Area code 320

Area code 320 is an area code for Minnesota. It entered service on March 17, 1996 as a split from area code 612. It covers cities such as St. Cloud, Alexandria, Willmar, Hutchinson, Brainerd, and Marshall. It was split by 651 in 1998, and then 763 and 952 in 2000. Ironically, 612 is the only area code 320 doesn't border despite the fact that it was first created from that area code.
