Sex offender registry is a system in various countries designed to allow government authorities to keep track of the residence and activities of sex offenders, including those who have completed their criminal sentences. In some jurisdictions in the United States, where sex offender registration began, registration is accompanied by residential address notification requirements. In many jurisdictions, registered sex offenders are subject to additional restrictions, including on housing. Those on parole or probation may be subject to restrictions that do not apply to other parolees or probationers. Sometimes, these include (or have been proposed to include) restrictions on being in the presence of minors, living in proximity to a school or day care center, owning toys or other items of interest to minors, or using the Internet. Sex offender registries exist in nearly all English-speaking countries, including the United States, Canada, New Zealand, Australia, South Africa, the United Kingdom, and Ireland. Sex offender registration does not exist outside of the Anglosphere, however. The United States is the only country with a registry that is publicly accessible; all other countries in the Anglosphere have sex offender registries only accessible by law enforcement.
