Registration is free and allows you to access all unrestricted online data in our datasets, as well as restricted data for which you meet additional eligibility requirements. When you submit registration information and sign in to our website, your information is encrypted and sent in secure mode.

The personal data that you provide to the RDA below is necessary to register you as a user in our system, and is used only to identify you as a user of RDA data services, so that you can navigate the RDA with more ease and so that we can email you about data updates and any problems discovered.
