CARPINTRIA prefixes in area code 805

NANPA records 9 assigned NXX blocks to rate center CARPINTRIA 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. 5 holders hold those blocks, the largest being FRONTIER CALIFORNIA INC. (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (2), TELEPORT COMMUNICATIONS AMERICA, LLC - CA (1). The earliest assignment on record here is 2009-05-08 and the most recent 2024-05-08. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
