Area Code 947 is a relatively recent addition to the North American Numbering Plan, officially implemented on June 6, 2021. It serves as an overlay for the existing 248 area code and primarily covers parts of Southeast Michigan, particularly the suburban regions surrounding Detroit. This development arose from the increasing demand for telephone numbers in a densely populated area.
Before the introduction of the 947 area code, the region relied solely on the 248 code, which had begun to exhaust its numbering resources due to the proliferation of mobile devices and new telecommunication services. The overlay design allows existing 248 users to retain their area code while providing new subscribers an additional range of numbers.
Unique to 947 is its conjunction with the 248 code, meaning that residents may need to dial ten digits for local calls, regardless of whether the numbers belong to the same area code. This dialing process represents a shift in telecommunication practices in the area, aligning with trends seen in many other urban regions across the United States.
With no geographic limitations, Area Code 947 encompasses a broad swath of communities, comprising cities like Troy, Farmington Hills, and parts of Oakland County. As part of the overlay plan, the code will continue to play a vital role in supporting the telecommunications infrastructure in one of the most dynamic regions of Michigan.

Dialing the area code 947 from another state in the United States is considered a long-distance call. Here’s how to make the call: First, dial the area code for 947. Each state, and sometimes specific cities within a state, has unique area codes. Then, enter the 7-digit phone number of the person or business you’re trying to reach. If you’re calling from a landline, check with your provider, as long-distance charges may apply. However, most mobile carriers in the U.S. offer nationwide calling without additional fees. Alternatively, you can use VoIP or internet-based calling apps, like Skype, Zoom, or WhatsApp, to bypass traditional long-distance charges. The number you want to reach should look like this: 1-(AreaCode)-111-2222.
