Map of Kansas with area code 620 in red

Area Code 620 covers telephone exchanges in most of southern Kansas. It was created as the result of a split from 316 on February 3, 2001. The area code stretches from the Colorado border to the east, to the Missouri border. It completely surrounds 316, which now only serves Wichita and its inner suburbs. Permissive dialing of 316 across southern Kansas continued until November 3, 2001.

The most populous cities covered by the area code are Dodge City, Garden City, and Hutchinson.

620 was created due to the growing proliferation of cell phones in the Wichita area. With the great majority of the old 316's landlines and cell phones located in the Wichita area, 620 is one of the most thinly populated area codes in the nation. Under the most recent projections, southern Kansas will not need another area code until 2035.[1]

Boundaries of area code 620[edit]

The boundary between area codes 620 and 785 runs from west to east roughly following a path along K-4 and K-96. The code boundary dips along I-135 in McPherson County and continues east to just north of Emporia in Lyon County along the Kansas Turnpike, where the boundaries of area codes 620, 785 and 913 meet. Area code 620 shares its northern boundary with area code 913's southern boundary, ending south of the Kansas City metropolitan area.

All of Sedgwick County, along with parts of Butler, Harvey, Kingman, Reno and Sumner counties, remain in area code 316.
