The Idaho Criminal History and Your Own Copy
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. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it.
To see your own record, the route is a fingerprint-based request to the Bureau of Criminal Identification. The state page SearchSystems verified for it is at isp.idaho.gov/bci/criminal-history.
Arrest Records Kept Locally in Custer County

Asking an Agency in Custer County for a Record
An arrest report, a booking record or a local criminal history letter comes from the agency that holds it, not from the court.
