  • Various methods such as web address lookup or using ASIN lookup tools can be used to find an ASIN number. Understanding the differences between other product identifiers like SKU, UPC/EAN, and ISBN is also important.

Understanding ASIN: Amazon's unique identifier

ASINs are the backbone of Amazon’s catalog structure, serving as unique identifiers for every product listed on the platform. These 10-character identifiers play a vital role in tracking inventory, referring to catalog data, and indexing catalog pages for searching and navigating the Amazon website.

No matter your experience level with the Amazon marketplace, it’s important to grasp the concept of ASINs. This knowledge aids in delivering a smooth shopping experience for customers and guarantees precise product listings.

What does ASIN stand for?

ASIN stands for Amazon Standard Identification Number, which is assigned to every product on Amazon’s platform. This unique identifier ensures that customers can easily locate and purchase the right product without confusion.

Ecommerce businesses selling on Amazon must ensure they use the correct ASIN for their products. This identifier is integral to both inventory management and catalog organization.

Why are ASINs important?

ASINs are important because they facilitate product tracking, catalog organization, and search functionality on Amazon. They help both sellers and customers in various ways.

ASINs aid sellers in accurately listing their products, a process that is key to inventory management and compliance with Amazon’s selling policies. For customers, ASINs ensure a seamless shopping experience, making it easy to find and purchase the desired products without any hassle.

How to find an Amazon ASIN number

How to find an Amazon ASIN number

Locating an ASIN is a simple process that can be done in three different ways: by checking the web address, looking at the product detail page, or using ASIN lookup tools. Each method has its advantages and can be utilized depending on your needs and preferences.

Finding ASIN in a web address

One way to find an ASIN is by looking at the product URL on Amazon’s website. The ASIN can be found in the web address following the “/dp/“ part. For example, the URL “” contains the ASIN “B09HR5KSR8” right after “/dp/“.

This method is quick and easy, making it an excellent option for many online retailers, as well as customers.

Locating ASIN on the product detail page

Another way to find an ASIN is by checking the product detail page on Amazon’s website. The ASIN is typically displayed in the product details section of a listing, which can be found near the bottom of the page. This method is useful when you’re browsing products on Amazon and want to quickly locate the ASIN for reference or comparison purposes.

Using ASIN lookup tools

For those who want a more efficient and comprehensive approach to finding and managing ASINs, various free and paid ASIN lookup tools are available. These tools can help you find ASINs for multiple products at once, making it easier to manage your listings and monitor competitor products.

Some popular ASIN lookup tools include Jungle Scout, Helium 10, and AMZScout, each offering different features and functionalities to cater to your specific needs.

Differentiating ASIN from other product identifiers

Although ASINs are fundamental for product identification on Amazon, distinguishing them from other product identifiers like SKU, UPC/EAN, and ISBN is equally important. These identifiers serve different purposes in commerce and are used by various retailers and organizations.


ASIN and SKU are both unique identifiers, but they have different functions when it comes to commerce. While ASIN is assigned by the platform for product identification, SKU (Stock Keeping Unit) is a retailer-assigned identifier used for internal inventory management.


The ASIN and UPC/EAN identifiers differ in their scope and application. ASIN is exclusive to Amazon, whereas UPC (Universal Product Code) and EAN (European Article Number) are global barcode standards used for product identification across various industries.


ASIN and ISBN (International Standard Book Number) both serve as unique identifiers for products, but whereas the ASIN is used for all products listed on Amazon, the ISBN is a unique identifier specifically for books.

Creating new ASINs and managing existing ones

For Amazon sellers, understanding when to create new ASINs, when to use existing ones, and how to manage them effectively is key to success. Proper management of ASINs helps ensure accurate product listings, compliance with Amazon’s policies, and a better shopping experience for customers.

We’ll examine when it’s appropriate to create new ASINs, when to use existing ones, and share some useful tips for their effective management.

When to create a new ASIN

Creating a new ASIN is necessary when you’re adding a unique product to Amazon’s catalog that doesn’t already have an existing ASIN. This could be a completely new product or a variation of an existing product that isn’t yet listed on the platform.

By creating a new ASIN, you ensure that your product is accurately identified and listed on Amazon, making it easier for customers to find and purchase it.

When to use an existing ASIN

Using an existing ASIN is recommended when you’re selling a product that is already listed on Amazon. This helps to prevent duplicate listings and ensures that all sellers offering the same product share the same unique ASIN, allowing customers to easily compare and purchase the desired product.

By using an existing ASIN, you also ensure compliance with Amazon’s selling policies and provide an improved shopping experience for customers.

Managing ASINs for your listings

To manage your ASINs effectively, it’s important to regularly review your product listings for accuracy, update product information as needed, and monitor competitor ASINs to ensure your product is competitively priced.

Additionally, it’s crucial to comply with Amazon’s ASIN policies and use the appropriate ASIN for each product to avoid potential issues and maintain a positive seller reputation.

Navigating Amazon's ASIN policies

Understanding and abiding by Amazon’s ASIN policies is essential for sellers to avoid potential problems and provide an undisturbed shopping experience for customers. Amazon has policies in place to regulate:

  • ASIN creation
  • Product variations
  • Brand protection
  • Other aspects of selling on the platform

We’ll take a look at these policies and what they mean for sellers.

ASIN Creation Policy

Amazon’s ASIN Creation Policy restricts the creation of new ASINs for branded products by sellers who are not directly associated with the brand owners. This policy helps prevent counterfeit sales and protect brands from unauthorized use. To comply with this policy, it's essential for sellers to have an Amazon Seller Central account that is authorized by the brand owners.

To list a product with a protected ASIN, sellers need to obtain permission from the brand, pay an additional fee, and submit recent purchase invoices and other required documentation.

Product Variation Policy

Amazon’s Product Variation Policy outlines the parent-child relationships for variant products, enabling customers to compare and purchase products based on various attributes such as:

  • size
  • color
  • style
  • and more

This policy aims to prevent misuse of variations and ensure a consistent shopping experience for customers. As a seller, it’s crucial to adhere to this policy and accurately represent product variations in your listings.

Brand protection and ASINs

It's important that you protect your brand on Amazon, and registering it with Amazon’s Brand Registry is a crucial first step in this process. Brand Registry offers various tools like brand gating to help limit access to your ASINs and prevent counterfeit sales or unauthorized sellers from listing your products.
