BRBN BRBN prefixes in area code 818

NANPA records 88 assigned NXX blocks to rate center BRBN BRBN in area code 818, 11.3% of the 781 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. 14 holders hold those blocks, the largest being PACIFIC BELL (33), T-MOBILE USA, INC. (15), NEW CINGULAR WIRELESS PCS, LLC (11). The earliest assignment on record here is 2001-04-12 and the most recent 2014-06-13. 48 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 747 – overlay codes cover the same geography, so a rate center is served by all of them.
