Is GS1 the only organisation that can supply barcode numbers?
If you want unique, accurate, standards-based barcode numbers, then GS1 is the only organisation in the world that can supply you with legitimate numbers. Locally, GS1 Australia is the only authorised source for GS1 barcode numbers
Barcode number re-sellers do exist. These businesses have bought barcode numbers off other companies and try to on-sell them. Unfortunately, they threaten the integrity of the global GS1 system and create confusion in the global supply chain.
We strongly advise that you get your barcode numbers from GS1 Australia. This will ensure that your numbers will be recognisable by all other parties in your supply chain.
