BIGBEAR LK prefixes in area code 909

NANPA records 8 assigned NXX blocks to rate center BIGBEAR LK in area code 909, 1.0% 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. 6 holders hold those blocks, the largest being ONVOY, LLC - CA (2), FRONTIER CALIFORNIA INC. (2), LEVEL 3 COMMUNICATIONS, LLC - CA (1). The earliest assignment on record here is 2012-08-06 and the most recent 2021-10-28. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
