Area Code 924

Rochester and surrounding communities

Area code 924 is Rochester’s newest overlay. It went live in August 2024 across the same territory as 507, from Albert Lea, Austin, Belle Plaine and beyond. New numbers are only starting to be issued, so a 924 caller ID is still rare: this guide covers what the code is, who might be calling, and what it means for your own number.

Who called me from area code 924?

Quick answerA real 924 call comes from Rochester or nearby communities, but 924 numbers are brand new and still rare, so treat an unfamiliar one with extra care: caller ID can be spoofed. If there’s no voicemail, let it go: legitimate callers leave messages.
  • No voicemail? Let it go. Real callers leave messages.
  • Recognize the pattern? Check the number in the prefix lookup.
  • Getting repeats? ActiveArmor® blocks and labels them automatically.
  • Same prefix calling again? Compare it against this month’s most-reported prefixes from the region, right on this page.
  • Curious who issued a number? Every assigned prefix belongs to a carrier - the registry will name each 924 prefix as it comes into service.

No 924 spam patterns have been reported yet: the code is too new. Spoofers imitate the established local codes first, so the current patterns below come from the 507 board.

Is area code 924 a scam?

No. 924 is a legitimate Rochester area code.

It went live in August 2024 as the newest layer over the Rochester region, serving the exact same territory as 507. But legitimacy of the code says nothing about any single call. Scammers spoof local numbers constantly.

The code is realLive since August 2024; carrier prefixes are only beginning to roll out, so 924 numbers are still rare.

Scam texts from area code 924 numbers

The most common area code 924 text scam is the “wrong number” opener: a friendly message that pretends to know you, then moves the chat to WhatsApp and eventually to an investment pitch.

Scripts currently circulating:

“U at home?” · “Are you busy tomorrow?” · “How are you doing?”
Delivery-problem and job-offer texts that link out to a login page

Don’t reply. A response marks your number as live. Forward scam texts to 7726 (SPAM), and AT&T ActiveArmor® filters known senders automatically.

How number spoofing works in area code 924

Caller ID is easy to forge. Spoofing fakes the number a call displays. The real owner of that 924 number isn’t involved and usually has no idea. That’s why blocking one number rarely stops the calls.

  • A call from a number almost identical to yours(same 924 and prefix) is “mirror spoofing.” A missed call from your own number is never worth returning.
  • Strangers calling you back saying you called them?Your 924 number is being spoofed. It typically passes within days, and you don’t need a new number. Report it at reportfraud.ftc.gov.
  • The caller-ID checkmark:AT&T verifies network calls (STIR/SHAKEN). A verified mark means the displayed number wasn’t faked. No mark doesn’t always mean scam, but treat it with more caution.

Spoofed or not, the rule holds: unexpected caller, no voicemail? Let it go.

924 area code prefix & carrier lookup

The three digits after the area code identify the carrier a number was issued to. 924 is so new that few or no carrier prefixes are in service yet: the registry below shows the standard service codes every area code reserves. Carrier prefixes will appear here as numbers ship; the guide 507 board shows what a mature registry for this region looks like.

This isn’t a reverse phone lookup: no legitimate free service can tell you who owns a specific number. What a prefix does show, once assigned: the carrier that issued it, whether it’s wireless, landline or VoIP, and the community it belongs to.

The 924, explained

Area code 924: more than a number in Rochester

In Rochester, a new area code is a population milestone. The 924 went live in August 2024, the second code layered over the same territory as 507, and the clearest sign yet of how the region keeps growing. Carrying one today marks you as one of the area’s newest arrivals: the numbers are only beginning to ship.

The map tells its own story: Rochester and surrounding communities, one territory now served by 507 together with 924. Nothing about the coverage changes; the region simply has a deeper pool of numbers.

Keeping a 924 matters here. An existing 924 number ports to a new phone, a new carrier, or a new AT&T line, and stays yours anywhere in the U.S.

A short history of area code 924

Approved as numbering relief for the 507 region and live since August 2024, 924 is the second code to serve this territory. It exists for one reason: the region keeps growing, and the 507 pool of assignable numbers was running low.

Area code 924 FAQ

What area code is 924?
924 is the newest area code for Rochester and the surrounding communities in Minnesota. It went live in August 2024 and covers the exact same territory as 507.
Is area code 924 real or a scam?
924 is a legitimate Minnesota area code, but it is brand new and numbers are still rare. If you get a 924 call today and you don’t know anyone with a new local number, be cautious: spoofing a new code is a known scam tactic. AT&T ActiveArmor labels suspected spam automatically.
Why did the 507 region get another area code?
Growth. The 507 pool was projected to run out of assignable numbers, so regulators approved 924 as an all-services overlay. Nothing changes for existing numbers; new lines simply start drawing from the new code.
Does 924 change my existing number?
No. Overlays never change existing numbers. Your 507 number stays exactly as it is; 924 only affects newly issued numbers.
How do I get a 924 number?
You don’t choose it directly: carriers assign numbers from whichever local code has inventory. As the older pool empties, new AT&T lines in the region will increasingly come with 924. There is no fee or action needed.
What area does 924 cover?
The full 507 territory: Blue Earth, Brown, Cottonwood, Dodge, Faribault and Fillmore and 22 more counties, including Albert Lea, Austin, Belle Plaine and the communities listed on this page.
When did 924 go live?
August 2024. It was approved as relief for the 507 numbering region, and carriers began activating it then. Numbers are still being issued gradually.
What time zone is area code 924?
Central Time: UTC-6 in winter, UTC-5 during daylight saving. The live local time is at the top of this page.
How do I dial a 924 number?
Dial all 10 digits: 924 plus the seven-digit number, the same as every code in the region. From outside the U.S., add the +1 country code first.
Why did I get a call from a 924 number?
Either someone with a brand-new local number, or a spoofed caller ID. Because 924 numbers are still scarce, an unfamiliar 924 call deserves more suspicion than a 507 call. Let it go to voicemail; real callers leave messages.
Is 924 a toll-free number?
No. 924 is a geographic area code for the Rochester region, not a toll-free prefix. U.S. toll-free numbers start with 800, 888, 877, 866, 855, 844 or 833.
What’s the difference between 924 and 507?
Age, and nothing else that matters day to day. 507 is the region’s established code; 924 is the 2024 newcomer. They cover the same map, calls between them are local, and both dial with 10 digits.
Can I keep a 924 number if I move?
Yes. Numbers port: a 924 number goes with you to a new phone, a new carrier or a new city anywhere in the U.S., just like any other area code.
Why did I get a text message from a 924 number?
Treat it carefully. Scam texts often rotate onto new codes because the numbers have no reputation yet. Don’t reply or tap links; forward the text to 7726 (SPAM) and delete it. AT&T ActiveArmor filters known scam senders automatically.
Will a 924 number work everywhere?
Yes. It’s a standard North American number: calls, texts and apps treat it like any local number. Some older web forms may not recognize very new codes at first; that resolves as databases update.
