History of Area Code 278
Area code 278 is a geographic overlay for the area code 734 region. It was created as an overlay rather than as a geographic split, so new telephone customers can receive 278 numbers while customers with existing 734 numbers can keep their numbers.
Area code 734 was created in 1997 through a split of area code 313. The split left 313 concentrated around Detroit and placed Ann Arbor and other nearby communities in the new 734 area. The 278 overlay adds numbering capacity without changing the geographic boundaries of the 734 region.
