Area code 715 serves northern Wisconsin, including cities such as Eau Claire, Wausau, Superior, and Rhinelander. Established in 1947 as one of the original area codes, 715 covers a large and largely rural area known for its forests, lakes, and tourism industry. In 2010, area code 534 was added as an overlay to provide additional numbering capacity, and ten-digit dialing became mandatory. The region has a strong presence in logging, paper production, and outdoor recreation. 715 remains a long-standing and recognizable area code in Wisconsin, symbolizing the state’s northern charm and rugged character.
