What Is Amazon ASIN – A Full Guide To Create ASINs

Amazon’s massive product catalog is ever-growing as sellers create thousands of new ASINs each day. Keeping the catalog organized and providing accurate search results is a fundamental aspect of a successful customer experience. For this reason, Amazon ASIN is so important for both buyers and sellers.

After reading this article, you understand what exactly is Amazon ASIN and how to get one.

What Is Amazon ASIN?

Amazon ASIN stands for Amazon Standard Identification Number. It is a unique combination of 10 characters: numbers, alphabets, or their combination. Moreover, it functions as an identifier that Amazon.com and its partners assign to a product. Unique ASINs allow sellers and customers to find the exact product they are looking for within the massive product catalog. Therefore, there can never be two items with the same ASIN.

However, there are some exceptions to this uniqueness. For instance, a specific ASIN is unique only within the same marketplace. This means that Amazon sites in the US and Germany may use different ASINs for the same product. Moreover, if you are selling books on Amazon, the ASIN is the same as the ISBN (International Standard Book Number). 

Why Is Amazon ASIN Important?

Amazon ASINs serve an important function of delivering accurate product searches, which again enhance the customer experience. There are several reasons why ASINs are relevant to both buyers and sellers alike. 

First of all, Amazon’s whole product catalog structure is based on ASIN numbers. Due to unique coding, sellers can accurately track their inventory. However, the vital part is related to potential customers finding the items they want to purchase.

With these unique identifiers Amazon can organize and index catalog pages. As a result, shoppers receive requested search results and can browse products through multiple categories. Additionally, customers can type the product description or ASIN into the search box and find the exact product they are looking for. All of these combined allow Amazon to offer its customers an optimized shopping experience.

How to Find Amazon ASIN Number?

There are several ways you can find an Amazon ASIN number for your product.

  • Search the product on Amazon and look at the browser’s address bar. You can find the Amazon ASIN in the URL after the product’s name and “dp.” In this example, it is B07FZ8.
  • An alternative option is to search for the product on Amazon and navigate to product details further down on the page.
  • As a last option, you can use a third-party software tool built for ASIN lookups. These tools identify your products from a bulk upload and match them with a corresponding ASIN. It is especially handy if you have thousands of products and finding them individually would be too time-consuming.

What Is The ASIN Creation Policy

ASIN helps Amazon to index the catalog and display the exact product in the search results. Therefore, it’s crucial to identify and use the correct ASIN for your products as an Amazon seller. To ensure the best shopping experience for its customers, Amazon has an ASIN creation policy that keeps the catalog organized and prevents fraudulent listings. 

Duplicate ASINs

According to Amazon, if you want to sell a product in the catalog, you have to match it to the existing ASIN by creating an offer. Creating a new ASIN when the product already exists is prohibited. As a consequence, the sellers’ privileges may be temporarily suspended or permanently removed. However, if your product is not in the Amazon catalog, you need to create a new ASIN for the product. We’ll cover this topic shortly.

Creating a new ASIN when the product already exists in Amazon’s catalog is prohibited and can result in your ASIN creation or selling privileges being temporarily suspended or permanently removed. In order to avoid creating duplicate ASINs, ensure that you always use the appropriate UPC, EAN, ISBN, ASIN, or JAN code when listing a product. 

What is Amazon’s Product Variation Policy?

When Amazon sellers search for ASINs, they often come across product variations or parent-child relationships. This “variation relationship” between products means that they are different in attributes such as size, color, pattern, or other characteristics. Typically, the “parent product” is more general, while the “child product” is more specific. Variations are quite common as it allows shoppers to compare between different options and choose the one they like the best.

Below is an example of product variation, in this case, the color.

For each variant product, there are one parent ASIN and child variations. However, Amazon has several rules about listing parent-child ASINs to prevent misuses of variations. The Amazon ASIN variation policy prevents sellers from listing fundamentally different items under the same parent-child ASIN.

Using an Existing Amazon ASIN

If you are a retailer or a reseller, you can most likely use existing ASIN numbers for your product listings. As mentioned earlier, Amazon has a policy against duplicate ASINs, but using an existing identifier for your product also has its perks. Matching to an existing product instead of creating a duplicate listing allows you to benefit from buyer interest and traffic for that product.

When you create a listing through your Seller Central account, you can search for existing ASINs by typing a product’s name, model number, UPC, EAN, or ASIN if you already know it.

Once you get the result, choose the listing you want to sell your products under, and add the remaining information. If multiple ASINs appear, choose the one which features the most product details. However, when you select the ASIN for your product, make sure it is an exact match. Otherwise, the customer’s order might not match the one they receive. As a result, they may leave a negative review, which can be very damaging to your store’s performance rating.

How to Create A New ASIN?

If your new item does not match with an existing ASIN, you must create a new ASIN to include in the Amazon catalog. Typically, manufacturers and brand owners do this, but the chances are that you have found a new product with very little competition. This may also boost your chances of winning the Amazon Buy Box and increasing your profits.

To create a new ASIN, navigate to the “Add Product” tool on your Seller Central account. Creating a new ASIN varies depending on the product category, and in this case, we use adding new soaps as an example. Seller Central > Catalog > Add Products

Choose that you want to add a product that is not sold on Amazon.

Select or search for the category.

At first, there are the main categories. When you click on any type, other categories will open. This procedure goes on until the desired one appears. For instance: Beauty & Personal Care › Skin Care › Body › Cleansers › Soaps. Or, you can simply search for soaps.

Once you select the category, this page appears, and there are some required fields.

Fill the blanks and just click on ‘Save and Finish.’

Once you submit the form, Amazon assigns your product an ASIN code and publishes a product details page. However, keep in mind that similarly as you need to use existing ASINs, other sellers can also now use the ASIN that you just created.

How to add unique Amazon ASINs with UPCs, ISBNS, GTINs, and EANs?

If you’re creating a new ASIN, you’ll need to know your product’s GTIN (Global Trade Item Number). Amazon uses these 14-digit product identifiers to create and match the ASINS. They are located near your product’s barcode. If you do not know the codes, contact your manufacturer, or register a code if you are one.

Common GTINs are EANs, UPCs, and ISBNs:

EAN (European Article Number): 12 or 13 digit identification code.

UPC (Universal Product Code): 12 digit code used extensively for retail packaging in the United States.

ISBN (International Standard Book Number): 10 or 13 digits exclusively for books.

Amazon ASIN Requirements

Amazon has a few restrictions on adding an ASIN, especially if you are a new seller. Until you have established a proven sales record on Amazon, you can create only a limited number of new listings. In other words, as your Amazon sales increase, so does your capacity to create new ASINs. For this reason, you should prioritize the products you are listing to increase sales as fast as possible.

Final Thoughts

Amazon ASIN is a crucial part of successful sales. Identifying a proper identifier allows your customers to find your products, and you can sell more efficiently on Amazon.

However, continuously growing product catalog means that Amazon has become an extremely competitive marketplace to sell on. Sourcing new products and creating entirely new ASINs is one way to avoid direct competition and increase the chances of winning the Buy Box. Unfortunately, this happens rarely, and success is not guaranteed. The best strategy to win your spot on the Buy Box is to utilize AI-powered repricing and increase your profits with dynamic pricing.
