History of Area Code 660
Area code 660 was created on June 12, 1997, and entered service on October 12, 1997. It was formed through a geographic split from area code 816, which had previously covered Kansas City and much of northern and west-central Missouri.
The split gave communities outside the Kansas City area a separate numbering plan as demand for telephone numbers increased. Area code 660 has no overlay, and no additional split has been assigned to it.
