MT SHASTA prefixes in area code 530
NANPA records 8 assigned NXX blocks to rate center MT SHASTA in area code 530, 1.0% 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. 7 holders hold those blocks, the largest being PACIFIC BELL (2), LEVEL 3 COMMUNICATIONS, LLC - CA (1), UNITED STATES CELLULAR - CA (1). The earliest assignment on record here is 2001-05-18 and the most recent 2021-07-27. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
