Naperville Police Records Lookup
Police records in Naperville are handled by the Naperville Police Department for incidents inside city limits. Naperville spans two counties, with most of the city in DuPage County and a smaller portion in Will County. The county where the incident took place determines which court system processes any related criminal cases. This page explains how to get police reports from Naperville PD, what role DuPage County plays, and how to run criminal background checks through the state.
Naperville Quick Facts
DuPage County and Naperville Records
Most of Naperville falls in DuPage County. The DuPage County Sheriff's Office is at 501 N. County Farm Road, Wheaton, IL 60187. Their main number is (630) 407-2000. The sheriff handles law enforcement in unincorporated DuPage County, so if an incident happened just outside Naperville city limits but still in the DuPage area, that report sits with the sheriff.
The DuPage County Circuit Clerk manages court records. Their office is at 505 N. County Farm Road, Wheaton, IL 60187. Call (630) 407-8700 for questions. One thing to know: criminal records are not available online through the DuPage Circuit Clerk. You need to go in person or file a written request. This sets DuPage apart from some other Illinois counties that put court records on the web.
The small part of Naperville that sits in Will County would have court cases go through the Will County system instead. Most of the time, though, DuPage is the county you need.
Requesting Police Reports from Naperville PD
Naperville PD handles police records through the FOIA process. The Illinois Freedom of Information Act (5 ILCS 140/) sets the rules. You can submit a written request to the department. Include your name, address, and a clear description of what you want. Give dates, names, and any case numbers if you have them.
The city must respond within five business days. They can extend to ten if needed. If they deny your request, the denial must be in writing and must cite a specific exemption under the law. You have the right to appeal to the Illinois Attorney General's Public Access Counselor.
The ISP FOIA page shown below provides a good example of how FOIA works at the state level. The same basic process applies to Naperville PD requests.
Keep your request narrow. Broad requests take longer and are more likely to hit problems. If you need a specific incident report, ask for that report by date and location.
Fees and Processing Times
Fees follow the state standard. The first 50 pages are free. After that, each page costs $0.15 for black and white copies. Color copies are more. Payment by check or money order.
Most requests get filled within the five-day window. Larger requests or those that need review from the city attorney can take longer. Naperville PD will let you know if there is a delay and give you a new timeline. There is no charge to submit the request. You only pay when the records are ready for pickup or mailing.
If you need records fast, include as much detail as you can. A report number or case number is best. Without that, a date and address usually work. The less the records staff has to search, the quicker you get your files.
Criminal History Checks
Naperville PD does not do criminal background checks. That is a state function. The Illinois State Police Bureau of Identification runs these checks from 260 North Chicago Street in Joliet, IL. Call (815) 740-5160 for details.
The Uniform Conviction Information Act (20 ILCS 2635/) limits public access to conviction data only. Arrest records without a conviction stay sealed. The Criminal Identification Act (20 ILCS 2630/) adds more rules about who can see what.
Name-based checks use the CHIRP system. You register online and search by name and date of birth. For fingerprint checks, find a Live Scan vendor near Naperville. Results go back to the ISP for processing.
Want to check your own record? The ISP Access and Review process costs nothing. You can see what is on your file and dispute errors. This is a good step before applying for anything that requires a background check.
