Area code 906 covers Michigan’s Upper Peninsula, a vast, rugged region known for its natural beauty, low population density, and unique culture. Established in 1961, 906 is the only area code serving this part of the state and remains unchanged since its creation. It encompasses cities such as Marquette, Sault Ste. Marie, Escanaba, and Houghton. The region is famed for its dense forests, Great Lakes shoreline, and outdoor recreation opportunities including hiking, snowmobiling, and fishing. Economically, the Upper Peninsula relies on tourism, mining, forestry, and manufacturing, along with educational institutions like Northern Michigan University and Michigan Technological University. Due to its isolation and distinct identity, residents of the U.P. often refer to themselves as “Yoopers,” a term embraced with regional pride. The area code 906 has become synonymous with this sense of community and resilience. Despite modern telecom needs, the area’s low population density has preserved 906 as a standalone code without overlays. Businesses with a 906 number are easily recognized as local to the U.P., which is considered both a geographical and cultural departure from the rest of Michigan. For many, 906 is more than just digits—it’s a badge of belonging to a truly unique part of the Midwest.
