Twin Falls County, Idaho, has about 97,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Twin Falls County Sheriff's Office and four city agencies. 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 Twin Falls 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.

Who Makes Arrests in Twin Falls County
The Twin Falls County Sheriff's Office is the county agency that reports arrests to the FBI for Twin Falls County. It reported 548 arrests for 2025.
Arrests inside four of the county's cities are reported to the FBI by an agency of the city's own, listed here with the Census population and what each reported:
- Twin Falls, 55,589 residents: 1,552 arrests reported for 2025.

- Buhl, 4,761 residents: 70 arrests reported for 2025.

A city on that list is reported separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.

Booking: Where People Arrested in Twin Falls County Are Held
The county jail is where a person arrested in Twin Falls County and kept in custody ends up, whichever agency made the arrest, though a city department may hold someone in its own cells first and a person cited and released at the scene is never booked. The jail's record of each person held, with the charges, is a public record of the arrest, and once the person is released or sentenced the record continues in the court file.
On an average day in 2019 the jail held about 300 people. Its rated capacity in 2019 was 196 beds, and it ran at 152 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Twin Falls County Sheriff's Office at roster.assurances.gov.gh/twin-falls-jail-roster-recent-bookings.html (page title: Twin Falls Jail Roster Recent Bookings), which answered when SearchSystems opened it on September 25, 2026.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
A sentence of more than a year is served in state prison; the Idaho Department of Correction lists its inmates at idoc.idaho.gov/content/prisons/resident-client-search.
How to Find Out About an Arrest in Twin Falls County
An arrest in Twin Falls County can be traced in three places, depending on where the case stands: the custody page of the Twin Falls County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Twin Falls County District Court, kept by the Clerk of the District Court, which shows whether charges were filed and the next court date; the Prosecuting Attorney, which decides whether an arrest becomes a charge (its page is at twinfallscounty.org/prosecuting_attorney, phone 208-736-4020).
The court records page SearchSystems verified for the county, at twinfallscounty.idahocourt.us/court-records.html (page title: Twin Falls County Court Records | Case Lookup), phone (208) 736-4025, belongs to a lower court, not to the Twin Falls County District Court.
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 Twin Falls County
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. 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.
- An arrest by the Twin Falls County Sheriff's Office: ask its records unit.
- An arrest in Twin Falls, Kimberly, Buhl or Filer: the records unit of the agency that reports for that city.
- A defendant who has been charged gets the report through the case: the Prosecuting Attorney, 208-736-4020, handles discovery for pending cases.
- The court file of a case that was filed: in the Twin Falls County District Court it is kept by the Clerk of the District Court. The court records page SearchSystems verified for the county, at twinfallscounty.idahocourt.us, phone (208) 736-4025, is a lower court's.
- Your own statewide record: a fingerprint-based request to the Bureau of Criminal Identification.
