Pokémon maintains a uniform barcode and SKU code system. Genuine products have SKU codes with three numbers followed by a dash and five numbers, and barcodes beginning with “0-820650,” reflecting the SKU. Counterfeit products frequently have generic codes and duplicated barcodes, as seen in the examples below:
Example:
Pokémon Sword & Shield 9: Brilliant Stars – Booster
SKU: 180-80996 / UPC: 0820650809965
Counterfeit products may deviate from this pattern, helping savvy consumers identify potential fakes.
