Understanding Amazon Error 8573: What to Do When Your Product Listing Matches an Existing ASIN
Error 8573 occurs when Amazon detects potential ASIN matches for a product you are trying to list. Sellers must search the catalog for existing listings first, and contact Seller Support with the error code if a new ASIN is genuinely needed.
Overview
Error 8573 is a listing error that Amazon sellers encounter when attempting to create a new product listing that Amazon's catalog system believes may already exist. This error serves as a safeguard against duplicate ASINs in Amazon's marketplace, but it can be a frustrating roadblock for sellers trying to add legitimate new products. Understanding how to resolve this error efficiently can save sellers significant time and prevent unnecessary delays in getting products live.
Key Points / What Sellers Need to Know
- What triggers the error — Error 8573 appears when Amazon's catalog matching system detects that the product you are trying to list may already have an existing ASIN in the catalog. This typically happens during flat file uploads or when adding products through Seller Central.
- It is a prevention mechanism — Amazon uses this error to reduce duplicate listings in its catalog, which helps maintain data quality and a better customer experience across the marketplace.
- Search the catalog first — Before attempting to create a new listing, sellers should thoroughly search Amazon's existing catalog to determine whether their product already has an ASIN assigned to it.
- Seller Support can help — If your product genuinely does not exist in the catalog and requires a new ASIN, you will need to contact Amazon Seller Support directly and reference error code 8573 to request manual resolution.
How This Error Works
When a seller submits product data to create a new listing, Amazon's backend systems automatically compare the submitted information against existing catalog entries. If the system identifies potential matches based on attributes such as product title, brand, UPC, EAN, or other identifying information, it blocks the new listing creation and returns error 8573. This automated matching process is designed to prevent the proliferation of duplicate ASINs, which can fragment reviews, confuse customers, and create catalog quality issues. The error message directs sellers to first search the existing catalog and, if no match is found, to contact Seller Support for assistance in creating a new ASIN.
