Criminal Records Missouri: Complete Search Guide

Understanding Missouri's Public Criminal Records System

Missouri is an open-records state. Under the Missouri Sunshine Law, criminal records are treated as public documents, meaning virtually anyone can request them without having to explain why. This makes Missouri one of the more accessible states in the country when it comes to researching someone's criminal background - but the system has layers, and knowing which layer to use can save you significant time and money.

Criminal records in Missouri include arrest records, court case filings, conviction data, sex offender registry entries, corrections records, and probation/parole status. These records are held across multiple agencies - the Missouri State Highway Patrol, the state court system, county sheriffs, and the Department of Corrections - each with its own portal and process. Missouri has 114 counties, and criminal case files are maintained at the county level as well as the state level, which means a truly thorough search sometimes requires checking multiple sources.

The Official State Database: MACHS

The primary hub for Missouri criminal records is MACHS - the Missouri Automated Criminal History Site. Administered by the Missouri State Highway Patrol's Criminal Justice Information Services (CJIS) Division, MACHS is the central repository for all state criminal history files and provides two types of searches to the public.

Name-Based (Personal Identifier) Search

The most accessible option is the name-based search, which uses a person's full name, date of birth, and Social Security number. Any member of the public can request this online through the MACHS Name Search Portal. The fee is $15.00 per request, plus a small convenience fee, and the portal accepts all major credit cards. For most requests, results come back within seconds - though a small number may take up to five business days if CJIS staff need to manually verify a court disposition.

One important caveat: name-based results are considered a "possible match" rather than a definitive positive identification. They only return open records, which include convictions, pending charges, arrest information less than 30 days old, and records under a suspended imposition of sentence (SIS) during the active probation period.

There is one additional detail worth noting: MACHS stores your search results in your account for 30 days. After that period, results are archived and you would need to pay again to run a fresh search. Make sure you enter the subject's name, date of birth, and Social Security number accurately - the system does not allow you to change the search parameters after submission.

Fingerprint-Based Search

For a more comprehensive and legally definitive result, a fingerprint-based search is the gold standard. These searches are conducted through IDEMIA, Missouri's contracted fingerprint vendor, using livescan (electronic image capture) technology. The state-only fingerprint fee is $20.00, plus IDEMIA's service fee of $12.00, bringing the total to $32.00 for a state-only check. A combined state and federal (FBI) background check costs $44.00 per applicant.

Fingerprint-based results are considered a "positive match" and include closed records - meaning dismissed charges, not-guilty findings, and expunged records (for authorized purposes). Processing time is generally seven to ten business days, with results mailed directly to the qualified entity or applicant.

For employers and licensing bodies that need the most thorough check available, fingerprinting is worth the extra cost and wait time. For landlords, individuals doing personal research, or sales professionals vetting a prospect, the name-based MACHS search is usually sufficient.

One optional add-on worth knowing: the CJIS Division can notarize the results of either a name-based or fingerprint-based search for an additional $5.00. This is useful if you need a certified copy of results for legal, licensing, or immigration purposes.

Missouri Courts: Case.net

Running parallel to MACHS is Case.net, the Missouri Courts' automated case management system. Case.net is free to use and lets you search for court case records including docket entries, parties, judgments, and charges in public court. It covers courts across all 114 counties and is searchable by party name, case number, or filing date. The system holds more than 45 million case records, with some records going back to the 1980s.

Case.net gives you four distinct ways to search: by litigant name, by case number, by filing date, or by scheduled hearings. Filters let you narrow results by case status, county, and court type - useful when you're dealing with a common name and want to isolate records from a specific jurisdiction. Each case listing shows the parties involved, docket entries, motions, judgments, and upcoming hearing dates. Criminal case types covered include misdemeanors, felonies, and probation violations.

Case.net is particularly useful for looking up the specific details of a case - the exact charges filed, the outcome, sentencing information, and scheduled hearings. Where MACHS tells you whether someone has a criminal record, Case.net tells you the full story of what happened in court. The two tools complement each other well.

