ALMA prefixes in area code 989

NANPA records 16 assigned NXX blocks to rate center ALMA in area code 989, 2.2% 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. 10 holders hold those blocks, the largest being FRONTIER NORTH, INC. - MI (5), LEVEL 3 COMMUNICATIONS, LLC - MI (3), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2001-11-30 and the most recent 2021-05-24. 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 308, 479, 608, 660 – overlay codes cover the same geography, so a rate center is served by all of them.
