913 Area Code: Kansas City, Kansas — Cities, Nearby Codes & Business Guide

The 913 area code is the telephone signature of the Kansas side of the Kansas City metro — the affluent, fast-growing half of a region that famously straddles a state line.

Where its neighbor across the border carries the older Missouri core, 913 rings in the Johnson County suburbs and the Wyandotte County riverfront: the corporate campuses of Overland Park, the technology headquarters of Olathe, and the historic neighborhoods of Kansas City, Kansas. For a business, a 913 number reads instantly as the Kansas side of the metro — a distinction locals catch before the call is even answered.

Because the metro is split by a state line rather than a river, the three digits at the front of a number reveal which state a caller sits in, and 913 has meant Kansas since the first year of the numbering plan.

This guide covers where the code applies today, the cities that define it, why it remains one of the rare major-metro codes with no overlay, which codes border it, the corporate economy behind it, and the exact steps to activate a 913 number from anywhere.

The 913 area code serves the Kansas portion of the Kansas City metropolitan area — a ribbon of counties along the Missouri border in the northeastern corner of the state. It was put into service in 1947 as one of the original 86 area codes of the North American Numbering Plan, and at first it covered the entire northern half of Kansas.

Explosive suburban growth in Johnson County exhausted its supply of numbers by the mid-1990s, and in 1997 the territory was split: everything from Lawrence westward became the new 785 area code, while 913 was concentrated on the Kansas City metro it still serves today.

Dialing Format and Time Zone

• Dialing format: (913) 555-0123
• International: +1 913-555-0123
• Time zone: Central Time (CT), UTC−6 Standard, UTC−5 Daylight Saving
• Year introduced: 1947 — one of the original 86 codes, reduced to the KC metro in the 1997 split

The two-state geography makes the prefix unusually informative. Because a state line rather than a landmark divides the metro, the leading digits of a phone number reveal which side of the border a caller is on — a difference that touches everything from tax jurisdictions to school districts to sports loyalties. Locals read it instantly, which is exactly why businesses on the Kansas side hold a 913 number deliberately rather than settling for the code across the river.

The 913 code covers the Kansas counties that border Missouri — chiefly Johnson, Wyandotte, and Leavenworth, along with Miami, Linn, and Atchison. That footprint runs from the dense corporate suburbs south of the river, north across the Kansas River into the industrial and residential core of Kansas City, Kansas, and out to the historic river town of Leavenworth. Four places capture its range and explain why the prefix means the Kansas side of the metro.

Overland Park

The largest city in the 913 territory and the second-largest in Kansas, Overland Park is the metro's suburban business capital — a planned expanse of corporate campuses, office parks, and master-planned neighborhoods. Its consistently high rankings for quality of life and schools have made it a magnet for headquarters and professional firms, and a 913 number is a core part of doing business there.

Olathe

The Johnson County seat, Olathe pairs rapid residential growth with a major technology presence, most visibly the global navigation company headquartered there. Its blend of family neighborhoods and engineering employers has made it one of the fastest-growing cities in the state.

Kansas City, Kansas

North across the Kansas River, Kansas City, Kansas — often shortened to KCK — anchors Wyandotte County with a working riverfront, a major medical center, and a consolidated city-county government. It carries the older, industrial character of the Kansas side, distinct from the newer suburbs to the south.

Leavenworth

Upriver from the metro, Leavenworth is the oldest incorporated city in Kansas and a historic military town. It marks the northern reach of the 913 code, connecting the suburban core to the river communities beyond.

The entire 913 region observes Central Time (CT) — UTC−6 during Standard Time and UTC−5 during Daylight Saving Time, which runs from mid-March to early November. The code shares its clock with Chicago, Dallas, and Minneapolis, and both sides of the state-line metro keep identical time, so a 913 number and a number across the border in Missouri always run on the same schedule.

Sitting near the geographic center of the country, a Central Time number is well placed for national calling. Morning hours overlap the East Coast and afternoon hours overlap the West, so a single 913 line can comfortably reach customers coast to coast inside one business day. Cloud phone systems lean on that predictability, letting a company set hours, route calls, and schedule follow-ups around a stable Central-Time presence.

Unlike most codes serving a metro of its size, 913 still has no overlay — it remains a single code covering its territory, a sign that careful number management and the 1997 split kept its supply healthy. That makes the local dialing pattern unusually clean, and it leaves the surrounding codes to tell the rest of the regional story.

Across the state line, the 816 area code carries the Missouri side of the same metro, so the two codes together cover one market split by a border.

