RUSH CITY prefixes in area code 320

NANPA records 8 assigned NXX blocks to rate center RUSH CITY in area code 320, 1.6% of the 511 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 ONVOY, LLC - MN (4), BANDWIDTH.COM CLEC, LLC - MN (3), QWEST CORPORATION (1). The earliest assignment on record here is 2006-07-14 and the most recent 2022-01-27. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
