Introduction
Which area code contains the global headquarters of Garmin — the company that put GPS navigation into every pocket on earth — the former Sprint World Headquarters campus that became the focal point of the largest telecommunications merger in American history, and a $4 billion Panasonic battery plant that opened in 2025 to supply power cells for half a million electric vehicles per year?
The answer is 913 — the area code serving the Kansas side of the Kansas City metropolitan area.
Area code 913 covers northeast Kansas: Overland Park, Olathe, Shawnee, Lenexa, Leawood, Kansas City (Kansas), Leavenworth, and the corridor of eight counties hugging the Missouri state line. It is one of the original 1947 NANP area codes, and despite losing most of its geographic territory in a 1997 split, it held onto the most economically productive slice of the state.
This guide covers the full history, geography, economy, and business case for the 913 area code.

What Is the 913 Area Code?
The 913 area code is a geographic North American Numbering Plan (NANP) code serving northeastern Kansas, primarily the Kansas portion of the Kansas City metropolitan statistical area. Its numbering plan area (NPA) covers eight counties along the eastern border of Kansas adjoining Missouri.
Major communities served by the 913 area code include Overland Park (Johnson County seat; largest city in the 913 territory and second-most populous in Kansas), Olathe (global headquarters of Garmin International; fast-growing Johnson County city), Shawnee (western Johnson County community; major residential and commercial growth corridor), Lenexa (where Garmin was originally founded in 1989; active manufacturing and logistics hub), Leawood (affluent residential community; home of Black & Veatch global headquarters), Prairie Village, Merriam, Mission, and Roeland Park (established inner-ring Johnson County suburbs), Kansas City, Kansas (KCK, Wyandotte County seat; site of the planned Kansas City Chiefs domed stadium), Leavenworth (home of Fort Leavenworth, the US Army's oldest active installation west of the Mississippi), and Atchison (historic Missouri River town; birthplace of Amelia Earhart).
The entire 913 territory operates in the Central Time Zone (UTC−6 / UTC−5 CDT). All local calls require 10-digit dialing.
Businesses that want to activate service right away can start with local phone numbers.
The History of the 913 Area Code
The 913 area code's history is one of dramatic geographic contraction followed by economic concentration:
1947 — Area Code 913 covers all of northern Kansas: Under the original NANP assignment, 913 covers the entire northern tier of Kansas — from the Colorado state line all the way to the Missouri state line. This enormous territory includes Topeka, Salina, Manhattan, Hays, and the Kansas City suburbs.
July 20, 1997 — Area Code 785 splits from 913: Three decades of population growth and the mobile phone revolution strain the 913 number pool across Kansas. NANPA approves the creation of 785, which takes the vast majority of 913's territory — essentially all of Kansas except the eastern strip bordering Missouri.
Area code 913 loses Topeka, Salina, Manhattan, Hays, and every city west of the Kansas City suburbs.
Result: 913 shrank, but kept the economy. What remained after the 785 split was a narrow ribbon of eight counties along the Missouri border — but those eight counties contain the entirety of the Kansas City metro's Kansas side. The 913 area code lost roughly 85% of its geographic footprint and kept 100% of the state's most economically productive metropolitan zone.
No planned overlay or split is in the pipeline; NANPA projections estimate 913's number pool lasts until 2045.

