Frequently Asked Questions about the 970 Area Code
Who called me from a 970 number?
A 970 number is assigned to Fort Collins, Colorado, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 970 code to look nearby, so a 970 number doesn't prove the caller is local. Recently, 1,494 unwanted-call complaints were reported to the FTC for numbers showing the 970 code (76% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 970 a scam area code?
No area code is a scam on its own. 970 is a normal, officially assigned code for Fort Collins, Colorado. Spam callers spoof local codes to raise the odds you answer, so 970 on your caller ID says nothing about who is really calling. Recently, 1,494 unwanted-call complaints were reported to the FTC for numbers showing the 970 code (76% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 970 area code?
Repeated calls from different 970 numbers are usually spoofing: a robocaller rotates through 970 numbers so each call looks local and slips past simple blocks. Recently, 1,494 unwanted-call complaints were reported to the FTC for numbers showing the 970 code (76% 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 970 number?
If you aren't expecting a 970 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 970 area code?
Block a single 970 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 970 code also stops legitimate local calls, so use it only as a last resort.

Yes. 970 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Fort Collins, Colorado. A real code can still show up on spoofed spam calls, so treat unknown 970 calls with normal caution.
What timezone is the 970 area code in?
The 970 area code is in the Mountain Time (MT). Because a number can be kept when someone moves or switches to VoIP, a specific 970 caller may not be in that zone.

From outside the US, dial your country's exit code, then 1 (the US country code), then 970 and the seven-digit number. From a mobile phone you can usually just enter +1 970 followed by the number and let the phone add the exit code for you.
