Union County Detention Overview
The official Union County Detention Center page identifies the jail as the county detention campus at 1657 Jonesville Highway, Union, SC 29379. The published inmate information phone line is (864) 429-2818. The detention page names Niel McKeown as Director, while the county staff directory also lists Neil/Niel McKeown as Detention Center Director with an administrative staff-directory number. For a custody question, visitor question, or roster question, the detention-center number is the public route.
Union County describes the campus as a combined Pretrial and Work Camp operation. It holds county and city detainees awaiting court action, people serving short sentences from Summary Court or General Sessions, and people serving Family Court sentences. That mix matters when reading the jail roster because a row may show a person held for the Sheriff's Office, Union Public Safety Department, Jonesville Police Department, SCDC, probation and parole, ICE, US Marshals, Family Court, or another agency. The broader county custody picture is summarized on the Union County inmate population page.
The county's detention-center screenshot below comes from the same source used for the facility facts. The Union County Detention Center source page is the page that publishes the inmate portal button, visitation directions, CIDNET information, commissary route, and mail rules.
The image supports the custody and service details used here, but a live roster check should still be made through the inmate portal because custody data can change quickly.
Union County Detention Population
Official Union County material gives a useful population picture without publishing a rated bed count. The Pretrial and Work Camp Divisions employ 32 officers and supervise an average population of 100 county and city detainees. Those detainees include pretrial inmates, short county or city sentences of 90 days or less, and Family Court sentences. The county also publishes a separate work-camp figure for the Prison Work Facility, which houses up to 20 State Inmate Workers.
Rated bed capacity, annual bookings, average length of stay, and formal demographic tables were not located in official county sources. The public portal supports race, sex, age, held-for agency, arrest date, and in-custody date filters, so the roster is useful for current custody review. It should not be treated as an annual jail report.
Union County Detention Lookup
The correct online lookup for Union County Detention Center is the Union County inmate portal. The portal is free and is linked by the county detention-center page and sheriff page. It is built for current and recent custody, not a full historical archive. Its public configuration shows filters for name, race, sex, in-custody date, arrest date, and held-for agency. The in-custody date filter is limited to dates within the last 7 days.
- Open the Union County inmate portal and leave the in-custody date at the current date for a person believed to be in jail now.
- Search by last name or full name. Add race, sex, arrest date, or held-for agency only if the name returns too many rows.
- Read the roster row for mugshot, name, race, sex, age, arrest date, held-for agency, and hold reasons.
- If the person does not appear, call (864) 429-2818 or check the SCDC incarcerated-inmate search for state custody after sentencing.
The row's hold-reasons field is often the most detailed public field. It can show warrant text, statute or code, charge wording, bond status, bond type, bond amount, judge, and outside holds. A roster charge is an arrest or booking allegation. It is not the same as a conviction or the final charge filed in court. For a field-by-field roster walkthrough, use the Union County jail inmate records page.
| Lookup Channel | Use It For | Important Limit |
|---|---|---|
| Union County inmate portal | Current or recent county jail custody | In-custody date filter reaches back 7 days |
| Detention Center phone | Recent arrests, roster questions, visitor status | Call (864) 429-2818 |
| SCDC locator | Sentenced state prisoners after transfer | Not for county pretrial bond data |
| VINELink South Carolina | Custody and release notifications | Notification tool, not the official county roster |
Union County Detention Contact
Use the jail contact route for custody confirmation, visit questions, and inmate information. Use the Sheriff's Administrative Services route for incident reports, local background checks, and broader records questions. The detention-center page does not publish lobby hours or a separate jail-records web form, so phone confirmation is the safest step before travel.

Union County Detention Visitation
Union County separates state inmate visitation from county sentenced and pretrial visitation. State inmate visitation is listed for Saturday from 12 p.m. to 3 p.m. County sentenced inmates and pretrial inmates must use video visitation through CIDNET. The county says visits are not scheduled at the Detention Center, and families may use remote or onsite video visits through the vendor.
| Population | Visit Type | Schedule or Setup | Contact |
|---|---|---|---|
| State inmates and state inmate workers | In-person state inmate visitation | Saturday, 12 p.m.-3 p.m. | Confirm with (864) 429-2818 |
| County sentenced inmates | Video visitation | Remote or onsite video, scheduled through CIDNET | customer.cidnet.net or 888-984-1903 |
| Pretrial inmates | Video visitation | Remote or onsite video, scheduled through CIDNET | customer.cidnet.net or 888-984-1903 |
| Attorney visits | Not posted in official sources | Call before arranging legal visits | (864) 429-2818 |
A victim or co-defendant in the crime charged may not visit or send mail to that inmate. Jail administration may cancel or shorten visits when safety or security requires it. Dress code, visit length, child-visitor rules, and holiday schedules were not located in the official source set.
Union County Detention Mail
Incoming mail is inspected before delivery. The county says mail to and from an inmate is not limited unless clear and convincing evidence justifies a limit. Outgoing mail is collected and incoming mail is delivered in a timely manner. Indigent inmates receive postage, envelopes, and writing materials for two personal letters per week, with similar access for communication with lawyers and court officials.
| Service | Provider or Rule | How to Use It |
|---|---|---|
| Phone accounts | CIDNET | Create an account at customer.cidnet.net or call 888-984-1903 |
| Video visits | CIDNET | Schedule through the vendor, not at the jail desk |
| Commissary orders | McDaniel's Supply / JailPackStore | Use jailpackstore.com or call 800-822-9388 |
| Account deposits | McDaniel's Supply / JailPackStore | Use the same JailPackStore route; county fee table not posted |
The official sources did not locate a postcard-only rule, booking-number envelope format, publication list, photo limit, kiosk detail, or money-order policy. Confirm the current mail format and deposit rules with the Detention Center or vendor before sending funds or items.
Union County Detention Booking
Booking at Union County Detention Center can follow an arrest by the Sheriff's Office, Union Public Safety Department, Jonesville Police Department, South Carolina Highway Patrol, SLED, or another agency. Intake normally includes identification, property handling, security search, fingerprints, booking photo, medical or safety screening, and entry of charges or holds. The portal confirms public booking photos for many current inmates and shows age instead of full date of birth.
After booking, bond and first appearance move through Magistrate Court. The Magistrate Court page says bail bond hearings are held two times daily. A person may still remain in custody after local bond if the roster shows a hold for SCDC, probation and parole, ICE, US Marshals, another county, or another agency. That is why the held-for agency and hold-reasons fields must be read together.
Union County Detention Programs
The most specific local program detail is the work-camp operation tied to the detention campus. Supervised inmates prepare meals in the Detention Center kitchen for Prison Work Facility inmates and pretrial detainees. Work details also support county buildings, the animal shelter, and the maintenance shop. Prison Work Camp inmates help with Union County Palmetto Pride litter pickup and Code Enforcement property cleanups.
Medical, mental-health, grievance, GED, vocational, religious-service, tablet, and substance-abuse program details were not located in official sources. The portal metadata does list observation and medical-observation cell-block labels, but that should not be read as a published treatment program.
Note: Confirm custody status, visitation category, and vendor setup with the Detention Center before traveling or sending money.
