MADISON, Wis. (AP) — A new telephone area code for southern Wisconsin is set to go into effect next month. The Wisconsin State Journal reports that the 353 area code will overlay the 608 area code region beginning Sept. 15. Customers requesting new or additional lines in the region will get the new area code. People with an existing 608 area code will keep that number. State utility regulators say the 608 area code is expected to run out of assignable prefixes by the first quarter of 2024. Prefixes are the first three numbers that follow the area code. Wisconsin currently has six area codes: 262, 414, 608. 715, 534 and 920.
