Madison County, Idaho, has about 56,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Madison County Sheriff's Office and one city agency. An arrest leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the Prosecuting Attorney files charges, a case in the Madison County District Court. This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies, cities and common questions.

How Many Arrests Each Agency Reports in Madison County
Each agency reports its arrests to the FBI by month, and the FBI publishes them on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- Rexburg: 421 for 2025, 457 for 2024, 436 for 2023, 307 for 2022, 414 for 2021 and 295 for 2020.

Together, the two agencies with all twelve months of 2025 on file reported 569 arrests that year. The same agencies with both 2025 and 2024 complete reported 569 in 2025 against 582 in 2024, down 2.2 percent.
Through July 2026, the two agencies with every month so far on file reported 149 arrests, against 378 in the same months of 2025.
Booking: Where People Arrested in Madison County Are Held
A person kept in custody after an arrest in Madison County is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2019 the jail held about 50 people. Its rated capacity in 2019 was 81 beds, and it ran at 62 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Madison County
For Madison County the place to look is the case index of the Madison County District Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at madisoncountyid.gov/departments/courts).
Statewide, iCourt Portal is the Idaho courts' free statewide case search.
Idaho is one of the states that lets anyone look up another person's statewide criminal history: name-based conviction checks are open to the public, through the Idaho State Police Bureau of Criminal Identification. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Madison County
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the Idaho Public Records Act the agency must answer within 3 working days, or 10 when more time is needed, and it may charge copying after the first 100 pages and labor after the first two hours.
