History of Area Code 904

These changes helped make more telephone numbers available in different parts of Florida. The 904 area code continues to serve Jacksonville and nearby communities.
What Is the Difference Between Area Codes 904 and 324?
Area codes 904 and 324 serve the same geographic region in northeastern Florida. The 324 area code was introduced on February 26, 2024, to provide additional telephone numbers for the region.
This arrangement is known as an area code overlay. Instead of replacing the existing code, a new code serves the same area.
Here are the main differences:
| Feature | Area code 904 | Area code 324 |
|---|---|---|
| Location | Northeastern Florida | Northeastern Florida |
| Main city | Jacksonville | Jacksonville |
| Introduced | 1965 | 2024 |
| Geographic coverage | Same overlay region | Same overlay region |
| Toll-free? | No | No |
Existing customers with 904 numbers do not need to change their numbers because of the overlay. New telephone lines or services may receive a 324 number instead.
Both codes require ten-digit dialing for local calls in the region. This means you must dial the area code followed by the seven-digit telephone number, even when calling someone nearby.
Who Is Calling Me From a 904 Number?
A call from a 904 number may come from a person or business in Jacksonville or a nearby community. However, the area code alone cannot confirm who is calling or where the caller is currently located.
If you receive an unfamiliar call, consider these practical steps:
- Check the number: Search the complete phone number online to see whether it is associated with a business or reported unwanted calls.
- Listen to voicemail: If the caller leaves a message, review it before deciding whether to return the call.
- Verify the organization: If the caller claims to represent a bank, government agency, or company, use the contact details on its official website.
- Avoid sharing sensitive details: Do not provide passwords, verification codes, or financial information to an unverified caller.
- Block suspicious calls: Use your phone's call-blocking or spam-reporting features when needed.
A 904 number is a legitimate geographic area code, but that does not mean every call from it is safe. Scammers can use caller ID spoofing to make a call appear to come from a local number. The Federal Trade Commission advises consumers not to rely on caller ID alone to verify a caller's identity.
