Amazon’s Shifting Rules on Duplicate ASINs: What Brands Must Know

Why Amazon’s Duplicate ASIN Policies Matter

The 2025 updates to Amazon’s duplicate ASIN policies are set to significantly impact brands managing multiple listings. Amazon is strengthening its enforcement to eliminate redundant ASINs that confuse shoppers and skew search results. For brands, understanding these changes is essential to maintaining compliance and avoiding penalties.

Key Takeaways

• 🔸 Amazon is expanding automated detections for duplicate ASINs in 2025.

What Are Duplicate ASINs?

Duplicate ASINs occur when one product has multiple listings within Amazon’s marketplace. These duplicates dilute sales performance and increase operational complexity. Amazon’s stricter controls aim to streamline the platform’s catalog while improving the shopping experience.

To fix duplicate ASINs, brands can proactively identify problematic listings via Amazon Seller Central. Utilize options like ‘Report a Problem’ to merge or delete duplicates.

Risks of Ignoring Amazon's New Policies

Non-compliance with Amazon’s updated policies can result in consequences such as listing suppression or account escalations. The enforcement includes tighter catalog audits and listings flagged for review. Brands should note that ASIN accuracy now directly ties to account health.
