4.8% 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. 11 holders hold those blocks, the largest being VERIZON VIRGINIA, INC. (11), NEW CINGULAR WIRELESS PCS, LLC - DC (9), OMNIPOINT COMMUNICATIONS CAP OPERATIONS, LLC (4). The earliest assignment on record here is 2001-02-12 and the most recent 2021-04-24. 30 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 217, 447, 603, 765 – overlay codes cover the same geography, so a rate center is served by all of them.
