LEBEC prefixes in area code 661

NANPA records 8 assigned NXX blocks to rate center LEBEC in area code 661, 1.2% 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. 5 holders hold those blocks, the largest being PACIFIC BELL (3), LEVEL 3 COMMUNICATIONS, LLC - CA (2), BANDWIDTH.COM CLEC, LLC - CA (1). 8 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
