KEWANEE prefixes in area code 309

NANPA records 13 assigned NXX blocks to rate center KEWANEE in area code 309, 1.7% of the 786 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. 6 holders hold those blocks, the largest being FRONTIER NORTH, INC. - IL (5), ONVOY, LLC (2), T-MOBILE USA, INC. (2). The earliest assignment on record here is 2001-05-21 and the most recent 2023-02-07. 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
