Area code 320 is a telephone area code in the North American Numbering Plan for most of the central part of the U.S. state of Minnesota. The numbering plan area (NPA) excludes the Twin Cities metro region. The area code was created in 1996 in a split of area code 612.

History

In 1995, US West advised the North American Numbering Plan Administration (NANPA) that substantial demand for telephone numbers in Minneapolis/St. Paul required dividing numbering plan area 612 with the introduction of a new area code, 320, outside of the metro area.{{cite web |url=https://www.nanpa.com/sites/default/files/planning_letters/IL-95-09-007.pdf |title=Information Letter 95/09-007: NANP-Split of 612 (Minnesota) Numbering Plan Area (NPA) |publisher=NANPA/Bellcore |date=1995-09-15 |access-date=2025-05-05

320 was the fourth Minnesota area code, and the first new one in the state in 42 years.

In 1998, numbering plan area 612 was reduced to only Minneapolis and a few inner suburbs, when area code 651 was created.{{Cite web |last=Olson |first=Amy |title=Additional digits |url=https://mndaily.com/254557/uncategorized/additional-digits/ |date=1999-01-08 |access-date=2025-04-01 |website=The Minnesota Daily
