City population is shown in full. The share of each city inside 324 is measured from Census tract centroids, not estimated from a rate-center match – so a city split between two codes appears on both, at the fraction each one actually holds. The “% of listed-city population” column uses the full populations of the cities listed here.
What counties does area code 324 cover?

Caller ID is easily spoofed, so these figures reflect the number shown on caller ID, not the caller's true location – an area code alone never identifies a caller. The FTC does not verify the facts in these complaints. Source: FTC Do Not Call (DNC) Reported Calls Data, retrieved 2026-08-17.
Frequently Asked Questions about the 324 Area Code
Who called me from a 324 number?
A 324 number is assigned to Jacksonville, Florida, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 324 code to look nearby, so a 324 number doesn't prove the caller is local. Recently, 40 unwanted-call complaints were reported to the FTC for numbers showing the 324 code (40% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 324 a scam area code?
No area code is a scam on its own. 324 is a normal, officially assigned code for Jacksonville, Florida. Spam callers spoof local codes to raise the odds you answer, so 324 on your caller ID says nothing about who is really calling. Recently, 40 unwanted-call complaints were reported to the FTC for numbers showing the 324 code (40% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 324 area code?
Repeated calls from different 324 numbers are usually spoofing: a robocaller rotates through 324 numbers so each call looks local and slips past simple blocks. Recently, 40 unwanted-call complaints were reported to the FTC for numbers showing the 324 code (40% flagged as robocalls). Blocking one number rarely helps; voicemail screening, your carrier spam filter, and the Do Not Call Registry work better.
Should I answer an unknown 324 number?
If you aren't expecting a 324 call, let it ring to voicemail. Legitimate callers leave a message, most robocallers hang up when no one picks up, and answering can mark your number as active and bring more calls.
How do I block calls from the 324 area code?
Block a single 324 number from your recent-calls list (iPhone: tap the number, then Block this Caller; Android: tap the number, then Block or report spam). To cut the volume, turn on Silence Unknown Callers on iPhone or spam protection on Android, enable spam filtering from your carrier, and register at DoNotCall.gov. Blocking the entire 324 code also stops legitimate local calls, so use it only as a last resort.

Area code 324 covers Jacksonville and the surrounding area in Florida, spanning 40 cities with about 1,614,767 residents. It shares its area with overlay code 904.
When did area code 324 go into service?

Is 324 a real area code?
Yes. 324 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Jacksonville, Florida. A real code can still show up on spoofed spam calls, so treat unknown 324 calls with normal caution.
What timezone is the 324 area code in?
The 324 area code is in the Eastern Time (ET). Because a number can be kept when someone moves or switches to VoIP, a specific 324 caller may not be in that zone.
How do I call a 324 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 324 and the seven-digit number. From a mobile phone you can usually just enter +1 324 followed by the number and let the phone add the exit code for you.
