City population is shown in full. The share of each city inside 924 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.
What counties does area code 924 cover?

Caller ID is easily spoofed, so these figures reflect the number shown on caller ID, not the caller's true location – an area code alone never identifies a caller. The FTC does not verify the facts in these complaints. Source: FTC Do Not Call (DNC) Reported Calls Data, retrieved 2026-08-17.
Frequently Asked Questions about the 924 Area Code
Who called me from a 924 number?
A 924 number is assigned to Rochester, Minnesota, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 924 code to look nearby, so a 924 number doesn't prove the caller is local. Recently, 3 unwanted-call complaints were reported to the FTC for numbers showing the 924 code (0% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 924 a scam area code?
No area code is a scam on its own. 924 is a normal, officially assigned code for Rochester, Minnesota. Spam callers spoof local codes to raise the odds you answer, so 924 on your caller ID says nothing about who is really calling. Recently, 3 unwanted-call complaints were reported to the FTC for numbers showing the 924 code (0% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 924 area code?
Repeated calls from different 924 numbers are usually spoofing: a robocaller rotates through 924 numbers so each call looks local and slips past simple blocks. Recently, 3 unwanted-call complaints were reported to the FTC for numbers showing the 924 code (0% 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 924 number?
If you aren't expecting a 924 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 924 area code?
Block a single 924 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 924 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 924?
Area code 924 covers Rochester and the surrounding area in Minnesota, spanning 261 cities with about 849,078 residents. It shares its area with overlay code 507.
When did area code 924 go into service?
Area code 924 went into service on August 30, 2024. It was added as an overlay of 507, so 924 numbers serve the same area that 507 already covered.
Is 924 a real area code?
Yes. 924 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Rochester, Minnesota. A real code can still show up on spoofed spam calls, so treat unknown 924 calls with normal caution.
What timezone is the 924 area code in?
The 924 area code is in the Central Time (CT). Because a number can be kept when someone moves or switches to VoIP, a specific 924 caller may not be in that zone.
How do I call a 924 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 924 and the seven-digit number. From a mobile phone you can usually just enter +1 924 followed by the number and let the phone add the exit code for you.
