WARRENTON prefixes in area code 540

NANPA records 18 assigned NXX blocks to rate center WARRENTON in area code 540, 2.3% 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. 6 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - VA (6), VERIZON VIRGINIA, INC. (5), NEW CINGULAR WIRELESS PCS, LLC - DC (3). The earliest assignment on record here is 2002-05-09 and the most recent 2020-11-23. 16 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 252, 503, 636, 706 – overlay codes cover the same geography, so a rate center is served by all of them.
