Ada County inmate search: who is in the Ada County jail. One name search reaches the Ada County Jail roster and every other record type below.
Ada County is home to about 524,673 people (US Census Bureau, 2023 estimate), up 6.0% since the 2020 census: 27% of Idaho’s residents, the most populous of its 44 counties. People arrested here are booked into the Ada County Jail, and Ada County publishes who is held there on its own roster at apps.adacounty.id.gov. A search here checks that roster together with the records below, so one search answers whether a person is in the Ada County jail, in a Idaho state prison or in federal custody.

Ada County jail roster: what a booking record shows.
A booking record is made when someone is taken into custody at the Ada County Jail. It is an arrest-stage record: it says the person was booked on a date, on the charges written down at booking, and whether bond was set. It never says the person was convicted.
Most official rosters list only the people held now, so an entry usually comes down after release. Ada County’s roster at apps.adacounty.id.gov is the place to confirm current custody.

Ada County arrest records: arrest, charge and outcome. Three records, three places.
Booking at the Ada County Jail
Shows that someone was arrested in Ada County and what they were booked on. Searchable here through the Ada County Jail roster.
Filed in the District Court
Prosecutors decide what to charge. A felony goes to the District Court; a misdemeanor to the Magistrate Division of the District Court. The charge filed can differ from the charge at booking.
Disposition in the court file
Conviction, dismissal or acquittal is in the court record, kept by the Clerk of the District Court. With no statewide court source in the search, confirm it with the clerk.
An arrest record alone never proves a crime. Read the guide to arrest records for how bookings, charges and dispositions differ, and why a dismissed charge can still appear.
Ada County arrest records by city. Boise, Meridian and Eagle and 3 more.
Ada County has 6 cities and towns of 10,000 people or more. Someone arrested by a city police department in Boise or Meridian is usually booked into the Ada County Jail, unless the city runs a jail of its own, so a search of the Ada County Jail roster covers arrests across the county.
City populations: US Census Bureau, 2023 estimates. Linked cities have a sex offender page with a map and a search by address.
Ada County court records: finding a case and its outcome.
In Idaho, felony cases from Ada County are heard in the District Court, and misdemeanors in the Magistrate Division of the District Court. The Clerk of the District Court keeps the case files, which is where a disposition, a sentence and later sealing or expungement orders are recorded.
Idaho court records are not in our search, so a Ada County case outcome has to be confirmed with the clerk.
Finding a Ada County case yourself
- Get the full name and a date of birth; a case number, if you have one, is faster still.
- Search Idaho iCourt: icourt.idaho.gov.
- For a certified copy of a judgment, ask the Clerk of the District Court; certified copies usually carry a small fee.
Ada County warrant search: Idaho warrant lookup.
Idaho publishes a statewide warrant system, and a name search here includes it, so a warrant entered there for someone in Ada County shows with the person’s other records. Not every local warrant reaches a published list. A search that finds nothing is not proof that no warrant exists; to be certain, ask the Ada County sheriff’s office or the Clerk of the District Court.
Ada County mugshots: where booking photos are published.
A booking photo is taken at the Ada County Jail when someone is booked. Where Ada County publishes it, it appears on the official roster at apps.adacounty.id.gov, usually only while the person is held.
OffenderSearch does not show or sell booking photos, and never charges to remove anything. A photo on a commercial mugshot site is not a conviction, and several states restrict sites that charge to take one down.
