A 313 reads Detroit native
Restricted to Detroit proper and Wayne County, 313 carries city credibility — distinct from the 248/586/734 suburban splits that took everywhere else.

Michigan has 12 active area codes — 313, 679, 248 and 9 more. You can get a virtual Michigan phone number from any of these area codes through CallMama without a US address or SIM card.
Michigan received two original area codes in 1947: 313 (Detroit and southeast) and 616 (rest of the state). 517 was added in 1953 for Lansing and central Michigan; 906 followed in 1961 for the Upper Peninsula.
810 split from 313 in 1993 for Flint and the northern Detroit suburbs. In 1997, 248 carved off Oakland County (from 810), 734 took the western and downriver suburbs (from 313). 586 split off Macomb County in 2001.
密西根州西部和北部緊隨其後：西北地區從 1999 年的 616 人減少到 231 人，卡拉馬祖從 2002 年的 616 人減少到 269 人，中北部地區從 2001 年的 517 人減少到 989 人。疊層 947 (2002) 和 679 (2022) 分別涵蓋奧克蘭縣和底特律。
密西根州的 906 覆蓋了整個上半島，該地區在地理上被密西根湖與該州其他地區隔開，面積比新澤西州大，但居民人數不到 30 萬。它是密西西比河以東人口最稀少的單一區號地區之一。
