TOWER prefixes in area code 218

NANPA records 3 assigned NXX blocks to rate center TOWER in area code 218, 0.4% 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. 3 holders hold those blocks, the largest being ONVOY, LLC - MN (1), TON80 COMMUNICATIONS, LLC (1), CITIZENS TELECOM CO MN-FRONTIER CITIZENS COM-MN (1). The earliest assignment on record here is 2014-10-15 and the most recent 2022-02-28. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