| Area Code | Assigned | Type | Territory |
|---|---|---|---|
| 913 | 1947 | Original NANP — northern Kansas | All of northern Kansas (CO to MO border) |
| 785 | Jul 20, 1997 | Geographic split from 913 | Most of Kansas (Topeka, Salina, Manhattan, etc.) |
| 913 (current) | Post-1997 | Retained eastern strip | 8 counties of Kansas City metro KS side |
Garmin and Olathe: The Navigation Capital of America
No company in the 913 area code better illustrates how a Midwest suburban location can anchor a global technology enterprise than Garmin International.
Garmin was co-founded by Gary Burell and Min Kao in 1989 in Lenexa, Kansas — 913 territory. The company's first product was a handheld GPS receiver for aviation use; within a decade, Garmin had pivoted to automotive navigation and consumer GPS and was shipping the devices that replaced paper maps in millions of cars and pockets worldwide.
The company's global headquarters relocated to Olathe, Kansas — still in the 913 area code — where it remains today.
Garmin's Olathe campus is not a satellite office or a regional hub. It is the global headquarters of a company with more than $5 billion in annual revenue, designing GPS navigation, aviation electronics, marine instruments, cycling computers, and fitness wearables used in more than 100 countries.
For any vendor, supplier, or technology partner whose business touches Garmin's product lines or supply chain, the 913 area code is the expected return address on a calling card.
Adjacent to Garmin's supply chain, Olathe also hosts the University of Kansas Edwards Campus, bringing graduate and professional education directly into the 913 business corridor.
The Sprint Campus, T-Mobile, and the Fiserv Transformation
No single campus in the 913 area code has absorbed more corporate history per square foot than the former Sprint World Headquarters in Overland Park — and its next chapter is the most consequential yet.
Sprint Corporation built its global headquarters on a $4 billion campus in Overland Park designed to house more than 15,000 employees. In 2020, T-Mobile completed its $26.5 billion merger with Sprint — the largest transaction in US wireless carrier history.
T-Mobile maintained a continued Overland Park presence of approximately 5,000 employees.
The post-merger future of the former Sprint campus was uncertain until April 2025, when Fiserv announced a $175 million investment to redevelop 427,000 square feet of the former Sprint campus into a financial technology hub. Fiserv's project is projected to bring 2,000 new jobs paying an average of $100,000 and generate a $6.5 billion economic impact over ten years, with the hub opening in two phases beginning in 2026.
Black & Veatch, the global engineering, procurement, and construction firm, also maintains its global headquarters in Leawood, Kansas — contributing additional Fortune 500-caliber commercial activity to the Johnson County 913 economy.
Panasonic, the Chiefs, and Kansas's Economic Inflection Point
Two announcements within months of each other have made 2025 and 2026 the most economically significant period in Kansas history — and both landed in the 913 area code.
Panasonic Energy EV Battery Plant, De Soto. On July 14, 2025, Panasonic Energy opened its $4 billion electric vehicle battery manufacturing facility in De Soto, Johnson County — 913 territory. The plant spans 300 acres and is designed to produce 30 GWh of cylindrical lithium-ion batteries annually — enough to supply power cells for approximately 500,000 electric vehicles per year.
Once fully ramped, the facility will support approximately 4,000 direct jobs, with total employment impact reaching 8,000 when supply chain and service providers are included.
Kansas City Chiefs Domed Stadium, Kansas City, Kansas. In December 2025, the Kansas City Chiefs and Kansas Governor Laura Kelly announced an agreement to build a $3 billion domed stadium in Wyandotte County, Kansas — in the Kansas City, Kansas portion of the 913 area code — adjacent to Kansas Speedway and The Legends retail district. The stadium is scheduled to open in 2031.
The Chiefs' training facility and headquarters will be located in Olathe — also 913.
Why Businesses Choose a 913 Area Code Number
For companies targeting the Kansas City metro's Kansas side — whether in financial technology, GPS and aviation electronics, healthcare IT, engineering consulting, EV supply chain, or the stadium-driven hospitality and construction corridor — a 913 number signals embedded market presence that national toll-free numbers cannot replicate.
Financial Technology. With Fiserv's 2,000-job hub coming online on the former Sprint campus in 2026, Overland Park is establishing itself as a financial technology cluster. Payment processing, compliance technology, banking software, and enterprise workflow vendors serving this corridor need local credibility.
EV and Advanced Manufacturing Supply Chain. Panasonic's De Soto plant creates immediate demand for materials suppliers, logistics providers, precision manufacturing vendors, engineering consultants, and workforce services companies. A 913 number positions EV supply chain vendors as regional partners rather than out-of-state solicitors.
Defense and Government. Fort Leavenworth operates in the 913 territory, creating sustained defense contracting, legal, and professional services demand. Pair that local credibility with Teloz's AI-driven routing, omnichannel communication, CRM integration, and real-time analytics, and your Kansas City metro operation runs at enterprise scale from launch.

How to Get a 913 Area Code Number
Here is the six-step process for establishing a 913 northeast Kansas number for your business.
If your team also needs multi-region reach, compare international virtual numbers.
Step 1: Confirm Number Availability
Work with a cloud VoIP provider holding active 913 Kansas inventory. 913 has no planned overlay until at least 2045, so number availability is stable — but confirm the 913 prefix specifically for your Johnson County or Wyandotte County market identity.
Step 2: Choose Your Number Format
Select a standard 913 local DID or a vanity number reflecting your market position — for example, a Garmin supply chain vendor, a financial technology firm serving the Fiserv hub, or an EV supply chain company serving the Panasonic De Soto plant.
Step 3: Configure Market-Specific Routing
Build IVR queues for your key 913 market segments: financial technology, defense/government, EV manufacturing, healthcare IT, or stadium construction corridor — with skills-based routing directing each caller to the right team.
Step 4: Integrate Your CRM
Link every 913 inbound and outbound call to your CRM automatically. In the Kansas City metro's B2B professional services economy, documented contact history is a competitive differentiator in long-cycle enterprise relationships.
Step 5: Verify 10-Digit Caller ID
Confirm your outbound 913 caller ID displays the full 10-digit number before going live, ensuring correct identification across the 913/816 metro split.
Step 6: Monitor with Real-Time Analytics
Track answer rates, campaign performance, handle times, and first-contact resolution from live dashboards from day one.
Conclusion
The 913 area code's history is a lesson in how economic value concentrates: a code that once spanned all of northern Kansas lost most of its territory in 1997 and emerged stronger, retaining the Kansas City metro's Kansas side — where Garmin built a $5 billion global technology company, Sprint built and T-Mobile absorbed a telecom empire, Fiserv is building the region's next financial technology hub, and Panasonic opened the largest industrial investment in Kansas history in 2025.
Add the Kansas City Chiefs' $3 billion domed stadium coming to Wyandotte County in 2031, and the 913 area code is entering a period of economic transformation with few parallels in the Midwest. See how Teloz powers your northeast Kansas market presence at teloz.com.
