History of 517 Area Code
Area code 517 was created in 1947 as one of Michigan’s three original area codes, along with 313 and 616. It serves the south-central part of Michigan’s Lower Peninsula, including Lansing and nearby communities. For over fifty years, 517 was the main code for this region.
In 2001, the northern and central parts of the 517 area were split off to form area code 989, while 517 continued to cover Lansing and the southern portion. Today, Michigan has 12 to 13 area codes, and 517 still identifies the south-central region, connecting residents and businesses across the area.
