FAQ · Michigan virtual numbers

Common questions about Michigan virtual phone numbers.

Quick answers on Michigan's 12 area codes, Detroit vs suburbs codes, ET routing, and porting your existing MI number.

Michigan has twelve active area codes: 231 (Northwest MI), 248 (Oakland County), 269 (Southwest MI), 313 (Detroit), 517 (Lansing/Central MI), 586 (Macomb County), 616 (Grand Rapids/West MI), 734 (Ann Arbor/Southeast MI), 810 (Flint/Eastern MI), 906 (Upper Peninsula), 947 (Oakland County overlay), and 989 (Saginaw/Northern MI). All twelve are on Ringflow.
313 is Detroit's historic area code, covering the city proper — Detroit, Hamtramck, Highland Park, and Dearborn. It's Michigan's most recognized code and carries strong association with the automotive industry and Detroit's cultural identity. For Oakland County suburbs north of Detroit, 248 or 947 are the right codes.
248 (and overlay 947) covers Oakland County — Troy, Pontiac, Royal Oak, Southfield, and the northern suburbs. 586 covers Macomb County to the northeast — Sterling Heights, Warren, and Clinton Township. 734 covers the western and southern suburbs — Ann Arbor, Dearborn, Livonia, and Ypsilanti. Each signals a distinct geographic community within Metro Detroit.
