PLVL WEST prefixes in area code 530

NANPA records 25 assigned NXX blocks to rate center PLVL WEST in area code 530, 3.2% of the 782 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. 10 holders hold those blocks, the largest being PACIFIC BELL (8), NEW CINGULAR WIRELESS PCS, LLC (4), T-MOBILE USA, INC. (3). The earliest assignment on record here is 2002-02-22 and the most recent 2023-08-23. 16 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
