FAIRVIEW prefixes in area code 989

NANPA records 3 assigned NXX blocks to rate center FAIRVIEW 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), CHARTER IP ENABLED SERVICES, LLC (1), FRONTIER NORTH, INC. - MI (1). The earliest assignment on record here is 2001-11-01 and the most recent 2021-05-13. 2 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 304, 309, 406, 417 – overlay codes cover the same geography, so a rate center is served by all of them.
