CHERRYVALE prefixes in area code 620

NANPA records 5 assigned NXX blocks to rate center CHERRYVALE in area code 620, 0.7% of the 705 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. 4 holders hold those blocks, the largest being SOUTHWESTERN BELL (2), TELEPORT COMMUNICATIONS AMERICA, LLC - KS (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2001-06-08 and the most recent 2010-03-02. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
