WHITTIER prefixes in area code 562
NANPA records 63 assigned NXX blocks to rate center WHITTIER in area code 562, 9.0% of the 702 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. 19 holders hold those blocks, the largest being FRONTIER CALIFORNIA INC. (14), ONVOY, LLC - CA (8), T-MOBILE USA, INC. (8). The earliest assignment on record here is 2001-01-16 and the most recent 2025-08-06. 51 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 907 – overlay codes cover the same geography, so a rate center is served by all of them.
