507 Area Code: Rochester, Minnesota

Southern Minnesota is served by the 507 area code, with Rochester as the primary city. Rochester sits in the rolling country of southeastern Minnesota, organized around the Mayo Clinic — one of the largest and most prominent medical centers in the world, anchoring the city's working economy and population for well over a century. The 507 footprint extends through Mankato, Owatonna, Albert Lea, Worthington, and the surrounding southern Minnesota counties.

In records the directory has compiled for 507 numbers, other Minnesota cities — Bloomington, Brooklyn Park, Duluth, and Minneapolis — recur frequently. None of those are inside the 507 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across Minnesota and addresses linked across multiple cities. The directory currently documents 401 distinct prefixes within 507 in detail, a working subset of the prefix population the code carries.

Rochester's median household income runs above the US figure, supported by the wage premium tied to the substantial concentration of medical employment at the Mayo Clinic and the surrounding healthcare ecosystem. Home values come in close to the national median, the city's median age sits close to the US reading, and population places Rochester as one of the larger cities in Minnesota outside the Twin Cities — substantial enough to anchor a regional economy organized almost entirely around the medical sector and the surrounding agricultural counties of southern Minnesota.
