KENWOOD prefixes in area code 707

NANPA records 4 assigned NXX blocks to rate center KENWOOD in area code 707, 0.5% of the 785 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 ONVOY, LLC - CA (2), COMCAST PHONE OF CALIFORNIA, LLC (1), FRONTIER CALIFORNIA INC. (1). The earliest assignment on record here is 2008-02-15 and the most recent 2018-12-04. 4 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 369 – overlay codes cover the same geography, so a rate center is served by all of them.
