Check digit calculator & EAN-13 barcode generator

You can either calculate single check digits or several at once. Please make a note of the check digits and save the file containing the generated check digits. GS1 Switzerland does not store the check digits you calculate! The check digit calculator only calculates check digits. It does not check whether you have set up the identification number correctly. Please get in touch if you are unsure of anything. GS1 Switzerland does not accept any responsibility for the check digits. Each user of the GS1 system is personally responsible for calculating the check digits.

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”

GCP must be 7-9 digits and GLN 11 digits long

This value can be freely selected and is today an expansion of the capacity-building SSCCs. GS1 Switzerland recommends using the value '3 '.
The maximum value could not be smaller than the minimum value.
