CHISHOLM prefixes in area code 218

NANPA records 5 assigned NXX blocks to rate center CHISHOLM in area code 218, 0.7% of the 708 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 QWEST CORPORATION (1), ONVOY, LLC - MN (1), LEVEL 3 COMMUNICATIONS, LLC - MN (1). The earliest assignment on record here is 2003-09-24 and the most recent 2022-02-24. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
