It was created in 1999 as a split from Area code 616, which serves the southern and central parts of western Michigan, including the cities of Grand Rapids and Holland. The area code is also close to the Lake Michigan shoreline, which includes popular tourist destinations like Sleeping Bear Dunes National Lakeshore and Petoskey.
