Key takeawaysNAD+BY (Buyer) → buyer GLNNAD+SU (Supplier) → supplier GLNNAD+DP (Delivery Place) → delivery location GLN (usually the retailer store/DC, NOT the legal seat)NAD+IV (Invoicee) → invoicing entity GLN Definition GLN (Global Location Number) is a 13-digit GS1 identifier marking a unique physical or legal entity in a commercial transaction: legal seat, warehouse, store, retailer delivery dock, specific receiving bay. How it appears in EDI NAD+BY (Buyer) → buyer GLN NAD+SU (Supplier) → supplier GLN NAD+DP (Delivery Place) → delivery location GLN (usually the retailer store/DC, NOT the legal seat) NAD+IV (Invoicee) → invoicing entity GLN Common confusion: physically shipping to the legal-seat GLN instead of the store GLN → rejected order and penalty. Practical example: Carrefour Carrefour has one GLN for the legal entity (invoicing) and separate GLNs for each hypermarket / distribution center. The supplier must keep a complete map: internal location code ↔ Carrefour GLN. How to obtain one Companies with a GS1 prefix issue their own GLNs For retailer/partner GLNs, they are shared at onboarding or pulled from GDSN Azuvio keeps a pre-mapped library for native retailers (Carrefour, Auchan, Kaufland, Lidl, Mega Image, Profi, Metro, Dedeman, Hornbach, Leroy Merlin) Frequently askedCan a GLN be reused if a location closes?No. GS1 rules require a deactivated GLN not to be reused for at least 48 months from deactivation.Difference between GLN and GTIN?GTIN identifies a product (what); GLN identifies a location or legal entity (where/who).
