CEDAR VALE prefixes in area code 620

NANPA records 3 assigned NXX blocks to rate center CEDAR VALE in area code 620, 0.4% 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. 3 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (1), LEVEL 3 COMMUNICATIONS, LLC - KS (1), SOUTHWESTERN BELL (1). The earliest assignment on record here is 2002-12-30 and the most recent 2004-03-09. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
