History of 586 Area Code
Area code 586 was assigned on July 8, 1999, and implemented on September 22, 2001. It was Michigan’s 10th and one of the 26 area codes introduced that year.
Before 1993, Macomb County was initially served by Detroit’s 313 area code. In that year, the 810 area code was split from 313. Again, after four years, Oakland County was split from 810 to form area code 248. Like 248, 586 was also brought to relieve pressure on 810 phone numbers.

How Does a 586 Phone Number Work for Your Business?
A 586 area code phone number operates under the North American Numbering Plan (NANP) and provides a recognizable local presence for businesses and organizations across southeastern Michigan, particularly in Macomb County and the northeastern Detroit suburbs. This allows companies to connect with their customers through mobile, landline, and VoIP services while reinforcing a regional identity within the Detroit metro area.
As of 2026, the 586 area code follows 10‑digit dialing due to the nationwide implementation of 988 as the crisis line. Callers must dial the area code plus the seven-digit number for all local calls. While long-distance calls within the U.S. must use 1 + 586 + the seven-digit number, additionally the international callers reach the number using +1 586 XXXXXXX from mobile phones.
Businesses in the region can obtain 586 area code numbers through virtual phone number providers like calilio or any other traditional providers. These numbers help your business with efficient call management, direct customer communication, and a consistent local presence without needing a physical office in every community.
