Statewide rules that apply at every WI DOC prison

These rules are set by WI DOC and apply at every unit. The full list — including all permitted and prohibited items and the approval process — is in Visiting in Wisconsin.

Dress code

No camouflage, transparent or revealing clothing, strapless or tube tops, spandex worn as pants, shorts or skirts shorter than fingertip length, gang-related or obscene items, or torn clothing; no watches or purses, and avoid underwire bras and metal jewelry that will not clear the metal detector.
Each institution enforces its own visiting dress code and may turn away a visitor who is dressed out of code, so confirm the specific facility's rules before traveling.

ID: Every visitor must be on the incarcerated person's approved visiting list before visiting — the person mails a DOC-21AA Visitor Questionnaire to the prospective visitor, who completes it and returns it to the institution. Visitors 16 and older show a valid government-issued photo ID at each visit.
What to bring: Bring only what the institution allows — phones, bags, and most personal items are not permitted in the visiting room. A visitor may bring up to $25 in cash or one debit/credit card for vending; money for the person's account is sent through Access Corrections, never handed over at a visit.
Scheduling: Wisconsin has no statewide online visit scheduler — visits are arranged with each institution (call the facility), and days and hours vary. Video visits are scheduled separately through ICSolutions. A newly committed person is processed at a reception center first — men at the Dodge Correctional Institution (Waupun), women at the Taycheedah Correctional Institution (Fond du Lac) — before transfer.
