fnskus, on the other hand, are specific to every product and vendor. This is crucial because it makes it easier to identify which item belongs to which seller when several sellers use an Amazon Fulfillment Center to offer the same product.

Products of the same ASIN that do not have a Fnsku are mixed together at the FC. These might potentially be dispersed and divided among FCs nationwide. This might or might not be a problem. For instance, you might win the Buy Box and sell a product to a buyer, but your competitor’s item might be chosen and packaged instead of yours, in which case Amazon would give the competitor credit. vendor as opposed to you. This might work out if you are the manufacturer and the lone seller on the product detail page.

However, it can cause issues for bigger companies or ASINs where several sellers are in competition with one another. These days, as Amazon battles counterfeiting much more vigorously, Fnsku can play a crucial role in determining which seller or item is at fault. A Fnsku can assist in identifying which product is fraudulent and which seller sold it if one seller is putting in counterfeit goods that eventually find their way to buyers. On the other hand, if mixed inventory is present without Fnsku , Amazon might not be able to identify the right vendor for an issue. Then, Fnsku make sure that authentic products are sold by authorized sellers without encountering account problems. This could span from negative product or account reviews to account bans. If you’re an FBA seller with concerns about counterfeiting, you might want to consider Amazon’s product serialization service, the Amazon Transparency program, which goes even farther in this regard.

Additionally, Fnsku come in handy if a product becomes lost because they make it easier to locate the item and credit any lost inventory to the appropriate seller account.
