Match your products

The Amazon catalog features products sold by many sellers. To prevent the same product from appearing multiple times and diminishing the customer experience, Amazon uses product matching to find and eliminate duplicate listings.

Product matching helps you match your product to an existing listing. It then adds your offer information to that listing. If a product does not yet exist in the catalog, you can create a new product detail page.

Good product matching directly benefits you. When you match your product to an existing listing, you ensure that customers can find your offer.

You can make the most of product matching by appropriately classifying your products in the inventory files you upload to the website. When you upload your inventory listings, Amazon runs the data through our matching engine to link your products with the appropriate catalog entry.

Product matching display

A key feature on Amazon is that the same product can be sold by multiple sellers. One seller "wins the Buy Box," while all other sellers appear when the customer clicks "More Buying Choices." The Buy Box winner is determined by a combination of product availability, retail price, and other factors. See The Buy Box for more information.

When customers find a product, they see the product detail page, which includes the Buy Box ("Ready to Buy") and a "More Buying Choices" box (if several sellers offer the same product).

When multiple sellers are selling the same product, the customer can view a list of offers.

Troubleshoot product matching errors

Here are some possible errors that might occur when matching a product or creating a new product entry:

  • Multiple products using the same standard ID.

    In this case, we cannot determine which entry should be matched to your product. Contact us about this error.

  • Multiple products using the same product data.

    The product data, such as the manufacturer and manufacturer part number, is not discriminating enough. For example, you submitted a manufacturer and manufacturer part number that appears to match more than one product. Enter more specific information to find a match.

  • Same product using multiple SKUs.

    A product match was found, but you already have a different SKU associated with it. This can happen if you re-used a SKU previously associated with a different product. To fix this problem, delete the SKU and resubmit the product data.

  • Adding a new product fails.

    If you submit a product, but you do not include the required fields for that product type, you will get an error message and the listing will not be added to the catalog. This ensures that wrongly classified or cataloged products do not appear on the live website. To resolve this problem, re-submit the product with all the required data.

Tips for successful product matching

  • Use unique standard product identifiers.

    Use a standard product identifier when submitting your products. The three top standards are ISBN, UPC, and EAN. This is the most important and reliable piece of data in the matching process.

  • Always use a standard ID when creating a new product.

    The only time it's incorrect to use a standard ID is in a parent product. If you are creating variations, you should use the standard ID only for the child products. Do not use the ASIN.

  • Use the manufacturer part numbers issued by the manufacturer.

    The manufacturer part number is different from the SKU. The manufacturer part number is the standard by which manufacturers identify their products.

  • Provide manufacturer name, brand, or publisher.

    This data is almost always required to create a new product.

  • Limit the product name to its official title.

    Do not include merchandising information in the item name. Use the product description and the bulleted list for adding merchandising details. For example, do not include "Reduced Price" in the name of the article.

  • Use the specific attribute fields correctly.

    For example, product dimensions such as height, width, and weight should be specified in the Height, Width, and Weight attributes. Do not use general purpose merchandising fields for these values.

  • Do not re-use SKUs.

    If you must change your SKU for a product, do not re-use or recycle old SKUs. Issue a new SKU for the item, and then re-assign the product to the new SKU.

  • Do not submit a UPC, EAN, or manufacturer part number for parent items.

    If you create parent and child products for variations, the product data for the parent product should contain only data that is common to all child products. This includes Item Name, Product Description, Featured Bullets, and so on. Standard identifiers such as UPC, EAN and manufacturer part number are unique for each child product. Do not copy these values into the attributes for the parent product.

Errors and Troubleshooting

Here are some possible errors that might occur when matching a product or creating a new product entry:

Product Matching Errors

If you attempt to match a product and the match fails, the failure might be due to two possible errors:

  • Inconclusive results: The Amazon.it catalogue contains multiple candidate matches for your submitted product, and you did not submit enough data to determine the correct one. There are two possible cases:
    • We found two or more products with the same standard identifiers, such as UPC or EAN, and we cannot determine which entry should be matched to your product. Amazon.it must resolve the data for these UPCs for this UPC to surface on a product detail page. Please use the Contact Us form (at the bottom of this page) to contact us about the error.
    • The product data (such as the manufacturer and manufacturer part number) you submitted is not discriminating enough. For example, you submitted a manufacturer and manufacturer part number that appears to match more than one product. Enter more specific information to find a match.
  • Same item with multiple SKUs: we matched to a product, but you already have a different SKU associated with it. This can happen if you re-used a SKU previously associated with a different product (that is, perhaps the product is discontinued or deleted). To correct this, delete the SKU and then resubmit.

Product Creation Errors

If you attempt to create a new product entry and the process fails, the most likely cause for the failure is that you did not submit enough data to create the new product. Typically, a key attribute, such as EAN, manufacturer, brand, and so on, is missing. If you submit a product entry in a data feed but you do not include the required fields for that product, the Amazon.it platform generates an error message and prevents the product from inclusion in the Amazon catalogue. Blocking the inclusion of products without required data ensures that wrongly classified or catalogued products do not appear on the live Web site. To resolve this problem, re-submit the product with a complete product entry.
