The requirement applies to just about every sex offense, as well as murder, kidnapping and assault crimes for the purpose of committing a sex act. Registration also applies to anyone who is adjudicated a sexually violent predator (Section 290.01) People who are required to register in another state, who are living or working in California are also required to register (Section 290.02) The requirement applies to anyone who has served a sentence of confinement for one of the enumerated offenses since July 1, 1944 (Section 290.03). It also applies to anyone adjudicated a mentally disordered sex offender since July 1, 1944 (Section 290.04). The requirement also applies to people convicted of equivalent offenses in other states, federal or military courts (Section 290.05). The California courts also have the authority to order a defendant to register for any offense not enumerated in Section 290(c) if it is found that the offense was committed for the purpose of sexual gratification. (Section 290.06). Section 290.07 requires offenders to register even if the underlying offense has been dismissed and expunged. Section 290.08 extends the registration requirement to equivalent convictions in the juvenile justice system. 290.09 requires students and employees of institutions of higher learning in the State of California to register if they are convicted of a listed offense.

Sections 290.010 through 290.020 address the procedural requirements of registration.

The remaining sections of the Sex Offender Registration Act, 290.021 through 290.023 address government procedure and applicability.

Collectively, the sections that make up the Act require anyone convicted of a listed offense to register every year on his birthday for the rest of his life. Failure to register is a misdemeanor if the registerable offense is a misdemeanor, and a felony if the underlying offense is a felony.
