Error FAQ: Duplicate Barcode at Target+
A common error when listing products on Target+ is the "duplicate barcode" error. This guide explains what it means and how to resolve it.
Why am I seeing the error "The item's barcode duplicates an existing Target core product.: Barcode"?
This error means the barcode (UPC/GTIN) for your product already exists in Target's internal product catalog.
This is usually because the item has a history with Target in one of the following ways:
In-Store (1P): The product was previously sold directly by Target in their physical stores.
Drop-Ship (2P): The product was previously sold on Target.com through their drop-ship vendor program.
Existing Listing: In rare cases, another third-party seller has already listed your exact product on Target+.
How do I fix this?
Because the issue is within Target's internal catalog, it is outside of Acenda's control. You must contact Target support directly to resolve it.
Follow these steps:
Log in to your Target Partner Portal.
Navigate to the support section and open a new support ticket.
In the ticket, clearly explain the issue. State that you are receiving a "duplicate barcode" error for a specific product and provide the barcode number.
Request that Target's support team investigate and resolve the conflict so you can list your product.
