Find any 507- phone number in Minnesota
The 507 area code is one of the original 86 North American Numbering Plan (NANP) area codes from 1947. The NANP is a system of numbering plan areas (NPAs) that have been assigned to countries in the North American region, most notably the United States, Canada and its territories, and the Caribbean. Area codes designate geographic regions and are required for placing calls and routing phone numbers.
The 507 area code covers most of Southern Minnesota, including the cities of Mankato, Rochester, Winona, Albert Lea and Austin. The area code was split in 1996 when the 612 area code was added to the Twin Cities. Since then, population growth in the region has caused the need for new area codes within the 507 area code, including the 320 area code which was implemented in 2000.
