Ever wondered how “Amazon keeps track” of the millions of products listed on its platform? It’s not just a matter of categories or brand names. There’s a unique identifier at play, quietly working behind the scenes, ensuring every product has its own identity. That identifier is the Amazon Standard Identification Number (ASIN), a seemingly simple code that holds significant power in the world of e-commerce. Whether you’re a seller looking to boost your product’s visibility or a savvy shopper trying to track down that perfect item, understanding ASIN is your gateway to mastering the Amazon marketplace. Let’s explore why this small code makes such a big impact.
What is an Amazon ASIN?
An Amazon ASIN, or Amazon Standard Identification Number, is a unique 10-digit alphanumeric code assigned to every product listed on Amazon. This code serves as a product identifier, allowing Amazon to efficiently manage its vast inventory and ensure that each item is easily searchable and distinguishable from others.
For sellers, ASIN is critical for listing products, tracking sales, and managing inventory.
For buyers, it aids in finding specific products and comparing similar items.
Did you know Amazon started as an online bookstore in 1994? Initially using ISBNs, they soon developed the versatile ASIN system to efficiently manage an expanding range of products, making shopping easier and more organized.
Usage of ASIN for Tracking and Inventory Management
ASINs are integral to how Amazon manages its vast product catalog and inventory. Here’s how they are used:
Product Listing: When a seller adds a new product to Amazon, the ASIN helps identify that product within Amazon’s system, ensuring it’s correctly categorized and easily found by customers.
Inventory Management: ASINs allow sellers and Amazon to track inventory levels accurately. When a product is sold or returned, the ASIN helps update stock levels in real time, preventing over-selling or stockouts.
Search and Filtering: ASINs enable Amazon's search algorithms to display relevant products to customers quickly. They ensure that even with millions of items, customers can find exactly what they're looking for with precision.
Comparison and Recommendation: Amazon uses ASINs to power its comparison features and product recommendations. By associating related ASINs, Amazon can suggest alternative products, accessories, or newer models to shoppers.
Data Analytics: ASINs are also crucial in the backend for data analytics. Amazon analyzes ASIN-specific data to understand market trends, customer preferences, and product performance, helping sellers optimize their offerings.
Order Fulfillment: During the order fulfillment process, ASINs are used to ensure the correct product is picked, packed, and shipped to the customer. This reduces errors and enhances customer satisfaction.
These aspects of ASINs not only help streamline operations but also contribute to Amazon's ability to manage a marketplace of such enormous scale with remarkable efficiency.
Where to Find the ASIN Number on Amazon
Locating the ASIN number on Amazon is crucial for both buyers and sellers, as it serves as a unique identifier for each product. Here's how you can find it:
Product Description and Product Detail Pages
The ASIN is commonly listed in the product details, making it easy to find with just a few clicks.
Product Information Section: Scroll down the product page to the "Product Information" or "Additional Information" section. Here, you’ll see the ASIN listed alongside details like product dimensions, shipping weight, and model numbers. This section is typically located near the bottom of the product page.
Product Description: In some cases, sellers include the ASIN directly within the product description or bullet points. This is especially helpful for products with variations, ensuring that buyers can easily reference the specific ASIN they are purchasing.
On the Mobile App: If you’re using the Amazon mobile app, you can find the ASIN by navigating to the "Product Details" section, which can be accessed by scrolling down the product page. The ASIN will be listed similarly to how it appears on the desktop site.
URL of the Sales Page
Another quick method to locate the ASIN is by inspecting the URL of the product page.
In the URL: The ASIN is embedded in the URL of the product’s page. It typically follows the format “/dp/ASIN/”. For instance, in a URL like “www.amazon.com/dp/B08XYZ1234,” the ASIN is “B08XYZ1234.” This method is especially useful for quickly identifying the ASIN without having to scroll through the product page.
Quick URL Access: If you’re sharing a product link or bookmarking it, the ASIN is a quick reference point. You can copy the URL and immediately identify the ASIN from the link itself, making it easy to share or store for future reference.
Using Third-Party Tools and APIs: Several online tools and browser extensions are available that can extract ASINs from product pages in bulk. These tools are particularly useful for sellers who need to manage multiple listings or compare products across various categories. Tools like Helium 10, Jungle Scout, and ASIN Grabber can pull ASINs along with other key product data, saving time and ensuring accuracy.
Importance of ASINs for Amazon Sellers
ASINs (Amazon Standard Identification Numbers) are fundamental tools for sellers on Amazon. They provide a unique identifier for each product, ensuring smooth operations across various aspects of selling.

