Area code 913 is the telephone area code in the North American Numbering Plan for northeastern Kansas. The numbering plan area (NPA) consists of a small ribbon of eight counties bordering Missouri, an area largely coextensive with the Kansas portion of the Kansas City Metropolitan Area.
Prior to July 20, 1997, numbering plan area 913 comprised all of northern Kansas from the Colorado state line to the Missouri state line, running along the entire border with Nebraska.
