304 Area Code: One Number for All of West Virginia

The 304 area code covers the entire state of West Virginia — every city, town, and hollow, from the capital at Charleston to Huntington, Morgantown, Wheeling, and the Eastern Panhandle. It is one of the original 1947 area codes, and for more than sixty years it was the only code the Mountain State ever needed.

This guide explains where 304 reaches, why a single code served West Virginia for so long, how the 681 overlay changed dialing, how to call correctly, how to avoid 304 scams, and how to get a 304 number for your business from anywhere.

Where is the 304 area code?

The 304 area code serves all of West Virginia — roughly 24,000 square miles spanning all 55 counties. No part of the state uses a different geographic code. From Harpers Ferry in the Eastern Panhandle to Huntington on the Ohio River, every landline, cell, and VoIP number is rooted in 304.

Cities and communities inside the 304 footprint include:

Neighboring states use their own codes — Virginia uses 540 and 276, Ohio uses 740 and 614, Pennsylvania uses 412 and 724, and Kentucky uses 606.

Why one code covered West Virginia for 60 years

When the North American Numbering Plan launched in 1947, West Virginia was assigned 304 from day one — and for decades that single code was plenty. The state's population has hovered around 1.8 million and has actually declined in recent years, so the 304 number pool was never pushed as hard as fast-growing states like California or Texas.

This puts West Virginia in rare company. Only a handful of states have ever run on a single area code; Maine, for example, has used its 207 area code statewide since 1947 and has never needed a second. West Virginia held out almost as long — but eventually even modest growth in cell phones and second lines exhausted the supply.

How the 681 overlay changed things

By the late 2000s, the 304 number pool was finally running low. Rather than split the state into two regions — which would have forced half of West Virginia to change numbers — regulators added the 681 overlay in 2009. The 681 code covers the exact same territory as 304: all of West Virginia.

The trade-off of an overlay is ten-digit dialing. Before 2009, West Virginians could dial just seven digits for a local call. Since the overlay, every call requires the full area code plus number, and new lines may be issued as either 304 or 681 depending on availability. No existing 304 number had to change.

How to dial a 304 number

Because West Virginia now has an overlay, ten-digit dialing is mandatory — there is no seven-digit shortcut anywhere in the state.

The 304 area code sits in the Eastern Time Zone (ET) — EST (UTC−5) in winter and EDT (UTC−4) in summer, the same clock as Washington, D.C. and New York. At noon in Charleston it is 11 AM in Chicago, 10 AM in Denver, and 9 AM in Los Angeles.

What the 304 region runs on

West Virginia's economy is tied to its mountains and rivers. The state was built on coal, natural gas, and chemicals, and energy still anchors the southern coalfields and the Charleston chemical corridor. But the 304 footprint is broader than that today:

• Education and healthcare — West Virginia University in Morgantown and Marshall University in Huntington are major regional employers, anchoring growing biomedical and research sectors.
• Energy — coal, plus a booming Marcellus and Utica shale gas industry across the north.
• Government and commuting — the Eastern Panhandle (Martinsburg, Charles Town) has become a fast-growing bedroom community for the Washington, D.C. metro.
• Tourism — whitewater rafting on the New and Gauley rivers, skiing, and the New River Gorge National Park draw visitors statewide.

A 304 number signals you are part of this statewide community — useful for healthcare networks, energy services, contractors, and any business serving customers across the Mountain State. You can get a local 304 number from My Country Mobile to reach them.

304 area code scams

A familiar statewide code is exactly what scammers want. Fraudsters spoof 304 numbers — faking a West Virginia prefix, sometimes matching the first digits of your own number — so a call looks local and trustworthy. A 304 on your screen does not prove the caller is really in the state.

A few habits keep you safe:

• Let unknown 304 calls go to voicemail; legitimate callers leave a message.
• Never share one-time codes, card numbers, or login details with an inbound caller.
• Be skeptical of "utility shutoff," "Social Security suspended," or "your account is compromised" calls that pressure you to act fast.
• Use carrier spam filtering. The FCC's STIR/SHAKEN call authentication framework is why many phones now label these calls as "Spam Risk."

Getting a 304 number for your business

If you serve West Virginia — energy, healthcare, trades, tourism, or professional services — a 304 number puts a Mountain State address on your caller ID without an in-state lease. It signals you are plugged into the local market and lifts answer rates with West Virginia contacts.

You do not need a Charleston office to claim one. A cloud phone provider can assign you a 304 number that rings on your existing devices and routes calls anywhere in the world. With a provider like My Country Mobile, you can pick a 304 line, configure routing, an auto-attendant, and voicemail, and be live in minutes — whether you are a one-person shop or a national brand opening a West Virginia presence.
