CALIMESA prefixes in area code 909
NANPA records 13 assigned NXX blocks to rate center CALIMESA in area code 909, 1.7% 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. 8 holders hold those blocks, the largest being FRONTIER CALIFORNIA INC. (4), T-MOBILE USA, INC. (3), BANDWIDTH.COM CLEC, LLC - CA (1). The earliest assignment on record here is 2013-04-08 and the most recent 2021-05-21. 10 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.
