This is a private reference site, not a sheriff's office, jail, court, or records counter. We cannot confirm whether someone is in custody, release a detainee, post bond, schedule visitation, or pull an official booking record. Those requests must go to the government office that owns the record or controls the custody decision.
Where to Look First
For Hancock County jail and roster questions, start with the Hancock County Sheriff's Office / Jail Division. The county also states that Hancock inmates have been housed at Winnebago County Jail since 2018, so physical visitation, mail, and daily housing questions may require Winnebago confirmation after Hancock confirms the record path.

Use these pages to narrow the right source before calling or visiting:
- For someone who may be on the Hancock current roster PDF, use jail inmate records.
- For booking photo questions, use jail roster mugshots. The inspected Hancock roster did not display mugshots.
- For charges filed after booking, use court records after a jail arrest and Iowa Courts Online.
- For facility-specific rules, use the detention facility pages in the footer for Hancock County Jail / Jail Division and Winnebago County Jail.
- For a sentenced Iowa prisoner, use Iowa Department of Corrections Offender Search, not the county roster.
- For federal or immigration custody, use the BOP Inmate Locator or ICE Online Detainee Locator System. Hancock County, Iowa did not have a sheriff or police app located in the research sweep.
