ALMONT prefixes in area code 810

NANPA records 3 assigned NXX blocks to rate center ALMONT in area code 810, 0.6% of the 509 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 BANDWIDTH.COM CLEC, LLC - MI (1), TELEPORT COMMUNICATIONS AMERICA, LLC - MI (1), FRONTIER NORTH, INC. - MI (1). The earliest assignment on record here is 2019-05-17 and the most recent 2019-05-17. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
