It has been a mandatory requirement in Colorado for convictions for committing a sexual assault or similar crime on or after July 1, 1991. Generally, the convicted offender receives a notice from a parole officer, judge, probation officer to register himself/ herself in the database. The notice may also be sent from county jails, the Department of Human Services, law enforcement offices, the Department of  Corrections or  community corrections.

Once you are registered in the database of sexual offenders in Colorado, you are required to personally visit the law enforcement agency in the area of your residence. Post-registration, the public will be notified of your name and address. Your date of birth, aliases, likeness and details of the unlawful behavior that led to the registration being ordered will also be made public. All of this information will be put up on a local website so that the public can easily and quickly access it. These requirements are in place to ensure that the society is safe from sexual predators and convicted offenders who have indulged in sex crimes. For you, the convicted person, this public disclosure of your personal data and convictions can have some very serious consequences on your personal and professional life.
