479 Area Code: Your Guide to Northwest Arkansas

Quick answer: Area code 479 serves northwest and western Arkansas, a standalone area code created in 2002 from a split of the older 501 region. It covers Fort Smith, Fayetteville, Springdale, Rogers, and Bentonville, across Benton, Washington, Sebastian, Crawford, and surrounding counties. The entire region sits in the Central Time Zone, and ten-digit dialing reliably connects every call.

What is the 479 area code?

The 479 area code is the telephone prefix for the northwestern and western corner of Arkansas — a region that pairs the historic river city of Fort Smith with one of the fastest-growing metropolitan areas in the United States, the Fayetteville–Springdale–Rogers corridor. It is a standalone, single-area code, so every number across the region shares the same 479 prefix.

Like the 478 area code, which was carved out of 912 to serve central Georgia, 479 was created the traditional way — through a geographic split rather than an overlay. When Arkansas's original numbering region could no longer keep up with demand, the western third of the state was given its own dedicated code.

For its size, 479 is one of the most economically significant area codes in the country. It is rare for a single, non-metropolitan area code to contain the global headquarters of three Fortune 500 companies, yet that is exactly what the northwest Arkansas boom has produced — giving the 479 prefix a recognition among business callers that reaches far beyond the state line.

What cities and counties does 479 cover?

The 479 area code covers the western edge of Arkansas, from the Missouri border in the north down through the Arkansas River Valley. The region blends a booming corporate metro in the Ozark highlands with the older industrial and historic communities along the river.

Major cities in the 479 area code:

• Fort Smith — Arkansas's second-largest city, a historic Old West frontier town on the Oklahoma border, now a regional manufacturing, healthcare, and logistics hub
• Fayetteville — Home to the University of Arkansas and the Razorbacks, anchoring the region's education, research, and cultural life
• Springdale — The headquarters city of Tyson Foods and the heart of the region's food-processing and poultry industry
• Rogers — A fast-growing retail and commercial center near the original Walmart store and a dense cluster of corporate offices
• Bentonville — The global headquarters of Walmart, the world's largest company by revenue, and home to the Crystal Bridges Museum of American Art
• Bella Vista and Bentonville suburbs — Rapidly expanding residential communities that have made northwest Arkansas one of the country's fastest-growing regions
• Van Buren, Siloam Springs, Russellville, and Harrison — River Valley and Ozark communities that round out the 479 footprint

Counties within the 479 service territory:

Northwest Arkansas has been one of the fastest-growing regions in the United States for two decades, and its character shows in the 479 footprint. The Bentonville–Rogers–Springdale–Fayetteville corridor has filled in almost continuously along Interstate 49, blending corporate campuses, the Crystal Bridges Museum of American Art, and a celebrated network of mountain-biking trails that has drawn national attention.

To the south and west, Fort Smith and the Arkansas River Valley offer an older, more industrial counterpoint — frontier history, manufacturing, and river commerce — all sharing the same 479 prefix.

The entire 479 coverage area observes Central Time (UTC−6 in winter, UTC−5 during DST). When scheduling calls between northwest Arkansas and Eastern Time cities such as Atlanta or New York, remember that the 479 region runs one hour behind.

The story behind the 479 area code

Arkansas began the telephone era with a single area code. In 1947, when AT&T established the North American Numbering Plan, the entire state was assigned area code 501. For half a century, one code covered everything from Little Rock to the Ozarks to the Delta.

By the 1990s, the spread of fax machines, pagers, and second residential lines made a single statewide code unworkable. In 1997, area code 870 was split off to serve the northern, eastern, and southern portions of the state, leaving 501 to cover central and northwestern Arkansas.

That relief did not last long. The explosive growth of northwest Arkansas — driven by the expansion of Walmart, Tyson Foods, and J.B. Hunt, and the thousands of supplier offices that followed them — combined with the mobile-phone boom to exhaust 501's remaining numbers within a few years.

In 2002, area code 479 was split from 501 to serve northwest and western Arkansas, including Fort Smith, Fayetteville, and Bentonville. The 501 code was retained for the Little Rock metro and central Arkansas. Permissive dialing eased the change before the new code became mandatory.