Keep in mind that Case.net only shows cases deemed public under Missouri Revised Statutes, and not every piece of case documentation is available online - some records require a visit to the courthouse's public access terminal.

Other Official Missouri Resources

Missouri Department of Corrections Offender Search

The Missouri Department of Corrections maintains a free Offender Web Search tool at web.mo.gov/doc/offSearchWeb. This application provides information about active offenders currently under DOC supervision, including probationers and parolees. You can search by offender ID or by first and last name. This is the right tool when you specifically want to know if someone is currently on parole or probation in Missouri.

Missouri Sex Offender Registry

Missouri maintains a statewide sex offender registry accessible through the Missouri State Highway Patrol. The registry is available to the public online at the MSHP sex offender search page and can be searched by name, date of birth, or address. An interactive map search is also available, and a toll-free information line is available at 888-767-6747. Criminal records returned through MACHS also include information pertaining to any sex offenders currently registered within the state, even if the underlying sex offense occurred out-of-state. This is important context for landlords, childcare providers, and employers working with vulnerable populations.

Missouri Warrants

A warrant in Missouri is a legal order typically issued by a judge that authorizes law enforcement to take specific actions. Common types include arrest warrants, which authorize the arrest of a person suspected of a crime based on a finding of probable cause, and search warrants, which authorize law enforcement to search a specified person or place for evidence. Outstanding warrants may not always appear in a standard MACHS name-based search - especially if no conviction or disposition has been entered yet. Checking Case.net for open cases or contacting the relevant county sheriff's office can help surface active warrant information.

Local Sheriff and County Databases

Arrest records and jail rosters are maintained at the county level. If you're researching a recent arrest or want to check whether someone is currently in custody, the relevant county sheriff's office website is the best starting point. Many counties - including St. Louis, Jackson, and Greene - have online inmate search tools. For others, a phone call or in-person visit to the courthouse is required.

Walk-In and Mail Options

Not everyone wants to go through an online portal. MACHS checks can also be requested by mail using Form SHP-158, sent to Missouri State Highway Patrol, CJIS Division, P.O. Box 9500, Jefferson City, MO 65102. Mail requests take approximately four to six weeks to process, and payment must be by check or money order made payable to the "State of Missouri - Criminal Record System Fund." Cash, credit cards, and foreign currency are not accepted for mail-in requests.

For those near Jefferson City, walk-in service is available at the public access window at the Missouri State Highway Patrol General Headquarters, 1510 East Elm Street. Name checks at the window typically take about 30 minutes. If you have questions, the CJIS Division can be reached at (573) 526-6153.

What's Actually in a Missouri Criminal Record?

Missouri's Central Repository maintains criminal records dating back to the 1940s. The repository covers state charges - both misdemeanors and felonies - as well as selected ordinance violations reported by municipalities. All law enforcement agencies, prosecutors, courts, and the Department of Corrections are required by statute (43.503 RSMo) to submit criminal information to the repository. Records are updated daily as agencies submit new data.

A typical Missouri criminal record (RAP sheet - Record of Arrests and Prosecutions) includes:

• Arrest information: Date, arresting agency, charges at time of arrest
• Prosecution details: Whether charges were filed, by which prosecutor
• Court dispositions: Guilty pleas, convictions, acquittals, dismissals
• Sentencing data: Fines, probation terms, incarceration details
• Sex offender registration status
• Corrections data: Active supervision, parole, probation

It's worth understanding the distinction between open and closed records. Open records - the kind returned in a name-based MACHS search - include convictions, arrest information less than 30 days old, pending prosecutor-filed charges, and SIS records during probation. Closed records, accessible only through fingerprint-based searches for authorized purposes, cover dismissed charges, not-guilty findings, and expunged records. This distinction matters a great deal depending on the purpose of your search.

Missouri Criminal Record Expungement: What Gets Sealed

Missouri law allows certain records to be expunged under Section 610.140 RSMo. Expungement means the record is closed and sealed from public view - a name-based search on MACHS will not return it. However, fingerprint-based checks may still surface expunged records for authorized purposes.

