507 area code southern Minnesota, Rochester to Worthington
Area code 507 covers the southern fifth of Minnesota, serving cities and towns including Rochester, Winona, Mankato, Austin, Owatonna, Faribault, and Worthington. The same geography also carries area code 924, an overlay added in 2024, so a new number in the region may begin with either 507 or 924. Here is where it reaches, what that means for you, and how a small team gets a 507 number without a Minnesota address.

Got a call from a 507 number? A 507 number was issued in southern Minnesota, but the person placing the call could be anywhere, since phone numbers travel with their owners. Area code 507 covers a wide region from Rochester and Winona in the east to Worthington and Fairmont near the Iowa border. If you missed the call, a 507 number is most likely connected to that part of the state.
The overlay
507 or 924? Same towns.
Area code 507 was created in 1954, drawn from the southwestern portion of area code 218 and the southern portion of area code 612, becoming the third area code established in Minnesota. It served southern Minnesota as the sole code for the region for decades. In August 2022, the North American Numbering Plan Administrator forecast that 507 would exhaust its available central office codes by 2025. The Minnesota Public Utilities Commission approved area code 924 as an all-service overlay on March 30, 2023, making it the first area code overlay complex in Minnesota.
Ten-digit dialing became required in July 2024, and new 924 numbers became assignable on August 30, 2024. For a business, the overlay means a customer in Rochester or Mankato may now have either a 507 or a 924 number, and both prefixes reach the same region. An existing 507 number keeps working without any changes.

In practice
What a 507 number does for a small team
A local number is the easy part. What matters is what happens when it rings. Here is one ordinary day for a three-person HVAC company working out of Rochester, with one 507 number on the van and the website.
- 7:30 am
A customer calls before the first job starts. All three phones ring at once, in the app on each tech's phone and in a browser tab at the office.
- 10:15 am
Two techs are already on jobs and the third is on another call. The incoming call joins a short queue with hold music until the first person is free.
- 10:20 am
A voicemail arrives by email with a recording and a transcript; the message says 'Furnace repair needed, calling from Owatonna.'
- 5:00 pm
The schedule flips to after-hours, an emergency option forwards to the owner's cell, and holidays are already marked on the calendar.
- Any time
Every call shows up in one shared list, and nobody's personal cell number ever reaches a customer.

Questions
507 area code, answered
Where is the 507 area code?
Area code 507 covers the southern fifth of Minnesota, a wide region that includes Rochester and Winona in the southeast, Mankato and North Mankato in the south-central corridor, and Austin, Worthington, and Fairmont closer to the Iowa border. The northern edge of the code borders several other Minnesota codes including 320, 651, and 952. The same territory is also served by overlay area code 924.
What is area code 924 and how does it relate to 507?
Area code 924 is an overlay of 507, meaning both codes cover exactly the same geographic area in southern Minnesota. The Minnesota Public Utilities Commission approved 924 on March 30, 2023, after the region was forecast to run short of available 507 numbers. New 924 numbers became assignable on August 30, 2024, making it the first overlay complex in Minnesota.
Does the 507 area code include Rochester?
Yes. Rochester is the largest city in the 507 and 924 region. The code also covers Mankato, Austin, Winona, Owatonna, Faribault, Northfield, Worthington, Fairmont, Albert Lea, and North Mankato, along with the broader southern Minnesota region.
Can I get a 507 number if I am not in Minnesota?
Yes. A Tonet number is an internet-based number and is not tied to a street address or a phone line, so a business anywhere in the US, or a team working for Minnesota customers from abroad, can take a 507 number and answer it in the app, in a browser or on a desk phone.
How much does a 507 business number cost?
The number itself is $2.50 a month. Users are $10 a month each on Pay As You Go, plus 1 cent a minute for calls and 3 cents a text, or $15 a month each on Unlimited, with US calls and texts included under a fair-use policy. Billing is by the day, there is no contract, no setup fee and no seat minimum, and $15 gets you started.
Can I keep my existing 507 number?
Yes. Porting a number to Tonet costs nothing. Most ports complete in 7 to 10 business days, some carriers take a few weeks, and the releasing carrier controls the timing. Your number keeps working with your current provider until the switch, so there is no downtime.
How fast can I get a 507 number set up?
About five minutes. Sign up, add $15, search 507 in the dashboard and pick a number. It rings right away in the app or in a browser tab. A desk phone takes a few more minutes to register.
Why do I have to dial ten digits for 507 numbers?
Ten-digit dialing became required in July 2024, when area code 924 was added as an overlay covering the same towns as 507. When two different area codes share the same geography, seven-digit dialing would be ambiguous, so all calls in the region now require the full ten digits including the area code.
