SOUTHTAHOE prefixes in area code 530

NANPA records 19 assigned NXX blocks to rate center SOUTHTAHOE in area code 530, 2.4% 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 (7), NEW CINGULAR WIRELESS PCS, LLC (3), T-MOBILE USA, INC. (2). The earliest assignment on record here is 2001-06-26 and the most recent 2007-05-16. 17 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
