How to Create a New ASIN in Amazon? A Complete Guide

When it comes to navigating the Amazon marketplace, you’ll need to have a robust understanding of its often complex unique systems and terminologies. Among these, the Amazon Standard Identification Number (ASIN) is a key standpoint for sellers - but how do you create a new one? In the following comprehensive guide, we’re going to show you how to create a new ASIN in Amazon, so you can make sure that your products are correctly listed and easily discoverable by customers. Let’s dive in!

What is an ASIN on Amazon?

From advertising on Amazon to understanding the more technical aspects of the platform, being an Amazon seller can be quite a complicated business. So, what’s an ASIN? An ASIN, or Amazon Standard Identification Number, is a unique block of 10 letters and/or numbers assigned to every product listed on Amazon, and this identifier is used to manage inventory and index catalogue pages, allowing customers to easily find and purchase products.

Why are Amazon ASINs Important?

ASINs are vital for the efficient organisation and management of the vast array of products on Amazon, not just because they help in accurately tracking inventory and simplifying product searches, but also in aiding in the analysis of sales data. For sellers, having a unique ASIN ensures that their products are distinct and easily traceable in Amazon's crowded marketplace.

Creating a New ASIN Step-by-Step

Research Existing ASINs

Before creating a new ASIN, check if an ASIN for your product already exists, as duplicate ASINs can lead to listing issues and potential policy violations.

Gather Necessary Product Information

Next, prepare detailed and accurate product information, including title, brand, description, and images. This information is essential for the ASIN creation process.

Access the 'Add a Product' Feature

Next head to your Amazon Seller Central account, go to the inventory section and select 'Add a Product'. This section is where you'll initiate the process of creating a new ASIN.

Follow the Prompts to Create a New Product Listing

The platform will guide you through a series of prompts to input your product details, so you’ll want to ensure that all the information you put in is accurate and complete.

Submit for Review

After entering all details, submit your listing for review. Amazon will then create a new ASIN for your product if it meets all guidelines and doesn't duplicate an existing product.

Understanding Amazon's Guidelines

While the process itself is simple, don’t forget to bear the following guidelines in mind:

Comply with Category-Specific Requirements

Don’t forget that different categories on Amazon may have specific requirements for ASIN creation, so you’ll want to ensure you're familiar with these to avoid listing rejections.

Adhere to Image and Description Standards

Amazon has strict standards for product images and descriptions, so you’ll need high-quality images and detailed, accurate descriptions in order to obtain ASIN approval.

Monitoring and Managing Your ASIN

Regularly Check Your Listing

Once your ASIN is created, regularly monitor your product listing for accuracy and customer feedback; this helps in maintaining a healthy listing that resonates with your target audience.

Update As Necessary

If your product undergoes any changes or if you find areas for improvement in your listing, update your ASIN details accordingly. Keeping your listing current is key to sustained success.

Avoiding Duplicate ASIN Creation

Creating duplicate ASINs for existing products can lead to complications and policy violations, so always conduct thorough research before creating a new ASIN.

Ignoring Amazon’s Policies

Finally, non-compliance with Amazon's listing and ASIN policies can result in listing removal or even - in the worst case scenario - an account suspension, so always stay updated with Amazon’s guidelines.

Elevate Your Amazon Selling Strategy

Overall, the process of correctly creating ASINs is a fundamental aspect of selling on Amazon, and something you’ll want to master if you plan on selling long-term on the platform. To ensure compliance with Amazon’s guidelines - and to avoid inventory mistakes - take time to familiarise yourself with the nuances of ASIN creation.


Can I Use the Same ASIN for Multiple Products?

No, each product listed on Amazon must have a unique ASIN. Different colours, sizes, or variations of the same product also require individual ASINs.

What Happens if I Accidentally Create a Duplicate ASIN?

If you create a duplicate ASIN, Amazon may merge the listings or remove the duplicate. It's important to regularly check for existing ASINs before creating a new one to avoid this issue.

How Long Does It Take for a New ASIN to Be Active on Amazon?

Typically, a new ASIN becomes active shortly after submission if it adheres to Amazon’s guidelines, however the review process can take up to 24 hours, and in some cases, it might require additional information.

Is There a Limit to the Number of ASINs I Can Create?

There's no set limit to the number of ASINs a seller can create. However, Amazon expects sellers to maintain the quality and accuracy of their product listings.

Can I Edit an ASIN After Creating It?

Yes, you can edit certain aspects of your ASIN, like the product description and images. However, fundamental attributes like the product title or brand might require Amazon’s approval for changes.
