How to find someone in the county jail
- Call the jail directly if the name does not appear; online rosters lag behind actual bookings.
- Search the county's official roster for the person's full legal name.
- If the person has already been sentenced, search the North Dakota Department of Corrections and Rehabilitation offender locator instead.
- Have their date of birth ready — it is the detail that separates people with common names.
- If the charge is federal, search the Bureau of Prisons system, which is separate from both.

The North Dakota state prison system
Sentenced prisoners in North Dakota are held by the North Dakota Department of Corrections and Rehabilitation, not by Cass County. A person stops appearing on the county roster once transferred.
How the Cass County jail system works
A county jail holds people from the moment of arrest until the case is resolved or a sentence is served. It is run by the county sheriff, funded by the county, and is entirely separate from the state prison system. Anyone sentenced to more than a short term will eventually be transferred out of it.
The sequence is normally booking, a first appearance, then either release on conditions or continued detention. Bail is decided at that appearance, and it can be revisited later if circumstances change.
What to ask when you call
A single call to the jail or the sheriff's office can answer most of what a family needs to know in the first days. Having the questions ready makes the call much shorter.
- The booking number and the facility housing unit.
- The next court date and the courtroom.
- The bail amount and the accepted payment method.
- Whether the person has already been assigned counsel.
- What identification you need to visit, and the visiting hours.
- Whether there are any restrictions on calls or visits in this case.

At the county jail, operated by the county. Cities within the county generally do not run their own long-term jails, so bookings are transferred to the county facility.
How do I find someone in Cass County jail?
Contact the Cass County sheriff's office directly. Where no public online roster is published, a phone call is the only reliable route.
What is the county seat of Cass County?
Cass County publishes its county seat, as does the U.S. Census Bureau.
How do I post bail in Cass County?
Bail is set by a judge under North Dakota law and is normally paid to the court or the county, not to the jail. Confirm the accepted payment method and the exact amount with the court before travelling.
Does Cass County publish mugshots?
Some sheriffs publish booking photographs and some do not. Where a roster is published, the sheriff's own site governs what is shown and for how long. We do not republish individual records.

That depends on the case. People awaiting trial are held until bail is posted or the case concludes; people serving a sentence are held for its duration, then transferred or released.
