Frequently Asked Questions about the 713 Area Code
Who called me from a 713 number?
A 713 number is assigned to Houston, Texas, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 713 code to look nearby, so a 713 number doesn't prove the caller is local. Recently, 634 unwanted-call complaints were reported to the FTC for numbers showing the 713 code (61% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 713 a scam area code?
No area code is a scam on its own. 713 is a normal, officially assigned code for Houston, Texas. Spam callers spoof local codes to raise the odds you answer, so 713 on your caller ID says nothing about who is really calling. Recently, 634 unwanted-call complaints were reported to the FTC for numbers showing the 713 code (61% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 713 area code?
Repeated calls from different 713 numbers are usually spoofing: a robocaller rotates through 713 numbers so each call looks local and slips past simple blocks. Recently, 634 unwanted-call complaints were reported to the FTC for numbers showing the 713 code (61% 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 713 number?
If you aren't expecting a 713 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 713 area code?
Block a single 713 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 713 code also stops legitimate local calls, so use it only as a last resort.

What timezone is the 713 area code in?
