Amazon Vocabulary

This is a handy little guide to help you understand some of the terminology that is used inside the Amaosphere (see what we did there?) so you don't get lost or frustrated. These are not in any particular order and just for reference. If the meaning of these terms change then we'll change the text in this helpful guide.

Box Content

This phrase is best explained over at our box content page as it's a more in depth explanation of the process but essentially it is Amazon's requirement that you tell them what is inside each of the boxes you send to them IF there are multiple boxes coming inbound to them to the same warehouse.


The ASIN is the Amazon Stock Identifier Number for every product on their catalog. In the hierarchy of codes that identify products, this is the at the core and the bottom and is the most essential for comparing apples-to-apples when comparing products.

Amazon Marketplace Web Service (Amazon MWS) is an integrated web service API that helps Amazon sellers to programmatically exchange data on listings, orders, payments, reports, and more. Data integration with Amazon enables high levels of selling automation, which can help sellers grow their business. By using Amazon MWS, sellers can increase selling efficiency, reduce labor requirements, and improve response time to customers.

Merchant Stock Keeping Unit.
A unique number you or AL assign to each different item you sell. Also called SKU.

The FNSKU is an acronym for Fulfillment Network SKU or Fulfillment Network Stock Keeping Unit. The FNSKU is the way that Amazon identifies a product as unique to the seller that has sent it to the Amazon fulfillment center.

Seller Label - No Label

Seller label is when you label your own products. 

No label is when Amazon wants to label your products and Co-mingle them even after you chose the option to label products yourselves.

First step that we'd recommend is Turning off co-mingling in your Seller Central settings.

Occasionally Amazon will split your shipment with multiple products going to the same warehouse but on different shipping plans. This is not ideal as it increases your spend on postage and generally seems off or unfair from the sellers perspective. It can look like the picture below when this happens.

Seller is blocked by the AndonCordManager

This error is caused by a restriction on your Amazon seller account. Recently a seller ran into this error and it turned out that a shipment was overweight and they needed to go in and acknowledge that so Amazon would let them list again.

Do Contact Seller Central Support to confirm whether your recent shipment was over the weight limit.
