GLN

The Global Location Number (GLN) is a globally standardized identifier developed by GS1, the same organization that manages barcodes and GTINs. GLNs are used to uniquely identify parties and places involved in supply chain transactions - such as buyers, suppliers, and warehouse locations.

How GLNs are used at Amazon:

• Warehouse GLN – identifies a specific Amazon Fulfilment Centre
• Company GLN – represents a vendor or seller’s business entity
• Buyer GLN – identifies Amazon as the purchasing party
• Supplier GLN – identifies the selling vendor or manufacturer

GLNs are especially important for:

• EDI transactions (POs, invoices, ASNs)
• Global supply chain traceability
• Automated logistics and compliance
• Matching entities across multiple systems or countries

💡 Example: When a vendor ships goods to an Amazon FC via EDI, both the supplier’s GLN and the warehouse’s GLN are included in the ASN to ensure precise delivery tracking.

In short:
GLN is a standardized 13-digit number that uniquely identifies companies and locations in Amazon’s global supply chain - essential for accurate and automated operations.
