Finding Someone in Custody in Harris County
The county jail, run by the Harris County Sheriff's Office, holds everyone kept in custody after an arrest in Harris County, from every agency.
SearchSystems opened and checked the jail page of the Harris County Sheriff's Office at harriscountyso.org/JailInfo/Default (page title: Jail Information-Harris County Texas Sheriff's Office), phone 866-268-8959, which answered when SearchSystems opened it on September 23, 2026.
That page is the office's jail information page rather than a roster, so a search for a particular person goes through the office at 866-268-8959.

Who Books People Into the Harris County Jail
The Harris County Sheriff's Office and the agencies that report for Houston, Pasadena, Baytown, La Porte, Deer Park, Katy and 16 more cities make the arrests that end in a booking in Harris County.
The FBI's agency list also places these agencies in Harris County: the Galena Park Independent School District, the Harris County Constable's Precincts 1, 2, 3, 4, 5, 6, 7 and 8, the La Porte Fire Marshal's Office, the Houston Independent School District and 19 more (other agency); the University of Texas at Houston, the University of Houston's Central and Downtown Campuses, Texas Southern University, San Jacinto College's Central Campus and six more (campus police).
The Waller Police Department, the Stafford Police Department, the Missouri City Police Department and three more are each listed by the FBI across several counties including Harris County, so their arrests are not broken out for Harris County here.
From the Jail to State Prison
A sentence of more than a year is served in state prison, not the jail; the Texas Department of Criminal Justice lists its inmates at inmate.tdcj.texas.gov/InmateSearch/start.
