Area code 534 is an overlay for area code 715 in northern Wisconsin, covering cities such as Eau Claire, Wausau, and Ashland. Introduced in 2010, it was created to address the demand for new numbers in the sparsely populated but geographically expansive region. With ten-digit dialing now required, 534 is commonly used for mobile phones and new lines in rural communities. The area is known for outdoor tourism, natural beauty, and small-town culture. 534 supports the growing needs of northern Wisconsin without disrupting the long-standing 715 system.
