# III. Registry Users There are three main types of registry users: **Company Representatives (CR)** The company representative is a user with the administrative role of setting up their company on the registry, creating and managing the company's accounts, and inviting other users to serve roles for those accounts. **Account Representative (AR)** An account representative is a user that performs the day-to-day operations on SAF certificates held by registry accounts. ARs are invited to join accounts by a CR working for the same company. {% hint style="info" %} A CR can also serve as an AR for one or more accounts. {% endhint %} **Registry Administrator (RA)** The registry administrator is a 'superuser' on the registry charged with overseeing all aspects of the registry to ensure the smooth operation of the platform. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
