Buy a Local Phone Number – Area Code 313 (Detroit, Michigan)

Assigned in 1947 as part of the original North American Numbering Plan, 313 once covered a wide slice of southeastern Michigan. Demand and suburban growth drove boundary changes, with major splits in 1993 (creating 810) and 1997 (creating 734). The code today anchors Detroit and adjacent Wayne County cities such as Dearborn, Hamtramck, and Highland Park. While regulators have considered overlay relief at various points, number conservation delayed implementation for years.

• Automotive and mobility manufacturing, including Ford in Dearborn, GM headquarters downtown, and major suppliers.
• Cross-border trade and logistics via the Ambassador Bridge, Detroit–Windsor Tunnel, rail links, and the port.
• Healthcare and higher education anchored by Henry Ford Health, Detroit Medical Center, and Wayne State University.
• Creative industries and tourism tied to Motown heritage, techno, museums, festivals, and professional sports.

Economic identity remains tied to large-scale manufacturing and engineering, complemented by logistics and cross-border trade with Canada. Healthcare networks and universities broaden the job base, and a deep music and labor history—Motown, techno, and the United Auto Workers—shapes civic culture. In everyday speech, locals sometimes use “the 313” as shorthand for the core city, reflecting a strong local identity that endures alongside ongoing reinvestment in neighborhoods and industrial corridors.
