IOWA FALLS prefixes in area code 641
NANPA records 8 assigned NXX blocks to rate center IOWA FALLS in area code 641, 1.4% 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. 8 holders hold those blocks, the largest being ONVOY, LLC - IA (1), COMMIO, LLC (1), UNITED STATES CELLULAR - IA (1). The earliest assignment on record here is 2002-07-16 and the most recent 2025-08-27. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
