Transparency Program is a service that identifies products. The main purpose of this program is to prevent counterfeit items from being sold. Thanks to this, customers can safely buy original products, and manufacturers can be sure that their products will not be sold by another company. This increases the confidence of both customers and sellers. Amazon aims to provide better customer service so that it receives the ordered product, not its imitation. The customer can easily notify Amazon of counterfeiting. Each brand that is registered in the Transparency Program receives a bar code. The brand owner is also responsible for placing the code on all products, regardless of whether the products are sold on Amazon or another platform. The codes are unique, assigned to only one product, which helps to identify the brand. Customers can scan codes to verify product authenticity using the Amazon app.
