Atchison County Jail Overview
Atchison County Jail is operated by the Atchison County Sheriff's Office. The official local contact block lists Sheriff Andy Riley, Atchison County Jail, 511 W. Clay, Rock Port, MO 64482, phone 660-744-6271, and fax 660-744-6274. The jail is the only detention facility in Atchison County verified through the located official local sources. No state prison, BOP facility, ICE detention facility, private federal-contract jail, regional jail, or separate city jail page was found inside the county.
The facility functions as a local adult jail and short-term detention point. The researched population categories are people arrested in Atchison County awaiting court, people held on warrants, and local sentenced misdemeanants when accepted by the sheriff. Exact housing classifications were not published. The sheriff has custody and charge of county jails and prisoners under Missouri law unless another statute provides otherwise, so current county-jail custody questions should start with this office.
The Atchison County local-government page repeats the sheriff non-emergency line and ties the office to the W. Clay address.
That local-government source also helps route court, police, and courthouse questions when a jail booking turns into a filed criminal case.
Atchison County Jail Contact
The jail and sheriff's office are not listed at the courthouse address. The jail contact block belongs to the W. Clay location in Rock Port. Families, attorneys, bond contacts, and records requesters should use the jail phone for current custody questions before traveling, mailing property, or sending funds. Courthouse questions, filed charges, and court records use the circuit clerk or Case.net after a case exists.

Atchison County Jail Population
No official Atchison County Jail capacity, current jail population, average daily population, annual bookings, housing-unit chart, bed rating, or demographic breakdown was located in the county, elections, Missouri Association of Counties, or local-government sources. No public jail dashboard or official roster was found. This is a confirmed research gap and should be treated as a phone or records-request item, not filled with another county's data.
| Measure | Located Finding | Best Next Step |
|---|---|---|
| Rated capacity | Not located in official Atchison County sources | Call the jail or request the jail census or capacity record. |
| Current population | No official online dashboard or roster located | Ask the jail whether a current count can be confirmed. |
| Average daily population | No official county report located | Request any jail population report under Sunshine Law. |
| Demographic breakdown | Not located by sex, race, age, charge level, or hold type | Request only if needed and expect redaction or nonexistence. |
Atchison County Jail Lookup
No official Atchison County, Missouri online jail roster or inmate search portal was located. That means there is no confirmed county web form to search by name, booking number, date, or housing unit. Do not use Atchison County, Kansas jail pages for this Missouri jail. Those Kansas pages have different facility facts and do not answer Missouri custody questions.
- Call Atchison County Jail at 660-744-6271 and ask whether the person is currently in custody.
- Provide the full legal name, date of birth or approximate age, arrest date, arresting agency, and any case number.
- If charges have been filed, search Missouri Case.net by litigant name or case number.
- For sentenced state custody, search Missouri DOC Offender Search, which covers active DOC-supervised offenders.
- For federal prison or immigration detention, use BOP Inmate Locator or ICE ODLS.
Missouri VINELink may help with custody notifications if the relevant agency participates. It should be checked as a notification channel, not as proof that an Atchison County Jail roster exists.
Atchison County Jail Visits
No official Atchison County Jail visitation schedule, video-visitation vendor, visitor application, ID rule, dress code, minor-visitor rule, attorney-visit procedure, lobby check-in time, or public-counter hours were located. Visitors should call the jail before arriving. Confirm whether visits are in person or remote, whether scheduling is required, whether a government ID is required, where to enter, where to park, and what property cannot be brought inside.
| Topic | Official Atchison County Finding | Action |
|---|---|---|
| In-person schedule | Not located | Call 660-744-6271 before traveling. |
| Video visits | Not located | Ask whether remote visits are offered and which vendor is used. |

Note: Confirm custody and visit approval with Atchison County Jail before driving to Rock Port.
