City population is shown in full. The share of each city inside 920 is measured from Census tract centroids, not estimated from a rate-center match – so a city split between two codes appears on both, at the fraction each one actually holds. The “% of listed-city population” column uses the full populations of the cities listed here.

Frequently Asked Questions about the 920 Area Code
Who called me from a 920 number?
A 920 number is assigned to Green Bay, Wisconsin, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 920 code to look nearby, so a 920 number doesn't prove the caller is local. Recently, 1,566 unwanted-call complaints were reported to the FTC for numbers showing the 920 code (70% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 920 a scam area code?
No area code is a scam on its own. 920 is a normal, officially assigned code for Green Bay, Wisconsin. Spam callers spoof local codes to raise the odds you answer, so 920 on your caller ID says nothing about who is really calling. Recently, 1,566 unwanted-call complaints were reported to the FTC for numbers showing the 920 code (70% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 920 area code?
Repeated calls from different 920 numbers are usually spoofing: a robocaller rotates through 920 numbers so each call looks local and slips past simple blocks. Recently, 1,566 unwanted-call complaints were reported to the FTC for numbers showing the 920 code (70% 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 920 number?
If you aren't expecting a 920 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 920 area code?
Block a single 920 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 920 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 920?
Area code 920 covers Green Bay and the surrounding area in Wisconsin, spanning 165 cities with about 1,308,784 residents. It shares its area with overlay code 274.
When did area code 920 go into service?
Area code 920 went into service on July 26, 1997. It was split off from area code 414.
Is 920 a real area code?
Yes. 920 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Green Bay, Wisconsin. A real code can still show up on spoofed spam calls, so treat unknown 920 calls with normal caution.
What timezone is the 920 area code in?
The 920 area code is in the Central Time (CT). Because a number can be kept when someone moves or switches to VoIP, a specific 920 caller may not be in that zone.
How do I call a 920 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 920 and the seven-digit number. From a mobile phone you can usually just enter +1 920 followed by the number and let the phone add the exit code for you.
