Find any 586- phone number in Michigan
The 586 area code is one of the area codes in Michigan that was introduced when the Michigan North American Numbering Plan (NANP) was divided into sections in June 2001. Previously, Michigan had been served by one numbering plan area (NPA) that covered the entire state. The new geographical area codes included 586, 616, 810, 906, and 989. 586 is located in the Detroit metro area and several of the surrounding counties, including St. Clair and Macomb.
The North American Numbering Plan (NANP) is a standardized system for assigning telephone numbers in the United States and Canada. In the NANP, all local phone numbers are made up of three parts: the area code, followed by the central office code and then the four-digit line number. All area codes within the NANP are three-digit codes that are used to specify a particular geographic region, like a city or a county. In Michigan, the area code 586 is used for the Detroit metropolitan area and its surrounding counties. This area code is used for both local and long-distance telephone calls and is necessary to complete the dialing process. Without an area code, calls cannot be made.
