OROVILLE prefixes in area code 530

NANPA records 22 assigned NXX blocks to rate center OROVILLE in area code 530, 2.8% 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. 11 holders hold those blocks, the largest being PACIFIC BELL (5), T-MOBILE USA, INC. (4), METROPCS, INC. (3). The earliest assignment on record here is 2007-03-08 and the most recent 2024-11-21. 19 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 code 509 – overlay codes cover the same geography, so a rate center is served by all of them.
