Search Winnebago Criminal Cases by Case Number
Each criminal case in Illinois receives a unique number consisting of several parts. Understanding the format will help quickly find the required record.
Starting in 2023, Illinois courts transitioned to a standardized case numbering format as required by the state Supreme Court. A typical criminal case number looks like this:
- Year of filing — four digits (e.g., 2025)
- Case type code — letter designation of the category (CF — criminal felony, CM — misdemeanor, DT — driving offenses, TR — traffic)
- Sequential number — sequential number within the year and category
For example, the number 2025CF000123 indicates a felony criminal case filed in 2025 with sequential number 123. Older cases may have a different format — two-digit year and abbreviated codes. If you are unsure of the number, the court clerk will help clarify.
