History

Macomb County was originally served by Detroit's area code 313, one of the original 86 area codes in the North American Numbering Plan. In 1993, area code 810 was split from 313; the service area of 810 initially included all of the former 313 outside of Monroe, Wayne, and Washtenaw counties.

In 1997, Oakland County, bordering Macomb County to the west, was split from area code 810 as area code 248. Area code 586 was first proposed as an overlay for the 810 territory, to be implemented in 2000.[1] However, overlays were still a new concept at this time, and met with some resistance due to the need for ten-digit dialing. In the face of intense opposition to the overlay proposal, 586 was instead implemented as a split, with most of Macomb County getting the new area code. The area code was introduced on September 22, 2001. Permissive dialing of 810 continued until March 23, 2002.[2]
