Sex Offender Registry and Sex Offender Registration Laws

A sex offender registry is a government system that requires people convicted of specified sex offenses to provide identifying and other information to authorities, with some information often made publicly available. Federal and state law governs registration requirements, which can differ significantly by jurisdiction.

A sex offender registry is a government database containing information about people who are legally required to register because of specified criminal convictions.

Registration can require a person to provide information concerning residence, employment, schooling, identifying characteristics, vehicles, photographs, and other information established by law. Registrants can also be required to update that information and periodically verify it with authorities.

The duration and frequency of registration vary according to federal and state law.

What Is SORA?

The abbreviation SORA, often meaning Sex Offender Registration Act, is used in some states for their own sex offender registration statutes.

There is no single federal statute universally known as “SORA” that governs every state registry.

What Is SORNA?

The principal federal law is the Sex Offender Registration and Notification Act, or SORNA, enacted as Title I of the Adam Walsh Child Protection and Safety Act of 2006. Federal law establishes registration and notification standards for states, territories, the District of Columbia, and participating tribal jurisdictions.

SORNA establishes federal standards concerning who must register, what information must be collected, where registration is required, public notification, verification requirements, and registration periods.

Under the federal framework, qualifying registrants generally must keep their registration current in jurisdictions where they reside, work, or attend school.

SORNA also uses a three-tier classification structure. Tier I, Tier II, and Tier III classifications carry different minimum registration periods and verification requirements.

State systems do not necessarily use precisely the same terminology or classification method. A person's obligations therefore depend on the law governing the particular jurisdiction as well as any applicable federal requirements.

What Information Is Included in a Registry?

Registry laws can require information such as a registrant's name, residence, employment, school enrollment, photograph, identifying information, and details concerning the qualifying conviction.

Federal SORNA also requires jurisdictions to maintain public sex offender registry websites containing specified information and to participate in the national public registry system.

Not every piece of information collected by authorities is necessarily made public.

Can Registration Apply to an Older Conviction?

Sometimes.

Retroactive application of registration requirements has produced substantial constitutional litigation.

In Smith v. Doe, the U.S. Supreme Court held that Alaska's registration statute could be applied to people convicted before the law was enacted because the Court considered that particular statutory scheme civil and nonpunitive rather than additional criminal punishment.

The constitutionality of another registration law can depend on the specific statute and its effects. Federal and state courts have considered challenges under the Ex Post Facto Clause and Retroactive LawThe Ex Post Facto Clause prohibits federal and state governments from retroactively creating criminal liability or increasing punishment for conduct after it occurred. A retroactive law changes the legal consequences of earlier conduct or events, but not every retroactive law is an unconstitutional ex post facto law.Read more →, due process protections, the Eighth Amendment, and state constitutional provisions.

How Long Does Registration Last?

There is no single registration period applicable throughout the United States.

Under federal SORNA standards, Tier I registration generally lasts 15 years, Tier II registration lasts 25 years, and Tier III registration generally lasts for life. Federal law provides limited reductions in certain circumstances.

State law can classify offenses differently or impose different registration requirements consistent with the jurisdiction's legal framework.

Why Sex Offender Registration Laws Matter

Registration obligations can continue long after incarceration, probation, or parole has ended.

They can affect where and how a person must report information, how frequently information must be verified, what information is publicly available, and how long the obligations continue. Failure to comply with applicable registration requirements can also create separate criminal liability.

Because the laws vary substantially across jurisdictions and have changed repeatedly over time, determining a person's obligations often requires examining the offense, date of conviction, applicable federal and state statutes, and subsequent amendments.