The waiting periods under Section 610.140 are measured from the date the petitioner completed all court-ordered conditions - meaning the sentence, probation, parole, or any other condition imposed by the court. For eligible felony convictions, the required waiting period is at least three years from completion of disposition. Misdemeanor convictions also require a waiting period before a petition can be filed. Some marijuana-related offenses qualify for automatic expungement under Article XIV of the Missouri Constitution. Not every crime is eligible - there are 11 categories of exceptions in the statute.

Offenses permanently excluded from expungement include Class A felonies, dangerous felonies as defined by Missouri statute, sex offenses requiring registration under Missouri's sex offender registry laws, felonies involving death as an element of the offense, felony assault, domestic assault, kidnapping, and intoxication-related traffic offenses for commercial driver's license holders. In total, it is estimated that more than 1,900 offenses qualify for expungement under the current version of the statute - meaning the law casts a wide net for eligible crimes, even though serious violent and sexual offenses are permanently barred.

Once a court grants an expungement, all named agencies - law enforcement, courts, and the central state repository - are required to close the record. The effect of the order is to restore the person to the status they occupied before the arrest, plea, trial, or conviction, as if those events never took place. After expungement is granted, the person may lawfully answer "no" to most employer inquiries about prior arrests or convictions - with exceptions for certain regulated industries such as banking, insurance, financial services, and positions requiring criminal history disclosure under federal law.

This is important context when interpreting the results of a name-based MACHS search. A clean result doesn't always mean a clean record - it may mean a record was successfully expunged, or that the person has out-of-state criminal history that Missouri's state repository wouldn't capture.

Frequently Asked Questions About Missouri Criminal Records

Can I search someone else's criminal record in Missouri?

Yes. Missouri allows any member of the public to search another person's criminal history through a name-based search on MACHS. You will need the subject's full legal name, date of birth, and Social Security number. The $15.00 fee applies regardless of whether you are searching your own record or someone else's. This open-access policy is a direct result of Missouri's Sunshine Law framework, which treats criminal records as public documents.

How long does a Missouri criminal record search take?

For name-based MACHS searches submitted online, most results return within seconds. A small number of complex cases may take up to five business days. Fingerprint-based searches generally take seven to ten business days, with results mailed to the applicant or qualified entity. Mail-in requests using Form SHP-158 take approximately four to six weeks from receipt of the request and payment.

Are Missouri arrest records public?

Arrest records in Missouri are generally public, but with important limitations. MACHS name-based searches only return arrest information that is less than 30 days old. Older arrest records that did not result in formal charges or convictions may not appear in a standard name-based search. County-level arrest and jail records are maintained separately by sheriff's offices, and many counties offer online inmate search tools for more recent booking information.

What is a suspended imposition of sentence (SIS) in Missouri?

An SIS is a sentencing outcome in which the court withholds a formal conviction and places the defendant on probation. During the probation period, the SIS record is considered open and will appear in a MACHS name-based search. However, if probation is successfully completed, the SIS record becomes a closed record and will no longer appear in a public name-based search - though it remains accessible through authorized fingerprint-based searches. This is a common source of confusion when interpreting MACHS results.

When You Need More Than a State Search

The official Missouri channels are solid for in-state records, but they have limitations. They don't cover other states, they have fees attached, and the fingerprint option requires scheduling and waiting. For professionals - landlords screening tenants, sales teams vetting high-value prospects, HR teams running pre-employment checks, or property investors doing due diligence - a tool that aggregates nationwide criminal data in one place is far more efficient.

That's exactly what Galadon's Criminal Records Search is built for. It pulls from sex offender registries, corrections records, arrest records, and court records nationwide - not just Missouri - without requiring you to navigate individual state portals. You get a consolidated picture rather than a patchwork of separate searches.

If you're also doing property due diligence in Missouri - say, checking the background of a property owner before a transaction - you can combine the Criminal Records Search with Galadon's Property Search tool, which surfaces owner names, phone numbers, emails, and address history for any US address. Running both together gives you a genuinely thorough picture of who you're dealing with.

