How to find someone in the county jail
- Search the county's official roster for the person's full legal name.
- If the person has already been sentenced, search the Colorado Department of Corrections 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.
- Call the jail directly if the name does not appear; online rosters lag behind actual bookings.

The Colorado state prison system
Sentenced prisoners in Colorado are held by the Colorado Department of Corrections, not by Arapahoe County. A person stops appearing on the county roster once transferred.
How the Arapahoe 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.
