GSRN (Global Service Relation Number)
The Global Service Relation Number (GSRN) is the GS1 Identification Key used to identify the relationship between an organisation offering services (in this case, any Healthcare provider) and the recipient of services (in this case, the patient). The same Identification Key can be used to identify the relationship between the organisation offering the service and the provider of the service (in this case, the caregiver), but using a different Application Identifier to clearly distinguish the role.
The Application Identifiers (8017, 8018) indicate that the GS1 Application Identifier data field contains a GSRN (Global Service Relation Number).
In comparison, the Global Service Relation Number – Provider (8017) identifies the relationship between an organisation offering services and the provider of services. While the Global Service Relation Number – Recipient (8018) identifies the relationship between an organisation offering services and the recipient of services.
The GSRN is normally assigned by the Service Provider using either Application Identifier (8017) or (8018).
The GSRN - Provider (8017) is constructed as follows:
| Global Service Relation Number (GSRN) - PROVIDER | |||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| GS1 Company Prefix > < Service Reference | Check Digit |
||||||||||||||||
| N1 | N2 | N3 | N4 | N5 | N6 | N7 | N8 | N9 | N10 | N11 | N12 | N13 | N14 | N15 | N16 | N17 |
N18
|
The GSRN - Recipient (8018) is constructed as follows:
| Global Service Relation Number (GSRN) - RECIPIENT | |||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| GS1 Company Prefix > < Service Reference | Check Digit |
||||||||||||||||
| N1 | N2 | N3 | N4 | N5 | N6 | N7 | N8 | N9 | N10 | N11 | N12 | N13 | N14 | N15 | N16 | N17 |
N18
