CABOOL prefixes in area code 417

NANPA records 3 assigned NXX blocks to rate center CABOOL in area code 417, 0.4% of the 711 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. 3 holders hold those blocks, the largest being UNITED STATES CELLULAR - MO (1), FRACTEL, LLC (1), BRIGHTSPEED OF MISSOURI, LLC (1). The earliest assignment on record here is 2019-12-05 and the most recent 2019-12-05. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
