# Identifiers

# Known Facts vs. Identifiers

Once successfully enrolled, to interact with the service, such as filling in and returning a Tax Self Assessment form, only a unique reference to the user's account within the service is required. This is normally a subset of the known facts, called the identifiers (or identifier group). In this example it is the UTR (Unique Tax Reference), since this single item locates the user's account within the service.

The Gateway stores enrolment identifiers against each principal/agent enrolment. Whenever the Gateway routes a transaction message, from a principal/agent to a service, it checks the identifiers supplied by the issuing portal (or application) to ensure the principal/agent has an enrolment in the target service. At the service the identifiers uniquely identify the user within the service.

To conform to data privacy rules, the Gateway does not reveal to services the known facts provided for enrolment to other services.
