The Eureka SKU is a universal product code (UPC) that univocally defines a specific product in the bicycles' market.
Sharing the Eureka SKU of a listing bicycle, for example, means to indicate a very well-defined combination of Brand, Model, Mounting, and Model Year parameters that define a single bike model and no one else. The Eureka SKU of an Ad product, instead, is built from other information that guarantees it is still unique compared to all present, past, and future products managed by EurekaBike.
The Manufacturer Code is a unique code that defines a particular Model from the side of the producer or brand. Often, this code can be found in manufacturers' catalogs or websites, but due to producers not adopting always the same standards, when the Manufacturer Code is not available, at EurekaBike we give the product an internally created Manufacturer Code based on the defining parameters of the product itself.
