What is a GLN?

Powered by GS1 Standards, the Global Location Number (GLN) is best described as a “location barcode.” It helps you track your products’ location throughout the supply chain and uniquely identify the locations involved in its business transactions. These locations can include legal entities, functional groups, digital parties, and physical locations such as a warehouse.
