MOORPARK prefixes in area code 805

NANPA records 23 assigned NXX blocks to rate center MOORPARK in area code 805, 2.9% 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. 11 holders hold those blocks, the largest being PACIFIC BELL (10), ONVOY, LLC - CA (2), BANDWIDTH.COM CLEC, LLC - CA (2). The earliest assignment on record here is 2002-02-21 and the most recent 2022-02-28. 19 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.

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.
