CONKLIN prefixes in area code 616

NANPA records 3 assigned NXX blocks to rate center CONKLIN in area code 616, 0.6% of the 545 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 TON80 COMMUNICATIONS, LLC (1), ONVOY, LLCV - MI (1), FRONTIER NORTH, INC. - MI (1). The earliest assignment on record here is 2016-06-30 and the most recent 2022-03-07. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
