CHARITON prefixes in area code 641

NANPA records 5 assigned NXX blocks to rate center CHARITON in area code 641, 0.9% of the 584 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 WINDSTREAM IOWA COMMUNICATIONS, INC. (2), UNITED STATES CELLULAR - IA (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IA (1). The earliest assignment on record here is 2001-02-14 and the most recent 2022-03-25. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
