Existing Product Listing

Simply search for the product using its UPC, EAN, JAN, or ISBN during the listing creation process.
If a match is found, you can use the existing ASIN to sell your product alongside other sellers.
New-to-Amazon Product

Establish a competitive and profitable price point for your product. Factor in manufacturing costs, shipping fees, and Amazon’s selling fees to determine a price that optimizes both sales and profitability.
If your product comes in different variations, such as size, color, or material, you can create a single listing with variations. This allows customers to easily compare options within the same product listing.
The Listing Creation Process

The Magic of ASIN Generation

This ASIN becomes the unique identifier for your product within the Amazon marketplace.

- Seller Tools: For FBA sellers, Seller Central provides tools to search and manage inventory. These tools often display the ASIN number alongside each product listing.
When to Create a New ASIN or Use an Existing ASIN?
Generally, you’ll use an existing ASIN if the product you’re selling is identical in every way to an already listed product on Amazon.
This includes factors like brand, model number, size, color, and any other variations that define a unique product.
For example, if you’re selling a specific blue mountain bike from a recognized manufacturer, and an identical bike is already listed on Amazon with an existing ASIN, you can leverage that ASIN for your own listing.
However, if there are any variations between your product and existing listings, even minor ones, creating a new ASIN is crucial.
This ensures accurate product representation on Amazon and avoids misleading customers. For instance, if the blue mountain bike you’re selling differs from existing listings in that it has a different number of gears or a slightly modified suspension system, creating a new ASIN ensures customers understand exactly what they’re purchasing.
Best Practices for Amazon ASIN Number
Ensure the Amazon ASIN you use accurately reflects the product you’re selling. Double-check for typos or mismatches, as incorrect ASINs can lead to listing issues, order fulfillment errors, and customer dissatisfaction.
If you’re unsure about the appropriate ASIN, contact Amazon Seller Support for clarification.
When creating a new listing, verify that a unique ASIN on Amazon is generated for your specific product variant. Amazon’s system should automatically handle this, but it’s always a good practice to confirm the assigned ASIN before finalizing your listing.
For FBA sellers managing a large inventory, maintaining a catalog organized by ASIN simplifies product tracking and management. Using spreadsheets for inventory management software can further streamline organization by ASIN.
