HOUGHTONLK prefixes in area code 989

NANPA records 7 assigned NXX blocks to rate center HOUGHTONLK in area code 989, 1.0% of the 723 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. 6 holders hold those blocks, the largest being FRONTIER NORTH, INC. - MI (2), LEVEL 3 COMMUNICATIONS, LLC - MI (1), BANDWIDTH.COM CLEC, LLC - MI (1). The earliest assignment on record here is 2001-10-17 and the most recent 2018-06-25. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
