GRIDLEY prefixes in area code 530
NANPA records 5 assigned NXX blocks to rate center GRIDLEY 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 ONVOY, LLC - CA (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - CA (1), LEVEL 3 COMMUNICATIONS, LLC - CA (1). The earliest assignment on record here is 2005-07-12 and the most recent 2022-11-18. 5 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 codes 309, 620 – overlay codes cover the same geography, so a rate center is served by all of them.
