The North Dakota Criminal History and Your Own Copy
North Dakota is one of the states that lets anyone look up another person's statewide criminal history: name-based criminal history records are open to anyone who asks, through the North Dakota Bureau of Criminal Investigation. 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 request to the Bureau of Criminal Investigation. The state page SearchSystems verified for it is at attorneygeneral.nd.gov/public-safety/criminal-history-records.
