COTONWDFLS prefixes in area code 620
NANPA records 3 assigned NXX blocks to rate center COTONWDFLS 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 UNITED STATES CELLULAR - KS (1), SOUTHWESTERN BELL (1), ONVOY, LLC - KS (1). The earliest assignment on record here is 2003-11-26 and the most recent 2020-10-02. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
