Frequently Asked Questions about the 731 Area Code
Who called me from a 731 number?
A 731 number is assigned to Jackson, Tennessee, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 731 code to look nearby, so a 731 number doesn't prove the caller is local. Recently, 341 unwanted-call complaints were reported to the FTC for numbers showing the 731 code (60% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 731 a scam area code?
No area code is a scam on its own. 731 is a normal, officially assigned code for Jackson, Tennessee. Spam callers spoof local codes to raise the odds you answer, so 731 on your caller ID says nothing about who is really calling. Recently, 341 unwanted-call complaints were reported to the FTC for numbers showing the 731 code (60% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 731 area code?
Repeated calls from different 731 numbers are usually spoofing: a robocaller rotates through 731 numbers so each call looks local and slips past simple blocks. Recently, 341 unwanted-call complaints were reported to the FTC for numbers showing the 731 code (60% 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 731 number?
If you aren't expecting a 731 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 731 area code?
Block a single 731 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 731 code also stops legitimate local calls, so use it only as a last resort.

What timezone is the 731 area code in?
The 731 area code is in the Central Time (CT). Because a number can be kept when someone moves or switches to VoIP, a specific 731 caller may not be in that zone.

From outside the US, dial your country's exit code, then 1 (the US country code), then 731 and the seven-digit number. From a mobile phone you can usually just enter +1 731 followed by the number and let the phone add the exit code for you.
