What Is the 304 Area Code? West Virginia's Complete Guide

Introduction

The 304 area code is West Virginia's primary telephone prefix, serving every county of the Mountain State from the Ohio River valley to the Appalachian highlands. Knowing what the 304 area code covers matters — whether you received a call from an unfamiliar number, you're expanding a business into West Virginia, or you simply want a local line in the state. This guide covers the 304's exact location, full history, major cities, dialing rules, scam awareness, and how to get a 304 phone number of your own. Read on for everything you need, from the code's 1947 origins to activating a virtual line today.

Key Takeaways

• The 304 area code has served all of West Virginia since 1947 — one of North America's original telephone prefixes.
• West Virginia added overlay code 681 in September 2018 when 304 numbers ran low; both codes cover the exact same territory.
• Charleston, Huntington, Morgantown, Parkersburg, and Wheeling are the major cities in the 304 footprint.
• The 304 region runs on Eastern Time — the same zone as New York City and Washington, D.C.
• You can get a virtual 304 phone number from anywhere, without living or working in West Virginia.

What Is the 304 Area Code?

The 304 area code is a geographic telephone prefix assigned to the entire state of West Virginia. It was created in 1947 as one of the original 86 area codes established under the North American Numbering Plan (NANP). For more than 70 years, 304 was the sole area code in the state.

As demand for new phone numbers grew, regulators introduced area code 681 as an overlay on September 7, 2018. Both codes now serve the same territory — all 55 counties of West Virginia. New subscribers may receive either a 304 or 681 prefix, and every existing 304 number stayed intact when 681 launched.

Where the 304 Area Code Reaches

The 304 area code covers all 55 counties of West Virginia — the only US state with a single original area code still in active use statewide. West Virginia spans roughly 24,230 square miles of Appalachian terrain, bordered by Virginia, Kentucky, Ohio, Pennsylvania, and Maryland.

Coverage stretches from the Eastern Panhandle — less than an hour from Washington, D.C. — to the Western Panhandle along the Ohio River. Every major city, county seat, and rural community in the state falls inside the 304 footprint.

Cities and Communities in the 304 Region

• Charleston: The state capital and largest city in the 304 footprint. Charleston anchors the Kanawha Valley with government offices, medical centers, and a growing tech and healthcare economy. It sits at the junction of the Kanawha and Elk rivers.
• Huntington: West Virginia's second-largest city, home to Marshall University and one of the region's leading medical complexes. Huntington has reinvented itself with a growing healthcare corridor and vibrant arts district along the Ohio River.
• Morgantown: Home to West Virginia University, Morgantown drives a young, education-focused economy. The city consistently ranks among West Virginia's most livable communities, with strong research, biotech, and small-business activity.
• Parkersburg: An Ohio River industrial hub with a long manufacturing history in chemicals, plastics, and retail. Parkersburg sits at the West Virginia–Ohio border and serves as a key commercial gateway for the region.
• Wheeling: The northernmost major city in the 304 footprint, near the Pennsylvania and Ohio borders. Wheeling has a rich industrial heritage and a revitalized downtown built around healthcare, hospitality, and small business.
• Beckley, Clarksburg, Martinsburg, Fairmont: Additional cities spread across the state's coal country, Northern Panhandle, Eastern Panhandle, and north-central corridor — each with its own economic and cultural identity within the 304 region.

From 1947 to the 681 Overlay — The Full 304 Timeline

The 304 area code is one of the most enduring telephone prefixes in North America. AT&T and the Bell System assigned it to West Virginia in 1947 when they mapped the continent into 86 original numbering plan areas. From that first assignment, 304 covered the entire state — and held that position alone for over 70 years.

The 304 Area Code Timeline

• 1947 — Created: Area code 304 is assigned to all of West Virginia as one of the original 86 NANP area codes. It is the state's sole prefix from day one.
• 2015 — Relief Planning Begins: The West Virginia Public Service Commission begins planning for a second area code as the 304 number pool approaches exhaustion.
• September 7, 2018 — Overlay Activated: Area code 681 launches as an overlay across the same territory as 304. All existing 304 numbers remain unchanged.
• 2019 — 10-Digit Dialing Mandatory: All local calls within West Virginia require 10-digit dialing to accommodate both 304 and 681 on the same network.

Why West Virginia Kept One Code for So Long

West Virginia's relatively stable population — currently around 1.77 million — meant the 304 number pool lasted far longer than in faster-growing states. The state's largely rural character also reduced demand: fewer businesses, fewer residents, and fewer new lines kept 304 sufficient well into the 2010s. When exhaustion finally approached, the overlay solution preserved every existing 304 number without disruption.

Eastern Time and 10-Digit Dialing in the 304

The entire 304 region runs on Eastern Time (ET):

• Eastern Standard Time (EST): UTC−5, from the first Sunday in November to the second Sunday in March.
• Eastern Daylight Time (EDT): UTC−4, from the second Sunday in March to the first Sunday in November.

This puts West Virginia in sync with New York, Philadelphia, and Washington, D.C. Callers from Central, Mountain, or Pacific time zones should keep the Eastern offset in mind when scheduling calls to West Virginia contacts.

How to Dial a 304 Number

• Within West Virginia: Always dial all 10 digits — 304-XXX-XXXX. Seven-digit local dialing has not been valid since 2019.
• From anywhere else in the US or Canada: Dial the full 10-digit number directly — no special prefix needed.
• From outside North America: Dial +1-304-XXX-XXXX (or 00-1-304-XXX-XXXX on most international landlines).

Why a 304 Number Works for Your Business

A local 304 area code tells West Virginia customers that your business belongs to their community. Research consistently shows that people are more likely to answer calls from familiar local area codes than from toll-free or out-of-state numbers. That difference in answer rate can directly affect your sales, bookings, and revenue.

A virtual 304 phone number also gives remote businesses a West Virginia presence without the cost of a physical office. You can route calls to any device, set business hours, separate personal and work lines, and track call activity — all from one virtual line.

Business Benefits of a Virtual 304 Line

• Higher answer rates from local West Virginia customers who recognize the area code
• Separate business and personal calls on a single smartphone
• Call forwarding to any location — office, mobile, home, or overseas
• Professional voicemail and hold features that scale with your team's growth

Scam Calls from 304 Numbers — What to Know

Not every call displaying a 304 number on your caller ID is legitimate. Scammers use a technique called neighbor spoofing — displaying a local 304 number to make their call appear to come from West Virginia. The actual call may originate from another country or a different US state entirely.

Check Unknown 304 Numbers Before Calling Back

If you receive an unexpected call from an unfamiliar 304 number, search it online before returning the call. Legitimate West Virginia businesses and individuals do not typically send robocalls or leave generic automated messages asking you to call back immediately.

Watch for Government and Prize Impersonators

Common scam patterns in the 304 region include IRS impersonators, Social Security Administration fraud calls, and fake prize notifications. No real government agency demands immediate payment by phone, and no legitimate prize requires an upfront fee to collect winnings.

Protect Your Personal Information

Hang up immediately if an unknown caller asks for your Social Security number, bank account details, or passwords — regardless of how official they sound. You can report suspected scam calls to the FTC fraud report service.
