NEWBURYPRK prefixes in area code 805

NANPA records 24 assigned NXX blocks to rate center NEWBURYPRK in area code 805, 3.1% 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. 9 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (8), FRONTIER CALIFORNIA INC. (6), UTILITY TELECOM GROUP, LLC - CA (2). The earliest assignment on record here is 2001-04-19 and the most recent 2024-02-20. 15 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.
