GS1 Identification Key Series - GSRN (Global Service Relation Number)
1.
Definition of a GSRN
‘The Global Service Relation Number (GSRN) is the GS1 Identification Key used to
identify the relationship between a service provider and service recipient.’
Global Service Relation Number is the GS1 key to identify a service relationship between a business
and a client. GSRN is a simple tool to identify this relationship. It can identify business relationships
between businesses or individuals. It does not identify a business or individual specifically for
purposes other than the service being provided and therefore does not raise privacy concerns.
In simple terms a company or business will issue a GSRN to a customer to identify their relationship.
This could be a club membership, a member of a Loyalty scheme or to identify a patient attending
hospital. The GSRN will be the key that links to a database to identify the specific detail of the service
offered and the contract with the individual. The GSRN may be held as a database record and may be
encoded in a barcode that the customer may use to identify themselves to the service provider.
The GSRN may be encoded in a GS1-128 bar code, or held in a GS1 EPC tag or used in a database.
The function of a GSRN is to provide an identification point which can be used to retrieve information
held in a database associated that particular service relation.
1.1.
Key GSRN attributes
The GSRN will identify each service relationship individually thus ensuring that it is always identified
correctly anywhere within a business or the world. An individual may have many GSRN’s from
different service providers. As it is the service provider that allocates the GSRN there is no danger of
the individuals other service relationships being linked. The GSRN itself has no meaning and this
allows the service to be looked-up in a secure database and its associated information retrieved only
by the service provider. As it is based on the GS1 system using a GS1 Company Prefix and a serial
number allocation of numbers is simple and uniqueness guaranteed.
If you are a business that has service relationships with individuals and you want to be able to identify
your customers accurately GSRN is a simple tool to enable this.

GSRN Applications
GSRN can be used in business where identification of recurring services is required. This can occur in
many different ways but typically is where the detail of a service sold or offered to a specific customer
needs to be recorded in a database. The GSRN is the key to identify that particular service relation.
Applications can then be developed to utilise further benefits from the use of GSRN by taking the
option to encode the number in a GS1-128 bar code or GS1-EPC tag.
Further applications may be to identify a ‘member’ of a loyalty program on a membership card that is
scanned when the customer needs to be identified.
Alternatively the GSRN may be used to identify the member of a Library. In this instance the Library
records can be updated to the correct member when the GSRN on the card is scanned.
In a hospital the GSRN may be used to identify a patient. If the GSRN is recorded on a wristband then
whenever the patient receives a service from the hospital, the patient’s records can be updated. There
is also a benefit in developing the application to ensure that the patient receives the correct treatment
or drugs by use of the GSRN.
