📍 Geographic Location of Kansas
Geographic Coverage and Jurisdiction
Area code 316 is a geographic North American Numbering Plan Area (NPA) serving the south-central region of Kansas, United States. It is administered under the jurisdiction of the Kansas Corporation Commission. The code primarily covers Sedgwick County, including the city of Wichita, the largest city in Kansas, along with surrounding communities such as Derby, Haysville, Park City, Valley Center, and Maize. The numbering plan area also extends into portions of Butler, Harvey, and Sumner counties, providing coverage to towns like El Dorado, Newton, and Wellington.
Dialing Formats and Procedures
Within the 316 area code, local calls are placed using the 7-digit subscriber number. However, due to the introduction of an overlay, all calls within the region require 10-digit dialing (area code + 7-digit number). This applies to both local and toll calls. For callers from outside the 316 area code but within the United States or Canada, the international format is 1-316-XXX-XXXX. For international callers, the format is +1-316-XXX-XXXX, where the plus sign represents the international access prefix (e.g., 011 from many countries).
Overlay and Numbering Resources
In 2021, the Kansas Corporation Commission approved an overlay plan for area code 316, introducing a second area code, 748, to the same geographic region. This overlay ensures a continued supply of telephone numbers without requiring existing customers to change their numbers. As a result, new telephone lines in the region may be assigned either 316 or 748 area codes. All calls between these codes are local and require 10-digit dialing.
Service and Usage
Area code 316 serves a mix of residential, business, and government customers. It hosts major industries including aviation (with companies like Textron Aviation and Spirit AeroSystems), healthcare, and education (Wichita State University). The region is well-served by multiple carriers, including AT&T, Verizon, T-Mobile, and various VoIP providers. Number portability allows customers to retain their 316 numbers when switching carriers, even if they move within the service area.
Caller Instructions
For local callers within 316: dial 316-XXX-XXXX for all calls, including those to neighboring area codes 620 and 785. For long-distance callers within the U.S.: dial 1-316-XXX-XXXX.
