Area codes 248 and 947 are area codess in the North American Numbering Plan (NANP) for Oakland County in the U.S. state of Michigan. The area codes also serve portions of Livonia and Northville, both located in Wayne County. The rest of Wayne County, including Detroit, located to the southeast, is serviced by area codes 313 and 734.

Area code 248 was created in 1997 in a split of area code 810. In 2000, area code 947 was assigned as an overlay area code for the area in relief of central office code exhaustion. In 2001, it was approved as an all-services overlay plan in the 248 numbering plan area, requiring ten-digit dialing after end of the permissive dialing period, which started on January 26, 2002.
