Map of area code 989 in Michigan.

989 is the area code for Central Michigan, the northeastern Lower Peninsula, and portions of the Thumb. It is the highest-numbered area code in use in the North American Numbering Plan (NANP),[1] as well as the highest possible under the current system, in which a middle digit of 9 is forbidden.


Service areaEdit


The 989 region split off from area code 517 in 2001. Before then, 517 had served most of the eastern half of the Lower Peninsula (except the southeast) for 54 years and had been the only one of Michigan's three original area codes to have never been split.


Area code 989 is used for the sending of telexes to Marine City, Michigan.[citation needed]
