Find any 608- phone number in Wisconsin
Wisconsin's area code system begins with 6 and is referred to as a NPA (Number Planning Area). When the original area code system was established in 1947, all of Wisconsin was assigned the area code 614. In 1954, the code 615 was split off from 614 and designated for Milwaukee and the surrounding area. In 1998, Wisconsin's area code system had grown to nine and a tenth area code was needed. At this time, the 608 area code was created and designated for the entire southern area of the state. It covers the cities and metropolitan areas around Madison and the WI River valley.
Within Wisconsin, the 608 area code is used for both wired and wireless devices. It also covers parts of the states of Illinois, Minnesota, and Iowa, which means it is a border state area code. This code is used for both landline and cellular devices as well. All of the 608 codes follow a unified numbering plan which designates a particular geographic region for certain numbers within the area code. The primary purpose of this system is to ensure the efficient use of the limited area code resources as well as helping to reduce the number of phone number changes for business and residential users.
