What is ann arbor area codes?

The Ann Arbor area has two main area codes: 734 and 947.

The 734 area code was created in 1997 and covers the entirety of Washtenaw County, including Ann Arbor, Ypsilanti, and several surrounding communities. It is an overlay area code, meaning that new phone numbers can be assigned with either the 734 or 947 area code.

The 947 area code was created in 2015 as an overlay for the 248 and 586 area codes, which cover parts of Oakland, Macomb, and Wayne counties. The 947 area code covers the same geographic area as the 248 area code, and both codes are used interchangeably.

It is important to note that dialing both the area code and the seven-digit phone number is required for all calls within the Ann Arbor area. Additionally, some calls may require dialing a "1" before the area code and phone number, especially for long-distance or toll-free numbers.
