The Oregon Criminal History and Your Own Copy
Oregon is one of the states that lets anyone look up another person's statewide criminal history: an Open Record Request returns anyone's Oregon conviction record by name, and the subject is told who asked, for $10 a search, through the Oregon State Police. 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. The search is on the Oregon State Police site.
Arrest Records Kept Locally in Union County
The Union County Sheriff's Office and the agency that reports for La Grande keep the arrest records in Union County: the report and the booking record of each arrest stay with the agency that made it, separate from the court file and from the state repository.
The FBI's agency list also places these agencies in Union County: the Union County Liquor Commission (state agency); the Union County State Police (state police); each keeps the records of its own arrests.
Together, the two agencies in Union County with all twelve months of 2025 on file reported 576 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
The agencies and their counts, year by year, are in Union County arrest records.
The Crimes Behind the Records: Union County in 2025

Registration itself is done in person with the local agency where the registrant lives: the sheriff's office, or the city police in a city with its own department.
Asking an Agency in Union 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.
Under the Oregon Public Records Law a county office must answer a request within 15 business days where practicable, after acknowledging the request within 5, and it may charge the actual cost of making the record available.
