Williamson County Jail Overview

Williamson County Jail is operated by the Williamson County Sheriff's Office Corrections Bureau. The jail is the local booking and custody facility for Williamson County, not a state prison and not an immigration detention center. Its population includes pretrial detainees, local misdemeanants, county jail sentence commitments, parole violators, state jail felony cases awaiting disposition or transfer, and other local agency holds. Those categories matter because a person may leave the county jail record system after release, transfer to TDCJ, or movement to another agency.

The Corrections Bureau says the jail staffs sworn officers and civilian personnel, provides security at all hours, books and releases inmates, maintains inmate property and money, processes bonds, coordinates court movement, and handles visitation, mail, money, and commissary services. The public-facing access path is the county-linked jail lookup, with the jail information line and public information request process as fallbacks.

The official Corrections Bureau page is the source image for this jail page.

The county corrections page is useful because it ties the jail's capacity, visitation vendor, mail vendor, money deposit channels, commissary link, and jail information phone to one official source.

Williamson County Jail Capacity

The Williamson County Corrections Bureau describes the jail as a direct-supervision facility with bed space for 1,104 inmates after an expansion that opened in late 2003. The same capacity appears in the Texas Commission on Jail Standards June 2026 population workbook. TCJS reported a total Williamson County jail population of 649 on June 1, 2026, while the county's own corrections page gives an approximate daily population of about 600 inmates. Those figures place the jail well below rated capacity on that date, but daily custody can shift with arrests, releases, court orders, bonds, and transfers.

Williamson County Jail Lookup

The official online route starts at the county Court Case Lookup page, which links to the Jail Lookup. That portal is the right tool for current Williamson County Jail custody. It is not the same as the criminal case portal for filed charges, the TDCJ locator for sentenced state prisoners, or ICE ODLS for immigration custody. Because the portal uses a session-based PublicAccess system, a browser may need to load a disclaimer or session page before search fields appear.

1. Open the county Court Case Lookup page and choose Jail Lookup for jail custody.
2. Search by full legal name, booking number, or another exact identifier when available.
3. Try spelling variants if the first search fails, especially with hyphenated names or suffixes.
4. Confirm the result is a Williamson County Jail custody record, not a criminal case docket.
5. Call 512-943-1365 if a recent arrest, transfer, or release is not clear online.

Williamson County Jail Contact

Use the jail information line for live custody questions, release timing, bond routing, visitation scheduling problems, and mail or money procedure questions. The sheriff's administrative office is nearby, but the jail phone is the more precise route for jail custody. Public information requests should be sent to the office that maintains the record, with enough detail to identify the person, date, booking number, arresting agency, and record type.

Williamson County Jail Visits

Williamson County Jail visitation uses Securus Technologies. Visitors must register and schedule through the Securus app or website, must be on the inmate's approved visitor list, and must present a valid driver's license or state or federal ID. The county says each inmate is allowed two free 20-minute visits per week. Visitors must be at least 18 unless accompanied by a parent or legal guardian.

Note: Confirm the visit slot and approval status before traveling because booking, housing, discipline, court movement, or release can change access.

Williamson County Jail Mail

Personal mail does not go to the Georgetown street address. The county directs inmate personal mail through NCIC Inmate Communications in Longview, using the inmate's full name and identifier with the jail name. Money deposits use CorrectPay and the jail lobby kiosk, while commissary ordering is through Tiger Commissary. Posted vendor fees, card charges, product availability, and cutoff times should be confirmed at the time of use because the research did not locate a full fee schedule.

Williamson County Jail Booking

Booking starts after an arrest by a sheriff's deputy, municipal police officer, state trooper, or another agency. Intake can include identity confirmation, arrest paperwork, charge and hold entry, property inventory, fingerprints, a booking photograph when required, medical and mental-health screening, and classification. The jail also manages property and money, bonds, court coordination, and release processing. A person may not appear online right away because spelling, identity checks, medical screening, magistration, or system entry can take time.

Texas Code of Criminal Procedure Article 15.17 governs the early magistrate warning and first appearance. That step can affect bond and court routing. Booking charges are not the same as final filed charges, and a court record may later show amended, reduced, dismissed, indicted, or convicted charges. For filed case details after a jail arrest, use the criminal case portal rather than treating the jail roster as the final court record.

Williamson County Jail Records

If the online jail lookup does not show the needed record, the county public information route requires a written request to the office that maintains the record. The County Attorney public information page says requests should describe the records sought, identify the office or department that maintains them, and include contact details so staff can ask for clarification. The county lists hand delivery, mail, and email as approved channels for that office.

Texas Government Code Chapter 552 controls public information requests, while section 552.108 can protect some law-enforcement and prosecution material. Subsection 552.108(c) treats basic information about an arrested person, an arrest, or a crime differently from full investigative material. Juvenile records, sealed cases, expunction orders, medical facts, security details, and active prosecution records may require redaction or withholding.
