COARSEGOLD prefixes in area code 559

NANPA records 9 assigned NXX blocks to rate center COARSEGOLD in area code 559, 1.1% of the 785 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. 3 holders hold those blocks, the largest being SIERRA TEL. CO., INC. (5), NEW CINGULAR WIRELESS PCS, LLC (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (2). The earliest assignment on record here is 2011-08-18 and the most recent 2025-03-12. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
