Area code 620 serves southern and western Kansas, including cities such as Hutchinson, Dodge City, Garden City, and Parsons. It was created in 2001 from a split of area code 316, which retained coverage of the Wichita metropolitan area. The 620 region is primarily rural and agricultural, supporting industries such as farming, ranching, and food processing. The area also includes historic frontier towns and scenic landscapes. While population density is lower than urban areas, 620 is essential for connecting smaller communities across the vast expanse of Kansas. It remains a standalone area code with no overlays, reflecting the region’s steady but manageable growth.
