Duplicate Item Already Exists

Another seller has already created this item on Walmart's catalog. You should match to the existing item ID instead of creating a new listing.

Walmart maintains a single catalog. When a GTIN already exists, new submissions with conflicting titles, attributes, or images are rejected as duplicates. Walmart wants all sellers offering the same product to share one detail page (similar to Amazon ASINs) rather than creating parallel listings.

1. Search Walmart.com for the existing item using the GTIN
2. Use the Match Item flow in Seller Center to attach your offer
3. Submit only price, shipping, and inventory (not catalog content)
4. Request content updates via the Content Dispute process if needed
5. Remove the duplicate submission from your feed

• Submitting variants as separate parent listings
