Area code 231

Map of area code 231 in Michigan.

231 is a North American telephone area code in the U.S. state of Michigan. Area Code 231 includes the Northwestern part of Michigan's Lower peninsula. Areas included are Muskegon, Petoskey, Ludington, Baldwin, Traverse City, and Pentwater. It was created in June 1999 as a split from area code 616. 231 is essentially the northern half of the old 616 area code. 616 previously covered the entire western half of the state of Michigan, extending west from the north-south line aligned with the Mackinac Bridge.

The new 231's southern boundary closely follows the county lines between Muskegon County, Ottawa County, Kent County, and Montcalm County.

Among the Michigan cities it serves are Big Rapids, Cadillac, Grant, Kalkaska, Ludington, Manistee, Muskegon, Petoskey, Newaygo, and Traverse City.
