Our standards and solutions

GS1 Standards provide a common basis for companies that allow for products, locations, assets, transactions, etc. to be uniquely 

  • identified by a globally unique number 
  • to encode these identification numbers (with additional information) in a data carrier so that this information can be transferred automatically, and 
  • and to exchange the related information between trading partners  

Below you will find an overview of the various standards that GS1 supports and the solutions and applications that are offered based on these standards. 


GS1 identification keys are unique identification numbers that can be used worldwide. These identification keys are generally used to identify the following things: 


What do you want to identify? Which GS1 identification key do you need? 
Trading units/products  GTIN
Logistical units SSCC
(Physical) locations GLN
Discount vouchers GCN
Reusable assets GRAI
Additional information (lot number, expiry date, etc.) Application Identifiers
Other information  Other GS1 identification numbers

Data carriers

All GS1 identification keys can be converted to machine-readable data carriers so that the encoded information can be read automatically. For example, a barcode can be scanned at the checkout.  

There are several types of barcodes and other data carriers in which the identification keys, and potentially additional information, can be encoded.  

The type of data carrier you use will depend on the type and amount of information you want to encode, the scanning environment, the material on which you need to print the data carrier and possibly the requirements of your business partner.
