An adoption registry is a system for matching persons who desire contact with their birth relatives.
Birth Parent and Adopting Family Registries
If your state has a registry, it may be found under the adoption laws of your state. The registry is for any adoptee who is 18 years of age or older, birth parents, siblings and birth relatives, and adoptive parents of an adopted child who are still under the age of 18.
To find the adoption registry in your state you may also want to contact you state child adoption specialist or your state child welfare agency. You may also want to type "Adoption Registry for ----(the state where you were born or gave birth)" into your search engine.
