How Many Area Codes Are in Kansas? The Short Answer
Kansas currently has 4 active area codes in service. The count reflects a combination of population growth, the rise of mobile lines, and the way modern numbering allocates blocks — every line activated, whether a cellphone, a business desk line, a VoIP number, or a connected device, consumes a slot in the pool.
By population, Kansas ranks #35 nationally with roughly 2,970,606 residents as of the most recent estimates. That puts the state’s area code count in line with its population peers — denser, faster-growing states need more codes; smaller states need fewer.

How Kansas’s Area Codes Grew Over Time
Kansas was assigned 2 area codes in the original 1947 NANP launch — 316, 913 — reflecting the state’s population and territorial size at the time. Subsequent splits and overlays have added codes as demand has grown.
- 1947 — Kansas was divided into two numbering plan areas at the launch of the North American Numbering Plan. 316 covered the southern half of the state (Wichita, Dodge City, Garden City, Emporia) and 913 covered the northern half (Kansas City, Topeka, Lawrence, Salina, Hays).
- 1997 — 785 split off from 913 on July 20, 1997, taking the northern Kansas territory outside the Kansas City metro area and leaving 913 with the eight-county Kansas City region.
- 2001 — 620 split off from 316 for southern Kansas outside Wichita, with permissive dialing of 316 across the new 620 territory ending November 3, 2001.
Kansas Area Codes by Region
Wichita and southern Kansas (316, 620): 316 serves the city of Wichita and its immediate surroundings as an enclave. 620 surrounds it, covering the rest of southern Kansas including Dodge City, Garden City, Hutchinson, and Emporia after splitting from 316 in 2001.
Kansas City metro and northern Kansas (913, 785): 913 serves the Kansas side of the Kansas City metropolitan area, including Overland Park, Olathe, and Kansas City, Kansas. 785 covers the rest of northern Kansas, including Topeka, Lawrence, Manhattan, Salina, and Hays, after splitting from 913 in 1997.
What’s Next for Kansas Area Codes
Kansas has not added a new area code since 620 in 2001, and all four of its codes are single geographic plan areas with no overlays. NANPA’s most recent NPA exhaust projections show no Kansas numbering plan area on the near-term relief schedule, reflecting the state’s slow population growth (about 2,970,606 residents in 2024). The Kansas City metro code 913 is the most heavily used and the most likely future pressure point, but no relief is currently projected for any Kansas code in the next several years.
