FOLSOM prefixes in area code 279
NANPA records 16 assigned NXX blocks to rate center FOLSOM in area code 279, 10.6% of the 151 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 (6), FRACTEL, LLC (4), BANDWIDTH.COM CLEC, LLC - CA (3). The earliest assignment on record here is 2020-03-25 and the most recent 2024-09-19. 16 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 916, 985 – overlay codes cover the same geography, so a rate center is served by all of them.
