The area code splits in the Twin Cities are unusual because they split along municipal, rather than central office, boundaries. This led to a sizeable number of exchanges being divided between two area codes. One central office, the Penn Avenue office in Minneapolis, had its geographical territory divided into area code 612 for portions in Minneapolis; 763 for portions in Golden Valley; and 952 for portions in St. Louis Park. Competitive local exchange carriers serving large portions of the metro area also ended up serving three area codes with the same prefixes.12
952 is bordered on the north and northeast by 763 and 612 respectively, on the east by area code 651, and by area code 507 to the south.
