*While you can change either the Product Description or Brand Name for a product set to In Use, this is commonly done to correct a typographical error.  You cannot change the Product Description to reflect a new product, per the GTIN Management Standard: “Any new product requires the assignment of a GTIN.” Similarly, based on the impact of the Brand Name change on your trading partners, you may want to consider assigning a new GTIN, per the GTIN Management Standard: “A change to the primary brand that appears
on the trade item, requires assignment of a new GTIN.”
