If the arrest was recent
Start with the county jail
Vermont is unusual: it runs a UNIFIED state corrections system with NO county-run jails.
A person who was just arrested and not released is held in a state-run Vermont Department of Corrections facility, not a county jail, so the SAME Vermont DOC public roster is the right tool for both a brand-new arrest and a sentenced inmate - you do not need to hunt across county sheriff rosters.
Vermont also participates in the national VINE system (Vermont VINE), a free way to check custody status and register for alerts by phone, email, or text (search at vinelink.com or use the VINELink app).
For a very recent booking or bail details, call Vermont DOC at 802-241-2442.
Vermont has NO county-run jails; the state Department of Corrections operates all correctional facilities and holds both pretrial detainees and sentenced inmates. Use the Vermont DOC public roster or Vermont VINE rather than looking for a county sheriff's jail roster, and call Vermont DOC (802-241-2442) for recent bookings and bail.
