304 Area Code: 7 Essential West Virginia Call Facts

The 304 area code is the primary telephone area code serving the entire state of West Virginia. Established on January 1, 1947, it was one of the original 86 area codes created when AT&T and the Bell System introduced the North American Numbering Plan (NANP). Today, 304 covers all 55 counties of West Virginia — from the panhandle in the north to the coalfields in the south — and operates alongside the 681 overlay code, which was added in 2009. If you’ve received a call from a number starting with 304, it’s coming from somewhere in the Mountain State.

I’ve spent time researching area code data across hundreds of U.S. regions, and what strikes me about 304 is how much history it carries — and how many searchers still don’t fully understand what the overlay means, whether a 304 call is legitimate, or how dialing works in 2025. This article covers all of that.

The History Behind the 304 Area Code

When the NANP was introduced in 1947, West Virginia was assigned area code 304 as a single-state code. The middle digit “0” in 304 wasn’t random — it was a deliberate encoding. Under the original NANP rules used before 1953, a middle digit of “0” indicated that the area code covered an entire state, while a middle digit of “1” meant it covered only a portion. So 304’s structure literally told you it was a full-state code.

For over six decades, West Virginia ran on just that one area code. That’s a notable feat, given that larger states like California and New York had fractured into dozens of codes by the early 2000s.

By 2007, though, the growth of mobile phones and fax machines was eating through available numbers fast. News reports at the time warned that West Virginia would exhaust its 304 number supply within a few years.

The 2008 Split Debate — and Why It Didn’t Happen

In January 2008, the West Virginia Public Service Commission voted to split the 304 numbering area. The original plan would have given Charleston, Parkersburg, Huntington, Bluefield, and Beckley the 304 code, while the northern and eastern parts of the state — including Wheeling and Martinsburg — would move to a new code.

That plan was shelved within weeks.

Telecommunications providers, rural communities, and government officials all pushed back hard. Changing numbers would mean reprogramming cell phones, updating business cards, and reprinting marketing materials — a genuine burden for rural West Virginians who couldn’t easily absorb that disruption. Governor Joe Manchin came out in support of an overlay instead.

On February 13, 2008, all three commissioners reversed course and unanimously approved an overlay plan — the first time an entire U.S. state had chosen an overlay to address number exhaustion rather than splitting. Area code 681 launched as that overlay on March 1, 2009.

What the 681 Overlay Means (And Why It Matters)

An overlay is different from a split. In a split, one geographic area keeps the old code, and another gets a new one. In an overlay, both codes cover the exact same geographic territory simultaneously.

That means 681 is not a separate region — it’s another layer on top of 304, covering the same 55 counties and the same cities. A Morgantown resident might have a 304 number while their neighbor has a 681 number. Both are valid West Virginia numbers.

The practical consequence: all local calls in West Virginia require 10-digit dialing. You can’t just dial seven digits anymore. Every call — even to someone across the street — needs the full area code included.

Cities and Counties Covered by the 304 Area Code

The 304 area code spans the full geographic footprint of West Virginia — all 55 counties, more than 230 cities, and over 360 ZIP codes. The state sits in the Eastern Time Zone (UTC -5 in winter, UTC -4 during Daylight Saving Time).

Major cities under the 304 area code include:

• Charleston (state capital, Kanawha County)
• Huntington (Cabell County)
• Morgantown (Monongalia County — home of WVU)
• Parkersburg (Wood County)
• Wheeling (Ohio County)
• Beckley (Raleigh County)
• Fairmont (Marion County)
• Clarksburg (Harrison County)
• Martinsburg (Berkeley County)
• Weirton (Hancock County)

Charleston is the most populous city in the state and the center of state government, healthcare, and commerce. Morgantown has grown substantially thanks to West Virginia University, which brings research activity and a younger demographic into the region. Huntington, meanwhile, is a major healthcare hub anchored by the Marshall University medical program and Mountain Health Network.

