OJAI prefixes in area code 805

NANPA records 9 assigned NXX blocks to rate center OJAI in area code 805, 1.1% of the 786 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. 6 holders hold those blocks, the largest being ONVOY, LLC - CA (2), PACIFIC BELL (2), BANDWIDTH.COM CLEC, LLC - CA (2). The earliest assignment on record here is 2013-11-25 and the most recent 2022-01-26. 8 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 820 – overlay codes cover the same geography, so a rate center is served by all of them.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
