BRBN SNVY prefixes in area code 818

NANPA records 16 assigned NXX blocks to rate center BRBN SNVY in area code 818, 2.0% 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. 9 holders hold those blocks, the largest being PACIFIC BELL (6), T-MOBILE USA, INC. (3), TELEPORT COMMUNICATIONS AMERICA, LLC - CA (1). The earliest assignment on record here is 2002-02-13 and the most recent 2024-06-21. 13 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.
