Find the appropriate public record

Where to Search DuPage County Criminal Records Online

DuPage County criminal record information is maintained by different agencies. The Circuit Clerk maintains court files, police agencies maintain arrest and incident reports, and the Illinois State Police maintains statewide criminal-history information.

Public criminal case lookup

How to Search DuPage County Criminal Records by Name or Case Number

The Clerk’s Public Information Application provides several case-related services.

According to the official portal, users can search cases, view available docket entries, check case status and find the next court date.

Step-by-step criminal case search

1. Open the official case lookup

   Visit the DuPage Circuit Clerk website and select Pay Online and Case Lookup. Follow the live production-system link if the page displays a test-system warning.

2. Complete the human-verification requirement

   The Clerk’s public application may display a security check before showing the available search fields.

3. Choose the search method

   Select Case Number, Case Name, or Ticket/Complaint Number as appropriate.

4. Enter the criminal case information

   For a name search, use the defendant’s full last name and available first name, middle name or date of birth. For a case-number search, enter the exact identifier.

5. Submit the search

   Review possible matches and compare the filing court, case number, defendant and available case type.

6. Open the correct record

   Review the case summary, publicly accessible docket activity and listed court dates.

7. Find the charge disposition

   Look for entries showing a plea, guilty finding, dismissal, acquittal, sentencing or another recorded outcome.

8. Request an official court document if needed

   If you require proof of conviction or dismissal, ask the Circuit Clerk for a certified Statement of Charge and Disposition or another appropriate certified document.

What fields are available when searching by name?

The Clerk’s published search interface identifies the following party-search fields:

• Full last name
• First name
• Middle name
• Birth date, entered in MM/DD/YYYY format
• Person or organization search type

A case-number search is usually more precise than searching by name alone.

Can you search by ticket or complaint number?

Yes. The public application includes a Ticket/Complaint Number search with an arresting-agency selection.

This can be useful for certain criminal traffic or misdemeanor proceedings when you have the number printed on the citation.

Understand the criminal case identifier

DuPage County Criminal Case Numbers: CF, CM, DT and TR

Illinois criminal and traffic case identifiers often include a filing year, case-type code and sequence number.

The code can help determine the general type of proceeding, but it does not prove that the defendant was convicted.

What does a DuPage felony case number look like?

A typical identifier may have a format such as 2026 CF 123, depending on how the court’s system displays the number.

Here, 2026 represents the filing year, CF identifies the felony category, and the final digits are the case sequence.

This is an illustrative format, not a reference to an actual defendant.

Why are older records harder to find?

Historical files may use earlier numbering conventions, archived records or documents not available through the current public online system.

If an older case cannot be located electronically, provide the approximate year, name and case details to the Circuit Clerk.

Public courthouse records

DuPage County Courthouse Criminal Records Office in Wheaton

The Clerk of the 18th Judicial Circuit maintains original Circuit Court records for DuPage County.

Can anyone inspect DuPage criminal court files in person?

The Clerk states that its court records are open to the public during regular business hours unless a statute or court order impounds, seals or otherwise restricts the case.

The Clerk provides computerized information terminals for public viewing at the courthouse.

These terminals may help locate available details or documents beyond the basic online search summary.

How to inspect criminal records at the courthouse

1. Find the court case information

   Search online first when possible, and note the exact case number and defendant name.

2. Call the Criminal/Traffic Department

   Ask whether the requested file is public, available at a terminal or held in an archive.

3. Visit the courthouse

   Go to 505 N. County Farm Road, Wheaton, during posted Clerk office hours.

4. Use a public information terminal

   Locate the eligible case record and review the available public information.

5. Identify specific documents

   Write down the filings you need copied, such as the judgment, sentencing order or disposition.

6. Pay applicable document fees

   Inspection of publicly available electronic case information is free, while printed or certified copies may carry charges.

