Frequently Asked Questions about the 320 Area Code
Who called me from a 320 number?
A 320 number is assigned to St. Cloud, Minnesota, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 320 code to look nearby, so a 320 number doesn't prove the caller is local. Recently, 299 unwanted-call complaints were reported to the FTC for numbers showing the 320 code (68% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 320 a scam area code?
No area code is a scam on its own. 320 is a normal, officially assigned code for St. Cloud, Minnesota. Spam callers spoof local codes to raise the odds you answer, so 320 on your caller ID says nothing about who is really calling. Recently, 299 unwanted-call complaints were reported to the FTC for numbers showing the 320 code (68% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 320 area code?
Repeated calls from different 320 numbers are usually spoofing: a robocaller rotates through 320 numbers so each call looks local and slips past simple blocks. Recently, 299 unwanted-call complaints were reported to the FTC for numbers showing the 320 code (68% 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 320 number?
If you aren't expecting a 320 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 320 area code?
Block a single 320 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 320 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 320?
Area code 320 covers St. Cloud and the surrounding area in Minnesota, spanning 187 cities with about 356,208 residents. No other code overlays this region, so 320 alone identifies the area.
Is 320 a real area code?
Yes. 320 is an active code in the North American Numbering Plan, assigned by NANPA and in service for St. Cloud, Minnesota. A real code can still show up on spoofed spam calls, so treat unknown 320 calls with normal caution.
What timezone is the 320 area code in?
The 320 area code is in the Central Time (CT). Because a number can be kept when someone moves or switches to VoIP, a specific 320 caller may not be in that zone.
How do I call a 320 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 320 and the seven-digit number. From a mobile phone you can usually just enter +1 320 followed by the number and let the phone add the exit code for you.
