Michigan, the Great Lakes State, is famed for its automotive legacy, freshwater coastlines, and resilient Midwestern spirit. The state features two peninsulas—the industrialized Lower Peninsula and the forested Upper Peninsula—linked by the iconic Mackinac Bridge. Detroit, once the heart of American car manufacturing, is undergoing a cultural and economic renaissance.

Originally assigned area code 313, Michigan’s telecom structure expanded to include 248, 586, 734, 810, 989, 906, 231, 616, 517, 269, and overlays like 947. Metro Detroit uses multiple overlapping area codes, while regions like the Upper Peninsula rely on single codes like 906. These Michigan area codes support a diverse state economy that includes manufacturing, healthcare, and tourism.
