NICOLLET prefixes in area code 507

NANPA records 4 assigned NXX blocks to rate center NICOLLET in area code 507, 0.5% of the 766 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 QWEST CORPORATION (1), BANDWIDTH.COM CLEC, LLC - MN (1), ONVOY, LLC - MN (1). The earliest assignment on record here is 2018-05-11 and the most recent 2023-06-21. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
