Jacksonville, Florida Area Codes: 904 and 324
Jacksonville, Florida's area code is 904, with 324 assigned as the overlay. Learn the neighborhoods 904 covers, the time zone, and how to get a local number.
Jacksonville, Florida runs on area code 904 — the number of the First Coast, from downtown Jacksonville to the beaches and St. Augustine. A second code, 324, has been assigned as the region’s future overlay.
Whether you’re verifying a 904 number, setting up a local business line for the Jacksonville market, or wondering why a nearby contact has a 386 prefix, this guide covers it.
What’s the area code for Jacksonville?
Jacksonville and northeast Florida are served by area code 904, with 324 assigned as the overlay for the same region under the North American Numbering Plan (NANP).
| Code | Status | Coverage |
|---|---|---|
| 904 | Active | Jacksonville + First Coast (Duval, St. Johns, Clay, Nassau, Putnam, Baker counties) |
| 324 | Assigned overlay | Same 904 territory; activates when 904 nears exhaustion |
Jacksonville sits in the Eastern Time Zone (ET) — UTC−5 in winter, UTC−4 during Daylight Saving Time.
For regional context: the Daytona Beach / north-central Florida region uses 386, the Florida Panhandle (Tallahassee, Pensacola) uses 850, and Orlando uses 407/689.
Jacksonville neighborhoods in the 904 area code
Because Jacksonville is the largest city by land area in the contiguous US, the 904 code stretches across a wide metro and the surrounding First Coast.
- Downtown / Northbank & Southbank — the urban core along the St. Johns River
- Riverside / Avondale — historic districts west of downtown
- San Marco — riverside shopping and dining south of downtown
- Southside / Tinseltown — major retail and office corridor
- Mandarin — large residential area in the south
- Arlington — established neighborhoods east of the river
- The Beaches — Jacksonville Beach, Atlantic Beach, Neptune Beach
- Ponte Vedra Beach — coastal community in St. Johns County
- Orange Park — suburb in Clay County
- St. Augustine — the nation’s oldest city, in St. Johns County
- Fernandina Beach / Amelia Island — Nassau County
- Palatka — Putnam County, southwest of Jacksonville
History of the 904 area code
The 904 code has covered northeast Florida for decades, gradually shrinking as new codes split off to serve a growing state.
Original north Florida code. For years, 904 covered a huge stretch of north Florida — from the Panhandle through Jacksonville and down toward the Daytona and Gainesville areas.
1998 — 850 splits off the Panhandle. As Florida’s number demand grew, the western Panhandle (Tallahassee, Pensacola, Panama City) was carved out into area code 850, leaving 904 covering north-central and northeast Florida.
2001 — 386 splits off the Daytona/Gainesville region. A second split created area code 386 for the Daytona Beach, DeLand, Lake City, and Gainesville areas. After this, 904 was reduced to its current footprint: Jacksonville and the immediate First Coast counties.
324 — the assigned overlay. To prepare for future exhaustion of 904, NANPA has assigned 324 as an all-services overlay for the 904 region. When activated, it adds numbers without changing anyone’s existing 904 number, and both codes share the same geography.

Why people confuse 904 with 386
A common mix-up: searchers assume 386 is a Jacksonville code because it’s a nearby north-Florida number. It isn’t.
- 904 = Jacksonville and the First Coast (Duval, St. Johns, Clay, Nassau).
- 386 = Daytona Beach, Deltona, DeLand, Palm Coast, and Lake City — the region that split off from 904 in 2001.
So a 386 caller is in the Daytona/DeLand area, not Jacksonville. For a true Jacksonville local presence, you want a 904 number (or 324 once the overlay is active).
Jacksonville area code spam and scams
Like every large metro, the 904 code is targeted by caller-ID spoofing — scammers display a fake local 904 number to raise the odds a resident answers.
Common patterns nationwide include utility “shutoff” threats, IRS or tax-debt impersonation, and Medicare or benefits scams aimed at retirees. Legitimate agencies do not demand immediate payment by gift card or wire transfer. If in doubt, hang up and call the organization back on its official published number.
The FCC-mandated STIR/SHAKEN framework authenticates outbound calls with an attestation level — A (fully verified), B (partial), or C (unverified). Spoofed calls receive low or no attestation and get flagged as “Spam Likely.”
A DialPhone 904 number sends outbound calls with A-attestation, so your business calls reach customers verified — not screened. See the FCC’s guidance: fcc.gov/consumers/guides/spoofing-and-caller-id.

Jacksonville area code FAQ
Jacksonville area code FAQ
What is the area code for Jacksonville, Florida?
Jacksonville's area code is **904**. It covers the city of Jacksonville and the surrounding First Coast region of northeast Florida, including St. Augustine, Orange Park, Fernandina Beach, and Palatka.
**324** has been assigned by the North American Numbering Plan as a future overlay for the same 904 region, to be activated when the 904 number pool nears exhaustion. When active, 324 will cover the exact same geography as 904 — there is no neighborhood split.
Is 386 a Jacksonville area code?
No. **386 is not Jacksonville** — it serves the Daytona Beach and north-central Florida region (Daytona Beach, Deltona, DeLand, Palm Coast, and Lake City). It split off from 904 in 2001.
If you see a 386 number, the caller is in the Daytona/DeLand area, roughly 90 miles south of Jacksonville — not in Jacksonville proper. Jacksonville uses 904 (with 324 as the assigned overlay).
What cities are in the 904 area code?
The 904 area code covers Jacksonville and the wider First Coast: St. Augustine, Orange Park, Fernandina Beach (Amelia Island), Palatka, Ponte Vedra Beach, Atlantic Beach, Neptune Beach, and Jacksonville Beach. It spans Duval, St. Johns, Clay, Nassau, Putnam, and Baker counties in northeast Florida.
What time zone is the 904 area code in?
The 904 area code is in the **Eastern Time Zone** (ET) — UTC−5 in winter and UTC−4 during Daylight Saving Time. All of northeast Florida observes Eastern Time, the same as Miami, Orlando, and the US East Coast.
Are 904 calls spam?
904 itself is a legitimate Jacksonville area code. The risk is **spoofing** — scammers fake a local 904 caller ID so residents are more likely to answer. Treat unexpected calls demanding immediate payment, gift cards, or personal information as suspicious, and verify by calling the organization back on its published number.
The FCC's STIR/SHAKEN framework authenticates outbound calls. A DialPhone 904 number sends calls with A-attestation — the highest verification level — so your business calls are less likely to be flagged as 'Spam Likely.'
Can I get a Jacksonville 904 number without a Florida office?
Yes. Virtual (VoIP) numbers aren't tied to a physical address. A business anywhere can get a 904 number through a cloud phone provider and route calls to any device.
DialPhone assigns available Jacksonville numbers in minutes — no Florida office, no hardware, no long-term contract. Outbound calls display the local 904 caller ID and ring on mobile, desktop, or a team queue.
