GS1-128

GS1-128 is the barcode standard used on cases and pallets to encode, besides the product, data such as the lot, the expiration date, the weight or the serial number of the logistics unit.

GS1-128: the details

Each piece of data is preceded by an application identifier in parentheses that says what it is: (01) the product code or GTIN, (10) the lot, (15) the best-before date, (17) the expiration date and (00) the SSCC, the serial number that uniquely identifies each pallet. A scanner that understands those identifiers can interpret any label, whichever supplier it comes from.

It’s what makes it possible to receive goods without typing and to follow a lot along the chain. Big retail requires it on the pallet label, usually together with an EDI ship notice announcing which SSCCs are on the truck. The most common failure isn’t printing but data: a correct label with the wrong lot.

GS1-128 in a project

We generate the labels from production or intake data, with nobody typing it, and verify them when scanned at shipping against the order.
