KEOKUK prefixes in area code 319

NANPA records 9 assigned NXX blocks to rate center KEOKUK in area code 319, 1.6% of the 565 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 QWEST CORPORATION (2), LOCAL TELEPHONE DATA SERVICES CORP. (1), T-MOBILE USA, INC. (1). The earliest assignment on record here is 2001-05-30 and the most recent 2022-03-24. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
