What is the Global Location Number (GLN) used for?

The Global Location Number (GLN) is primarily used for identifying physical locations or legal entities within the global supply chain. This unique identifier facilitates communication and transaction processes between trading partners by ensuring that locations are specifically and consistently recognized. The GLN provides a standardized format to identify various types of locations, including warehouses, distribution centers, and retail outlets, which is essential for logistics, inventory management, and efficient supply chain operations. Being distinct from product identification numbers like GTINs (Global Trade Item Numbers), the GLN's role in pinpointing locations helps streamline operations within trading networks, making it easier to track and manage inventory across different facilities.

Other options discuss functions that do not align with the primary purpose of the GLN. For example, counting products sold, returning damaged goods, or calculating inventory turnover are activities related to inventory management and logistics but do not define the identification capabilities of the GLN itself.
