Which barcode should I use for pallets?
Pallets are identified using a logistics label containing an SSCC and GS1-128 barcode.
GS1-128 barcode symbols are used with Application Identifiers (AI) to encode various data on a logistics label for a pallet, including an SSCC (Serial Shipping Container Code), the GTIN of the cases or products on the pallet, content count, batch number, and other options.

GS1 Ireland offers an online tool to help you create logistics labels for your pallets.
