Platte County Detention Center Overview
Platte County Detention Center is the central adult detention facility operated by the Platte County Sheriff's Office Detention Division. It is a county jail, not a Missouri prison. The facility holds adult pretrial detainees, people serving local sentences, people charged with state offenses while still in county custody, federal detainees, and ICE or other federal detainees when they are lodged there under county arrangements.
The facility is the only full detention facility identified in official sources for Platte County. City police departments may process arrests, and municipal or circuit courts may issue warrants, but the researched facility map did not identify a separate public municipal jail roster that needed its own facility page. That means most local adult custody questions come back to this detention center or to a transfer into state, federal, or immigration custody.
The official screenshot source for the sheriff's Detention Division page shows the roster, handbook, visitation, commissary, mail, bonding, and attorney links in one place.
That source is the best first stop because the facility's lookup, visit, mail, and money paths are all tied to the same detention division.
Platte County Detention Capacity
The sheriff's detention page and sheriff biography use a current 180-bed figure for the Platte County Detention Center. County population planning reports give more detail. The 2023 update lists 154 design beds and 180 current beds after added bunks. The planning figure used for normal general-population analysis is lower, at 151 beds, because holding cells are not ordinary housing and one safety cell has no bunk.
The building has female Dayrooms A and B, male Dayrooms C through G, a male trusty area, and holding cells. The distinction between bed types matters because an operational number can include added bunks while planning reports still warn that not every bed is fit for normal long-term housing. A person looking at population data should cite the exact source and bed definition, not just a single capacity number.
Lookup Platte County Detention Inmates
The correct lookup path for this facility is the Platte County Current In-Custody/JailTracker roster linked from the sheriff's detention page. The roster covers people currently housed at this county jail. It should not be used to find discharged Missouri DOC offenders, BOP-only prisoners, or an ICE detainee who is no longer lodged in Platte County. If the person is sentenced to prison, use the Missouri Department of Corrections offender search. If federal or immigration custody is likely, use the BOP inmate locator or ICE locator.
- Open the sheriff's detention page and choose the Current In-Custody/JailTracker roster link.
- Search by name and compare identifiers carefully, especially when the person has a common last name.
- Open the inmate profile to review custody status, housing or cell block, charge, court, and bond information when posted.
- Use the cell block to find the correct public visitation schedule if a visit is planned.
- Call 816-858-2424 or use the records request form if the person does not appear but may have been booked, transferred, or released.
Court information on the jail profile can lag because the sheriff FAQ says court data is updated after it is received and verified. Formal filed charges, docket entries, and later dispositions belong in Missouri Case.net and the Platte County Circuit Clerk's records, not only in the jail profile.
Platte County Detention Contact
Use the detention center address for custody visits, legal mail, and facility-specific contact. Do not confuse it with the sheriff administrative address in Kansas City. The detention center sits in the Platte City government and courthouse area, while the sheriff administrative office is listed separately by county government. The main detention and sheriff phone number is the practical contact point for custody confirmation when the roster is unclear.
Platte County Detention Center
415 Third Street, Suite 10
Platte City, MO 64079
816-858-2424
Adult county detention center operated by the Platte County Sheriff's Office.
General sheriff administration is listed at 11724 NW Plaza Circle Drive, Kansas City, MO 64153, with weekday administrative hours. That office may help with general sheriff business, but inmate visits, inmate mail, and custody details should be tied back to the detention center and its official detention pages.
Platte County Detention Visits
Public visitation at Platte County Detention Center is through free public kiosks during non-lockdown periods. The official process starts with the roster, because visitors need the inmate's cell block to find the correct visitation schedule link. Professional visits use separate attorney enrollment and attorney or professional Webex request channels linked from the detention page.
| Visit type | Official detail | Practical step |
|---|---|---|
| Public kiosk visitation | Free public kiosks during non-lockdown periods. | Confirm custody and housing before arrival. |
| Cell-block schedule | Find the inmate in Current In-Custody and use the cell-block schedule link. | The schedule depends on where the person is housed. |
| Attorney or professional visit | Attorney enrollment and Webex professional visit forms are linked by the jail. | Use the professional route instead of public kiosks. |
| Lockdown or emergency limits | Visits are offered during non-lockdown periods only. | Call first if travel or court timing is tight. |

Because the schedule depends on the cell block, the inmate roster is part of visit planning even when the visitor already knows the person is in custody.
