OSAGE prefixes in area code 641

NANPA records 4 assigned NXX blocks to rate center OSAGE in area code 641, 0.7% 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. 4 holders hold those blocks, the largest being FRACTEL, LLC (1), ONVOY, LLC - IA (1), QWEST CORPORATION (1). The earliest assignment on record here is 2002-05-07 and the most recent 2019-12-27. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 218, 870, 918 – overlay codes cover the same geography, so a rate center is served by all of them.
