What are the 517 Area Code Phone Numbers?

Area code 517, created as one of the original area codes on January 1, 1947, initially covered the eastern half of Michigan's Lower Peninsula, excluding the southeast, which later became area code 313. This area code serves south-central Michigan in the Eastern time zone. This area code covers cities such as Lansing, East Lansing, Jackson, Charlotte, Albion, Coldwater, and numerous smaller cities. Along with the tri-cities of Saginaw, Midland, and Bay City, as well as much of Mid-Michigan, on April 7, 2001, the northern and central segments of the old 517 territory turned into area code 989. Area code 517 is important for supporting communication services for businesses and residents. Leading institutions in this region, including the Michigan State Capitol in Lansing, Michigan State University in East Lansing, and Consumers Energy’s headquarters in Jackson, drive the local economy by providing job opportunities and supporting economic growth and development. The nearby area codes include 989 to the north and 734 to the southeast, ensuring efficient communication and strong connectivity for businesses and residents in the region. The economic landscape in this region is diverse, with Lansing excelling in government and education, East Lansing leading in research and innovation, and Jackson playing a central role in energy production and manufacturing.
