What is in this database?

The Minnesota CTU Database is a subset of the federal Geographic Names Information System (GNIS) database. It contains all Minnesota entries for cities, townships and Census-defined unorganized territories, both active and historical.

This system is integrated with the Office of Administrative Hearings Municipal Boundary Adjustment database. When a new city or township comes into existence, or when an existing city, township or unorganized territory becomes historical, that change is formally registered and reported to the U.S. Geological Survey for inclusion in the GNIS. This process results in the timely creation of a new updated CTU code.  The unique ID for each entry in the database complies with Minnesota’s state CTU standard and ANSI INCITS 446-2008.
