LTL CHUTE prefixes in area code 920

NANPA records 7 assigned NXX blocks to rate center LTL CHUTE in area code 920, 0.9% of the 785 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 ONVOY, LLC - WI (3), WISCONSIN BELL INC (2), BANDWIDTH.COM CLEC, LLC - WI (1). The earliest assignment on record here is 2010-11-04 and the most recent 2023-12-12. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
