The Franklin County Inmate Population
The best local count for the Franklin County inmate population comes from the official Franklin County detention page. That page describes the Franklin County Adult Detention Facility as the county jail for civil detainees, first-time arrestees, people awaiting judicial action, people serving court-ordered sentences, and municipal detainees from inside Franklin County. The same source reports a 2024 daily average of 175 detainees and a one-day high of 230 detainees. Those figures describe the county jail population, not the sentenced state-prison population at Missouri Eastern Correctional Center.
Franklin County custody is split by legal stage. A person arrested by the sheriff or by a city police department may be booked at the Adult Detention Facility in Union. If that person is later sentenced to the Missouri Department of Corrections, the lookup moves to MODOC. Federal and immigration custody are separate systems. This is why the Franklin County inmate population has to be read as a map of agencies rather than as one list.
The county's official detention page is the source for the local jail population, bail, visitation, commissary, phone, and mail details used here.
That page is especially important because it supplies the county's own 2024 detainee counts while also showing that public access relies on office channels rather than a public roster form.
Franklin County Inmate Population Statistics
Franklin County publishes useful local population numbers but does not publish every metric that readers often expect. The county gives average and high-day detainee counts for 2024 and says thousands of detainees pass through the jail each year. The official page does not list a rated capacity or a demographic table. Older correctional-facility data from the Prison Policy Initiative gives a historical local jail population snapshot, but it should not be mixed with the 2024 county count as if both used the same method.
| Measure | Figure | Source / Year |
|---|---|---|
| Adult Detention Facility average daily detainees | 175 | Franklin County detention page, 2024 |
| Highest one-day detainee count | 230 | Franklin County detention page, 2024 |
| Annual throughput | Thousands | Franklin County detention page, inspected 2026 |
| Rated capacity or bed count | Not located | No official county figure in the research file |
| Older Census correctional facility snapshot | 125 | Prison Policy Initiative Census 2020 vintage data, source date 12/31/2013 |
Franklin County Inmate Population Trends
The local trend data is limited, but the available numbers still show the right scale. The older 2013 correctional-facility snapshot listed 125 people at the Franklin County Jail. The county's 2024 daily average was 175, with a high day of 230. That does not prove a formal rate change because the sources are not the same reporting program. It does show why a current Franklin County inmate population search should use the county's live office channels rather than old directory pages.
| Year or Date | Population | Note |
|---|---|---|
| 12/31/2013 | 125 | Prison Policy Initiative facility snapshot for Franklin County Jail |
| 2024 daily average | 175 | Official county detention count |
| 2024 one-day high | 230 | Official county detention count |
| Midyear 2023 national context | 664,200 | BJS national local jail population, not county-specific |
Who Makes Up Franklin County Inmates
The county does not publish a full demographic breakdown by sex, race, age, charge level, or hold agency in the located sources. It does define the custody groups held in the Adult Detention Facility. That is more useful than a generic roster label because it shows why a city arrest in Union, Washington, Pacific, or St. Clair may still become a Franklin County jail record.
- Pretrial detainees: People waiting for court action after arrest or after a bond decision.
- Court-ordered sentence detainees: People serving a local sentence in the county jail.
- Civil detainees: People held under a civil process or court order.
- Municipal detainees: People arrested by city agencies inside Franklin County and housed by the county jail.
- Sentenced state residents: People in MODOC custody at Missouri Eastern Correctional Center are in state prison, not county jail.
Laws Governing Franklin County Jail Records
Missouri law explains why jail, arrest, booking, and court records are not all handled by one office. The sheriff has custody of the county jail. Law-enforcement agencies maintain arrest and incident records. Courts keep the filed criminal case. Corrections agencies keep state-prison records after sentencing. A Franklin County inmate population search is more accurate when those legal lines are kept clear.
Key Statutes:
RSMo 610.011 states Missouri's policy that public governmental records are open unless a law says otherwise.
RSMo 610.100 covers law-enforcement incident and arrest records, including arrest and detention information subject to exceptions.
RSMo 221.020 places custody and charge of the county jail with the sheriff unless a statute creates a different rule.
RSMo 221.300 requires jail inspection and reporting on jail condition and prisoner treatment.
Franklin County and State Prison Inmates
Missouri Eastern Correctional Center sits in Pacific, inside Franklin County, but it is not a county jail. It is a Missouri Department of Corrections prison for sentenced residents. MODOC lists the prison as medium and minimum security. Its family page says the facility opened in 1981, covers about 42 acres, and offers educational, vocational, work, and volunteer programs. Those residents are part of the state-prison system, so the correct lookup is the MODOC Offender Search.
