The 248 area code is a dialing number associated with Oakland County, which is located northwest of Detroit City and stands out as the second-most populous county of Michigan.
The 248 possesses a single overlay, the 947 area code that serves the same region. Both numbers surround not only Oakland County but also sections of Northville and Livonia, situated in Wayne County.
Located in the Eastern Daylight time zone, the 248 area code encloses 2 counties and more than 40 cities in Michigan, including Troy, Farmington Hills, Southfield, Rochester Hills, and Royal Oak.
The Bell System and AT&T put in service the 248 area code on October 5, 1997, as a split from the prefix 810 installed on December 1, 1993.
Initially, the 810 area code used to run in Oakland, Macomb, Genesee, Lapeer, St. Clair, and Sanilac counties. Since the activation of the dialing code 248, the 810 reduced its coverage radius to some portions of Oakland County, while the new prefix 248 surrounded almost the entire region.
Three years later of the introduction of the 248 area code, the 947 area code arrived at the county as an overlay. Approved in 2001 and activated on January 26, 2002, the 947 area code represented a long-term solution for the saturation conflict of Michigan’s telephone network.
The installation of the 947 area code to the telecommunication system made ten-digit dialing (area code+ 7 numbers) obligatory in the zone. Currently, there’s no project of a second overlay plan for the prefix 248.
