Kansas Area Codes

About Area Codes in Kansas

Kansas (KS) is the The Sunflower State, located in the Midwest region of the United States. With a 2023 population of 2,940,865 residents, Kansas is served by 4 active area codes. The state capital is Topeka and the largest city is Wichita.Kansas's official motto is "Ad astra per aspera."

Area code assignments in Kansas follow the North American Numbering Plan (NANP), which has been in effect since 1947. As the state's population and demand for phone numbers grew — driven by the rise of cell phones, fax machines, pagers, and VoIP lines — regulators either split existing area codes geographically or added overlay codes that share the same territory. That's why Kansas now has 4 codes: 316, 620, 785, 913.

When you receive a call from a Kansas number, the area code tells you only where the number was originally assigned. Because of Local Number Portability (LNP), which took effect in 2003, callers can keep their phone numbers even when moving across state lines. So while a 316 number was once assigned in Kansas, the person calling you could be anywhere in the US today.

Time zones in Kansas

Kansas observes the Central time zone. Daylight Saving Time is observed from the second Sunday in March through the first Sunday in November, when clocks shift forward by one hour. When you call a Kansas number from outside the state, double-check the local time above each area code detail page to avoid calling at unreasonable hours.

Phone number format in Kansas

All Kansas phone numbers follow the standard 10-digit NANP format: (NPA) NXX-XXXX. For local calls within Kansas, you typically need to dial the full 10-digit number — even for calls within the same area code — because of mandatory 10-digit dialing imposed by the FCC for areas with overlay codes (most of Kansas's territory). For long-distance calls within the NANP, dial 1 + area code + 7-digit number.
