NOSAN JUAN prefixes in area code 530

NANPA records 5 assigned NXX blocks to rate center NOSAN JUAN in area code 530, 0.6% 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. 4 holders hold those blocks, the largest being PEERLESS NETWORK OF CALIFORNIA, LLC - CA (2), PACIFIC BELL (1), NORTH COUNTY COMMUNICATION CORPORATION - CA (1). The earliest assignment on record here is 2013-03-08 and the most recent 2023-04-18. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
