| ## Principal, Group, and Organization Names You must assign a name to each principal, group, and organization in the registry. Although a principal, a group, and an organization can have the same name, no two principals, groups, or organizations can have the same name. For example, two principals cannot be named smith, but a principal can be named smith, a group can be named smith, and an organization can be named smith. You can assign up to three types of names: primary, full, and aliases. More: Primary Names Full Names Aliases Name Formats ###