How to Create a New ASIN on Amazon
Creating a new Amazon Standard Identification Number (ASIN) is a crucial step when listing a product on Amazon that doesn't already exist in their catalog. Here’s a straightforward guide to get you started:
Using Amazon’s 'Add a Product' Tool
Amazon’s 'Add a Product' tool simplifies the process of creating a new ASIN. Here's how you can do it:
Log in to Seller Central: Start by logging into your Amazon Seller Central account.
Navigate to 'Add a Product': Under the 'Inventory' tab, select 'Add a Product.' This tool allows you to list a new product or match an existing one.
Check Existing ASINs: Before creating a new ASIN, search for your product in Amazon's catalog. If it’s already listed, you should use the existing ASIN to avoid duplicate entries.
If your product is not found, proceed to create a new listing.
Requirement of Product Identifiers like GTINs, UPCs, ISBNs, and EANs
Amazon requires specific product identifiers to ensure the uniqueness and accuracy of product listings. These identifiers include:
GTIN (Global Trade Item Number): A unique identifier used globally to track products.
UPC (Universal Product Code): Commonly used in the United States for product identification.
ISBN (International Standard Book Number): Required for books, ensuring each title is uniquely identified.
EAN (European Article Number): Primarily used in Europe, similar to the UPC.
To create a new ASIN, ensure that your product has a valid identifier. If your product doesn't have one, you might need to purchase a UPC or apply for a GTIN exemption through Amazon.
Steps to Complete the Product Listing
Once you’ve confirmed that your product requires a new ASIN and you have the necessary identifiers, follow these steps to complete the listing:
Step 1: Product Details: Enter essential details such as the product name, brand, manufacturer, and key features. Accurate and detailed information enhances product visibility.
Step 2: Upload Images: Add high-quality images that meet Amazon's image requirements. Good visuals are critical for attracting customers.
Step 3: Set the Price and Quantity: Determine the price of your product and the available quantity.
Step 4: Choose the Category: Select the most appropriate category for your product. This step is crucial for product discoverability.
Step 5: Add Keywords: Include relevant keywords to improve your product's search ranking on Amazon.
Step 6: Save and Publish: Review all entered information, ensuring accuracy, then save and publish your listing.
After completing these steps, Amazon will generate a unique ASIN for your product, making it available for customers to purchase.
Amazon's Product Variation Policy
Amazon's Product Variation Policy is designed to help sellers effectively manage multiple versions of a single product, ensuring a streamlined and organized shopping experience for buyers. Understanding and following this policy is crucial for sellers looking to optimize their listings and improve sales.
Explanation of Parent ASIN and Child ASIN
Amazon’s product variation structure revolves around the concept of Parent ASINs and Child ASINs.
Parent ASIN: The Parent ASIN is a non-buyable entity that acts as a grouping mechanism for related products. It essentially serves as a container for all the variations of a single product. For example, if you’re selling a t-shirt that comes in different sizes and colors, the Parent ASIN would represent the entire t-shirt product line.
Child ASIN: Child ASINs are the individual, buyable products that fall under the Parent ASIN. Each variation of a product (such as a specific size or color) has its own Child ASIN. Continuing with the t-shirt example, each size and color combination would have its own unique Child ASIN. These are the products that buyers see and can purchase on Amazon.
Guidelines for Listing Product Variations
Listing product variations correctly is crucial to comply with Amazon’s policies and to enhance the shopping experience.
Allowed Variations: Amazon allows variations only for certain categories where it makes sense, such as clothing, shoes, electronics, and beauty products. Variations can include size, color, material, flavor, etc. It’s important to check Amazon’s specific guidelines for your product category to ensure compliance.
Consistency Across Variations: All Child ASINs under a Parent ASIN should be consistent and relevant to the variation theme. For example, if your variations are based on size, all Child ASINs should represent different sizes of the same product, without mixing in unrelated features like color.
Accurate Product Information: Ensure that the product title, description, and images for each Child ASIN accurately reflect the specific variation. Misleading information can lead to customer dissatisfaction, negative reviews, and potential policy violations.
Use of Variation Themes: Amazon provides specific variation themes for different categories. Choose the most appropriate variation theme that accurately represents the differences between your products. This helps in organizing the products better and provides a more seamless browsing experience for customers.
Other Product Identifiers: ISBN, UPC, EAN
Amazon uses various product identifiers to manage listings across its vast marketplace. ISBN, UPC, and EAN are some of the most commonly used codes, each serving a specific purpose depending on the product category.
