Product identifiers

Sellers are encouraged to supply product identifiers as item specifics whenever these identifiers are available for their products. Refer to Structured Data - Product Identifiers for additional information.

Valid types of product identifiers in the Item.ItemSpecifics.NameValueList.Name field are:

• A Global Trade Item Number (GTIN). GTINs are a set of globally recognized identifiers, including:
  • EAN (European Article Number)
  • ISBN (International Standard Book Number)
  • JAN (Japanese Article Number — used only in Japan)
  • UPC (Universal Product Code)
• BrandMPN which comprises the following fields:
  • Item.ProductListingDetails.BrandMPN.Brand
  • Item.ProductListingDetails.BrandMPN.MPN

For any Item.ItemSpecifics.NameValueList.Name, the Item.ItemSpecifics.NameValueList.Value field must comply with the following guidelines to avoid an error condition:

• The EAN must comply with the GTIN-13 standard.
• The ISBN must comply with the ISBN-10 or ISBN-13 standard.
• The JAN must comply with the GTIN-13 standard.
• The UPC must comply with the GTIN-12 or UPC-A standard.
• When identifying a product with BrandMPN:

  • Item.ProductListingDetails.BrandMPN.Brand must be the actual name of the product's brand and cannot be any of the following:

    • Strings with only special characters (e.g., "&*#@")

    • Strings such as:

      • "Brand new,"
      • "Made in China"
      • "See the description below"
      • "100% compatible with listed model"

      One exception is when the product is not branded — its Item.ItemSpecifics.NameValueList.Value can be Unbranded.

  • Item.ProductListingDetails.BrandMPN.MPN cannot contain only special characters (e.g. "$amp;%^&").

Multiple-variation listings

For listings that have multiple variations:

• Specify GTIN values in Item.Variations.Variation.VariationSpecifics
• When identifying a variation with BrandMPN:
  • Set Item.ItemSpecifics.NameValueList.Name to Brand
  • Specify the actual brand name/value (e.g., Apple, Nike,) using Item.ItemSpecifics.NameValueList.Value
  • Specify MPN values in the Item.Variations.Variation.VariationSpecifics.NameValueList container where:
    • Item.Variations.Variation.VariationSpecifics.NameValueList.Name is set to MPN.

    • Item.Variations.Variation.VariationSpecifics.NameValueList.Value is the specific MPN for the specific item.

      For example, DSC-RX100/B, ILCZVE10L/B, fcb-ex980sp, etc.
