Megan's Law
Megan's Law is the federal requirement that gives the public access to information about registered sex offenders. Passed in 1996 as Public Law 104-145, it requires every state to collect specific information, maintain a public sex offender registry, and alert communities when certain offenders move nearby.
The law is named after seven-year-old Megan Kanka, who was abducted and murdered in 1994 by a previously convicted sex offender living in her neighborhood. At the time, her family—and the community—had no way to know that a sex offender lived nearby. Her case sparked a nationwide call for greater transparency in sex offender registry information and ultimately led Congress to enact Megan's Law.
Although the U.S. Department of Justice offers a national search tool through the National Sex Offender Public Website (NSOPW), each state manages its own Megan's Law database with different update timelines and reporting practices. These differences can make it difficult to get a complete picture when conducting a sex offender search.
KidsLiveSafe helps simplify this process by gathering data from federal and state registries into a single interface and offering automatic updates when offender information changes.

What Megan's Law Requires
Megan's Law establishes how sex offender registration and public notification systems operate in the United States. It outlines three major obligations for state and local authorities:
- offender registration
- public disclosure
- community notification
Registration Requirements
Under this federal law, individuals convicted of qualifying sexual offenses must register their personal information with law enforcement. This typically includes their name, current address, place of employment or school, physical description, and details about the offense. Registrants must update this information regularly– within days of moving, changing employment, or altering other key details required by their jurisdiction.
Public Disclosure Requirements
Each state is required to maintain an online database that provides public access to registered offender information. These state sex offender registries vary in design and detail but generally include identifying information, photographs, and offense histories.
Community Notification
Megan's Law also requires law enforcement to notify communities when certain high-risk offenders move into the area. Notifications can include online alerts, mailings, or community meetings.
How Megan's Law Works Across Federal, State, and Local Levels
Although Megan's Law is a federal law, the system it creates is carried out across multiple layers of government. Each level– federal, state, and local– has distinct responsibilities that work together to ensure accurate registration, public access, and community safety.
Federal Oversight
At the national level, Megan's Law is administered under the U.S. Department of Justice through the Office of Sex Offender Sentencing, Monitoring, Apprehending, Registering, and Tracking (SMART Office). The federal role includes establishing minimum national standards, monitoring state compliance, and maintaining the National Sex Offender Public Website (NSOPW.gov), where users can search by name, ZIP Code, location, or ZIP Code.
State Implementation
Each state is responsible for operating its own sex offender registry, verifying registrant information, determining risk levels or classifications, and making required details available to the public. Because states choose their own update schedules, reporting procedures, and website format, information can appear differently across each state sex offender registration system.
Local Agency Responsibilities
Local law enforcement agencies, such as police departments and sheriff's offices, handle the day-to-day registration process. They conduct in-person check-ins, verify addresses, collect photographs and fingerprints, and issue community notifications as required.
What Information Megan's Law Makes Public
Megan's Law requires states to make certain information about registered sex offenders available to the public.
The types of information commonly made available include:
- Name and known aliases
- Photograph and physical description
- Current residential address or general location
- Offense details, such as the nature of the crime and conviction date
- Risk level or classification, when used by a state
- Employer or school information (state-dependent)
- Vehicle information, including license plate numbers (state-dependent)
Not all information collected during registration can be released. States are prohibited from sharing sensitive data such as Social Security numbers, victim identities, and information that could compromise an ongoing investigation.
How to Check Megan's Law Data in Your Area
Because sex offender registry information is maintained separately by each state and aggregated federally, the most accurate way to check Megan's Law data is to use a combination of state resources, federal tools, and verified third-party services. These three steps ensure you're viewing current, comprehensive information.
Step 1: Visit Your State's Megan's Law Website
Start with your state's official sex offender registry. Each state registry is operated directly by law enforcement and updated with jurisdiction-specific information. You can usually search by name, ZIP Code, city, or map. They also provide state-specific updates, risk levels or classifications, and offender photos.
Step 2: Use the National Sex Offender Public Website
The National Sex Offender Public Website is managed by the U.S. Department of Justice and provides a nationwide search tool. It allows users to look up registered offenders across all 50 states, U.S. territories, and tribal jurisdictions.
Step 3: Use a Verified Data Aggregator (KidsLiveSafe)
Verified data aggregators, such as KidsLiveSafe, compile information from federal and state sources into a single, easy-to-use interface. These services often add value beyond public registries, including address-history reports, radius-based mapping, and automatic alerts when an offender moves near a chosen location. For many families, this provides a more consistent and proactive way to stay informed.

FAQs about Megan's Law
These answers cover the most common questions people have when trying to find sex offenders in their area or understand how Megan's Law works.
Why was Megan's Law created?
Megan's Law was enacted in 1996 after the abduction and murder of seven-year-old Megan Kanka. The law was designed to ensure the public has access to information about registered sex offenders living in their communities.
What's the difference between Megan's Law and SORNA?
Megan's Law requires states to provide public access to certain sex offender information.
The Sex Offender Registration and Notification Act (SORNA), passed in 2006, created a uniform national framework for how states must register offenders, classify them, and share data.
In short: Megan's Law ensures public disclosure, SORNA sets national standards.
How often is registry information updated?
Update schedules vary by state. Some states refresh registry data daily, while others update weekly or monthly. For the most current information, check your state's official registry, the National Sex Offender Public Website (NSOPW.gov), and KidsLiveSafe reports.
Can I share Megan's Law information with others?
Yes—Megan's Law permits sharing official registry links for community safety and awareness. However, using the information to harass, threaten, or target an offender is illegal and can result in criminal penalties.
Why doesn't someone appear in the registry even if I know they're registered?
Several factors may explain this:
- Their information has not yet synced to the public website
- They moved to a new jurisdiction that updates on a different schedule
- They have petitioned for removal (state-dependent)
- Their name is misspelled or listed under an alias
- The state does not publicly disclose their tier or offense type
