Your Global Location Number (GLN), is typically the primary physical location of your business or business function you have assigned to this process.
To access your GLN, or if you have forgotten what this is. You need to check with your UK representative/account manager @GS1 UK or log in to your MyGS1 UK account online (GS1 UK members only), and from your number bank you have access to GLNs.
If you are still struggling call freephone 0808 178 8794 or from overseas +44 207 092 3504. If you are a member of another GS1 membership organisation please check what GLNs you have access to.
