Global data and application standards for bar codes that use the globally recognized GS1 Identification Keys to automatically identify things such as trade items, locations, logistic units, and assets.

Based on the symbol used to encode data, GS1 barcodes can be categorized into two broad categories:

  • GS1 barcodes with linear/1D symbols which include:
    • EAN/UPC
    • GS1 DataBar
    • GS1-128
    • ITF-14
  • GS1 BarCodes with 2D symbols which include:
    • GS1 DataMatrix (‘2D matrix’ symbol)
    • GS1 composite component (‘2D linear’ symbol - It is called a composite component because it is only used with a linear barcode like GS1-128 or GS1 DataBar)
