What is a Global Location Number (GLN)?

 


Global Location Number (GLN) Explained

A Global Location Number (GLN) is a crucial element in supply chain management, serving as a unique 13-digit identifier for any location, legal entity, or function within a business. It's a globally recognized standard managed by GS1, the organization responsible for barcode standards.


Purpose and Functionality

The primary purpose of a GLN is to pinpoint specific locations, enabling improved visibility and efficiency throughout the supply chain. This includes identifying manufacturing facilities, distribution canters, retail stores, and even specific departments within a company. GLNs facilitate accurate shipping, support electronic data interchange (EDI), and streamline business communications. For example, when a supplier sends materials to a warehouse, they use the recipient's GLN to ensure the shipment reaches the correct facility.


Benefits of Using GLNs

Using GLNs offers several key advantages:


Improved Supply Chain Efficiency: GLNs ensure that shipments, invoices, and deliveries go to the correct location, reducing errors and minimizing costly delays.


Standardized Business Communications: GLNs enable businesses to communicate with trading partners, suppliers, and customers using a globally recognized system, which is especially valuable in industries like retail, healthcare, and logistics.


Compliance: Many large retailers, healthcare organizations, and government entities require suppliers to have a GLN for EDI and other transactions, ensuring compliance with industry standards.


Facilitates Traceability: In industries like food and pharmaceuticals, GLNs help track products and materials back to their source, aiding in managing recalls and audits.


GLNs in Exports


GLNs play a vital role in facilitating exports by:


Standardizing Identification: GLNs provide a universal method for identifying locations, eliminating the need for trading partners to assign proprietary numbers, which simplifies international trade.


Streamlining EDI: GLNs are essential for electronic data interchange, which is crucial for international trade. They enable accurate and efficient communication between businesses, facilitating the exchange of orders, invoices, and other documents.


Improving Traceability: GLNs enhance the ability to track goods throughout the supply chain, which is critical for regulatory compliance and ensuring product safety in international markets.


Facilitating Compliance: Many countries and industries require the use of GLNs for import and export documentation, ensuring compliance with international trade regulations.


Reducing Errors: By providing a unique identifier for each location, GLNs minimize errors in shipping, invoicing, and other processes, leading to more efficient and cost-effective export operations.


Obtaining a GLN

To obtain a GLN, businesses must register with GS1, the global barcode standards organization. If a company already has a GS1 US GTIN or a GS1 Company Prefix, they have already been assigned a GLN and can find it by logging into the GS1 US website. If more GLNs are needed, they can be purchased through GS1.


GLN vs. GTIN

It's important to distinguish between GLNs and Global Trade Item Numbers (GTINs). While both are unique identifiers managed by GS1, they serve different purposes. GTINs identify specific products, while GLNs identify locations. Both are critical for efficient supply chain management, with GTINs identifying what products are being sold or shipped and GLNs identifying where business activities occur.
