BKFD SOUTH prefixes in area code 661
NANPA records 50 assigned NXX blocks to rate center BKFD SOUTH in area code 661, 7.4% of the 674 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. 13 holders hold those blocks, the largest being PACIFIC BELL (17), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (10), BANDWIDTH.COM CLEC, LLC - CA (6). The earliest assignment on record here is 2001-03-01 and the most recent 2026-09-25. 37 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
