All domain names have a registrant contact (these are sometimes referred to as accounts throughout this documentation and in field names) associated with it. Registrant contacts are created automatically when a domain is registered if an existing contact is not specified. The ID of the new contact is returned to allow later manipulation.

There are a number of constraints on account objects:

• Once a registrant contact is created the registrar cannot change the organisation name.  This can only be requested by the registrant.
• All the domains associated with a registrant contact must be on the same TAG.  This means that a registrant that has domains with more than one registrar will have multiple contacts.

Modifying registrant contact objects

Registrant contacts can be modified in one of two ways:

• Using the account MODIFY operation by specifying the id(s) of the  object(s) to change.
• Using the MODIFY operation and specifying a domain on the contact to be modified.
