SearchSystems opened and checked the jail page of the Woodbury County Sheriff's Office at woodburycountyiowa.gov/sheriff/jail (page title: Jail Division | Sheriff | Woodbury County Government | Iowa), phone 712-279-6040, Monday - Friday, 8:00 a.m. - 4:30 p.m., which answered when SearchSystems opened it on September 24, 2026.
That page is the office's jail information page rather than a roster, so a search for a particular person goes through the office at 712-279-6040.
