Michigan’s 586 Area Code: Coverage Map & Phone Carrier Info

Area codes are a vital part of the North American Numbering Plan (NANPA). They’re essential for routing phone calls to the correct geographic region within the larger phone network. Think of them as digital signposts, guiding your call where it needs to go.

This article focuses on area code 586 and its importance within the state of Michigan. So, what area code is 586 in Michigan? It’s the area code that covers a large portion of Macomb County, MI.

We’ll dive into the specifics, including its location and time zone, the history of its creation, the cities and counties it covers geographically, and information about the major telephone carriers operating within the 586 area code.

Where is area code 586, and what time is it there?

Area code 586 is located in southeastern Michigan, in the Eastern Time Zone. It serves communities like Warren, Sterling Heights, and St. Clair Shores, all of which are in Macomb County.

Because it’s in the Eastern Time Zone, area code 586 follows Eastern Standard Time (EST) during the winter and Eastern Daylight Time (EDT) during the summer. EST is five hours behind Greenwich Mean Time (GMT -05:00), and EDT is four hours behind Greenwich Mean Time (GMT -04:00).

So, if it’s noon in London, it’s probably 7 a.m. in the 586 area code.

How did area code 586 come to be?

Area code 586 is relatively new. It was introduced on September 22, 2001, making it the 306th area code in the North American Numbering Plan Administration (NANPA) system.

So, why did they need a new area code in southeastern Michigan? Well, the existing area code, 810, was running out of available phone numbers. The demand for new numbers was simply too high, necessitating the creation of 586.

Area code 586 was actually the tenth area code introduced in Michigan. (Michigan now has a total of 12.)

Interestingly, the original plan wasn’t to create a completely new area code. Instead, the idea was to implement an “overlay,” where both 810 and 586 would serve the same geographic area. But eventually, they decided on a “geographic split,” dividing the region and assigning 586 to a specific part of it.
