The 507 area code serves southern Minnesota, including Rochester, Mankato, Winona, Austin, Albert Lea, Northfield, Owatonna, and Worthington. It has been in service since January 1, 1954, runs on Central Time, and was Minnesota’s third area code. In 2024, overlay code 924 was added to the same region to keep up with demand for new numbers.
What Is the 507 Area Code?
The North American Numbering Plan (NANP) uses area code 507 minnesota to serve the southern fifth of Minnesota. In 1954, officials created area code by splitting parts of the older 218 and 612 area codes, making it one of Minnesota’s original three area codes.
Where Is the Area Code Located?
The area code 507 covers southern Minnesota, stretching from the Iowa border north toward the edge of the Twin Cities metro. It borders several other numbering plan areas: 612 to the north (historically), 320 and 651 to the northeast, 952 near the Twin Cities suburbs, and out-of-state codes including 605 (South Dakota), 608 (Wisconsin), and 641 and 712 (Iowa).
Major Cities in the Area Code
The area code spans roughly 30+ counties, including Olmsted, Blue Earth, Winona, Mower, Rice, Steele, Nicollet, and Freeborn counties, and covers a large number of ZIP codes across the region.
History of the Area Code
Area code 507 location went into service on January 1, 1954, making it the third area code created in Minnesota, after 218 and 612 (both introduced in 1947). It was formed by combining the southwestern portion of 218 with the southern portion of 612.
As the Twin Cities metro grew and 612 was later split into additional codes (651, 763, 952), the northern boundary of 507 shifted slightly so that fast-growing communities near Minneapolis–St. Paul stayed connected to the metro numbering plan instead.
Is a Legitimate Area Code, or a Scam?
The 507 area code location itself is completely legitimate; it’s a standard geographic area code, not a premium-rate or international scam prefix like 809 or 900. That said, any area code, including 507, can be spoofed by scammers who fake a local caller ID to appear more trustworthy. A call showing a 507 number doesn’t guarantee it’s actually coming from southern Minnesota. If you receive an unexpected call from a number asking for money, gift cards, or personal information, treat it with the same caution you’d apply to any unsolicited call, regardless of area code.
Area Code Time Zone
The area code of 507 follows the Central Time Zone (America/Chicago). It also observes daylight saving time, just like the rest of Minnesota.

Conclusion
The 507 area code has anchored southern Minnesota’s phone system for over 70 years, connecting cities like Rochester, Mankato, Winona, and Albert Lea since 1954. While the addition of the 924 overlay in 2024 changed how residents dial (10 digits now, even for local calls), it didn’t change what represents: a stable, legitimate geographic area code tied to a real region, not a scam prefix or virtual number block.
