The Sex Offender Community Notification Act, at 730 ILCS 152/115, orders the Illinois State Police to keep a statewide Sex Offender Database on the internet of everyone convicted of the listed sex offenses and crimes against children who must register, and the State Police offender registry is that database, run by the Offender Registration Unit beside the Murderer and Violent Offender Against Youth Registry and the Missing Sex Offenders List. A person lands there after a charge under 730 ILCS 150/2(B) or 2(C) ends in a conviction for the offense or an attempt, a finding of not guilty by reason of insanity, or a finding short of an acquittal, and the State Police is explicit that it has assessed nobody's risk of re-offense before listing them, that inclusion rests solely on the conviction record and state law, and that the purpose is easy access to public information rather than a warning about any particular person. The search asks first for a type, Sex Offender, Murderer and Violent Offender Against Youth, Homeless, Incarcerated, Out-Of-State or Missing, then takes a first name, last name, date of birth, city, ZIP Code or one of the 102 counties, a status of compliant, non-compliant or location unknown, and an offender type of child sex offender, adult sex offender or murderer, and a Download All button hands over the whole list.
Registration itself happens locally: a registrant who lives inside city limits registers with the city police department and one in an unincorporated area with the county sheriff, and that registering agency is the one that answers questions about the duty to register, extensions and the ending date, corrects a wrong record and verifies the residence in person at least once a year. The Offender Registration Unit answers at ISP.SOR.Unit@illinois.gov, decides equivalencies for people arriving from other jurisdictions and imposes the administrative extensions. The State Police warns that the registry covers only the registrable offenses and never the whole criminal history, which its Bureau of Identification supplies, that the current residence or status may have changed since the registrant reported it, and that harassing, stalking or threatening a registrant or the registrant's family may break Illinois criminal law; the police department or sheriff for every address is on the Illinois county pages.
- Search: the State Police registry by name, date of birth, city, ZIP Code or county, filtered by status and offender type, with homeless, incarcerated, out of state and missing searches and a download of the whole list.
- Duration: ten years with an annual in person registration for a sex offender, life for a sexual predator or a first degree murder registrant, and every 90 days for life for a sexually dangerous or sexually violent person; a violation adds ten years.
- Fees and changes: $100 at the first registration and $100 a year; any change reported within three days to the city police or the sheriff, and anyone staying three or more days in a year at an address registers it.
- Child sex offenders: no residence within 500 feet of a school, playground or facility serving only minors, no presence on school grounds or within 500 feet without permission, and no entry to a public park since January 1, 2011.
Written by SearchSystems.net from Illinois's own systems: the Illinois State Police offender registry search page, the Illinois State Police offender registry frequently asked questions, the State of Illinois service page for locating registered sex offenders, each read on October 14, 2026 by the SearchSystems editorial team.
Who registers in Illinois
The State Police questions page lists the convictions and adjudications, felony or misdemeanor, that require registration: indecent solicitation of a child, sexual exploitation of a child, soliciting for a juvenile prostitute, keeping a place of juvenile prostitution, patronizing a juvenile prostitute, juvenile pimping, exploitation of a child, child pornography and aggravated child pornography, criminal sexual assault, aggravated criminal sexual assault, predatory criminal sexual assault of a child, criminal sexual abuse and aggravated criminal sexual abuse, ritualized abuse of a child, forcible detention of a victim under 18, indecent solicitation of an adult, soliciting for a prostitute, pandering, patronizing and pimping when the victim is under 18, a third public indecency conviction, custodial sexual misconduct for convictions on or after August 22, 2002, sexual misconduct with a person with a disability, permitting the sexual abuse of a child, kidnapping, aggravated kidnapping, unlawful restraint and aggravated unlawful restraint of a victim under 18 by someone other than a parent when the offense was sexually motivated and committed on or after January 1, 1996, sexually motivated child abduction by luring a child under 16 into a vehicle or building, first degree murder of a child under 18 by a defendant of at least 17, first degree murder of an adult for anyone released from the Department of Corrections on or after January 1, 2002, and any attempt at the offenses above.
A finding of not guilty by reason of insanity, a finding short of acquittal, a substantially equivalent conviction under federal, military, another state's or a foreign law, a juvenile adjudication for any listed offense and an adjudication as sexually dangerous or sexually violent all count too.
A sexual predator is someone convicted after July 1, 1999 of keeping a place of juvenile prostitution, juvenile pimping, exploitation of a child, child pornography or aggravated child pornography, criminal sexual assault of a victim under 12, or of any victim for convictions on or after January 1, 2006, aggravated criminal sexual assault, predatory criminal sexual assault, aggravated criminal sexual abuse or ritualized abuse of a child, of sexual misconduct with a person with a disability or the kidnapping, restraint and child abduction offenses for convictions on or after January 1, 2011, of a sexually motivated first degree murder of a child, or of a second registrable offense after July 1, 1999, plus anyone certified sexually dangerous or found sexually violent and anyone with an equivalent conviction elsewhere.
Public Act 97-0578, effective January 1, 2012, added retroactive registration: a person never before required to register, or who completed a ten year period for an offense that now carries more than ten years, must register after any felony conviction after July 1, 2011, and anyone moving to Illinois on or after January 1, 2012 while required to register in another state is a sexual predator with lifetime registration, due within three days of arrival; someone who moved in earlier registers when the out of state offense is substantially equivalent to an Illinois one, for ten years or life as that offense dictates.