The Arkansas Public Service Commission regulates telephone numbering in the state and works with the North American Numbering Plan Administration on relief planning. By choosing a clean geographic split in 2002, regulators gave the booming northwest its own identity in a single, memorable code.

Key milestones:

• 1947 — Arkansas assigned a single area code, 501, for the entire state
• 1997 — 870 split off to serve northern, eastern, and southern Arkansas
• 2002 — 479 split from 501 to serve northwest and western Arkansas
• Early 2020s — Ten-digit dialing adopted following the rollout of the 988 Suicide & Crisis Lifeline

How to dial a 479 phone number

Because 479 is a single standalone area code, northwest Arkansas historically allowed seven-digit local dialing. Following the nationwide introduction of the 988 Suicide & Crisis Lifeline, regions that used 988 as a local prefix moved to ten-digit dialing, and dialing all ten digits is now the dependable standard across the 479 region.

To avoid failed calls, save every northwest Arkansas contact with the full 479 area code. Any number stored as seven digits should be updated to the complete ten-digit format so it connects dependably from any phone or carrier.

Time zone tip: Northwest Arkansas observes Central Time — one hour behind Eastern Time (Atlanta, New York), one hour ahead of Mountain Time, and two hours ahead of Pacific Time. Dallas, Chicago, and the rest of Arkansas share the 479 region's Central Time Zone.

Should you get a 479 number for your business?

Few regions of comparable size carry the corporate weight of northwest Arkansas. Three Fortune 500 companies are headquartered within the 479 area code, surrounded by one of the densest supplier and logistics ecosystems in the country — which makes a recognized local number a genuine business asset here. A 479 prefix signals that your business is part of this community, an advantage that a generic toll-free or out-of-state number simply cannot match when you are pitching a Bentonville buyer or a Springdale supplier.

Reasons to choose a 479 area code number:

• Retail and supplier ecosystem — Walmart's Bentonville headquarters draws thousands of supplier offices to the region, often called "Vendorville," creating constant demand for local vendor and partner relationships
• Food and agribusiness — Tyson Foods, headquartered in Springdale, anchors a vast poultry and food-processing sector that supports suppliers, equipment vendors, and service providers across the region
• Transportation and logistics — J.B. Hunt, based in nearby Lowell, makes the region a national trucking and supply-chain hub with dense demand for logistics and B2B services
• Higher education and talent — The University of Arkansas in Fayetteville fuels a steady pipeline of graduates, research partnerships, and demand for housing, technology, and professional services
• Virtual reach — Just as businesses target Pittsburgh's market through a 472 area code number without an office there, a virtual 479 number routes calls to any device and connects you with northwest Arkansas from any location

479 area code scam calls and how to avoid them

Because 479 numbers are instantly recognized as local across northwest Arkansas, fraudsters spoof them to appear trustworthy. Neighbor spoofing — displaying a 479 number with a prefix matching your own town — is especially effective in a single-area-code region where the prefix is so familiar.

Common 479 scam types to watch for:

• IRS and tax fraud — Callers threatening immediate arrest over unpaid taxes, a high-pressure tactic aimed at residents and small-business owners
• Social Security suspension fraud — Automated messages claiming your Social Security number has been suspended, frequently targeting older residents
• Utility shutoff threats — Callers posing as SWEPCO or Ozarks Electric representatives demanding same-day payment to prevent service disconnection
• Gift card and retail impersonation — Scammers posing as Walmart, Amazon, or other retailers claiming a problem with your order and pressuring you to pay or "verify" with gift cards
• Job offer and recruitment scams — Fake recruiters exploiting the region's booming job market with bogus offers that ask for personal information or upfront fees

How to protect yourself:

• Let unknown 479 calls go to voicemail and verify the caller independently before returning the call
• No government agency, utility, or legitimate employer will demand payment by gift card, wire transfer, or cryptocurrency during an unsolicited call
• Confirm any company through the contact details listed on its official website
• Report suspected 479 scam calls to the FTC at reportfraud.ftc.gov
