UPC Guidelines for multi-packs
As a general rule, each unique product manufactured and sold to consumers must have a unique trade item number (UPC, EAN, ISBN, or GTIN). An item sold singly is a different " sellable unit " from a pack (or set) including multiples of that same item. Each sellable unit defines a separate product that must have its own product identifier, usually a UPC.
This section contains guidelines for listing multi-pack products. In most Amazon categories, sellers are required to use a separate UPC for multi-pack products, and they must also indicate the " item package quantity " when listing multi-packs. Exceptions to the UPC requirement are provided in the sections below.
Product bundles are composed of different products (not multiples of the same product) and each bundle requires its own unique UPC (or EAN). For a detailed discussion of bundles, see the Product Bundling Policy .
For more information about packs, bundles, and case packs, see How Products are Defined .
