The 324 area code is the newest area code in Florida — a 2024 overlay layered directly on top of Jacksonville's beloved 904. It covers the exact same northeast-Florida territory, from Jacksonville and the Beaches down to St. Augustine and up to the Georgia line. If you have been offered a 324 number, you are still firmly in the 904's footprint; 324 is simply the new code being issued as 904 runs out of numbers.

This guide explains where 324 reaches, why Jacksonville needed a second code, exactly what changes for you, the "is it a Colombia or Mexico number?" mix-up, how dialing and texting work, how to stay safe, and how to get a 324 number from anywhere.

Where is the 324 area code?

The 324 area code location is northeast Florida — the same region as 904. It is centered on Jacksonville and spreads across Duval, St. Johns, Clay, Nassau, Baker, and Putnam counties.

Cities and communities inside the 324 / 904 footprint include:

Why Jacksonville got the 324 overlay

For decades, northeast Florida ran entirely on 904 — a code Jacksonville residents are genuinely attached to, as the popular "904ever" slogan shows. But the region grew, mobile numbers multiplied, and by 2024 the 904 number pool was projected to run out.

Rather than split the region — which would have forced half of northeast Florida to change their numbers — regulators added the 324 overlay, in service since February 26, 2024. The neighboring 904 area code keeps every existing number exactly as it is; 324 simply provides a fresh pool of numbers for new lines across the same area.

904 vs 324: what actually changes

Comparison of the 904 and 324 area codes in Jacksonville

This is the question most Jacksonville residents and businesses actually have, so here is the short version:

  • Your existing 904 number does not change. Nobody has to give up their 904.
  • New phone lines may be assigned 324 instead of 904, depending on what's available.
  • Ten-digit dialing is now required for everyone — you must dial the area code plus the seven-digit number on every call, even local ones.
  • Calls between 904 and 324 are still local. Both codes cover the identical area, so there is no long-distance charge between them.

In short: 904 and 324 are two codes for one community. A 324 number is just as local as a 904 one.

Is 324 a Colombia or Mexico number?

Because "324" also appears in international dialing, some people search whether it belongs to Colombia, Mexico, or Canada. To be clear: as a North American area code, 324 is a US code for Jacksonville, Florida. A US 324 number is written +1 324 XXX XXXX.

The confusion comes from Colombia, where mobile numbers are written with a +57 country code followed by digits like 324 — that is a completely different format. If a "+1 324" number is contacting you, it is a Jacksonville-area US number, not an international one.

Northeast Florida's economy

A 324 or 904 number connects you to one of the Southeast's most dynamic markets. Jacksonville's economy runs on:

  • Logistics and ports — JAXPORT is a major Atlantic container and automobile port, anchoring a large logistics and distribution sector.
  • Military and defense — Naval Station Mayport and NAS Jacksonville give the region one of the largest Navy concentrations in the country.
  • Finance and fintech — major financial-services and payments employers are headquartered in Jacksonville.
  • Tourism — St. Augustine, Amelia Island, and the Beaches drive a steady hospitality economy.

For logistics firms, contractors, financial services, and hospitality businesses, a local northeast-Florida number is a credibility signal.

Dialing, texting and time zone for 324

The 324 area code time zone is Eastern Time (ET) — EST (UTC−5) in winter and EDT (UTC−4) in summer, the same clock as Miami and New York. Calls and texts to a 324 number both use ten digits.

ActionFormat
Call within the US / Canada1 324 XXX XXXX
Call from outside North America+1 324 XXX XXXX
Text message (SMS)+1 324 XXX XXXX
Within northeast Florida324 XXX XXXX (ten digits required)

Putting a 324 number to work for your business

Because 324 is the code being issued to new lines, it is a natural fit for a business just setting up in Jacksonville — you get a genuinely local northeast-Florida number without competing for scarce 904 inventory. A local code reads as familiar and lifts answer rates over an unknown out-of-state or toll-free line.

You do not need a Jacksonville office to claim one. A cloud phone provider can assign you a 324 number that rings and texts on your existing devices and routes calls anywhere. With a provider like My Country Mobile, you can pick a 324 line, set up routing, an auto-attendant, and voicemail, and be live in minutes.

Spotting fake 324 and 904 calls

Flagged 324 spam call beside safety tips

Because 324 is new, scammers know many people don't recognize it yet — which makes spoofed 324 calls and texts especially worth scrutinizing. Fraudsters fake a local prefix so a call looks like it's from northeast Florida.

A few habits keep you safe:

  • Let unknown 324 or 904 calls go to voicemail, and don't tap links in unexpected texts.
  • Never share one-time codes, card numbers, or login details with an inbound caller or texter.
  • Be skeptical of "package delivery," "your account is locked," or prize-style messages 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 as "Spam Risk."

Key takeaways

  • 324 is the new overlay on Jacksonville's 904, in service since February 2024.
  • It covers the same northeast-Florida region — Jacksonville, the Beaches, St. Augustine.
  • Existing 904 numbers don't change; new lines may get 324, and ten-digit dialing is required.
  • It is a US Eastern-Time code — not a Colombia, Mexico, or Canada number.
  • You can get a 324 number from the cloud without a Florida address.
