Frequently Asked Questions about the 934 Area Code
Who called me from a 934 number?
A 934 number is assigned to Brentwood, New York, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 934 code to look nearby, so a 934 number doesn't prove the caller is local. Recently, 77 unwanted-call complaints were reported to the FTC for numbers showing the 934 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 934 a scam area code?
No area code is a scam on its own. 934 is a normal, officially assigned code for Brentwood, New York. Spam callers spoof local codes to raise the odds you answer, so 934 on your caller ID says nothing about who is really calling. Recently, 77 unwanted-call complaints were reported to the FTC for numbers showing the 934 code (52% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 934 area code?
Repeated calls from different 934 numbers are usually spoofing: a robocaller rotates through 934 numbers so each call looks local and slips past simple blocks. Recently, 77 unwanted-call complaints were reported to the FTC for numbers showing the 934 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 934 number?
If you aren't expecting a 934 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 934 area code?
Block a single 934 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 934 code also stops legitimate local calls, so use it only as a last resort.
