History of telephone area code 304
The telephone area code 304 was officially introduced in 1947 when AT&T and Bell System created the North American Numbering Plan.
At the time, each state generally received a single area code.
Because West Virginia’s population remained relatively stable compared to larger states, telephone area code 304 continued serving the entire state for over 70 years without requiring a geographic split.
This longevity makes it one of America’s longest-running original area codes.
Why Was a New Area Code Added?
As mobile phones, internet services, fax machines, and business phone systems expanded, the number of available telephone numbers within telephone area code 304 gradually declined.
Instead of dividing West Virginia into multiple geographic regions, telecommunications authorities introduced an overlay area code.
This allowed existing customers to keep their current phone numbers while making additional numbers available for future growth.
The Introduction of Area Code 681
To ensure enough phone numbers for the future, area code 681 was introduced as an overlay for the same geographic region served by telephone area code 304.
Today:
- Existing numbers remain unchanged.
- New numbers may receive either 304 or 681.
- Both area codes serve the entire state.
- Ten-digit dialing is required for local calls.
This approach avoided forcing millions of residents and businesses to change their existing phone numbers.
