NIPOMO prefixes in area code 805

NANPA records 6 assigned NXX blocks to rate center NIPOMO in area code 805, 0.8% 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. 3 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - CA (3), PACIFIC BELL (2), LEVEL 3 TELECOM OF CALIFORNIA, LP - CA (1). The earliest assignment on record here is 2022-01-13 and the most recent 2022-01-13. 6 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.
