Area code 816
Area Code 816 is the area code for most of northwestern Missouri; it includes the Kansas City Metropolitan Area, and the city of St. Joseph to the north. This area code originally covered the entire northwestern quadrant of Missouri, including its borders with Iowa, Kansas, and Nebraska, but has been reduced so that only Kansas borders 816. Within Missouri, 816 borders only area code 660, the latter being a relief code when 816 was nearing exhaustion.
History of area codes in Missouri
When the North American Numbering Plan was created in 1947, Missouri was divided into two numbering plan areas (NPAs). Area code 816 served all points west of Jefferson City, while area code 314 served the east, including St. Louis. In 1951 a third NPA with area code 417, was split off from its southwest, including the cities of Branson, Joplin, and Springfield.
By late 1996 the proliferation of cell phones, especially in the Kansas City area, and other market reforms related to deregulation by the Telecommunications Act of 1996, required that northwestern Missouri received an additional area code. The supply of telephone numbers was further limited because the Kansas City LATA extends some distance into eastern Kansas, meaning that several numbers in area code 913, the area code for most of the Kansas side of the Kansas City area, were not available for use.
In early 1997, the Missouri Public Service Commission, which oversees telecommunications in the state, held hearings regarding a possible split of the area code. The original recommendation of the Missouri PSC was to assign a new area code, 660, to the eastern and northwestern portions of the 816 territory, to cause the least disruption. Generally, St. Joseph and metropolitan Kansas City were left in 816. Two notable exceptions were Lexington and Warrensburg, which were included in 660 even though they are generally considered as part of the Kansas City area.
On June 4, 1997, the Missouri PSC announced the commencement of a permissive dialing period for those areas, starting on October 12, 1997, meaning that calls could be completed using either area code 660 or 816. On April 19, 1998, 660 became mandatory for all calls in the affected area.
In 2000, the Missouri PSC announced plans to add 975 as an overlay to the 816 area code, but postponed the May 5, 2002 implementation date, when the commission determined no immediate need for additional phone numbers.
