About Michigan Area Codes
Michigan uses 12 area codes under the North American Numbering Plan (NANP), serving Ann Arbor, Battle Creek, Detroit, Flint, Grand Rapids, Jackson and 11 other communities. Each code follows the 3-digit format and covers a defined geographic region within the state.
Overlay Codes in Michigan
Michigan has adopted 1 overlay code(s): 947. An overlay assigns a new area code to the same geographic region as an existing code, so both codes serve the same area. When overlay codes are active, callers must dial all 10 digits (area code + number) even for local calls within the same region.
