History of Area Code 816
Area code 816 is one of the original North American area codes created in 1947. It originally covered a much larger part of northern and western Missouri. Over time, population growth and rising demand for telephone numbers reduced its footprint.
In 1997, Missouri created area code 660 from the eastern and southern parts of 816. That split left 816 serving the Kansas City and St. Joseph area in northwestern Missouri. In 2023, regulators approved an overlay for the region because the supply of available 816 numbers was running low, and area code 975 began service in 2023 as the overlay.
