INGLEWOOD prefixes in area code 424

NANPA records 39 assigned NXX blocks to rate center INGLEWOOD in area code 424, 8.5% of the 460 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. 16 holders hold those blocks, the largest being ONVOY, LLC - CA (8), LEVEL 3 COMMUNICATIONS, LLC - CA (4), BANDWIDTH.COM CLEC, LLC - CA (4). The earliest assignment on record here is 2006-03-28 and the most recent 2026-08-19. 38 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 310 – overlay codes cover the same geography, so a rate center is served by all of them.
