Frequently Asked Questions about the 870 Area Code
Who called me from a 870 number?
A 870 number is assigned to Jonesboro, Arkansas, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 870 code to look nearby, so a 870 number doesn't prove the caller is local. Recently, 382 unwanted-call complaints were reported to the FTC for numbers showing the 870 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 870 a scam area code?
No area code is a scam on its own. 870 is a normal, officially assigned code for Jonesboro, Arkansas. Spam callers spoof local codes to raise the odds you answer, so 870 on your caller ID says nothing about who is really calling. Recently, 382 unwanted-call complaints were reported to the FTC for numbers showing the 870 code (60% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 870 area code?
Repeated calls from different 870 numbers are usually spoofing: a robocaller rotates through 870 numbers so each call looks local and slips past simple blocks. Recently, 382 unwanted-call complaints were reported to the FTC for numbers showing the 870 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 870 number?
If you aren't expecting a 870 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 870 area code?
Block a single 870 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 870 code also stops legitimate local calls, so use it only as a last resort.

What timezone is the 870 area code in?
The 870 area code is in the Central Time (CT). Because a number can be kept when someone moves or switches to VoIP, a specific 870 caller may not be in that zone.
