Area code 620 — Southern Kansas telephone area code
Area code 620 serves most of southern Kansas. Created in 2001 from a split of 316, it spans the state from the Colorado to Missouri borders and surrounds the Wichita metro.
Area code 620 is a North American Numbering Plan (NANP) telephone area code that covers a broad swath of southern Kansas. It was introduced in early 2001 as part of a reorganization of the numbering plan for the region. The change redistributed numbering resources to accommodate growing demand for telephone lines, cellular service, and other communications services.

Coverage and boundaries
The 620 area stretches across the state from the western border with Colorado to the eastern border with Missouri, encompassing many small cities, towns, and rural exchanges. It surrounds but does not include the Wichita metropolitan area, which retained the separate area code 316. Area code boundaries are determined by telecommunications authorities and often cross county lines rather than following political borders.
Communities served by 620 include several regional centers and numerous smaller communities. Examples of cities and towns within the code's territory include Dodge City, Hutchinson, Liberal, Parsons and Emporia, among others. Because of its size, 620 contains a mix of agricultural, industrial and regional service centers.
History and administration
Area code 620 went into effect when it was split from area code 316 on February 3, 2001. The split was enacted to relieve number exhaustion as demand for new telephone numbers increased. Assignments and changes to area codes and central office codes are managed under the NANP and by national and regional numbering administrators.
Uses and practical notes
Like other area codes, 620 is used to route telephone calls, identify the general origin of a number within the NANP, and support billing and network management. Businesses and residents often use the area code in marketing and local branding. Dialing procedures (seven- or ten-digit local dialing) depend on regional dialing plans and any overlays or regulatory changes in effect.
Notable distinctions: 620 is notable for encircling the smaller 316 territory that serves Wichita, creating a geographic relationship sometimes described as a "doughnut" split. Because area codes are administrative designations, they do not always align with local identity or municipal boundaries, but they remain an important part of telecommunications infrastructure.
