Photographs and official records
Matches come back as people, not rows — the registry photograph, date of birth, addresses and offense, with a link to the official Illinois record so you can verify at the source.
The whole country in one search
People move. One search here covers Illinois and every other US registry at once, so a registration in Indiana and Iowa shows up on someone now living in Chicago.
Every search, kept
Each check is stored with the results you saw — an audit trail you can reopen, share with teammates, and stand behind later. Upload a CSV to screen a whole list in one pass.
What the Illinois sex offender registry shows you, and what it leaves out. Knowing both keeps a search useful and fair.
What a Illinois registry search shows
- The person's registry photograph, name and any other names they use
- Their age, and their date of birth as Illinois publishes it
- Home, work and school addresses, each labelled
- The offense they were convicted of, and when
- Their risk level and whether they are keeping up with registration
- A link to the official Illinois State Police Sex Offender Registry entry so you can confirm it
What it cannot tell you
- Whether someone is safe. The registry lists a conviction, not a prediction
- Anyone who was never convicted, or whose requirement has ended
- Other criminal history. For that, see Illinois criminal records
- A reason to harass anyone. Using registry information to threaten someone is a crime

Searching the Illinois state site vs searching here for Illinois sex offenders. Both are free to start; here is what is different.
Illinois's own public search is Illinois State Police Sex Offender Registry — free, official, and the right place for a one-off look at a single state. Illinois runs two rosters behind one search form — the sex offender registry and the violent-offender-against-youth registry — and a reader has to notice which list a result came from. Here is what changes when you run the same search here instead.
| On the Illinois state site | Searching here | |
|---|---|---|
| Coverage per search | Illinois only. A registration in any other state never appears. | Every US registry at once — the 50 states, DC and the territories. 58 registries in one search. |
| Your search history | Nothing is saved. Checking the same person next month means starting over, with no record you ever looked. | Every search is stored with the results you saw — a real audit trail you can reopen. |
| Narrowing a common name | Whatever the search form offers, one attempt at a time. | Date of birth, age give-or-take, city, ZIP, street address — and misspellings caught when you want them. |
| Checking a whole list | One name at a time, by hand. | Upload a CSV and screen everyone in one pass. |
| Working as a team | No accounts, so no way to share what has been checked. | Add teammates to one workspace with a shared history. |
| Building it into your product | No API. | A full REST API on the same data, when you are ready for it. |
| Near your address | A map you search area by area. | A free count of the registered sex offenders near your address, then everyone near it with photos on a map for $9.99 once. |
| Alerts | No alerts. You check again yourself. | Family Watch: up to 3 addresses, an email when someone registers, moves in or moves out near any of them. $34.99 a year, cancel any time. |
| Confirming a match | You are already on the official record. | Every match links straight to its official Illinois State Police Sex Offender Registry entry. |

Illinois sex offender search coverage: the Illinois dataset, specifically. What a search here covers.
| Scope | Illinois is in every search by default, and one setting narrows to it alone — in the dashboard a dropdown, in the API jurisdictions: ["IL"]. |
|---|---|
| Date-of-birth matching | A date-of-birth criterion in Illinois resolves at full-date precision and returns dob_match. Match strength is a label on every record — dob_match — rather than a yes or no, so you set your own threshold. 39 of the 56 jurisdictions we cover resolve it the way Illinois does. |
| Best criteria to send | Send dob whenever you hold one — it is accepted in Illinois exactly as it is everywhere else, and it narrows rather than filters, so a record with thinner birth evidence still comes back on the name. In Illinois it is the strongest single narrowing criterion available, returning dob_match. |
| Location search | Narrow to a Illinois city or ZIP, or search a radius of up to 100 miles around a point. Addresses come back as typed entries — residence, secondary, employment, school — so a work address in Chicago is distinguishable from a home address. |
| Freshness | Continuously updated, so a Regular result is close to live, and every record returns the date it was last checked. |
| Verification | Every Illinois match links to the person's official entry on Illinois State Police Sex Offender Registry, so any record can be confirmed at the official registry before you act on it. |
Registry data is not a consumer report, and decisions made on it are regulated in that use.
Illinois sex offender registry and its neighbors: how Illinois behaves next to the jurisdictions around it. People move, so one search covers the neighbors too.
Registration follows the person, not the state line, so screening that covers Illinois almost always has to read Indiana, Iowa, Kentucky, Missouri and Wisconsin in the same breath. One search here covers every row at once.

Illinois offender search FAQ. Short answers before you search.
How many registered sex offenders are there in Illinois?
Approximately 44,200 people are on the Illinois register. It is a population that moves continuously — people are added, reclassified and released from the requirement every week — so treat the figure as scale rather than as a fixed number, and run a search when you need an answer about a specific person.
Should I search Illinois's official registry site or here?
Illinois State Police Sex Offender Registry is free and covers Illinois. Searching here covers Illinois and every other US registry in the same search, keeps a stored history of every check you run with the results you saw, narrows by date of birth, age, city, ZIP or street address, takes a whole CSV list at once, supports teammates on one workspace, and has a full API behind it. If you check people more than once, or people who may have lived anywhere else, that is the difference that matters.
How do I search Illinois sex offender records by name and date of birth?
Type a last name and add whatever else you hold — first name, date of birth, city or ZIP. In the dashboard that is a form; through the API it is one request with jurisdictions: ["IL"] to scope the answer to Illinois. Send dob whenever you hold one — it is accepted in Illinois exactly as it is everywhere else, and it narrows rather than filters, so a record with thinner birth evidence still comes back on the name. In Illinois it is the strongest single narrowing criterion available, returning dob_match.
Does a Illinois search include people registered in other states?
It does when you let it. A search with no state scope runs across every US registry in one pass, which is how a prior registration in Indiana and Iowa surfaces on someone now living in Illinois. Scoping to Illinois narrows deliberately to the IL roster — the two are one setting apart, and every response reports which registries answered.
What does a Illinois record contain?
Every IL record returns under the same normalized shape as the other 57 jurisdictions: identity and aliases, birth evidence with its precision stated, physical description, typed addresses, offense and conviction detail, tier or risk level, registration and compliance status, photographs newest-first, and match scoring on every record. One integration — or one dashboard — reads all of them.
Can I search Illinois by city or ZIP code?
Yes. Narrow to any Illinois city or ZIP, or sweep a radius of up to 100 miles around a point. Addresses come back as typed entries — residence, secondary, employment, school — so a work address in Chicago reads differently from a home address, and each entry carries its own city, county, ZIP and coordinates where geocoded.
How current is a Illinois result?
The dataset is continuously updated, so a Regular result is close to live — and when a decision needs a current, moment-of-decision check, a live block re-verifies the named jurisdictions at the source in the same request. Every record returns its own lastCheckedAt, so currency is a value you read off the response rather than a claim you take on trust.
