OSAGE CITY prefixes in area code 785

NANPA records 4 assigned NXX blocks to rate center OSAGE CITY in area code 785, 0.6% of the 726 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 LEVEL 3 COMMUNICATIONS, LLC - KS (2), ONVOY, LLC - KS (1), UNITED TEL OF EASTERN KANSAS DBA CENTURYLINK (1). The earliest assignment on record here is 2004-04-06 and the most recent 2021-04-06. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
