AVENAL prefixes in area code 559

NANPA records 7 assigned NXX blocks to rate center AVENAL in area code 559, 0.9% of the 785 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 BANDWIDTH.COM CLEC, LLC - CA (2), AT&T ENTERPRISES, LLC (1), PACIFIC BELL (1). The earliest assignment on record here is 2009-12-14 and the most recent 2018-02-23. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