A Franklin County arrest may begin in local booking, move through the Circuit Court, and later become a DOC sentence. Once custody transfers, the county detention phone is no longer the main lookup source. MODOC search shows active offenders, including aliases, and requires a captcha. It does not show discharged offenders, and some records can be withheld for safety, security, or confidentiality reasons.
How to Search Franklin County Inmates
No official public Franklin County, Missouri jail roster was located on the county or sheriff domain. That negative finding matters. Search results for other Franklin Counties can lead to Alabama or Arkansas records, not Missouri custody. Start with the Franklin County Adult Detention Facility and move through the documented access channels before using any third-party roster.
- Call Detention/Booking at (636) 582-8600 or the Sheriff's Office main line at (636) 583-2560.
- Have the full legal name, date of birth if known, approximate arrest time, and arresting agency.
- For a detainee ID or account question, call (636) 583-2560 and ask for extension 1210 for the Commissary Deputy.
- For a filed criminal case, search Missouri Case.net or call the Franklin County Circuit Clerk.
- For sentenced state custody, use MODOC. For federal prison, use BOP Inmate Locator. For immigration custody, use ICE ODLS.
Current Franklin County Custody Lookup
The current-custody path is a fallback chain because the county does not expose a public roster form in the located official sources. The jail can answer detention and booking questions by phone. The sheriff accepts records requests by email, fax, phone, in person, or mail. The County Clerk is the countywide Sunshine request contact. MOVANS and VINELink can help victims track release, transfer, and court-date changes.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| No official public roster located | n/a | n/a | Use detention phone, sheriff records, County Clerk Sunshine route, MOVANS, Case.net, MODOC, BOP, or ICE depending on custody stage. |
What Franklin County Inmate Records Show
Franklin County does not publish a public roster field list, so the official county pages prove only some record elements. The detention page proves detainee ID numbers exist because they are needed for Access Corrections deposits and scanned mail. It also proves bond payments, court status, and release questions may require the court, not just jail staff. Arrest-report access comes through Missouri Sunshine Law and the sheriff records process.
| Field | What It Shows |
|---|---|
| Detainee name | Used for bond payments, deposit searches, and records requests. |
| Detainee ID number | Needed for Access Corrections deposits and scanned mail addressing. |
| Custody status | Can be checked through jail staff and MOVANS/VINELink when available. |
| Charges | Booking allegations may differ from charges later filed in court. |
| Bond | Payment and release status can change after court action. |
| Release or transfer | May require jail, court, MOVANS, or DOC confirmation. |
County Jail vs State Prison Lookup
Franklin County jail records and Missouri state-prison records answer different questions. A newly arrested person, a pretrial detainee, or a short local sentence belongs in the county channel. A sentenced state prisoner belongs in MODOC. A federal prisoner belongs in BOP after federal commitment, while federal pretrial detainees may be held under U.S. Marshals arrangements and may not appear in BOP the same way.
| Question | County Jail | State Prison |
|---|---|---|
| Run by | Franklin County Sheriff's Office | Missouri Department of Corrections |
| Who it covers | Pretrial, local sentences, municipal detainees, civil detainees | Sentenced MODOC residents, probationers, and parolees |
| Lookup route | Detention phone, sheriff records, Sunshine request, MOVANS | MODOC Offender Search |
| Local facility | Franklin County Adult Detention Facility | Missouri Eastern Correctional Center |
Franklin County Detention Facilities
Franklin County has two official facilities that matter for inmate population research. The county jail in Union handles local custody. Missouri Eastern Correctional Center in Pacific handles sentenced state custody. No separate official municipal jail roster, BOP prison, or ICE detention center was located in Franklin County sources.
- Franklin County Adult Detention Facility - county jail for pretrial detainees, municipal detainees, civil detainees, and court-ordered local sentences.
- Missouri Eastern Correctional Center - state prison in Pacific for sentenced Missouri Department of Corrections residents.
Franklin County Records Requests
The Sheriff's Office records channels are the practical route when a booking, arrest report, custody status, or mugshot is not available online. Requests for sheriff records may be sent to the Sheriff's Office by email at fcsorecords@franklinmo.gov, fax at (636) 584-6877, phone at (636) 583-2560, in person during business hours, or mail to Attn: Records, #1 Bruns Lane, Union, MO 63084. For broader county Sunshine requests, the County Clerk Sunshine page says to contact the Clerk's office for the request form.
Readers should not use a commercial roster result just because it ranks for Franklin County. The research found false-local results for other states. Missouri records should trace back to Franklin County, Missouri government, Missouri courts, MODOC, VINELink, BOP, ICE, or a records request.
