Cook County Sheriff’s Office

What Cook County Sheriff’s Office does

Cook County Sheriff's Office is the principal law enforcement agency for Cook County, Illinois, a constitutionally mandated elected office operating since 1831 and currently led by Sheriff Tom Dart (in office since 2006). The organization runs the full county-level justice-services stack: Cook County Sheriff's Police patrol and investigation; the Cook County Department of Corrections, which houses more than 6,000 inmates across six corrections divisions in Chicago; Court Services covering six courthouse locations spanning Chicago and suburban districts (Skokie, Rolling Meadows, Maywood, Bridgeview, Markham); Cook County E-911 emergency dispatch; Community Corrections with electronic monitoring; and the Bureau of Training and Education alongside Community Engagement and Community Support Services programs. Public-facing technology includes an online E-File portal for civil process and order of protection filings, an Individual In Custody locator, in-custody mail and phone services, an attorney virtual visitation platform, in-person visitation systems, a Jail Data transparency dashboard, and a stolen-vehicle recovery program — all delivered through the cookcountysheriffil.gov web estate. The agency is a non-commercial government entity financed entirely through Cook County tax appropriations and public funding; it has no commercial revenue model, no parent company, no subsidiaries, and serves every resident and visitor within Cook County as its constituent base. Distribution combines in-person courthouse and corrections facilities with a growing layer of self-serve digital portals; awareness is driven through organic social channels (Facebook, X, Instagram, LinkedIn) rather than paid marketing.
