SIOUX FALLS, S.D. (KELO.com) — Some residents in Minnesota could be getting a new area code. The North American Numbering Plan Administrator filed a report with the Minnesota PUC saying 507 numbers will likely run out by 2025. One plan is to incorporate an additional area code for new customers. The other would be a geographical split of the current region. The 507 area code has been used in southern Minnesota since 1954.
