The area code splits in the Twin Cities are unusual because they split along municipal lines, rather than central office boundaries. This led to numerous 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.[1][2]
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. This area is in the Central Time Zone.
Despite the Twin Cities' rapid growth, 952 is nowhere near exhaustion. The April 2023 NANPA projections predict an exhaust date of 2119.[3]
Even with the split into four area codes, most of the Twin Cities region is still a single rate center.[4] The four Twin Cities area codes comprise one of the largest local calling areas in the United States; with a few exceptions, no long-distance charges are applied from one part of the Twin Cities to another. Portions of area codes 320 and 507 are local calls from the Twin Cities as well.
