GS1 Standards

A common language to identify, capture, and share information globally

GS1 Standards are unique identification numbers tagged to an item/product that provide the link between the item and the information pertaining to it. Think of GS1 Standards as the DNA of an item or product moving through the supply chain.

The type of information GS1 Standards provide gives companies a comprehensive picture of inventory in real time. Information may include product attributes, transactional data, and physical location data.

It all starts here – The GS1 Company Prefix

GS1 Identification Numbers are used to uniquely distinguish all products, trade items, logistic units, locations, assets, and relationships in the supply chain—from manufacturer to consumers.

Why Use GS1 Standards?
GS1 Standards allow companies and trading partners to use a “common language” to identify items in the supply chain. This common language allows companies to then identify, capture, and share supply chain information globally. Most importantly, standards enable collaboration with trading partners, an optimized supply chain, and more efficient business processes that reduce human error and cut costs.

Consumers also benefit from GS1 Standards, which can help companies communicate accurate product data electronically, via smart phones and barcode-scanning mobile applications.
