History of Area Code 608

Area code 608 was established in 1947 as one of Wisconsin’s original North American area codes. In the original nationwide area code plan created by AT&T and the Bell System, Wisconsin had two area codes: 414 and 715. The 608 code served the southern and southwestern part of the state.

Area code 608 has not been split or overlaid. Wisconsin later added other area codes in different parts of the state, including 920 in 1997 and 262 in 1999, but 608 remained in place for its original region. Because 608 has no overlay, ten-digit dialing was not originally required across the whole area for local calls.
