History of 660 Area Code
The 660 area code was established on October 12, 1997, after splitting from the 816 area code to meet the growing demand for phone numbers in northern and western Missouri. Before the split, the 816 area code covered a much larger portion of northern Missouri. After the division, 816 continued serving the Kansas City metropolitan area and nearby regions, while 660 was assigned to cover the surrounding northern and western parts of Missouri, helping balance number allocation across the state.