Official conviction and disposition documents

How to Obtain Certified DuPage County Criminal Court Records

A public case summary may show that a charge was dismissed or a defendant was convicted. However, some legal and administrative purposes require a certified document issued by the Circuit Clerk.

DuPage provides two especially useful options:

How to order criminal case documents through I2File

   Follow the approved payment and document-delivery instructions.

What if the case file is unavailable online?

Call the Criminal/Traffic Department at 630-407-8600 and ask whether the relevant public filing can be inspected at the courthouse or retrieved through a records request.

Search local criminal cases accurately

DuPage County Criminal Records by City: Naperville, Wheaton, Downers Grove and More

Criminal cases involving DuPage County communities are generally filed through the county’s Circuit Court system when the prosecution belongs to Illinois state court jurisdiction in DuPage County.

Some municipalities extend across county lines, so a city’s name does not always establish the filing county.

What if the case was filed in another Illinois county?

Illinois maintains court records through county Circuit Clerks.

Use the official Illinois Circuit Court Clerks directory to locate the proper jurisdiction and avoid searching the wrong county.

Statewide criminal-history information

DuPage County Background Checks vs. Illinois State Police Criminal History

A DuPage County Circuit Court case search does not represent every arrest or conviction in Illinois.

The Illinois State Police Bureau of Identification maintains statewide criminal-history information under applicable Illinois laws.

Two official services are particularly important: the Uniform Conviction Information Act (UCIA) process and personal Access and Review.

Illinois State Police UCIA fees

The Illinois State Police fee schedule effective October 1, 2026, lists these charges:

Fingerprint vendors may charge a separate collection or processing fee.

CHIRP access is subject to the State Police’s authentication and user-agreement requirements. It should not be described as an unrestricted anonymous search portal.

How to obtain your own Illinois criminal-history record

1. Review the Access and Review instructions

   Open the official Illinois State Police Viewing My Record page.

2. Select a participating fingerprint provider

   Choose a qualifying law-enforcement agency, correctional facility or licensed fingerprint vendor.

3. Provide accepted identification

   Follow the fingerprinting provider’s identity-verification requirements.

4. Complete fingerprint submission

   The provider forwards the fingerprints and required identifying information to Illinois State Police.

5. Receive the personal criminal-history transcript

   ISP sends the transcript or a written statement that no criminal history was found through its approved process.

6. Challenge an error when necessary

   Use the Record Challenge form to dispute an incorrect arrest, identity or court disposition entry.

Police records are separate from court dockets

How to Request DuPage County Arrest Records and Police Reports

An arrest record or police incident report is generally maintained by the law-enforcement agency that created it.

The DuPage County Sheriff’s Office maintains records created by Sheriff’s deputies, including incident reports, traffic crash reports and jail booking files.

How to request a Sheriff’s incident report

1. Confirm the Sheriff’s Office created the report

   If a municipal police department handled the incident, request the report from that department instead.

2. Collect the incident details

   Note the incident date, location, report number and type of record needed.

3. Contact the Sheriff’s Records Division

   Ask about the appropriate records-request or Freedom of Information Act procedure.

4. Submit the request

   Provide the required information and any identification or authorization requested for a legally restricted record.

5. Check applicable charges

   Confirm whether the report is available without charge or whether reproduction fees apply.

6. Review the released information

   Some records may be redacted or withheld under applicable laws and court orders.

Sheriff’s Office police report fees

The Sheriff’s Records Division accepts checks, debit cards and credit cards. It states that cash is not accepted.

Custody and jail records

DuPage County Jail Records and Current Booking Information

The DuPage County Correctional Facility is operated by the DuPage County Sheriff’s Office.

It maintains jail-related information for qualifying people in local custody.

How to find custody information

1. Identify the person’s full name and any available booking details.
2. Determine whether the person was arrested by a municipal police department or the Sheriff’s Office.
3. Contact DuPage County Corrections/Booking at 630-407-2255.
4. Ask about the permitted custody or booking information.
5. Use the Circuit Clerk’s public case search to identify the corresponding criminal court proceeding.

