A barcode is a scannable number that identifies a product uniquely. The common standard in retail is GTIN/EAN, obtained in Turkey through GS1. Every variant of the same product carries its own barcode. Product matching on marketplaces, picking in the warehouse and stock counts all run on this number; a product without a barcode is a product that cannot be measured.

When different sellers enter different barcodes for the same product on a marketplace, listings fail to merge and the product does not show up in price comparison. For own-manufactured or imported products with no barcode, numbers have to be obtained through GS1 membership; using numbers found at random online creates problems that go as far as listings being taken down.
