An Introduction to GS1 Barcodes

GS1 Barcoding GuideGS1 is the global entity that sets barcode and data standards that make supply chains work. While we tend to think of GS1 in terms of barcodes, the whole GS1 concept is really built around the data – barcodes are just a convenient way of keeping the data where it needs to be and to provide a way it can be captured automatically when needed. RFID is another way of carrying GS1 data. When it comes to barcoding for the GS1 system, the definitive source of information is GS1 itself. When implementing a GS1 compliant system, it is always wise to check everything against the actual specifications.

When you want to sell your product, you need to uniquely identify your brand in the global supply chain. To do this, you might use a barcode, a GS1 Company Prefix, a Global Trade Item Number® (GTIN®), a U.P.C., or a GTIN-14. But what does this all mean?
