BASEHOR prefixes in area code 913

NANPA records 6 assigned NXX blocks to rate center BASEHOR 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. 5 holders hold those blocks, the largest being SOUTHWESTERN BELL (2), NUSO, LLC (1), ONVOY, LLC - KS (1). The earliest assignment on record here is 2001-06-21 and the most recent 2022-08-25. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
