Start with Commissioners, linked from the government source used for this county. Check that page for current details before visiting or submitting a request.

Start with these official Minnesota resources: Locations; Disability parking certificates; Renew my tabs. Choose the page for the service you need, then check its office or online instructions before making a trip. These links cover state services; they do not establish that every transaction is available at a county office.

Use USPS ZIP Code Lookup for the mailing ZIP Code of a specific street address. Use the USPS location finder to search for nearby postal facilities and available services. An address lookup is more useful for mailing than assuming the entire county shares one ZIP Code.

The VA explains how to find and appoint an accredited representative for benefit claims. Contact a representative to confirm availability before appointing them. For education benefits, use the GI Bill application guidance. These are national VA services available to eligible local residents, rather than a listing of county offices.

Search USAJOBS for federal positions and the Apprenticeship Finder for apprenticeship opportunities, using location filters to narrow the results. USAGov job-training guidance points to training programs and state resources. Check each listing for current availability, eligibility and application instructions; a search result does not guarantee an opening in the county.

Named for Joseph N. Nicollet, the county held its first board meeting at Traverse des Sioux in June 1853. A later vote approved moving the courthouse to St. Peter, and construction of the present courthouse began in 1880 and finished the following year. The building subsequently underwent additions and repairs, including work after the 1998 tornado. These changes trace a civic history that links the county’s early river communities with the public institutions serving residents today.

Seven Mile Creek Park lies between North Mankato and St. Peter, with trails, footbridges, and Minnesota River access. Minnemishinona Falls offers a different stop at a scenic overlook on Judson Bottom Road. Check the county’s park information and respect posted boundaries at both locations. For town-based errands or exploration, the county directory also identifies Courtland, Nicollet, and Lafayette alongside St. Peter and North Mankato, making community names useful planning tools.

The 2020 Census geography figures record 448.592 square miles of land and 18.344 square miles of water in Nicollet County. The county’s total area includes both. These are geographic measurements for that Census vintage, not a measurement of current water levels or public recreation access.

In the Census Bureau’s 2025 estimate series, Nicollet County had an estimated 34,504 residents on July 1, 2020, and 34,273 on July 1, 2025. Over that interval, the estimated population decreased by 231 residents, or about 0.7%. Both figures come from the same estimate vintage, which revises earlier years for a consistent comparison.
