BNবাংলা#Product identifiers
Product identifiers are the codes that tell shopping platforms exactly which product you are selling. The most important are the GTIN, which is the number behind a barcode, the manufacturer part number and the brand name. Articles tagged here explain what each identifier means and when a platform requires it. They cover where to find identifiers, how to store them in a store system and how to format them in a feed. You will also learn what to do for handmade, custom or private-label goods that have no barcode. Correct identifiers help products match searches and avoid disapprovals.
