It is the key to accessing information, stored on computer systems, relevant to service(s) provided and received and in some cases, these services could be recurring.
Individuals may be both service providers or clients of an organisation. The GSRN can identify both of these roles uniquely to allow the two roles to be distinguished, enabling them to be captured or recorded within the same IT solutions if needed. An example of where this may occur is a nurse in a hospital who may also be a patient of the same hospital.
The GSRN can be encoded in a barcode or EPC/RFID tag; for example, in a badge or wristband.
The GSRN can be electronically used as a “key” in service registers, dossiers, medical files, invoices, and others.
If there is a need to further identify service encounters of a particular service recipient or provider, the Service Relation Instance Number (SRIN) may be added to the GSRN; for example, to identify the episode of a medical treatment for a patient.
