When adding a new product to your catalog you can validate the UPC or EAN by enabling the client setting (Settings > Client Settings) Enable UPC Validation
. When saving the UPC to the product this process will:
- Verify that another product in the same company does not have an identical UPC. (It will not check another company under the same client.)
- Verify that the UPC is between 12-15 characters.
- Validate the accuracy of the UPC. The validity of the UPC is established if the last digit of the UPC, known as the "check digit", confirms the accuracy of the UPC by means of a special algorithm.
To allow UPC duplication on a parent product of Independent kits, enable the sub-setting Enable UPC Validation - Individual Kit Override
. This is necessary because kits with an Independent dependency are recognized as a separate product from the individual components, while they physically consists of same products with the same UPCs.
