Area code 517 serves south-central Michigan, including Lansing (the state capital), East Lansing, Jackson, and nearby communities. Established in 1947 as one of Michigan’s original area codes, 517 remains a core identifier for the state’s political and academic institutions. Lansing is the seat of Michigan’s government and home to many state agencies and offices. East Lansing houses Michigan State University, one of the largest public universities in the U.S., contributing significantly to education, research, and local employment. The surrounding region includes both urban and rural areas with a strong presence in manufacturing, automotive supply chains, healthcare, and agriculture. A 517 number adds credibility across Michigan’s capital region and is ideal for businesses that interact with government agencies, serve university communities, or provide services in a mixed industrial and educational environment.
