University - General Information About Amazon
Listing ID

Each time a product is listed with Amazon, it is given a value, derived by Amazon. This value is called the Listing ID, and should not be confused with other identifiers, such as the ASIN (Amazon Standard Identification Number). If a product is relisted, it receives a new Listing ID.
The Listing ID is available as a filter in the Manage Orders tool to help sellers find all orders associated with the particular Listing ID.
