Area code 320, Telephone prefix in central Minnesota, US.
Area code 320 covers central Minnesota and connects cities like St. Cloud, Willmar, and Brainerd within its service territory. The region spans multiple counties with a mix of urban centers and rural communities.
The area code was established in 1996 when it split from the older 612 code, marking the first new telephone prefix in Minnesota after more than 40 years. This change became necessary as the region's population grew and more phone numbers were needed.
The region connected by area code 320 includes multiple counties with distinct local communities, maintaining strong connections through telecommunications networks.
Calls within the 320 area require only seven digits, but calls from outside the region need the complete ten-digit number. Visitors or those contacting people in this region should keep this distinction in mind to avoid connection issues.
The service area borders every other Minnesota area code except 612, from which it originated, creating a distinctive geographic pattern. This position places it as a connecting point between different parts of the state.
