Do I Need a New GTIN?

Updated 1 year ago ​by Merch Transformation Change Management

If an incorrect GTIN is assigned to any level of an item (Sellable, Orderable, Each, Inner Pack, etc.), you will need to set up the item again to correct the issue and generate a new Walmart Item Number.

What principles determine when I need a new GTIN?

Global industry standards state that the change of a pack quantity will require a new GTIN for that quantity hierarchy level. This standard was put into place while GS1 reviewed the management of GTINs using three guiding principles (below). At least one of the guiding principles must apply for a GTIN change to be required. 

  1. Is a consumer and/or trading partner expected to distinguish the changed or new product from previous/current products?
  2. Is there a regulatory/liability disclosure requirement to the consumer and/or trading partner?
  3. Is there a substantial impact to the supply chain (e.g., how the product is shipped, stored, received)?
