A GLN, or Global Location Number, is used to identify your business as a legal entity, often via the use of EDI (Electronic Data Interchange). It can also be used to identify different offices, warehouses or even specific shelves within a warehouse. If you’re selling to major retailers they’ll often ask for your GLN. You can create your own GLNs once you’re a member of GS1 UK – from the unique company prefix we licence to you.
