KELSEYVL prefixes in area code 707
NANPA records 6 assigned NXX blocks to rate center KELSEYVL in area code 707, 0.8% 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 PACIFIC BELL (3), ONVOY, LLC - CA (2), LEVEL 3 COMMUNICATIONS, LLC - CA (1). 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