For HR teams and recruiters who need to go deeper than criminal history alone, Galadon's Background Checker generates comprehensive background reports with trust scores - pulling together multiple data points into a single consolidated report rather than requiring manual cross-referencing across different portals.

Practical Use Cases: Who Searches Missouri Criminal Records and Why

Landlords and Property Managers

Missouri landlords routinely run criminal background checks on prospective tenants. For single-family rentals and smaller landlords, the MACHS name-based search at $15 per applicant is manageable. For property managers handling high volumes of applications, a tool that batches checks without per-search fees becomes more cost-effective quickly. Keep in mind that Missouri does not currently have statewide rent control or specific ban-the-box rules for private housing providers, giving landlords relatively broad discretion in how they factor criminal history into rental decisions - though fair housing laws still apply.

Employers and HR Teams

Missouri does not have a blanket ban-the-box law for private employers statewide, though certain cities and counties have their own ordinances. Employers in regulated industries - healthcare, childcare, elder care, financial services - often need the full fingerprint-based check that surfaces closed records. For general pre-employment screening, the name-based MACHS search or a third-party background tool is standard. Employers should also be aware that once a record has been expunged, candidates may lawfully answer "no" to questions about prior convictions - except in cases where the employer is required by federal or state law to exclude applicants with certain convictions.

Individuals Checking Their Own Record

One of the most common reasons people search Missouri criminal records is to check what an employer or landlord will see about them. Missouri residents can request their own records through MACHS using the same process as any other requestor. If you find an error in your record, the CJIS Division is the point of contact to initiate a challenge or correction. Individuals who believe they may qualify for expungement should consult with a licensed Missouri attorney before filing a petition, as eligibility is fact-specific and the application process requires naming all law enforcement agencies and courts that may hold relevant records.

Sales Professionals and B2B Due Diligence

High-value B2B transactions - partnerships, vendor agreements, executive hires - sometimes warrant a background review of key individuals. A quick criminal records check combined with a comprehensive background check can surface issues before a deal is signed rather than after. This is especially relevant in industries like real estate, financial services, and professional services where fiduciary relationships are at stake. Galadon's suite of free tools makes it straightforward to layer these checks - for instance, using the Email Finder to locate a contact's professional email before running a background check on the same individual.

Step-by-Step: Running a Missouri Name-Based Criminal Records Check

1. Go to MACHS at machs.mo.gov and select the Name Search Portal.
2. Create an account or log in if you've used the system before.
3. Enter the subject's information: full legal name, date of birth, and Social Security number. Double-check these for accuracy - you cannot change them after submission.
4. Pay the $15.00 fee plus the convenience charge using a major credit card.
5. Receive results - for most searches, within seconds. A small number of complex cases may take up to five business days.
6. Review the output: Results will show open records only. If nothing appears, it either means no open criminal history exists, records have been expunged, or the individual's history is limited to closed records that don't surface in a name-based search.
7. Cross-reference with Case.net for detailed court case information on any hits you find. Use Case.net's litigant name search and filter by county and case type to isolate relevant criminal cases.
8. Check the DOC Offender Search if you need to confirm current parole or probation status.
9. Run a nationwide search using Galadon's Criminal Records Search if you need coverage beyond Missouri's borders.

Comparing Your Search Options: A Quick Reference

The Bottom Line on Missouri Criminal Records

Missouri's public records infrastructure is genuinely accessible compared to many states. Between MACHS, Case.net, the DOC Offender Search, and local county systems, a determined researcher can piece together a reasonably complete picture of someone's in-state criminal history without paying for a commercial service.

That said, the official route has friction: multiple portals, per-search fees, mail-in delays, and a hard stop at the state line. If you need speed, national coverage, or volume - Galadon's free Criminal Records Search is the tool to start with. It aggregates sex offender registries, corrections records, arrest records, and court data from across the country in one place, at no cost.

Whether you're a landlord, an HR professional, an investor, or simply someone who wants to know more before making a decision - understanding how Missouri's criminal records system works puts you in a much stronger position than starting blind.
