Introduction
One of the most frustrating challenges Amazon sellers face is recycled barcode issues. When Amazon flags a product for having a reused or recycled UPC, it can lead to listing suppression, sales disruptions, and even account suspensions. Even worse, if Amazon requires you to create a new ASIN, you risk losing valuable reviews and rankings you’ve worked hard to build.
But don’t worry—there’s a solution! In this guide, we’ll break down why Amazon flags recycled barcodes, how to fix the issue without losing reviews, and best practices to prevent it from happening again.
What Are Recycled Barcodes, and Why Does Amazon Flag Them?
A recycled barcode occurs when a previously used UPC or EAN gets reassigned to a new product. This can happen when sellers purchase cheap barcodes from third-party resellers instead of GS1, the official barcode authority.
Why Amazon Flags Recycled Barcodes:
✅ UPC Doesn’t Match GS1 Database – Amazon cross-references barcodes with GS1. If yours doesn’t match, your listing can be flagged or suppressed.
✅ UPC is Associated with Another Product – If a barcode has been used on a different product, Amazon may link it to the wrong item.
✅ Conflicting Product Information – If multiple sellers use the same UPC for different items, Amazon may remove your listing for violating authenticity policies.
How to Identify If Your Barcode Is Recycled
Before fixing the issue, confirm that your barcode is indeed the problem. Here’s how:
1. Check Your UPC with GS1 🔍
Go to the GS1 Database (https://gepir.gs1.org/) and enter your UPC to see if it matches your brand and product. If it doesn’t, you may have a recycled barcode.
2. Look for Listing Suppression or Errors ⚠️
Amazon will usually notify you if your product has a barcode issue. Check for:
- Listing Suppression Notices in Seller Central → Inventory → Suppressed Listings
- Error Codes (5665, 8572, or 5461) indicating UPC mismatches
3. Check for ASIN Merge or Incorrect Product Mapping 🏷️
If your listing suddenly displays a different product image or title, your UPC may have been merged with another ASIN due to a recycled barcode.
How to Fix Recycled Barcode Issues Without Losing Reviews
Once you confirm a barcode issue, use the following steps to resolve it while keeping your product reviews intact:
Step 1: Contact Amazon Seller Support 📞
Before making any changes, submit a case to Amazon Seller Support:
- Navigate to Help → Get Support → Selling on Amazon → Fix a Product Listing
- Explain the issue: “My listing has been flagged due to a UPC conflict. I need to update my product’s barcode while keeping the existing ASIN active.”
- Provide proof of ownership (brand registry documents, invoices, GS1 barcode ownership)
- Request that Amazon updates the UPC without changing the ASIN
Step 2: Update Your Barcode to a GS1-Registered UPC 🆕
If Amazon allows you to update your barcode, follow these steps:
- Purchase a valid GS1 barcode (https://www.gs1us.org/)
- Edit your listing in Seller Central:
- Go to Manage Inventory → Edit Listing
- Update the Product ID to the new GS1 UPC
- Submit for approval
Step 3: Use a GTIN Exemption If Necessary 🏷️
If Amazon won’t let you update your UPC, apply for a GTIN Exemption:
- Go to Seller Central → Apply for GTIN Exemption
- Choose your brand and product category
- Submit proof that your brand is registered with Amazon
- Once approved, create a new SKU under the same ASIN to avoid losing reviews
Step 4: Request a Category Listing Report to Manually Update UPC 📝
If Amazon rejects your update, request a Category Listing Report:
- Open a support case and ask for “Category Listing Report Access”
- Download the report and manually edit the UPC field
- Re-upload the file to update the listing without losing reviews
Step 5: If All Else Fails, Merge Listings to Keep Reviews 🔄
If Amazon forces you to create a new ASIN, request a listing merge:
- Create a new ASIN with a GS1 barcode
- Open a case and request a merge with the original ASIN
- Provide evidence (same product, same brand, GS1 proof)
- Amazon may transfer reviews to the new ASIN
Best Practices to Prevent Recycled Barcode Issues
To avoid these problems in the future, follow these best practices:
✅ Always Buy Barcodes from GS1 – Avoid third-party barcode resellers; they often sell recycled codes.
✅ Enroll in Amazon Brand Registry – Brand-registered sellers have more control over their listings.
✅ Regularly Monitor Listings for Changes – Check for unexpected product title or image changes that indicate barcode conflicts.
✅ Keep Detailed Records – Maintain GS1 ownership certificates and invoices for future proof.
