MTPLEASANT prefixes in area code 989

NANPA records 27 assigned NXX blocks to rate center MTPLEASANT in area code 989, 3.7% 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. 12 holders hold those blocks, the largest being FRONTIER NORTH, INC. - MI (6), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (5), NEW CINGULAR WIRELESS PCS, LLC - IL (4). The earliest assignment on record here is 2001-01-25 and the most recent 2023-06-09. 15 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 319, 430, 435, 662 – overlay codes cover the same geography, so a rate center is served by all of them.
