BIGGS prefixes in area code 530

NANPA records 6 assigned NXX blocks to rate center BIGGS in area code 530, 0.8% 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. 5 holders hold those blocks, the largest being ONVOY, LLC - CA (2), NEW CINGULAR WIRELESS PCS, LLC (1), U.S. TELEPACIFIC CORP. DBA TPX COMMUNICATIONS (1). The earliest assignment on record here is 2022-06-29 and the most recent 2022-11-23. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
