The Sex Offender Tracking Program at the California Department of Justice (DOJ) maintains the registered sex offender database.
That database is the basis for the information displayed on this Internet web site.
When a sex offender is released into the community, the agency forwards the registration information to DOJ.
Registered sex offenders are required to update their information annually, within five working days of their birthday.
Some sex offenders must update more often: transients must update every 30 days, and sexually violent predators, every 90 days.
The Sex Offender Tracking Program keeps track of the next required update, and if a registered sex offender is in violation of the update requirements, the Internet web site will show the registrant as being in violation.
When registrants change their residence address or suddenly become homeless, they are required to update their registration information within five days with a local agency, which forwards that information to DOJ.
Transients must update their transient location every 30 days with a local agency.
The DOJ updates the registered sex offender database on a daily basis, based on information received from local agencies.
DOJ also updates the registered sex offender information on this Internet web site on a daily basis.
Not every registered sex offender will appear on this Internet web site.
