MADISON, Wis. – Life in southwest Wisconsin soon will have a new layer of complexity. The state Public Service Commission authorized a new area code for the 608 area. The new code, 353, will be used for new and additional lines. This is effective September 15. The Commission said the 21-county 608 zone was running out of available digits. The Commission said there will be no new customer charges between the old 608 and new 353 numbers.
