Oklahoma Parental /Legal Guardian Address and Phone Registration is a program designed to help ensure the safety of Oklahoma's children. It requires parents or legal guardians of any child living in Oklahoma to register their address and phone number with the state. This information is used to verify the identity of those who are responsible for the care and upbringing of the child. There are two types of Oklahoma Parental /Legal Guardian Address and Phone Registration: online registration and paper registration. Online registration is done through the Oklahoma Department of Human Services website and requires the parent or legal guardian to provide their name, address, phone number, and other contact information. Paper registration is done through a county court clerk and requires the parent or legal guardian to provide their name, address, phone number, and other contact information in person. Both forms of registration are necessary to ensure the safety of Oklahoma's children.
