320 Area Code: St. Cloud, Minnesota

Central Minnesota is served by the 320 area code, with St. Cloud as the primary city. St. Cloud sits along the Mississippi River in the rolling country of central Minnesota, organized around a downtown core, St. Cloud State University, and the surrounding granite-quarrying industry that has shaped the local economy alongside healthcare and a substantial cluster of manufacturing employment. The 320 footprint extends through Willmar, Litchfield, Alexandria, and the surrounding small cities and farming counties of central Minnesota.

Records linked to 320 numbers in the directory often include Bloomington, Brooklyn Park, Duluth, and Minneapolis — Minnesota cities outside the 320 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across Minnesota and addresses linked across multiple cities. The directory currently documents 282 distinct prefixes within 320 in detail, a working subset of the prefix population the code carries.

St. Cloud's median age sits well under the US figure, at the low thirties, a pattern shaped heavily by the substantial student population at St. Cloud State. Median household income runs below the national reading, home values come in below the US median, and population places St. Cloud as one of the larger Minnesota cities outside the Twin Cities metro — substantial enough to anchor a regional economy organized around the university, healthcare (the city is home to a large CentraCare hospital system), and the surrounding agricultural and manufacturing base.
