Additional Area Code Will Soon be Used in Southern Wisconsin

The Public Service Commission of Wisconsin has announced the creation of a new, additional area code to overlay the 608 area code.  The 608 area code is expected to run out of assignable prefixes in the first quarter of 2024. The new 353 area code will be used to provide telephone numbers to new customers. All current customers will retain their existing telephone numbers and will continue to dial and receive calls without change.  The new 353 area code will be in service by late 2023.  An area code overlay adds a second area code to the geographic region served by the existing area code. Therefore, multiple area codes co-exist within the same geographic region. Once the 608 area code runs out of assignable prefixes, new customers in south central and southwestern Wisconsin may be assigned telephone numbers in the new 353 area code. Customers will continue to dial the three-digit area code for all calls to and from telephone numbers with the 608 and 353 area codes. The price of a call will not change due to the overlay.