The Sheriff’s Office is the appropriate local source for current facility information, while the court maintains criminal charging and disposition records.

What if the person is in an Illinois state prison?

A person convicted and committed to state custody may be held by the Illinois Department of Corrections rather than DuPage County Jail.

The Illinois Department of Corrections operates a public Individual in Custody Search.

Criminal appeals and subsequent decisions

Where to Search DuPage County Criminal Appeals

Appeals from the 18th Judicial Circuit generally proceed to the Illinois Appellate Court, Third District.

The Third District is based in Ottawa, Illinois, and hears appeals from several judicial circuits, including DuPage County.

Why should you check criminal appeals?

A later appellate opinion may:

• Affirm a conviction
• Reverse a conviction
• Remand a case for another hearing or trial
• Change sentencing-related findings
• Resolve a dispute about criminal record expungement

If a public DuPage criminal docket indicates an appeal, review the appellate result before describing the case as finally resolved.

The appellate opinion is not a substitute for certified copies of the underlying Circuit Court judgment or any later order entered after remand.

Expunged and sealed criminal records

DuPage County Criminal Record Expungement and Sealing

Illinois provides legal procedures for qualifying criminal records to be expunged or sealed.

These procedures are governed by applicable Illinois laws, including the Criminal Identification Act.

Eligibility depends on the particular arrest, charge, disposition, criminal history and statutory exceptions.

Official Illinois expungement forms updated in 2026

The Illinois Courts website provides approved statewide expungement and sealing forms revised in June 2026.

These include:

• How to Clear Your Criminal Record: Expungement and Sealing
• Request to Expunge and/or Seal Criminal Records
• Case List for Request to Expunge and/or Seal Criminal Records
• Additional Arrests or Cases for Expungement
• Additional Arrests or Cases for Sealing
• Order to Expunge and/or Seal Criminal Records

How to begin a DuPage criminal expungement request

1. Collect your complete criminal case history

   Identify qualifying DuPage arrests, court cases and dispositions.

2. Review the legal eligibility requirements

   Determine whether each case may qualify for expungement, sealing or another form of relief.

3. Download the approved Illinois forms

   Use the current statewide standardized forms rather than outdated local forms.

4. Complete the case list and petition

   Include the required arrests, case numbers, charges and dispositions.

5. Submit the petition to the appropriate court

   Follow the 18th Judicial Circuit’s filing instructions and pay the applicable fee or pursue an available waiver.

6. Follow the court’s notice and hearing requirements

   Respond to objections or other court instructions if applicable.

7. Review the final order

   If relief is granted, confirm the terms of the signed order and follow the responsible agencies’ implementation procedures.

DuPage County expungement filing fees

The Circuit Clerk’s published fee book lists $180 for several ordinary adult expungement and sealing petition categories.

Certain juvenile expungement matters and specified pardon-related petitions are listed without a filing fee. Other legally available waivers or special clinic arrangements may affect what an eligible individual must pay.

The Clerk also hosted a free DuPage County Expungement Clinic in September 2026. Its official page confirms the 2026 event has ended and directs interested individuals to watch for information about a future clinic.

Resolve common records-search problems

Why Can’t I Find DuPage County Criminal Records Online?

How do you interpret a criminal court disposition?

Different case events have different legal meanings.

A single DuPage criminal case may involve multiple charges with different outcomes.

For reliable research, identify the final disposition of each charge and any later order that changes the result.

Federal cases are different

Federal Criminal Cases Involving DuPage County

A federal crime committed in DuPage County may be prosecuted in the U.S. District Court for the Northern District of Illinois.

Federal criminal case records are separate from the Illinois 18th Judicial Circuit.

If the matter involves a federal prosecution, use PACER and the appropriate federal court rather than searching exclusively in DuPage County Circuit Court.
