Table of Contents

Today, Amazon has surpassed Google when it comes to search results. When you look for a product on Google, you will find the first few results will be by Amazon. It has become the world’s leading e-commerce store. Initially, Amazon only sold books. As the e-commerce store gained popularity, it began adding multiple products to the site.

But managing so many products wasn’t easy. That is when Amazon came up with a system. They introduced identification numbers. ASIN is just one of the many numbers. UPC, ISBN, GTN-14, and EAN are other numbers used to categorize products on Amazon.

What is an ASIN number?

Amazon has 353 million products in its catalog. With the help of an identification number, Amazon can keep track of all the products. The ASIN is alphanumeric. If you plan to run a business through Amazon, you need to have an Amazon ASIN.

You cannot sell items without specific identification codes. Anyone who wants to sell on Amazon needs to have an ASIN number. All products except for books require an ASIN number. If you are selling books, then you will need an ISBN. ASIN is a 10-digit number.

Amazon’s Identification number is not internationally standardized. National Amazon sites require specific ASINs.

What ASIN Stands For?

ASIN stands for Amazon Standard Identification Number. If you want to sell a product on Amazon, you need to have an ASIN number. Every product that is sold on the e-commerce website has an ASIN. It helps customers find the right product.

For example, you are looking for a particular watch. There might be multiple product pages for the watch. That means many people are selling the same watch.

Importance of ASIN’s to Amazon and sellers          

Amazon ASIN is essential for both sellers and customers. It is also the most effective way to monitor inventory. With the help of the unique identification number, customers can find their product with ease. Amazon has millions of products in its catalog. Buyers often find it challenging to find the exact product.

They might spend hours looking for the product. But because there are so many products, the particular item does not turn up in search results. Endlessly searching for a product can become frustrating. By putting the ASIN number in the search bar, customers can easily find the desired product.

Sellers also benefit from the Amazon Standard Identification Number. They can see how many other competitors are selling the same product. Amazon does not allow sellers to create a new ASIN number. Most of the items sold by people already exist on Amazon’s product catalog.

If Amazon allows you to create a new ASIN code, that means your product is unique. When you have your very own ASIN, there is very little competition. Being able to create your identification number is rare. But every once in a while, a product is not listed on Amazon. In that case, you will be allowed to create a new Amazon ASIN number.

ASIN is vital for Amazon’s smooth functioning. Managing millions of products can be overwhelming. That is why an identification number is so crucial. It helps Amazon index catalog pages. ASIN is also essential to track inventory, oversee orders, and avoid counterfeit sales.

How can I find my ASIN ?

Where to Find the ASIN Number on Amazon

When individuals want to sell a product on Amazon, they need to look up their ASIN number. One item can have multiple sellers. But the ASIN number for that product will be the same. Even though numerous people are selling an item, the Amazon ASIN number for that item will be consistent.

What Is The ASIN Creation Policy?

If you create an ASIN for an existing product, Amazon will suspend your account. The suspension can be temporary or permanent. Sometimes sellers accidentally make a new ASIN for an existing item. In that case, Amazon ends up merging the product pages.

Merging of product pages can be bad for a seller. It becomes harder for a consumer to find a particular product. It is better to search for the existing ASIN and use it to list your item. A seller can manage everything from Amazon Seller Central.

You can find your ASIN using three different ways.

#1 Use the URL of the Amazon Product Listing

When you type in the URL in the search bar, you will find the ASIN. You can copy the number from the URL.
