Introduction to GS1 Barcodes

In order to use barcodes as a reference number for retail products and in the international supply chain, it is important to have consistent standards - imagine the mess if every manufacturer had to produce different barcodes for Target, Wal-Mart, Kroger, etc.

GS1 is the global entity that sets standards for barcodes and data just about everywhere to keep supply chains working.

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. 

Consequently, this isn’t a technical document about barcode structures - no x-dimensions, contrast, quiet zones (well, not much!)- we are going to discuss how GS1 data is encoded into barcodes for some industry applications and how those barcodes are used as part of a compliant labeling and marking system.

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.
