What Is the 913 Area Code?

The 913 area code is a telephone area code for the Kansas side of the Kansas City metropolitan area. Originally established in 1947 as one of the original North American area codes, 913 once covered the entire state of Kansas. As population grew, the 316 code was split off for Wichita in 1957, and 785 was created in 1997 for Topeka and rural Kansas — leaving 913 as the code for the Kansas City Kansas suburbs, primarily Johnson and Wyandotte counties.

Key facts about 913:

• State: Kansas
• Coverage: Johnson County (Overland Park, Olathe, Lenexa, Shawnee, Leawood), Wyandotte County (Kansas City, KS), Leavenworth County
• Time Zone: Central Time (CT) — UTC-6 / UTC-5 DST
• Overlay: None — 913 is the sole area code for this region
• Related codes: 816 (Kansas City, MO — Missouri side), 785 (Topeka and central/western Kansas)
• Introduced: 1947 (one of the original US area codes)
• Significance: Wealthiest county in Kansas, T-Mobile HQ, major corporate campuses

913 is the sole area code for the Kansas suburbs of Kansas City. There is no overlay, which means a 913 number unambiguously identifies your business as Johnson County or KCK — the most affluent and commercially active region in Kansas.

The 913 area code is located in northeastern Kansas, covering the Kansas side of the Kansas City metropolitan area — primarily Johnson County, Wyandotte County, and parts of Leavenworth County.

Johnson County–Specific Considerations

The State Line Factor

The Kansas City metro is split by the Kansas-Missouri state line, and the 913/816 divide follows it precisely. Businesses on the Kansas side that display Missouri 816 numbers risk being perceived as outsiders by Johnson County residents — and vice versa. If your customers are in Overland Park, Olathe, or Lenexa, you need a 913 number. VestaCall lets you maintain numbers on both sides of the state line if you serve the entire KC metro — a 913 number for Kansas clients and an 816 for Missouri clients, all managed from a single dashboard.

T-Mobile and the Tech Ecosystem

The former Sprint Campus — now T-Mobile’s headquarters — is the largest single-building office complex in Kansas. This facility and the broader telecom ecosystem it supports have made Overland Park a major tech hub. Companies building products, services, or integrations for the telecom industry are concentrated in the 913 area and need local numbers that match the ecosystem they’re selling into.

Panasonic and the EV Boom

Panasonic’s massive electric vehicle battery manufacturing plant in De Soto (Johnson County) is one of the largest industrial investments in Kansas history. The facility is driving an influx of suppliers, contractors, and support businesses to the 913 area. These companies need local phone numbers immediately — VestaCall delivers a 913 number in minutes, not weeks.

Severe Weather Resilience

Kansas is in Tornado Alley, and Johnson County experiences severe thunderstorms, tornadoes, and ice storms. A traditional on-premise PBX can be knocked offline by a direct hit or a power grid failure. VestaCall’s cloud infrastructure with automatic mobile failover keeps your 913 line operational even when your office is without power. Your team takes calls on the mobile app, and callers never know the difference.

Cross-Metro Business Operations

Many Kansas City area businesses operate on both sides of the state line. A law firm might have offices in Overland Park (913) and downtown Kansas City, MO (816). A healthcare system might have clinics across both states. VestaCall’s unified platform lets you manage 913 and 816 numbers from a single account with shared directories, call routing, and analytics — eliminating the need for separate phone systems on each side of the state line.
