ALPAUGH prefixes in area code 559

NANPA records 4 assigned NXX blocks to rate center ALPAUGH 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 LEVEL 3 COMMUNICATIONS, LLC - CA (2), U.S. TELEPACIFIC CORP. DBA TPX COMMUNICATIONS (1), FRONTIER CALIFORNIA INC. (1). The earliest assignment on record here is 2006-12-14 and the most recent 2006-12-14. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
