A unique identifier is how your domain or organisation is identified to service providers when users access resources. They are either Whilst occasionally a numeric organisation ID or they are more usually a scope depending on the service provider and this looks like an internet domain - e.g.

Each domain will have a unique identifier and that is usually all that is needed - i.e. all subscription content is purchased for the whole domain.

Sometimes a domain is very large or widespread and has different resource needs for the organisations within it - e.g. sites in different countries. Where this is the case, the organisation can be set to have its own unique identifier and this allows the users under of that organisation to be seen by service providers as being represented by a different subscription. Specifically they will have their own organisation ID and scope - they but will still use the same federation entityID as the domain.


  • Content associated with the domain's identifier cannot be accessed by users under an organisation with its own identifier unless the service provider is able to associate multiple identifiers with an institutional or enterprise a subscription.
