Have you ever been in a group of physicians or software developers and heard strange terms thrown around. You listen harder in an attempt to make heads or tails of the conversation. For a while, you might think you are in a foreign place. That is because every industry develops a language that is unique to it. The same is true for Amazon sellers. We have gathered a list of forty commonly used terms that Amazon sellers use. If you are starting out, these can help you understand what they’re all saying.

ASIN (Amazon Standard Identification Number)

This is one of the terms used by Amazon sellers exclusively. Amazon assigns the ASINs. It is a unique number consisting of 10 letters and/or numbers that identify items. The ISBN for books is the same as ASIN. By now, the Amazon catalog has probably assigned ASIN to almost any product available.  If you do not find an ASIN for your item, then Amazon will create one for that item.


This means the merchant does not have the inventory of an item but it is on order and they expect it to be in stock soon. Amazon allows most products to be listed as back-ordered. The merchants can accept orders for that item and ship once it is back in stock.

BMVD (Books, Music, Video, and DVD)

Every Amazon seller uses this term frequently, either in frenzy or jubilation. The coveted prize of Amazon sellers. The box on the right of a listing that has the ‘Add to Cart’ and ‘Buy Now’ buttons. Featured sellers compete for this position. It is the button most buyers click to make their purchase. A listing may have many sellers. Amazon, through an undisclosed algorithm, chooses which seller will be in the Buy Box. Inspite of the secrecy behind the algorithm, we know some of the factors that can help win the Buy Box.
