Types of codes
The type of code you need depends on what you want to code: products, locations, despatch units or something else?
GS1 codes themselves are meaningless, sequential numbers which do not contain any classifying data. They only acquire significance once you assign them to something (and record and share this with your trade partners).
Which codes are available?
Most widely used:
The 13-digit code (or EAN-13, GTIN-13) is most widely used.
This allows you to code your products (and locations as well).
Coding locations: GS1 location code
A location code is also called GLN (Global Location Number).
You can assign a location code to an internal location (e.g. a warehouse rack or conveyor belt) or an external company location (e.g. in case of various branches of your company).
GLNs are the 'key' for retrieving information from databases. The associated name, address information and other data are linked to this unique number.
Shipping goods: GS1 despatch code
The GS1 despatch code, Serial Shipping Container Code (SSCC), is a unique coding for shipments.
This code is assigned to a shipment and expires as soon as the shipment reaches its destination and the pallet is destacked.
