INYOKERN prefixes in area code 442

NANPA records 3 assigned NXX blocks to rate center INYOKERN in area code 442, 0.8% of the 356 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. 2 holders hold those blocks, the largest being FRACTEL, LLC (2), BANDWIDTH.COM CLEC, LLC - CA (1). The earliest assignment on record here is 2015-06-16 and the most recent 2020-12-30. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 760 – overlay codes cover the same geography, so a rate center is served by all of them.
