History of Area Code 320

Area code 320 was created on March 17, 1996. It was split from area code 612 as Minnesota added new area codes to meet demand for more telephone numbers. The split reflected growth in telephone use across central and western Minnesota.

Area code 320 has remained a standalone geographic code since it was created. Public records from the North American Numbering Plan Administrator show it is not an overlay area code. Minnesota later introduced other new area codes in different parts of the state, but 320 itself continues to serve its original central Minnesota region.
