Overview

Error 8023 is a common listing error that Amazon sellers encounter when attempting to create or upload a product that conflicts with an existing listing in their catalog. This error typically means Amazon's system has detected that a new SKU submission appears to be a duplicate of a product you've already listed, and it needs you to resolve the conflict before proceeding.

Key Points / What Sellers Need to Know

• Duplicate detection trigger — This error fires when Amazon determines that a product you're submitting looks identical to one you've already created, based on the product identifiers and data provided.
• Insufficient distinguishing data — One of the most common causes is not including enough unique product information to differentiate two separate items in your catalog.
• Shared Product IDs — If you've assigned the same UPC, EAN, ASIN, or other product identifier to two different SKUs, Amazon will flag the conflict.
• Residual listing data — Sellers who previously sold an item and failed to fully delete it before resubmitting under a new SKU will also trigger this error.

Common Causes

There are three primary scenarios that lead to Error 8023. First, the product data you submitted may lack sufficient detail for Amazon to tell it apart from another item already in your inventory. Second, you may have used a Product ID — such as a UPC or EAN — that is already tied to a different SKU in your account. Third, you may be trying to relist a product under a new SKU without having properly removed the original listing. Any of these situations will cause Amazon's system to reject the submission and return this error.

How to Resolve the Conflict

Start by comparing the Product ID of the item triggering the error (referred to as Product B) against the Product IDs you've previously submitted for other listings. If you find a match, you need to determine whether the two products are genuinely the same item or two distinct products. If they are the same product, Amazon does not allow you to sell one item under two different SKUs — you'll need to choose one SKU and stop submitting data for the other, or delete the original SKU before resubmitting under the new one. If the products are actually different, you should update the Product ID on one of them so they no longer conflict, and add additional distinguishing details such as different titles, descriptions, or attributes to make the distinction clear.
