OSAWATOMIE prefixes in area code 913

NANPA records 6 assigned NXX blocks to rate center OSAWATOMIE in area code 913, 1.1% of the 533 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 UNITED TEL. CO. OF KANSAS DBA CENTURYLINK (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - KS (2), CSC VOICE, LLC (1). The earliest assignment on record here is 2013-10-29 and the most recent 2024-10-16. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