Who’s Calling from 304? Understanding Scam Risks

One of the top reasons people search “304 area code” is because they received an unknown call and want to know if it’s legitimate.

Here’s what you should know: 304 is not a high-risk area code in itself. It’s a genuine, geographic code serving real people and businesses in West Virginia. However — and this is critical — scammers routinely spoof area codes using VoIP technology to make their calls appear local or regional. A 304 number on your caller ID does not guarantee the call is actually originating from West Virginia.

Common scam patterns that use spoofed 304 numbers include:

• IRS or Social Security impersonation calls
• Medicare and insurance fraud calls
• Fake debt collection
• “Neighbor spoofing” (using a local-looking number to increase answer rates)

If you receive a suspicious 304 call, do not share personal or financial information. You can report unwanted calls to the FTC at reportfraud.ftc.gov or use apps like Hiya, Truecaller, or RoboKiller to identify or block suspicious callers.

Legitimate 304 callers include West Virginia state agencies, healthcare systems like WVU Medicine and Charleston Area Medical Center (CAMC), businesses operating in the state, and university offices.

How to Dial a 304 Number Correctly

Since the 681 overlay was introduced, 10-digit dialing is mandatory for all calls within West Virginia.

Here’s how to dial depending on where you’re calling from:

Seven-digit dialing no longer works for any West Virginia calls. This became mandatory on February 28, 2009, when the 681 overlay went live. If you’re setting up a phone system for a West Virginia business, make sure all your routing templates use full 10-digit formats.

Getting a 304 Area Code Number for Your Business

If you run a business that serves West Virginia customers, having a local 304 number builds immediate credibility. Studies consistently show that local numbers get significantly higher answer rates than toll-free or out-of-state numbers — customers are simply more likely to pick up.

You can get a 304 number through:

• Traditional landline carriers like Frontier (which manages a large share of West Virginia’s local prefixes)
• Wireless carriers, including Verizon, AT&T, and T-Mobile
• VoIP providers like Google Voice, RingCentral, Nextiva, or Vonage, which typically let you select a local area code during setup

VoIP is the most flexible option for remote businesses or those operating in multiple states. You can have a 304 number ring to any device, anywhere in the world. Pricing typically starts at $10–$30/month for a basic VoIP line with a local number.

Some providers also offer AI-powered virtual receptionist features bundled with local numbers, which can be particularly useful for small businesses that can’t always answer calls in real time.

West Virginia’s Economy Under the 304 Area Code

The 304 area code covers a region with a historically resource-driven economy. Coal mining, natural gas, and timber have anchored West Virginia’s economic identity for over a century — and while those industries have contracted, they remain significant.

Kanawha County alone generated a real GDP of approximately $11.44 billion in 2024, contributing meaningfully to West Virginia’s total state output of over $106 billion that year.

Key economic sectors in the 304 region include:

Energy and natural resources: American Consolidated Natural Resources, Arch Resources, Consol Energy, and Alpha Metallurgical Resources are among the major players still operating in the state.

Healthcare: WVU Medicine, Charleston Area Medical Center (CAMC), Mountain Health Network, and Mon Health System are among the largest employers in the state.

Manufacturing and aerospace: Toyota Motor Manufacturing West Virginia operates in Buffalo, WV. Northrop Grumman and Constellium also have significant presences in the region.

Tourism has grown steadily, particularly around the New River Gorge National Park — designated a National Park in 2020 — which draws whitewater rafters, rock climbers, and hikers from across the country.

Final Thoughts

The 304 area code is one of the oldest in the country, with a history that mirrors West Virginia’s own — resilient, community-driven, and resistant to being split up. Whether you’re trying to identify a call, get a local business number, or simply understand how West Virginia’s phone geography works, 304 is the number that defines the Mountain State.

If you’ve received a call from 304 and want to look it up, use a reverse phone lookup service like Whitepages or BeenVerified. And if you’re a business looking to establish a local presence in West Virginia, picking up a 304 VoIP number through any major provider is a straightforward and affordable place to start.
