GS1 Standards

GS1 Standards form the foundation for efficient supply chains and increase efficiency in goods, information and value flows. You can use them, for example, to give products, sites and logistics units a unique global identification. You can then record that information with standardised data carriers, such as GS1 barcodes or RFID tags and share them easily with your trading partners.

In the age of Industry 4.0, digitalisation brings production, logistics and sales closer and closer together. In the future, machines and product components will have to communicate with each other globally, independently, fluently and efficiently via computers. That creates vast amounts of data. The fact is, nothing works without standards. For more than 40 years, the global GS1 community has been successfully developing principles and solutions for standardised economic processes. A common language is important when it comes to applying them.

GS1 – The Global Language of Business

This common language was first used successfully in the consumer goods industry. But GS1 Standards are not limited to consumer goods: GS1 is sector neutral and not bound to the interests of one single industry. The GS1 system is, therefore, designed in such a way that it can be used in any sector of the economy and in any industry. It applies in particular to the transport and logistics sectors, technical industries or even healthcare. Changes are decided together with the users and introduced in such a way that there is no negative impact on pre-existing implementations.



The GS1 identification keys (e.g. GTIN, GLN) are clearly defined strings of characters of fixed lengths which enable unique referencing in IT systems of physical units such as trading units, transport units, reusable transport containers, sites and service relationships.



To read GS1 identification numbers and other information such as expiration date or batch or serial number automatically, and therefore quickly and accurately, specific data identifiers (AI) and standardised data carriers are used.



GS1 Standards for data interchange determine how information can be used jointly over the entire network of a supply chain. They provide the basis for electronic business transactions and create transparency by linking the digital world with the real worldlt.


Master data



All the standards defined by GS1 can be used individually or in combination to ensure the best possible increase in efficiency and reduction in costs in the respective business processes. What is more, they enable you to meet legal requirements, such as traceability and transparency.
