If you're an Amazon seller managing multiple product listings, you’ve likely encountered the need to streamline or consolidate similar or duplicate items. Whether due to changes in packaging, upgrades, or simply optimizing your catalog, understanding how to merge ASINs on Amazon is essential for keeping your store organized and customer-friendly.

This guide walks you through everything you need to know about how to merge two ASINs on Amazon, and how a platform like SellerPickle can simplify and support your ASIN merge process.

What Does It Mean to Merge ASINs on Amazon?

Before diving into the "how," let’s break down the "what."

An ASIN (Amazon Standard Identification Number) is a unique identifier assigned to every product listed on Amazon. Sellers might find themselves with multiple ASINs for essentially the same product due to listing duplication, rebranding, or slight variations.

When you merge ASINs on Amazon, you're consolidating these separate listings into a single, unified product page. This not only improves customer experience by reducing confusion but also combines reviews, sales history, and boosts SEO ranking on Amazon’s search engine.

Why You Should Consider an ASIN Merge

There are several good reasons to pursue a merge ASIN Amazon strategy:

• Improved Visibility: Merging ASINs consolidates sales velocity and reviews, improving organic ranking.

• Enhanced Customer Trust: One strong listing with unified reviews looks more credible than several with scattered feedback.

• Operational Efficiency: Fewer listings mean easier inventory and order management.

• Compliance: Amazon prefers cleaner catalogs, and merging redundant ASINs helps maintain listing compliance.

How to Merge Two ASINs on Amazon – The Right Way

Amazon does not allow sellers to merge ASINs directly through Seller Central on their own in most cases. Here's a detailed process that outlines how to merge two ASINs on Amazon correctly:

1. Check ASIN Eligibility

Before attempting a merge, ensure that the two ASINs you want to merge are essentially the same product. They must:

• Have identical physical characteristics (excluding packaging or branding).

• Belong to the same category.

• Share the same brand ownership or authorization.

Trying to merge unrelated ASINs is a violation of Amazon’s policies and can result in account penalties.

2. Determine the Parent and Child Listing (if applicable)

If the ASINs are variations (e.g., different colors or sizes), you may need to create a parent listing that houses both as children, rather than merging them outright.

3. Submit a Case to Seller Support

Go to your Amazon Seller Central account and:

• Click “Help” at the top right.

• Select “Get Support” → “Selling on Amazon.”

• Choose “Products and Inventory” → “Product Page Issue” → “Merge duplicate listings.”

In the case description, clearly mention:

• The ASINs you want to merge.

• Which ASIN should be the primary.

• Justify why the merge is appropriate (e.g., duplicate listings, product packaging update).

Attach product images and invoices if needed to support your claim.

4. Wait for Approval

After submitting your request, Amazon’s catalog team will review the submission. It may take anywhere from a few hours to several days. If approved, the secondary ASIN will redirect to the primary one, and all reviews and sales data will be consolidated.

Key Mistakes to Avoid When Merging ASINs

As powerful as merging ASINs can be, it's essential to avoid common pitfalls:

• Over-merging: Don’t try to force unrelated ASINs into one listing just to gain reviews or rank.

• Lack of Documentation: Always backup your merge request with product photos, UPCs, and invoices to increase your approval chances.
