Duplicate ASINs make product searches and purchasing decisions difficult for customers. Creating duplicate ASINs is a violation of Amazon’s listing policies. If you have ASINs in your inventory that match other ASINs on Amazon, you can inspect them in the Potential Duplicates page and avoid suppression by accepting or rejecting it as duplicate.

To avoid suppression of your ASINs identified as potential duplicates, follow these steps:

1. Go to Inventory > Manage Inventory in Seller Central.
2. Click Potential Duplicates at the top of the page.
3. Click the Review Duplicates button for an ASIN.
4. Read the instructions on the top of the page and review your ASIN with its potential duplicate.
5. Select the appropriate button at the bottom of the page to confirm whether your ASIN is a duplicate or not.
6. Repeat the procedure for remaining ASINs.

When Amazon identifies a potential duplicate ASIN, we will add the ASIN to the Potential Duplicates page in Manage Inventory. From the date an ASIN starts showing up on the Potential Duplicates page, you have 30 days to review and respond by following the steps above. If you do not provide a response on an ASIN on the Potential Duplicates page within its 30-day grace period, the ASIN will be suppressed from the search as a duplicate. Once an ASIN is suppressed, the ASIN will not show up on the Potential Duplicates page. You can view all suppressed ASINs on the Suppressed page.

To reinstate an ASIN that has been suppressed as a duplicate, follow these steps:

1. Go to Inventory > Manage Inventory on Seller Central.
2. Click Suppressed at the top of the page.
3. Select any ASIN that says “click Review Duplicates to avoid suppression” in the Issue(s) to fix column to see ASINs with potential duplicates. You can also click Duplicate in the Filters to locate ASINs suppressed as duplicates.
4. Click the drop-down icon next to Edit, and then click Review Duplicates.
5. Read the instructions on the top of the page and review your ASIN with its potential duplicate.
6. Select the appropriate button at the bottom of the page to confirm whether your ASIN is a duplicate or not.
7. Repeat the procedure for remaining ASINs.
