AUBN MAIN prefixes in area code 530
NANPA records 38 assigned NXX blocks to rate center AUBN MAIN in area code 530, 4.9% 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. 14 holders hold those blocks, the largest being T-MOBILE USA, INC. (9), PACIFIC BELL (8), NEW CINGULAR WIRELESS PCS, LLC (4). The earliest assignment on record here is 2001-05-18 and the most recent 2025-10-30. 31 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 837 – overlay codes cover the same geography, so a rate center is served by all of them.