Ten years, annually, or life
A sex offender registers in person once a year for ten years, counted from conviction for a probation sentence and from final parole, discharge or release for a sentence to the Department of Corrections, another state's prison or federal custody, re-registering within a year of the last registration each time and reporting any change within three days; when the ten years end the record leaves the website. A sexual predator registers once a year for natural life, as does anyone registered for first degree murder, and a person adjudicated sexually dangerous or sexually violent registers every 90 days for life, a pace also imposed on anyone convicted on or after July 1, 2005 of violating the Registration Act, for the rest of the registration.
The period grows through administrative ten year extensions, convictions for violating the Act, later sex offense convictions, time tolled while in the Department of Corrections and new felony convictions that trigger the retroactive lifetime rule. The State Police extends the period by ten years from the first registration after any failure to comply, sending a registered letter to the registering agency within three days that the registrant must sign for; the registrant has ten business days to petition the State Police to review the circumstances, the State Police acts within 30 days, either removing the extension and issuing a new ending date or sending a request for hearing form that must be returned within 30 days, after which an administrative law judge hears the case, recommends a decision within 90 days of the hearing and the Director rules within 30 days of receiving the record, subject to the Administrative Review Law.
Where to register, the fees and moving
The first registration costs $100 and each annual registration $100 more. A registrant must register every place lived for three or more days in a calendar year, and a move is reported within three days both to the agency where the person lived and to the agency where the person is moving. A visitor from another state who spends more than three days in Illinois in a calendar year, cumulative rather than consecutive, registers with the local agency where staying, and a registrant leaving Illinois for a vacation or for work tells the registering agency first, gives an itinerary for work travel, may need to report an address change after more than three days in another jurisdiction and, for a trip abroad, triggers notice to the National Sex Offender Targeting Center.
The law lets the State Police list transitional housing facilities licensed by the Department of Corrections, and the questions page records that none exists.
The child sex offender rules: schools, parks and homes
An adult convicted of an offense against a victim under 18 is a child sex offender under 720 ILCS 5/11-9.3, and the residence, park and school rules fall on that person; a juvenile adjudicated delinquent carries none of them at any age. A child sex offender may not live within 500 feet of a school, playground or facility providing programs or services only for people under 18, measured from the nearest point of the school's property line to the residence's property line, or from the playground's line to the edge of the residence, unless the offender owned the property before the date the statute sets; may not be present in a school building or on school property or loiter within 500 feet of it without permission from the superintendent or school board, or the principal of a private school, except as the parent of a pupil attending a conference on the child's progress, a special education placement meeting or a retention or promotion conference; and, since January 1, 2011, may not knowingly be in a public park building or on any public park, forest preserve or conservation area land, a Class A misdemeanor that also binds sexual predators, with exceptions for convictions under two criminal sexual abuse provisions.
Nothing in Illinois law stops a child sex offender from being around children elsewhere, but a parent or guardian who knowingly leaves a minor in the offender's custody or control or gives unsupervised access commits a Class A misdemeanor unless the offender is the child's parent, was convicted under one sexual abuse provision or is married to and living with the parent, and the offender must report within three days of starting to live in a household with someone else's child under 18; the Department of Children and Family Services hotline at 800-25-ABUSE takes a welfare concern.
Schools learn who is nearby because the State Board of Education sends school addresses to the State Police each quarter and the sheriffs pass registrant lists to public school boards and private school principals, with the Chicago Police Department doing it in Chicago.
Statuses: compliant, non-compliant and location unknown
A registrant becomes non-compliant by failing to register within three days of notice from the Department of Corrections or the court, failing to register annually or quarterly, giving incomplete or false information, or changing an address or other information without notice. Location unknown means the person left the last reported address, the police confirmed it by a physical check, no new address was given and the person is missing as well as non-compliant; the questions page suggests asking the local Crimestoppers organization whether a reward is available for the whereabouts of a missing sex offender, with no guarantee from the State Police.
Every registration produces a new photograph under 730 ILCS 150/3, uploaded to the record and published, so a missing photograph is a question for the registering agency. A person registered only for first degree murder of a child, kidnapping, aggravated kidnapping, unlawful restraint, aggravated unlawful restraint, child abduction or forcible detention may move to the Murderer and Violent Offender Against Youth Registry once the State's Attorney of the county of conviction certifies on the State Police form that the crime was not sexually motivated and the form reaches the registering agency and the Offender Registration Unit, a step the offender must initiate, even for a military, federal or out of state conviction.
Victims, court files and the rest of the record
A victim who wants to follow an offender's custody and court status registers with Illinois VINE, which the Attorney General's office promotes as a free and confidential service drawing on county jail bookings, the Department of Corrections, the Department of Human Services and the circuit clerks, with notice by email, text, telephone or app. More about an offense than the website shows comes from the circuit clerk of the county of conviction, who copies the court file, and the criminal history record is available under the Uniform Conviction Information Act.
Anyone who believes a record on the site is wrong reports it to the registering agency, and a registrant in another state is found through that state's registry or the national public website.
Reading an Illinois result
A record names the registrable offense, the status and the registering agency, with a photograph taken at the last registration and an address that may have changed since; a sexual predator, a murderer or a sexually dangerous or violent person stays for life while a ten year registrant leaves the site when the period ends, and the city police or the sheriff that took the registration holds the file, the ending date and any extension.
