If the arrest was recent
Start with the county jail
Rhode Island does not have county jails.
Anyone taken into custody after an arrest and not released - whether they are awaiting trial or already sentenced - is held by the Rhode Island Department of Corrections at the Adult Correctional Institutions (ACI) in Cranston; men are first processed through the Intake Service Center.
Because of this unified system, the same RIDOC Incarceration Search is the right tool for a just-arrested person, unlike states where you would look to a county sheriff's jail.
Rhode Island also participates in the national VINE system (Rhode Island VINE), a free way to check custody status and register for alerts (search at vinelink.com).
For a very recent booking or bail information, call RIDOC at (401) 462-3900.
Rhode Island has no county jails; all adult custody, pretrial and sentenced, is under RIDOC at the Adult Correctional Institutions in Cranston. Use the RIDOC Incarceration Search or Rhode Island VINE, and call RIDOC (401) 462-3900 for a recent booking or the bail amount.
