ASIN

If you want to become a seller through Amazon.com, it is important that you know how Amazon Standard Identification Numbers (ASINs) work. Not only do they make finding your product easy, they also work in preventing counterfeiting.

What Is an ASIN?

An ASIN is a unique 10-character alphanumeric code that is used for identifying products within the Amazon organization. Every product that sells through Amazon.com or its websites meant for other countries comes with its own ASIN. With books, their ISINs are the same as their 10-digit International Standard Book Numbers (ISBNs).

If you wish to sell a product that does not sell on Amazon yet, you will need to get a new ASIN. To create a new ASIN, you will need to know your product’s Global Trade Item Number (GTIN). Commonly used GTINs include ISBNs, EANs, and UPCs. Amazon then uses these codes to create a unite ASIN. In many cases, you may use an ASIN to obtain a product’s corresponding EAN code.

If a product you wish to sell already sells on Amazon, you need to use the same ASIN code. Finding the ASIN for an existing product on Amazon is easy. You get to find it in the web address of the webpage in question. It is also listed under product details, where you get to view further information such as size, weight, or number of units.

Amazon limits the number of ASINs a new seller may create every week in order to protect its customers’ online shopping experience. This policy stays in effect until you establish a reasonable sales history with the company. Typically, your capacity to create ASINs increases once there is an increase in sales.

Since you do not get to create an unlimited number of ASINs upfront, you might want to consider prioritizing which products you wish to sell first. Ideally, you should go ones you expect to sell quickly, as this will have a positive effect on your ability to create new ASINs.

Amazon might temporarily disallow established sellers from creating new listings if they end up creating too many ASINs. It reviews the status of such sellers weekly.

Amazon customers may use ASINs to look for specific items on the website. All they need to do is enter the ASIN of a product in the search box and click on go. The desired product then appears as the only result.


Organization in Charge of ASIN

Amazon.com and its partners are responsible for assigning ASINs.


History of ASIN

Amazon has relied on the use of ASINs almost since the time the company began online sales. Before Amazon’s global expansion, ASINs were unique internationally. However, the uniqueness of ASINs is now limited within specific marketplaces.
