313 Area Code: Detroit's Number for the Motor City

313 is one of the original 1947 area codes, and unlike many major cities, Detroit has kept the same code for its urban core for over 75 years — a badge of identity through the city's industrial rise, decline, and modern comeback.

History & Coverage

313 originally covered a huge portion of Southeast Michigan before splitting off 810, 248, and 734 to serve the growing suburbs. Today it's concentrated on the city of Detroit itself.

Why Businesses Choose 313

• Automotive industry heritage: as the historic home of Ford, GM, and Chrysler, 313 carries deep credibility for manufacturing and automotive-adjacent businesses
• Downtown revitalization momentum: Detroit's ongoing comeback, driven by investment in the Riverfront and Corktown districts, has renewed interest in 313 as a symbol of the city's resurgence
• Music and cultural legacy: Motown's birthplace, 313 carries strong cultural cachet for music, media, and creative businesses

Key Industries & Neighborhoods

Downtown Detroit and the Renaissance Center anchor corporate headquarters, while Corktown and Midtown add a growing tech, creative, and hospitality scene amid the city's redevelopment.
