History of Area Code 679
Area code 679 was established in the 2020s as an overlay for area code 313. The 679 code entered service on March 13, 2024. An overlay adds a new area code across an existing service area, so 679 did not replace 313 or divide the Detroit region into separate sections.
Area code 313 was one of the original North American Numbering Plan area codes created in 1947. Population growth and rising demand for telephone numbers led to regional changes, including the creation of area code 810 from 313 in 1993 and area code 734 from 313 in 1997. Area code 679 added numbering capacity without creating another geographic split.
