Wisconsin registered agent rules, from the source (Department of Financial Institutions (DFI))

Every LLC must name a registered agent with an in-state street address.

A Wisconsin resident, or a business entity formed in Wisconsin or authorized there, whose business office is the registered office. The agent needs an email address and has to consent. (Wis. Stat. § 183.0115)

The address has to be an actual physical location with a street address in Wisconsin, not solely a P.O. box, mailbox service or answering service.
