PIXLEY prefixes in area code 559

NANPA records 4 assigned NXX blocks to rate center PIXLEY in area code 559, 0.5% 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. 3 holders hold those blocks, the largest being ONVOY, LLC - CA (2), LEVEL 3 TELECOM OF CALIFORNIA, LP - CA (1), PACIFIC BELL (1). 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
