Global Location Number (GLN)

The Global Location Number can be used by companies to identify their locations, giving them complete flexibility to identify any type or level of location required.

The GLN can identify a company’s physical locations, for example a store, a warehouse, or a berth in a port.

The GLN can be used to identify an organisation as a corporate entity.

The GLN can also identify a company’s legal and functional entities engaging as parties in a particular business transaction, for example as buyer, seller, or carrier.

The GLN extension component can be added to a GLN to provide more precise recording and sharing of supply chain events. For example, an extension component may identify sub-locations such as storage bins, dock doors, scan and read points. Note that master data such as address and contact details can only be associated with The GLN, and not the extension component.

The GLN is encoded in either a bar code or EPC/RFID tag to automatically identify locations like storage places in a warehouse, the destination of a pallet, or the origin of a product.

The GLN can be used in electronic messages and registries to inform trading partners about companies and their corresponding GLNs and associated GLN information.

The GLN is also used by organisations in the public sector. In fact, various applications exist where governments use GLNs, either to identify their own agencies or to identify companies using central government databases.

Note: GLN is fully compatible with ISO standard 6523. The international code designator (ICD) for the GLN is '0088'.
