Clinton County Jail Overview
Clinton County Jail is operated by the Clinton County Sheriff's Office. The researched official sources place the sheriff and jail functions at the county-seat sheriff and courthouse area in Plattsburg. The jail holds local adult pretrial detainees, people arrested by sheriff deputies or municipal police agencies in Clinton County, local sentenced prisoners, and short-term holds accepted by the sheriff. Missouri Section 221.020 places custody and charge of the county jail and prisoners with the sheriff unless a statutory exception applies.
The current official rated capacity was not located on the sheriff or county websites. A high-authority correctional-population table from Prisoners of the Census, using Census 2020 vintage correctional-population data, lists Clinton County Jail with 19 local jail population from a 12/31/2013 source date. That number is useful as a historical population point, not as a current bed count or current daily population.
The Missouri Association of Counties Clinton County listing is one official directory source for sheriff contact details and county office hours.
The county directory helps confirm that jail, sheriff, court, and prosecutor questions often point to the same Plattsburg government area but different offices.
Clinton County Jail Population
The public data picture for Clinton County Jail is thin. No sheriff dashboard, annual jail report, current rated capacity, current average daily population, annual booking count, or demographic breakdown was found in official county sources. The available sourced point is the historical local jail population of 19 from the Prisoners of the Census table. The county's 2020 Census population was 21,184 according to U.S. Census QuickFacts, but that is a county-resident figure and not a jail population figure.
| Measure | Figure | Source and Date |
|---|---|---|
| Clinton County Jail local population | 19 | Prisoners of the Census, 12/31/2013 source data |
| Current rated capacity | Not located | Sheriff and county sources checked June 2026 |
| Current average daily population | Not located | No official dashboard found |
Lookup Clinton County Jail Inmates
Current Clinton County Jail custody is searched through the sheriff-linked inmate portal at getinmate.info/ccm. The official sheriff website also has a roster route at clintoncosheriff.org/roster.php, which loads the sheriff app shell and inmate-services path. Research showed that the vendor portal requires an interactive browser and may load reCAPTCHA assets, so use a browser with JavaScript enabled.
- Open the sheriff-linked inmate portal from the official sheriff site or direct portal URL.
- Search by the name fields shown in the live portal, checking spelling and aliases.
- Open the matching record and verify the person is still in Clinton County Jail custody.
- Call the jail if the portal does not load, the booking is recent, or the person is not listed.
If the person has been sentenced to state prison or is on Missouri probation or parole, use the MODOC Offender Web Search instead. Federal and immigration custody use the BOP inmate locator and ICE Online Detainee Locator. VINELink can help with custody and release notifications where coverage is available.
Clinton County Jail Address
Use the jail and sheriff contact lines for custody confirmation, visiting questions, mail format, and deposit instructions. The sheriff site gives a non-emergency number, and the MAC county directory gives the sheriff office number and mailing reference. Booking and intake are law-enforcement functions, so do not assume county office lobby hours are jail intake hours.

Visit Clinton County Jail
Clinton County did not publish crawlable jail visitation rules, video-visit windows, visitor approval steps, or dress-code rules in the researched official pages. That gap matters because a person may be held locally for a short time and moved quickly after bond, court, or transfer. Call the jail before leaving for Plattsburg, and ask whether visits are in person, video, attorney-only, or suspended for security reasons.
| Visit Topic | Published Detail | Action Before Travel |
|---|---|---|
| In-person visits | Schedule not located | Call jail before arriving. |
| Video visits | Vendor not located | Ask whether video visits are offered. |
| Visitor ID | Rule not published | Ask what photo ID is required. |
| Courthouse entry nearby | Metal detectors and no cell phones in court | Follow courthouse rules when attending court. |
Note: The court page's no-shorts and no-cell-phone rules are courthouse rules, so verify jail lobby rules separately.
Mail and Money at Clinton County Jail
Official jail mail, phone, commissary, and deposit vendor details were not found in crawlable sheriff or county text. Do not send cash, money orders, books, property, or mail until the jail confirms the exact format. Ask whether an inmate ID or booking number is required, whether mail must include a full return address, which items are banned, and whether money can be posted by kiosk, counter, phone, or online service.
| Service | Published Detail | What to Ask |
|---|---|---|
| Format not published | Ask for full inmate-mail format and banned items. | |
| Phone calls | Vendor not located | Ask how inmates place calls and how families fund accounts. |
| Commissary | Vendor and fee schedule not located | Ask what deposits are accepted. |
| Property | Drop-off rules not published | Ask before bringing clothing, medicine, or documents. |
Booking at Clinton County Jail
A local arrest can arrive at Clinton County Jail from a sheriff deputy, municipal police officer, Missouri State Highway Patrol trooper, or other authorized officer. Intake usually includes identification, warrant and hold checks, property inventory, fingerprints or photographs when required, medical and security screening, entry of charges or hold basis, and housing classification. Clinton County did not publish local housing-unit names, medical-unit details, work-release beds, or booking desk hours.
Bond and first appearance are separate from booking. County-specific bond payment instructions were not found on the sheriff site, so verify custody through the jail, then confirm the court order through Case.net or the Clinton County criminal court phone line. A no-bond hold, out-of-county warrant, DOC parole hold, federal detainer, or ICE hold can prevent release even when local bond looks available.
Clinton County Jail Records
For records not visible in the online portal, use a Missouri Sunshine Law request. The Missouri Attorney General Sunshine Law page explains that requests go to the public body that created or keeps the record. RSMo 610.100 makes arrest and incident reports open records subject to statutory closures, while RSMo 610.023 sets the records-custodian and response-timing rule.
A request should include the person's name, arrest date, requested record, and preferred format. Ask for an arrest report, booking record, custody status record, or booking photo as needed. The sheriff-linked crime-tip form is not a records-request form.
Confirm first: Call Clinton County Jail before traveling, sending money, mailing items, or relying on a stale online custody result.
