BIGBEAR CY prefixes in area code 909

NANPA records 7 assigned NXX blocks to rate center BIGBEAR CY in area code 909, 0.9% 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. 4 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - CA (3), FRONTIER CALIFORNIA INC. (2), LEVEL 3 TELECOM OF CALIFORNIA, LP - CA (1). The earliest assignment on record here is 2010-09-08 and the most recent 2016-08-22. 6 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.
