The GSRN or Global Service Relationship Number is used to identify the recipient of a service. A GSRN enables a service provider to store data relevant to services provided to a recipient. For example, the GSRN can be used for patient identification enabling a hospital to store information about the medical treatment they have received.
GSRNs are fixed length 18 digit numbers composed of a GS1 Company Prefix, a Service Reference Number and a Check Digit. The GSRN is normally assigned by the service provider and may be bar coded using Application Identifier (8018).
The GSRN is constructed as follows:
|GS1 Company Prefix > < Service Reference||Check|
