GS1-128 Barcode Generator (EAN-128)

What is a GS1-128 Barcode?

GS1-128, formerly known as EAN-128 or UCC-128, is a subset of Code 128 that uses GS1 Application Identifiers (AIs) to encode standardized supply chain data. It can contain multiple data fields in a single barcode, including GTINs, expiration dates, batch numbers, serial numbers, and more. GS1-128 is the global standard for logistics unit identification and is widely used on shipping labels, pallets, and cases.

GS1-128 is built upon the Code 128 barcode format, adding GS1 Application Identifiers for standardized data encoding. For 2D GS1 codes, see GS1 Data Matrix or GS1 QR Code.
