The 507 area code serves the southern third of Minnesota, anchored by Rochester, home of the world-famous Mayo Clinic, and the regional city of Mankato. Created in 1954 when it split from an earlier configuration, 507 covers a broad band of farmland and small cities across the bottom of the state.

Geographic Coverage
The 507 area code covers southern Minnesota, from Rochester in the southeast – near the Mississippi River city of Winona – west through Owatonna, Faribault, and the meatpacking city of Austin, to Mankato in the center and Worthington and Albert Lea in the far south. It borders Iowa to the south and Wisconsin to the east across a rich agricultural region.
Time Zone
The 507 area code observes Central Time (CT). Clocks follow Central Standard Time (UTC−6) in winter and shift to Central Daylight Time (UTC−5) from mid-March through early November. All of Minnesota is on Central Time. From the West Coast, this region is two hours ahead of Pacific Time, so a 9:00 AM call in California reaches a 507 number at 11:00 AM local time.
Tip: Business hours across the 507 region generally run 9:00 AM to 5:00 PM Central Time, Monday through Friday.
How to Dial a 507 Number
Area code 507 is not part of an overlay, so it has traditionally allowed 7-digit local dialing. However, 10-digit dialing is now the recommended nationwide standard, and dialing the full 10-digit number (507 + the line number) always works reliably. For international callers, dial your country’s exit code, then +1 (the North American country code), then 507, followed by the seven-digit local number.
Scam Alerts for the 507 Area Code
Like every U.S. area code, 507 has been used by scammers who spoof local numbers to appear trustworthy. Residents in Rochester, Mankato, Winona, Owatonna, Austin, Albert Lea, Faribault, Worthington should stay alert to the following common tactics:
| Scam Type | What to Watch For |
|---|---|
| IRS / Tax Scams | Callers claiming you owe back taxes and threatening arrest unless you pay immediately. |
| Utility Shut-off | Fake Xcel Energy callers demanding instant payment to keep your power on. |
| Medicare / Health Scam | Robocalls seeking Medicare numbers under the guise of free braces or test kits. |
| Farm / Equipment Scam | Fraudulent online listings for tractors or farm equipment aimed at rural buyers. |
If you receive a suspicious call from a 507 number, take these steps to protect yourself:
- Do not share personal information such as Social Security numbers, bank details, or passwords over the phone.
- Hang up and verify by calling the organization back using an official number from its website.
- Report the call to the FTC at reportfraud.ftc.gov and to the Minnesota Attorney General’s Office.
- Block the number and consider registering with the National Do Not Call Registry.
Red Flag: Legitimate agencies such as the IRS, Social Security Administration, or your local utility company (Xcel Energy or Minnesota Power) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 507 caller making such a demand is a scammer.
