Area code 517 is one of the original area codes established in 1947. It originally served the entire state of Michigan. In 2002, area code 989 was created as an overlay for area code 517.

Despite the overlay, area code 517 remains an important area code in Michigan. It serves the Lansing and Jackson metropolitan areas, as well as the rest of the state outside of the Detroit and Grand Rapids metropolitan areas.
