Frequently Asked Questions about the 904 Area Code
Who called me from a 904 number?
A 904 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 904 code to look nearby, so a 904 number doesn't prove the caller is local. Recently, 1,108 unwanted-call complaints were reported to the FTC for numbers showing the 904 code (59% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 904 a scam area code?
No area code is a scam on its own. 904 is a normal, officially assigned code for Jacksonville, Florida. Spam callers spoof local codes to raise the odds you answer, so 904 on your caller ID says nothing about who is really calling. Recently, 1,108 unwanted-call complaints were reported to the FTC for numbers showing the 904 code (59% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 904 area code?
Repeated calls from different 904 numbers are usually spoofing: a robocaller rotates through 904 numbers so each call looks local and slips past simple blocks. Recently, 1,108 unwanted-call complaints were reported to the FTC for numbers showing the 904 code (59% 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 904 number?
If you aren't expecting a 904 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 904 area code?
Block a single 904 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 904 code also stops legitimate local calls, so use it only as a last resort.
