Item Identifiers

All items for sale on Amazon.com have identifiers. There are two major kinds. The first identifies items regardless of whether or not they can be purchased:

  • ASIN — Amazon Standard Item Number

    An alphanumeric token that uniquely identifies items in the Amazon marketplace.

    All items in the marketplace have an ASIN. This is by far the most common identifier. ASINs are used by the majority of Product Advertising API operations.

The second identifies items that can actually be purchased:

  • OfferListingId — An alphanumeric token that uniquely identifies items in the Amazon marketplace that can be purchased

    All items in the marketplace that can be purchased have an OfferListingId. This is by far the most common identifier for items that can be purchased.