Atchison County Jail Mail
No official Atchison County Jail mail format, inmate ID format, mail inspection rule, phone vendor, tablet vendor, commissary vendor, deposit method, kiosk location, online payment link, or fee schedule was located. The only accurate instruction is to call before mailing or sending money. Ask whether mail must include a booking number, whether photos or cards are allowed, whether funds can be sent by money order, whether a kiosk or online system exists, and what fees apply.
| Service | Located Detail |
|---|---|
| Mail Address | Confirm exact inmate mail format with the jail before sending anything. |
| Phone / Video | No county jail communications vendor was located. |
| Money Deposit | No commissary or deposit vendor and no fee schedule were located. |
| Property | No public property-release rule was located. |
Missouri DOC mail, visiting, and JPay money-transfer rules are separate state-prison rules. They should not be treated as Atchison County Jail rules unless the person has already transferred to DOC custody.
Atchison County Jail Booking
A typical local arrest can involve the sheriff's office, Rock Port Police, Tarkio Police, Missouri State Highway Patrol, or another agency. The person may be transported to Atchison County Jail or an appropriate booking point. Jail staff usually identify the person, note the arresting agency and charge basis, inventory property, screen for safety and medical needs, and hold the person until release, bond, transfer, or court action. Atchison County did not publish a local booking workflow, so specific intake steps must be confirmed by phone.
Missouri law gives important timing context for some arrests. RSMo 544.170 addresses confinement after an arrest without warrant or other process and generally requires discharge within twenty-four hours unless the person is charged and held by warrant. That rule is not the same as a promise that a case will appear online within a day. In Atchison County, no online booking feed was located, so call the jail first and then check court records after filing begins.
Atchison County Jail Records
Public-records requests for Atchison County Jail booking records, arrest reports, booking photos, jail census data, or non-confidential jail policies should be directed to the sheriff or custodian at the jail address. RSMo 610.023 requires a public records custodian and a response by the end of the third business day unless reasonable cause delays the response. RSMo 610.100 defines Missouri law-enforcement arrest and incident reports and says those reports are open unless closure or redaction provisions apply.
Write the request with enough detail to identify the record: full name, date of birth if known, date of arrest or incident, arresting agency, case number if known, and the exact record requested. Ask for electronic delivery if available and ask for advance notice of any fee. Medical records, confidential investigative material, juvenile matters, victim details, and other protected information may be redacted or withheld.
The Missouri records-custodian statute is the response rule for a written Atchison County Jail request.
Use the custodian statute with RSMo 610.100 when the record sought is a jail arrest report, booking record, or booking photograph.
Atchison County Jail Transfers
Atchison County Jail custody is only one part of the record path. Once a prosecutor files charges, Missouri Case.net and the Atchison County Circuit Clerk are the better sources for filed charges, docket entries, hearing dates, and dispositions. Local sources list the circuit clerk through the courthouse phone system and identify the prosecutor as Dan Smith. Booking charges can differ from filed charges, so jail custody and court records should be checked separately.
If a person is sentenced to state prison or placed under Missouri probation or parole supervision, Missouri DOC Offender Search becomes the main custody locator. No DOC adult institution was located in Atchison County itself. If a person is in federal sentenced custody, use BOP. If immigration custody is possible, use ICE ODLS. A local bond may not clear another county warrant, state hold, federal hold, or immigration detainer.
About Atchison County Jail
Atchison County Jail sits in Rock Port, the county seat of Missouri's northwesternmost county. Visitors coming from Interstate 29 generally use the Rock Port exit and local streets to reach W. Clay Street. No public transit route, visitor parking instruction, accessible entrance note, or lobby entrance map was located in official sources. Before travel, confirm route, parking, entrance, ID requirements, and whether weather or rural road conditions may affect the trip.
No official jail program page was located for GED services, work release, substance-abuse programming, religious services, grievance processes, PREA reporting, reentry services, or medical request procedures. Missouri law does require jailers to obtain necessary medical, dental, or medicine attention for sick county prisoners in qualifying circumstances. Program and condition details should be confirmed with the jail or requested as records where public.
