History & Cultural Notes
Rapid growth in and around Dane County drove the need for additional phone numbers in southwestern and south-central Wisconsin, culminating in the launch of area code 353 on September 15, 2023. It was introduced as an all-services overlay on the existing area code 608, meaning ten-digit dialing now applies throughout the combined numbering plan area rather than a new region being carved out.
Madison, the state capital and home to the University of Wisconsin-Madison, sits at the center of this overlay territory. The surrounding footprint extends to Janesville, Beloit, La Crosse, Wisconsin Dells, and Baraboo, linking the capital region to communities well to the west and south.
Government, higher education, and healthcare form the backbone of the local economy, complemented by agriculture and a growing technology sector. As with the 608 area it overlays, the 353 territory blends the administrative weight of the state capital with the agricultural character of the surrounding countryside, giving the region a mixed urban and rural identity.
