Union County, Illinois, has about 17,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Union County depends on where the incident happened: the Union County Sheriff's Office for the unincorporated county, the agency that reports for the city inside a city. This guide names each agency, where its records page is and what the Illinois Freedom of Information Act requires of it.
This guide covers which agency, the sheriff's reports, the cities' reports, how many reports, what the law requires and common questions.

Which Agency Holds a Report from Union County
A crime, incident or collision report belongs to the agency whose officer wrote it, and that agency releases it, not the court, the jail or the prosecutor.
In Union County that is the Union County Sheriff's Office for the unincorporated county and for any city that contracts with it for police service, and the agency that reports for a city where the city has one of its own.
Reports from the Union County Sheriff's Office
The Union County Sheriff's Office is the county agency; it had 6 violent and 42 property crimes reported for 2024 and reported 77 arrests for 2025.
Its reports come from its records unit. The office's page SearchSystems verified is its jail page, at ilsheriff.org/county/union (page title: Union County | Illinois Sheriffs' Association), a site that blocks automated checks (HTTP 403), so open it in a browser.
