A Registration Agency (RA) (formally called Registration Agency Member) can be considered as a module of the DOI System, serving a constituency. New RAs can be added at any time, thereby allowing modular growth of the system by adding new communities of users and providing tailored services for them. A registrant is a person or organization who has requested and received the registration of a particular DOI name.

This section explains the role and function of Registration Agencies in the DOI System, including operational and technical requirements and policies. A list of current Registration Agencies and their areas of coverage is available on the DOI web site.
