Minnesota ZIP Codes

Minnesota is home to 798 ZIP codes spanning the full breadth of the state, from the bustling Twin Cities metro to remote communities along the Canadian border and the shores of Lake Superior. These codes are organized across 87 counties and 673 cities, using prefixes that range from 550 to 567 and reflect both population density and geography. Hennepin County, anchored by Minneapolis, holds the most ZIP codes of any county in the state with 74, while much of greater Minnesota is served by the 56x prefix series across wide, lightly populated landscapes. Whether you're mailing a package to a Saint Paul neighborhood or a small Iron Range town, Minnesota's postal system is built to reach every corner of this geographically diverse state.

Minnesota ZIP codes fall within two main prefix ranges: the 550–559 range primarily covers the Twin Cities metro area and central Minnesota, while the 560–567 range extends across greater Minnesota, including the western prairies and the northern regions bordering Canada. The 551 prefix is notably concentrated in Saint Paul and its immediate suburbs, while prefixes like 566 and 567 reach into the remote lake country and Iron Range of northern Minnesota. This geographic split in prefixes broadly reflects the population divide between the densely settled metro corridor and the vast, sparsely populated outstate regions.

Hennepin County leads all Minnesota counties with 74 ZIP codes, a reflection of its status as the state's most populous county and home to Minneapolis, dozens of inner-ring suburbs, and a dense urban core that requires fine-grained postal divisions to handle the volume of mail.

• Minnesota's ZIP codes span a range of over 1,700 numbers (55001 to 56763), yet only 798 of those possible values are actually assigned, highlighting how the postal system leaves gaps for future growth or administrative organization.
• The Twin Cities metro area is served by the 550 and 551 prefixes, making Minneapolis and Saint Paul two of the few major U.S. metro areas where two large cities share neighboring but distinct prefix groups rather than a single unified one.
• Minnesota's northernmost ZIP codes, found in communities like Baudette and Roseau near the Canadian border, are among the most geographically isolated postal areas in the contiguous United States, sometimes serving communities accessible only by a handful of roads.
