Frequently Asked Questions about the 724 Area Code
Who called me from a 724 number?
A 724 number is assigned to New Castle, Pennsylvania, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 724 code to look nearby, so a 724 number doesn't prove the caller is local. Recently, 636 unwanted-call complaints were reported to the FTC for numbers showing the 724 code (52% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 724 a scam area code?
No area code is a scam on its own. 724 is a normal, officially assigned code for New Castle, Pennsylvania. Spam callers spoof local codes to raise the odds you answer, so 724 on your caller ID says nothing about who is really calling. Recently, 636 unwanted-call complaints were reported to the FTC for numbers showing the 724 code (52% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 724 area code?
Repeated calls from different 724 numbers are usually spoofing: a robocaller rotates through 724 numbers so each call looks local and slips past simple blocks. Recently, 636 unwanted-call complaints were reported to the FTC for numbers showing the 724 code (52% 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 724 number?
If you aren't expecting a 724 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 724 area code?
Block a single 724 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 724 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 724?
Area code 724 covers New Castle and the surrounding area in Pennsylvania, spanning 367 cities with about 788,551 residents. No other code overlays this region, so 724 alone identifies the area.

Yes. 724 is an active code in the North American Numbering Plan, assigned by NANPA and in service for New Castle, Pennsylvania. A real code can still show up on spoofed spam calls, so treat unknown 724 calls with normal caution.
What timezone is the 724 area code in?
The 724 area code is in the Eastern Time (ET). Because a number can be kept when someone moves or switches to VoIP, a specific 724 caller may not be in that zone.