• 913 — the Kansas side of the Kansas City metro, including Overland Park, Olathe, and Kansas City, Kansas
• 816 — the Missouri side of the metro, including downtown Kansas City and the Northland
• 785 — the rest of northern and eastern Kansas, including Topeka and Lawrence, split from 913 in 1997
• 620 — southern Kansas, covering the state's rural southern tier below the metro

The state line makes the pattern easy to read: 913 numbers sit on the Kansas side, 816 numbers on the Missouri side, and 785 covers the Kansas cities beyond the suburbs. Metro companies frequently operate across the border, but the Kansas-side prefix is the one that signals Johnson County and the suburban business corridor specifically.

A 913 number connects a business to one of the strongest suburban economies in the Midwest. Johnson County pairs a deep bench of corporate headquarters with low operating costs, short commutes, and a highly educated workforce, and the Kansas side of the metro has become the region's preferred address for national companies. Three sectors stand out.

Corporate Headquarters

Overland Park hosts one of the metro's largest corporate campuses — the sprawling former Sprint world headquarters, now a mixed-use hub anchored by a major wireless carrier — alongside the long-established global engineering firm Black & Veatch, which has run water and power projects worldwide from the same city for more than a century. These headquarters handle high call volumes daily, and a recognizable local prefix keeps their outreach reading as legitimate to the customers they serve.

Technology & Navigation

Neighboring Olathe is home to the global headquarters of a leading GPS and navigation company, whose steadily expanding campus has made it one of the metro's marquee technology employers. Around it sits a growing cluster of engineering, software, and aviation-electronics firms that give the Kansas side a genuine high-tech identity.

Healthcare & Education

Kansas City, Kansas anchors the region's medical economy through a major academic medical center and teaching hospital, while Johnson County's community college and school districts rank among the largest employers in the suburbs. Together they support a broad workforce of clinicians, researchers, educators, and the small businesses that serve them.

Getting a Kansas-side number today is an online task, not a real-estate decision. Cloud phone providers hold local 913 inventory that activates in minutes and routes anywhere, so a business can sound rooted in Johnson County without a physical office there. Because 913 reads as the Kansas side of the metro, the number lands as authentically local from Overland Park to Leavenworth, even for a team working entirely remotely.

1. 1Choose a provider — pick a cloud phone service with 913 numbers and the features the team needs, such as routing rules, call recording, and CRM integration.
2. 2Pick a number — browse available 913 combinations and choose one that reads well on a storefront or website; it will display as (913) 555-0123, or +1 913-555-0123 internationally.
3. 3Activate and route — finish verification and go live. Calls ring on any device — desk phone, laptop app, or mobile — no matter where the team actually sits.

The line then works like any established local number: add extensions, set Central Time business hours, and keep the same digits permanently, even if the company relocates within the metro. Setting up a dedicated business phone number this way takes minutes, and existing 913 lines can usually be ported into a cloud platform without changing a digit — protecting whatever recognition the number has already earned on trucks, signs, and directories.

The Kansas City metro's defining quirk is its split personality: two states, two area codes, one market. 913 signals the Kansas side — Johnson County's corporate suburbs and the Wyandotte County riverfront — while 816 signals the Missouri side, including downtown Kansas City and the neighborhoods around it. Neither is 'better'; they simply speak to different audiences within the same region.

• 913 — the Kansas side, associated with Overland Park, Olathe, and the Johnson County business corridor
• 816 — the Missouri side, associated with downtown Kansas City, the Plaza, and the Northland
• Both share Central Time and one local calling market, and calls between them are routine everyday business

For a company deciding between them, the choice comes down to where its customers are. A firm serving Overland Park offices, Olathe families, or Kansas-side contractors is far better matched by a 913 number that neighbors instantly read as their own, while a business rooted in the Missouri core leans toward 816.

Many multi-market operations simply hold one of each in the same account, so both sides of the state line see a familiar prefix while one team answers every call.

The same 'local Kansas City' quality that makes 913 useful to businesses also makes it a convenient disguise for fraud, and an affluent, densely populated suburban market is a rich target. Caller-ID spoofing lets someone anywhere in the world display a 913 prefix, so a resident sees what looks like a nearby business, bank, or county office calling.

The prefix itself proves nothing — genuine and spoofed calls look identical on screen, and scammers know a familiar local code is more likely to be answered.

• Fake bank or payment alerts — voicemails or texts about a 'suspicious transaction,' pushing you to call back or tap a link
• Prize and refund lures — claims you have won something or are owed a refund, requesting card details to 'process' it
• Utility and delivery threats — messages that your power will be cut or a package held unless you pay a small fee immediately

The reliable defense is to hang up and call back through a number found independently — on a bill, an official site, or a saved contact. No genuine bank, agency, or utility demands gift cards or wire transfers over the phone. Federal law makes it illegal to transmit misleading caller-ID information with intent to defraud, but such calls still slip through, so treat any pressure to act immediately as a warning sign in itself.
