This is a private reference site, not a Dallas County government office. It cannot confirm whether a person is in custody, arrange release, post bond, change visitation, or retrieve an official booking record. Use the official office or court system that holds the record.
Where to Check First
Dallas County Sheriff's Office / Dallas County Jail
204 S. Poplar St.
Buffalo, MO 65622
Main phone: 417-345-2441
Non-emergency: 417-345-1999
Fax: 417-645-6238
Hours: Dallas County office hours were listed in the research as 8:00 a.m. to 4:30 p.m., Monday through Friday, excluding legal holidays. Because jail, dispatch, records, and visitor handling can use different schedules, call before visiting or sending a request.
Official sources identify the jail and sheriff's office at the same Buffalo address. Current public references identify Sheriff Darren Cheek, while an older sheriff administration page may still show a prior officeholder, so use the office contact details rather than relying on stale staff pages.
- For someone possibly held in the Dallas County Jail, start with jail inmate records and then call 417-345-2441 if the current-inmates page does not answer the question.
- For booking-photo questions, review jail roster mugshots and ask the sheriff's records custodian about available booking records under Missouri Sunshine Law.
- For charges filed after an arrest, use court records after a jail arrest and Missouri Case.net rather than the jail roster alone.
- For facility address, phone, and custody context, use the Dallas County Jail page.
- For a sentenced Missouri prisoner, use the Missouri Department of Corrections Offender Search instead of the county jail list.
- For federal sentenced custody or immigration detention, use the Federal Bureau of Prisons inmate locator or ICE ODLS.
