Frequently Asked Questions about the 835 Area Code
Who called me from a 835 number?
A 835 number is assigned to Allentown, Pennsylvania, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 835 code to look nearby, so a 835 number doesn't prove the caller is local. Recently, 98 unwanted-call complaints were reported to the FTC for numbers showing the 835 code (80% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 835 a scam area code?
No area code is a scam on its own. 835 is a normal, officially assigned code for Allentown, Pennsylvania. Spam callers spoof local codes to raise the odds you answer, so 835 on your caller ID says nothing about who is really calling. Recently, 98 unwanted-call complaints were reported to the FTC for numbers showing the 835 code (80% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 835 area code?
Repeated calls from different 835 numbers are usually spoofing: a robocaller rotates through 835 numbers so each call looks local and slips past simple blocks. Recently, 98 unwanted-call complaints were reported to the FTC for numbers showing the 835 code (80% 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 835 number?
If you aren't expecting a 835 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 835 area code?
Block a single 835 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 835 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 835?

Is 835 a real area code?
Yes. 835 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Allentown, Pennsylvania. A real code can still show up on spoofed spam calls, so treat unknown 835 calls with normal caution.
What timezone is the 835 area code in?
The 835 area code is in the Eastern Time (ET). Because a number can be kept when someone moves or switches to VoIP, a specific 835 caller may not be in that zone.
