REEDLEY prefixes in area code 559

NANPA records 13 assigned NXX blocks to rate center REEDLEY in area code 559, 1.7% 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. 7 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (4), FRONTIER CALIFORNIA INC. (3), T-MOBILE USA, INC. (2). The earliest assignment on record here is 2002-01-29 and the most recent 2025-01-02. 11 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