Platte County Mail and Commissary
Mail and money rules at Platte County Detention Center are specific. Non-legal and non-government incoming mail is sent to a scanning address in Jonesboro, Arkansas, not to the detention center street address. Legal, confidential, or privileged mail can be sent to the detention center when it is clearly marked and includes sender information. Legal mail is opened in the detainee's presence for contraband but is not read.
| Service | Provider or address | Rule |
|---|---|---|
| Non-legal mail | Platte County Jail, detainee name and ID, P.O. Box 16120, Jonesboro, AR 72401 | Scanned mail is delivered through kiosk or tablet inbox. |
| Legal mail | Platte County Detention Center, C/O detainee name, cell, Alien number if applicable, 415 Third Street, Suite 10, Platte City, MO 64079 | Must be marked Legal Mail, Confidential, or Privileged. |
| Commissary deposits | Kiosk outside the visitation entrance or Access Corrections | Staff do not accept money orders, cash, or checks by mail for commissary. |
| Email and SMS | JailATM/InmateCanteen | Messages are subject to monitoring. |
| Phone accounts | CenturyLink Inmate Communications or ICSolutions | Accounts can be set up through ICSolutions or by phone with the vendor. |
The official screenshot source for Platte County inmate mail procedures shows the scanned-mail model and legal-mail distinction.
Mail sent to the wrong address or with missing detainee details can fail, so the current custody profile and jail mail rules should be checked before anything is mailed.
Platte County Commissary Rules
Commissary access depends on funds in the inmate account and facility rules. The sheriff's commissary page says inmates order through a dayroom kiosk if they have funds, and the official sources describe distribution as twice weekly on the web page. The handbook snippet found in research describes once-weekly Saturday distribution with a Wednesday order cutoff, so users should verify the current schedule with the facility when the timing matters.

The key limit is that detention staff do not process mailed commissary deposits. If a person is released before receiving an order, the sheriff's commissary rules say the released person has five business days to claim it and refunds are not provided.
Platte County Booking Intake
Booking at Platte County Detention Center follows arrest or lawful commitment by an agency or court. Missouri law places custody and keeping of the county jail with the sheriff unless another law provides otherwise, and jailers receive people committed by lawful authority. Intake includes identification, property handling, medical and mental-health screening, classification, housing assignment, and review of bond or hold status.
Missouri law also allows medical review before acceptance when a person appears unconscious, seriously ill, seriously injured, or seriously impaired by alcohol or drugs. That means a person may be taken for medical clearance before a jail booking becomes visible. After booking, the jail profile may show charges and bond details, but the prosecutor and court can later change the charge record when a case is filed.
A simple custody flow is: arrest, booking, classification, bond or first appearance, court filing, continued county custody or release, and then transfer to Missouri DOC, BOP, ICE, or another agency if the legal status changes. Each point can place the record in a different system.
Platte County Federal Holds
Platte County Detention Center can house local, state, and federal detainees. County reports also track ICE detainees separately, which shows why federal and immigration lookup paths matter even though no separate BOP prison or ICE detention center was identified in Platte County. A federal pretrial detainee may be in U.S. Marshals custody and lodged at the county jail, while a sentenced federal prisoner may later appear in BOP systems.
For Missouri state prison custody, use Missouri DOC's active offender search. For BOP custody, use the federal inmate locator, which covers federal inmates from 1982 to present. For ICE, USAGov explains that searches can use A-number with country or name, country of birth, and birth date. The county roster applies only when the person is actually lodged at Platte County Detention Center.
Note: A hold or detainer can prevent release even when a Platte County bond amount appears on the jail profile.
