LOMITA prefixes in area code 310
NANPA records 14 assigned NXX blocks to rate center LOMITA in area code 310, 1.8% 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. 6 holders hold those blocks, the largest being PACIFIC BELL (9), ONVOY, LLC - CA (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1). The earliest assignment on record here is 2005-01-03 and the most recent 2023-06-26. 5 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 424 – overlay codes cover the same geography, so a rate center is served by all of them.
