The GS1 core number (GCP, Global Company Prefix) forms the basis for the GS1 identification key. This includes for example the GTIN (Global Trade Item Number) for products, the Serial Shipping Container Code (SSCC) for logistics units and the GLN (Global Location Number) for locations. These enable unique global identification.
You can only receive GS1 core numbers in Switzerland if you are a member of GS1 Switzerland.
You can find your GS1 core number in your confirmation letter or using GEPIR. You will find information on how to set up GTINs (Global Trade Item Numbers) correctly on “Four steps to the GS1 system”
