GLENNIE prefixes in area code 989

NANPA records 3 assigned NXX blocks to rate center GLENNIE in area code 989, 0.4% 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. 3 holders hold those blocks, the largest being INTERACTIVE SERVICES NETWORK, INC. (1), BRIGHTSPEED OF MICHIGAN, LLC (1), TON80 COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2004-03-24 and the most recent 2022-03-03. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
