Amazon fulfillment center

The warehouse where your inventory is stored. Amazon has many fulfillment centers throughout the country. When you create a shipment, we'll tell you which items need to be in a separate shipment, and we'll tell you for each shipment which fulfillment center to send the items.

Amazon Fulfillment Network

The Amazon Fulfillment Network refers to the infrastructure that Amazon FWS taps into to offer an optimized and cost-effective fulfillment solution for merchants.

See Also Fulfillment by Amazon.

Amazon Standard Item Number

The Amazon Standard Item Number (ASIN) is a ten-digit Amazon.com product identifier. Each ASIN is unique. When you submit a SKU, it is linked to an ASIN.

commingled

Your inventory is commingled (also called stickerless) if you send it to the fulfillment center to be combined with inventory that Amazon or other merchants have of the same kind and condition. When someone purchases an item from your inventory, Amazon doesn’t physically distinguish your inventory from that of other merchants. However, Amazon will decrement inventory availability for the sale from you, so you always have up-to-date knowledge of your stock. For further information about commingled inventory, go to the Help for Stickerless, Commingled Inventory.

An item is non-sortable if it is oversized. For more help, go to the FBA Guidelines and Frequently Asked Questions page.

See Also sortable , oversized .

oversized

The dimensions and weight of the product being fulfilled determine whether the product is oversized or not. Products that are larger than 18"x14"x8" or that weigh 20 pounds or more are considered oversized.

Secret Access Key

A key assigned to you by Amazon Web Services (AWS) when you sign up for an AWS account. Used for request authentication.

To learn more about request signatures, including when to use them see Your AWS Account.

SKU

A stock keeping unit is a specific merchant's product identifier. The SKU is a critical piece of data in every inventory file that you submit to us. Amazon.com uses the SKUs in your inventory file to associate your products with the appropriate product detail page in our catalog (if one already exists). This means the following:

  • Every product in your inventory file must have a unique SKU.

  • An existing SKU cannot be changed; it remains in the catalog until you delete it. That is, you cannot change SKU "123" so that it reads "ABC" in our system simply by changing the SKU in your inventory file.

sortable

Amazon has three classifications for fulfillment items: media, non-media, and oversized. Media items include books, music, software, video games and videos (DVD, VHS). Non-media items include everything else.

An item is sortable if it is media or non-media. Anything classified as oversized is non-sortable.

See Also non-sortable , oversized .

Your inventory is stickerless (also called commingled) if you send it to the fulfillment center to be combined with inventory that Amazon or other merchants have of the same kind and condition. When someone purchases an item from your inventory, Amazon doesn’t physically distinguish your inventory from that of other merchants.

web services description language

The service's Web Services Description Language file describes the operations along with the format and data types of the actions' requests and responses. Your SOAP or other toolkit interprets the WSDL file to provide your application access to the actions. For most toolkits, your application calls a service action using routines and classes provided or generated by the toolkit.