Identifier | Description | Primary Use | Amazon Requirement |
UPC | 12-digit barcode used in North America for retail products like electronics and groceries. Tracks inventory and speeds up checkout. | Retail products in North America | Required for non-book items |
EAN | 13-digit barcode used outside North America, especially in Europe. Similar to UPC, it tracks inventory and manages retail products. | Retail products outside North America | Required for non-book items |
ISBN | Specific to books, ISBN catalogs and identifies books globally. | Books worldwide | Often used as the ASIN for books |
Relation to GTIN-14 (Global Trade Item Number)GTIN-14 is part of the GS1 system, which is a global standard for product identification. It’s a 14-digit number used to identify trade items at various packaging levels. This includes cases, pallets, or individual items, depending on the level of detail needed.
Relation to ISBN, UPC, and EAN: GTIN-14 can include the data from ISBNs, UPCs, and EANs, allowing these identifiers to be standardized across global supply chains. For example, a GTIN-14 might represent a box of books, where each book has its own ISBN, or a case of products where each item has its own UPC or EAN.
Use on Amazon: On Amazon, GTIN-14 is often used for bulk listings or when tracking larger quantities of products. It allows sellers to manage inventory at multiple levels, from individual units to larger shipments.
Difference Between ASIN and SKU
SKU (Stock Keeping Unit): SKUs are internal identification codes created by retailers to manage and track inventory within their systems. They are unique to each retailer and help organize stock at the store or warehouse level.
ASIN (Amazon Standard Identification Number): ASINs are unique product identifiers generated by Amazon when a product is listed on their platform. They are used universally across Amazon’s marketplace to catalog and manage products.
While SKUs are specific to a retailer's internal inventory management, ASINs are Amazon-specific and used for product identification on a global scale.
Aspect | ASIN | SKU |
Full Form | Amazon Standard Identification Number | Stock Keeping Unit |
Purpose | Unique product identifier generated by Amazon | Internal identification code created by the retailer |
Usage | Used to catalog and manage products on Amazon’s platform | Used by retailers to track inventory and manage products internally |
Functionality | Identifies products across Amazon globally | Helps retailers organize and manage stock at the store or warehouse level |
Scope | Universal across Amazon’s marketplace | Specific to each retailer’s inventory management system |
Generation | Automatically assigned by Amazon when a product is listed | Manually created by the retailer based on their internal systems |
Visibility | Visible to both customers and sellers on Amazon | Primarily used by the retailer; not visible to customers |
Integrating tools like SellerMate.ai can help manage both SKUs and ASINs seamlessly, providing a holistic view of your inventory and ad performance
The Benefit of Creating New ASIN Numbers
Creating a new ASIN on Amazon can be a powerful strategy for sellers looking to differentiate their products, increase visibility, and ultimately boost sales. However, it’s important to understand the advantages, strategies, and considerations involved in this process.
Advantages like Exclusivity for Sellers
Creating a new ASIN offers several key benefits, particularly in terms of exclusivity and product differentiation.
Exclusivity and Brand Control: By creating a new ASIN, sellers can establish a unique product listing that is exclusively theirs. This is particularly advantageous for private label products or custom bundles, where sellers want to maintain control over the product’s presentation, pricing, and branding.
Differentiation in the Marketplace: A new ASIN allows sellers to introduce unique product variations, bundles, or enhancements that set their listing apart from existing ones. This differentiation can attract more customers, especially if the product addresses specific needs or offers added value that existing ASINs do not.
Enhanced Product Visibility: With a unique ASIN, the product can be promoted more effectively through targeted marketing campaigns, SEO, and Amazon PPC. This can lead to better visibility in search results, increased traffic, and ultimately more sales.
Strategy to Win the Amazon Buy Box and Increase Sales
The Buy Box is a coveted spot on Amazon’s product pages that can significantly impact sales. Creating a new ASIN can be part of a broader strategy to win the Buy Box.
Control Over Pricing and Promotions: When you create a new ASIN, you have full control over the product’s pricing and promotional strategies. This control is crucial for winning the Buy Box, as Amazon’s algorithm considers factors like price competitiveness, shipping options, and seller performance. By optimizing these elements, sellers can increase their chances of securing the Buy Box.
Minimized Competition: New ASINs can reduce direct competition from other sellers, especially if the product is unique or customized. With fewer competitors sharing the same listing, sellers have a better chance of owning the Buy Box and driving higher sales.
Increased Sales Through Product Bundles: Sellers can create new ASINs by bundling complementary products together. These bundles offer more value to customers, and since they are unique, the chances of winning the Buy Box are higher. Bundling also helps increase average order value, contributing to overall revenue growth.
What is Reverse ASIN Lookup?
Reverse ASIN Lookup is a powerful tool used by Amazon sellers to gain insights into their competitors' strategies, understand product rankings, and optimize their own listings.
