Map of area code 313 in Michigan.

Area code 313 is an area code within the North American Numbering Plan in the southeastern Michigan county of Wayne. It serves the city of Detroit, the enclave cities Hamtramck and Highland Park, as well as Dearborn, Dearborn Heights, Inkster, Melvindale, the Grosse Pointe communities, Lincoln Park, Redford, and Taylor north of Goddard Road.

History[edit]

The National Plan Area (NPA) 313 was created in 1947 as one of the original 86 codes. Originally, it included the entire southeastern quadrant of Michigan, including Metro Detroit, Flint, and the southern part of Michigan's "Thumb." With the rotary dialing technology in use at the time, AT&T took care to keep resource contention to a minimum for major cities, since they have the largest call volume. With this in mind, Detroit was assigned an area code with seven pulses, tied with Pittsburgh's 412 and Dallas-Fort Worth's 214 as the third-fastest that could be dialed under the original guidelines for area codes (the first digit could not be 0 or 1, the second digit had to be 0 or 1, and the third digit could not be the same as the second digit). This configuration remained in place for 46 years.

Because of the demand for new phone numbers, area code 810 was created for the northern suburbs, Flint, and the southern Thumb on December 1, 1993. On December 13, 1997, the 313 area was further divided, creating the 734 area out of Washtenaw County, Monroe County, and western and Downriver Wayne County.

Area code 679 has been reserved as a future overlay to the 313 area.[1][2] Relief planning is in progress[1] and 2014 estimates do not expected 313 to be exhausted until 2019.[3]

Use in Popular Culture[edit]

In the 2002 film 8 Mile, the character Jimmy "B-Rabbit" Smith, Jr., played by Eminem, mentions the 313 area code in a rap during the film's climax. The film is set in Detroit and Eminem is a Detroit native.
