S BERNDINO prefixes in area code 909
NANPA records 88 assigned NXX blocks to rate center S BERNDINO in area code 909, 11.2% 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. 20 holders hold those blocks, the largest being FRONTIER CALIFORNIA INC. (17), T-MOBILE USA, INC. (16), NEW CINGULAR WIRELESS PCS, LLC (14). The earliest assignment on record here is 2001-03-23 and the most recent 2024-04-22. 66 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 840 – overlay codes cover the same geography, so a rate center is served by all of them.
