OXNARD prefixes in area code 805

NANPA records 75 assigned NXX blocks to rate center OXNARD in area code 805, 9.5% 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. 12 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (23), T-MOBILE USA, INC. (14), FRONTIER CALIFORNIA INC. (12). The earliest assignment on record here is 2001-03-22 and the most recent 2018-10-15. 59 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.
