ASIN (Amazon Standard Identification Number):

 This is the most common type of product ID on Amazon. It's a 10-character alphanumeric code assigned to each product. ASINs are unique to Amazon and are used to identify and differentiate products within the marketplace.

ISBN (International Standard Book Number):

ISBNs are unique numeric codes used to identify books. When listing books on Amazon, sellers can use the ISBN as the product ID.

UPC (Universal Product Code):

 UPCs are widely recognized barcodes used for retail products. Amazon accepts UPCs as product IDs for certain categories of products, particularly in the Electronics category.

EAN (European Article Number): 

EANs are similar to UPCs and are used as product IDs in Europe. Amazon also accepts EANs for specific product categories.

Amazon Variations: 

Amazon allows sellers to create product listings with variations, such as different sizes or colors, under a single parent ASIN. Each variation within the parent ASIN will have its own unique ASIN. This helps customers compare different options of the same product on a single product detail page.

Amazon Marketplace IDs: 

Amazon operates various international marketplaces, such as Amazon.com, Amazon.co.uk, Amazon.de, etc. Each marketplace has its own unique identifier, known as the Marketplace ID. This ID is used by sellers to specify the marketplace where they want to list their products.

Amazon Serial Number: 

Some products, particularly in the Electronics category, may have a serial number associated with them. This serial number can serve as a unique identifier for tracking and warranty purposes. While not a primary product ID, sellers may need to provide the serial number when listing certain products on Amazon.

FNSKU (Fulfillment Network Stock Keeping Unit): 

FNSKU is a unique identifier assigned to products that are fulfilled by Amazon (FBA - Fulfillment by Amazon). When sellers send their inventory to Amazon's fulfillment centers, each unit is labeled with an FNSKU barcode. FNSKUs are used to track and manage inventory within Amazon's fulfillment network.

External Product IDs:

 In addition to the product IDs mentioned earlier, Amazon also allows sellers to provide their own external product identifiers, such as Manufacturer Part Numbers (MPNs) or Custom SKU numbers. These external IDs can be used to match products to existing catalog entries or help sellers track their inventory internally.

When listing a product on Amazon, sellers usually need to provide one of these product IDs to create a new product listing or match an existing product in the Amazon catalog. Each product ID helps Amazon maintain a unique identity for products, enabling accurate search, categorization, and tracking within the marketplace.

It's important to note that the specific product IDs required or accepted by Amazon can vary depending on the category, fulfillment method (FBA or FBM), and other factors. Sellers should refer to Amazon's guidelines and Seller Central for the most up-to-date information and requirements related to product IDs.
