Area code 651 covers the eastern quadrant of the Minneapolis, Saint Paul metropolitan area, extending from the urban core of Saint Paul out to the Wisconsin border along the St. Croix River. The Mississippi River functions as an informal cultural dividing line. Minneapolis and its inner western suburbs retained the historic 612 code, while Saint Paul and its eastward expansions migrated entirely to 651.
The code spans three core counties and clips several adjacent rural communities. In Ramsey County, it encompasses urban neighborhoods like Summit Hill, Highland Park, and the state capitol complex. Expanding south into Dakota County, 651 reaches suburban economic centers such as Eagan Minnesota, home to significant logistics hubs, airline operations, and data centers. Moving east into Washington County, it covers the rapidly growing suburban hub of Woodbury MN, the historic river city of Stillwater, and waterfront towns along the scenic St. Croix valley.
Beyond the primary suburban perimeter, the 651 footprint extends south toward Red Wing in Goodhue County and stretches north into Forest Lake and rural portions of Chisago County. This vast territory blends state-level political institutions, health system headquarters like HealthPartners and Gillette Children's Specialty Healthcare, and residential communities supporting over 700,000 Minnesotans.
