NEVADACITY prefixes in area code 530

NANPA records 9 assigned NXX blocks to rate center NEVADACITY in area code 530, 1.2% 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. 6 holders hold those blocks, the largest being PACIFIC BELL (3), ONVOY, LLC - CA (2), TELEPORT COMMUNICATIONS AMERICA, LLC - CA (1). The earliest assignment on record here is 2017-01-16 and the most recent 2017-01-16. 8 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 837 – overlay codes cover the same geography, so a rate center is served by all of them.
