479 Area Code: Northwest Arkansas & Fort Smith

The 479 area code is the telephone code of northwest Arkansas — a region anchored by two distinct hubs, the booming Northwest Arkansas metro of Fayetteville, Bentonville, Rogers and Springdale, and Fort Smith and the Arkansas River Valley about an hour to the south.

It rings across thirteen counties tucked into the Ozark and Boston Mountains foothills, reaching from Siloam Springs near the Oklahoma border east through Fayetteville's university corridor and south to Fort Smith's historic riverfront. A phone number that begins with 479 signals this specific corner of the state: home to Walmart's headquarters, the Ozarks' fastest-growing suburbs, and one of Arkansas's oldest frontier cities.

Because 479 covers a region that has changed enormously since the code was created, it turns up in two very different searches: people who just received a 479 number and want to know where it comes from, and people asking whether an unfamiliar 479 call is safe to answer.

This guide covers both — the cities and communities that make up the 479 region, how it split off from Arkansas's 501 code in 2002, the dialing detail that sets it apart from most modern area codes, what to watch for with spoofed calls, and how to activate a 479 virtual number for a business in minutes.

The 479 area code is a telephone area code serving thirteen counties in northwest Arkansas, anchored by the Fayetteville–Bentonville–Rogers–Springdale metro and reaching south to Fort Smith. It was put into service on January 19, 2002, split off from the 501 area code as rapid population and business growth in the region pushed the older, statewide code toward exhaustion.

Unlike several fast-growing metros elsewhere in the country, 479 has never been overlaid with a second code — it remains a single area code for the entire region nearly a quarter-century later.

Many companies opening a location across Northwest Arkansas or the River Valley request a dedicated VoIP phone number on 479 specifically so the line reads as local from the first ring, without needing a physical office in the state.

Dialing Format and Time Zone

• Dialing format: (479) 555-0142
• International: +1 479-555-0142
• Time zone: Central Time (CT) — UTC−6 during Standard Time, UTC−5 during Daylight Saving Time
• 479 has never been overlaid, so seven-digit local dialing generally remains available within the region — one of a shrinking number of U.S. area codes where this is still true

Geographically, 479 covers the northwestern corner of Arkansas, split between two economic centers that share the same code but function almost as separate metros. To the north, the Northwest Arkansas region climbs into the Ozark foothills; to the south, Fort Smith and the River Valley sit along the Arkansas River near the Oklahoma border. Together they form one of the fastest-growing parts of the state.

Major Cities and Communities

• Fayetteville — the region's largest city, home to the University of Arkansas and a fast-growing downtown and arts scene
• Bentonville — headquarters of Walmart and the Crystal Bridges Museum of American Art, transformed over two decades from a small county seat into a national business hub
• Rogers & Springdale — the retail, logistics and food-processing cities anchoring the northern half of the metro, home to J.B. Hunt Transport and major Tyson Foods operations
• Siloam Springs — the westernmost 479 city, sitting directly on the Oklahoma border
• Fort Smith — the historic second city of Arkansas on the Arkansas River, anchored by Chaffee Crossing and a diversified manufacturing base
• Van Buren & the River Valley — Fort Smith's sister city across the river, along with Alma, Ozark and the smaller River Valley communities

Beyond the 479 region, the 501 area code covers central Arkansas and Little Rock to the southeast, the 870 area code (with its 327 overlay) reaches the rest of the state to the south and east, and across state lines Oklahoma's 918 and 479's Missouri neighbor 417 pick up the surrounding Ozark communities.

The entire 479 region observes Central Time (CT) — UTC−6 during Standard Time in the fall and winter, and UTC−5 during Daylight Saving Time from mid-March through early November — the same clock as Little Rock, Memphis, Dallas and Chicago, one hour behind New York and two ahead of the West Coast.

For a business choosing a 479 line, that time zone puts Northwest Arkansas and Fort Smith on the same working schedule as most of the country's population centers, which is one reason a wave of corporate suppliers and logistics firms have clustered around Bentonville over the past two decades: a Central-Time office reaches both coasts within a normal business day.

A team working 8 a.m. to 5 p.m. Central is reachable from 9 a.m. on the East Coast through mid-afternoon on the West Coast.

