Area code 586


Area code 586 is the telephone area code serving much of Macomb County, Michigan, introduced in 2001 as a split from area code 810. Its territory was originally part of area code 313.

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 on top of 810, to be implemented in 2000. Opposition to the overlay proposal was intense, and 586 was instead implemented as a split. The area code was introduced on September 22nd, 2001, with permissive dialing ending on March 23rd, 2002.
