Barcodes are used to encode information such as key identifiers (product, shipment, location, etc) and key attributes (serial numbers, dates, batch lot numbers, etc) with GS1 symbols & standards that have been revolutionised across the globe for over 50 years.
They play a key role in supply chains, enabling parties like manufacturers, suppliers, distributors, retailers & hospitals to automatically identify & track products as they go from source to sale within SA and around the world.
GS1 utilises several types of barcodes to satisfy different business requirements.

Linear Barcodes

Linear barcodes, like the UPC, EAN, DataBar, GS1-128 & ITF-14 are commonly found on consumer goods. They use a series of lines and spaces to encode data, and include GTINs for product identification.

Two Dimensional Barcodes

Two dimensional barcodes use patterns of squares, dots and other shapes to encode data, because the data has a 2D pattern, these barcodes can hold more data than 1D barcodes while still appearing physically smaller. They’re used in a wide range of industries, from manufacturing & warehousing to logistics & healthcare.

GS1 DataMatrix

Compact 2D barcodes that holds a lot of data in a small space, can be used across industries. They identify very detailed product information, for example healthcare & grocery products.

GS1 QR Codes

Square 2D barcode that carries text-based data, designed to be read by scanners & smartphones. Represents a URL & a GTIN on a product or item.

GS1 DotCode

Barcodes that meet requirements of the EU tobacco traceability regulation - EU 2018 / 574.

Note 1: GS1 DataMatrix & QR Codes are both encoded with GS1 Digital Link URI or element string syntax.

Note 2: For regulated healthcare trade items GS1 DataMatrix is the only allowed 2D barcode.
