FORT DODGE prefixes in area code 515

NANPA records 14 assigned NXX blocks to rate center FORT DODGE in area code 515, 2.4% of the 578 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 FRONTIER COMMUNICATIONS OF IOWA, INC. (4), ONVOY, LLC - IA (2), UNITED STATES CELLULAR - IA (2). The earliest assignment on record here is 2001-06-05 and the most recent 2023-06-26. 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
