COLUSA prefixes in area code 530
NANPA records 3 assigned NXX blocks to rate center COLUSA in area code 530, 0.4% 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. 3 holders hold those blocks, the largest being CITIZENS TELECOMM DBA FRONTIER COMM GOLDEN STATE (1), COMCAST PHONE OF CALIFORNIA, LLC (1), BOOST SUBSCRIBERCO L.L.C. (1). The earliest assignment on record here is 2009-03-04 and the most recent 2023-05-01. 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 217 – overlay codes cover the same geography, so a rate center is served by all of them.
