We help you with the implementation of the GS1 system

Here you will find useful tools and information about the barcode and the allocation of GS1 identification keys.

Which GS1 identification keys are available?

GS1 identification keys

The base of all GS1 identification keys is the GS1 base number (GCP, GS1 Company Prefix).

GS1 data carrier

Barcodes are data carriers. They represent information in a machine-readable font. The data is thus recorded quickly and securely.

How does data exchange work?

Exchange data with GS1 standards

When data is exchanged, information is transmitted between computers. Standards are needed to interpret the information.

Global Data Synchronistaiton Network - GDSN

Through the Global Data Synchronisation Network (GDSN), manufacturers and retailers can exchange their product master data worldwide.

EANCOM & GS1 XML

EANCOM and GS1 XML are standards of the GS1 organisations for electronic data exchange. An integral part of both message standards is the GS1 identification system, which uniquely identifies partners and their goods.

How does traceability work?

Application Identifier

The GS1 Application Identifier can be used to encode various information about a product or a pallet in the GS1 barcode.

GTIN & GLN allocation rules

GTIN allocation rules

The GTIN allocation rules help you with uncertainties about how and when a new GTIN must be allocated to a product.

GTIN allocation rules in the health sector

Especially for the healthcare sector, you will find the GTIN allocation rules here. These help you with uncertainties about how and when a new GTIN must be assigned to a product.

GLN allocation rules

The GLN allocation rules help you with uncertainties about how and when a new GLN must be allocated to a site.

SAN - variable-volume fresh products

Label fresh products with SAN

The four-digit standard article number (SAN) identifies variable-measure consumer units from the fresh product sector.
