About Area Code 320
Area code 320 is a North American Numbering Plan (NANP) area code that has been in service since 1996. It is administered by NANPA on behalf of the FCC and serves the Minnesota region anchored on St. Cloud.
320 is currently a single-coverage geographic area code with no overlays. This means a 7-digit number in this area code is unique within its rate centers, though best-practice is always to dial the full 10-digit number when contacting a 320 line.
Mobile numbers in 320 are portable: a person who moved away from St. Cloud may still carry a 320 mobile number on their device. If you receive an unexpected call from a 320 number, run it through the reverse lookup tool above for the most accurate, free identification.