479's story is one of a single geographic split, not an overlay. When Arkansas was first assigned telephone service in 1947, one area code — 501 — covered the entire state. As the population grew, that single code was split in stages: 870 was carved off in 1997 to cover the rest of the state outside the central region, and 479 followed in 2002, taking Northwest Arkansas and the Fort Smith River Valley out of the 501 territory.

• 501 — Arkansas's original 1947 code, now narrowed to Little Rock and central Arkansas
• 870 — split off in 1997 to cover the rest of the state outside central Arkansas, later joined by the 327 overlay in 2024
• 479 — split off from 501 on January 19, 2002, taking the thirteen counties of northwest Arkansas and Fort Smith

That 2002 split was driven by rapid growth around Bentonville, Fayetteville and the wider Northwest Arkansas metro straining the old 501 territory's supply of numbers, and regulators chose to divide the region geographically rather than add an overlay.

The result is that 479 has kept a single, unambiguous footprint for nearly a quarter century — no second code has ever been layered on top of it, unlike neighboring 870, which added the 327 overlay in 2024 as its own numbers ran low. A business or resident with a 479 number today can be confident it will still mean the same region for years to come.

A 479 number connects a business to one of the fastest-growing regional economies in the country — in January 2026, the Milken Institute ranked Northwest Arkansas the No. 1 best-performing large metro in the nation, citing strong job growth and wage gains. Where much of the rural South reads as agriculture alone, the 479 region reads as global corporate headquarters, logistics and food processing, layered on top of a historic river-valley manufacturing base to the south.

A Retail and Logistics Powerhouse

Northwest Arkansas anchors a concentration of corporate headquarters unusual for a metro its size: Walmart in Bentonville, Tyson Foods in Springdale, and J.B. Hunt Transport Services in nearby Lowell, together with a dense supply-chain ecosystem of vendor offices that grew up around them over the past two decades. The University of Arkansas in Fayetteville feeds graduates directly into that workforce, and business services, transportation and logistics, and distribution and e-commerce now rank among the region's top employment sectors.

Fort Smith's Manufacturing Legacy

South of the metro, Fort Smith carries a longer industrial history as Arkansas's historic second city, built on furniture, machinery and food manufacturing along the Arkansas River. Chaffee Crossing, the redeveloped former Army post on the city's edge, now hosts a mix of aerospace, defense and light manufacturing tenants, while Fort Smith's downtown and national historic site continue to anchor a smaller but steady tourism trade tied to the region's frontier-era past.

Modern cloud phone providers let a business activate a 479 number in minutes — no Fayetteville or Fort Smith office, no hardware, and no long-term contract. Search available 479 numbers, complete a short verification, and route the line to any device anywhere in the world. Because the code is instantly recognizable across Northwest Arkansas and the River Valley, the number reads as authentically local across the whole region, even for a team working remotely from elsewhere.

A 479 number suits any business already targeting the region: retail and logistics vendors building a presence near Bentonville and Rogers, suppliers and consultancies serving the Walmart and Tyson ecosystem, manufacturers or contractors around Fort Smith's Chaffee Crossing, and remote teams targeting Northwest Arkansas from out of state.

A business that already has a 501 or 870 Arkansas number can also add a 479 line as a second number without losing the local read. MeraTalk provides 479 numbers as part of its cloud telephony platform — lines activate in minutes, route to any device, and pair with voicemail, call recording, an auto-attendant and CRM integration from one dashboard.

479 is a legitimate, long-established Arkansas code, but like any area code its numbers can be spoofed. Caller-ID spoofing lets a fraudster make any number — including a 479 prefix — appear on a screen, so a resident sees what looks like a nearby Fayetteville, Bentonville or Fort Smith business, bank or agency calling.

The prefix itself proves nothing: a genuine 479 call and a spoofed one look identical, and fast-growing Northwest Arkansas in particular has drawn its share of consumer complaints about unwanted sales and scam calls tied to its rapid population growth.

• Fake bank or payment alerts — a voicemail or text 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
• Fake job or apartment-rental offers — common in a fast-growing region where newcomers are actively searching for housing and work

The reliable defense is to hang up and call back through a number you find independently — on a bill, an official website or a saved contact. No genuine bank, utility or government agency demands gift cards or wire transfers over the phone, and a local-looking 479 caller ID is never proof of who is really on the line. Arkansas residents who encounter a suspicious call can review current guidance and file a report through the Arkansas Attorney General's office. For more, see Arkansas Attorney General's office.
