Privacy is of the utmost concern for the Washington State Twin Registry. We take many approaches to protect the confidentiality of the identity and data of our twin members. When a twin pair joins the Registry, each twin is assigned a Registry ID number. The link between the ID numbers and names and other personal identifiers is kept in a password-protected database residing on a secure, password-protected computer network. Only Twin Registry staff have access to this database.


If publications or presentations result from research done through the Twin Registry, participants are never identified by name or by any other personal data.
