Finding Someone in Custody in Delta County
A person kept in custody after an arrest in Delta County is held at the county jail, run by the Delta County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Delta County Sheriff's Office at deltacountymi.gov/sheriffs-office/correctional-facility (page title: Correctional Facility | Delta County), phone (906) 786-3633, Monday through Friday, 8AM-4PM, which answered when SearchSystems opened it on September 23, 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 (906) 786-3633.

The FBI's agency list also places one more agency in Delta County: the Delta County State Police (state police).
The largest arrest counts reported to the FBI were Escanaba's 366 for 2025, the Delta County Sheriff's Office's 137 for 2025 and Gladstone's 65 for 2025.
Together, the three agencies in Delta County with all twelve months of 2025 on file reported 568 arrests to the FBI that year. Those kept in custody were booked into the county jail; a person cited and released at the scene was not.

From the Jail to State Prison
A sentence of more than a year is served in state prison, not the jail; the Michigan Department of Corrections lists its inmates at mdocweb.state.mi.us/otis2.
