1D Barcodes
One dimensional barcodes are also called linear barcodes. They are commonly found on consumer goods and use a series of variable-width lines and spaces to encode data, including the GTIN for product identification.
EAN-8
This encodes a GTIN-8, which is allocated directly by GS1 Australia or any other GS1 organisation. EAN-8 barcodes are used on small packages where the EAN-13 barcode would be too large.
Examples of use: small retail items like cosmetics

EAN-13
This encodes a GTIN-13, and is used to identify the vast majority of trade items in the retail supply chain.
Examples of use: retail items that cross Point-of-Sale applications, like cans of soup, clothes, magazines, books.
This encodes a GTIN-12, and is used to identify some products being exported to North America.
Examples of use: retail items that cross Point-of-Sale applications

UPC-E
This encodes a GTIN-12, but uses a zero-suppression method to compress into an 8-digit format for use on smaller packages. These are also used to identify some products being exported to North America.
Examples of use: small retail items like cosmetics, chewing gum packets

ITF-14 Barcodes
This encodes a GTIN-12, GTIN-13 or GTIN-14. Use this to identify items not intended for Point-of-Sale scanning such as cases and cartons.
Examples of use: product groupings such as a case of washing detergent or a carton of tissue boxes. Its simple design makes it easy to print on the type of packaging used for cartons.

GS1-128 Barcodes
Use GS1-128 barcodes on cases and cartons, pallets and other logistics units in the supply chain; and capture additional information about your trade items. This barcode is not scannable at Point-of-Sale.
The GS1-128 barcode enables companies to capture more information in a single barcode. Initially used in the food and grocery industries, it is now widely used in logistics and other application such as the identification of assets.
The barcode uses a series of GS1 Application Identifiers to include a range of additional data such as:
Best Before Date
Batch Number
Quantity
Weight
The GS1-128 also encodes the SSCC, used for the identification of logistics units.
