Error 990003: Main Image and Product ID Mismatch

Error 990003 occurs when the product ID (e.g., UPC, EAN, JAN, ISBN) provided by a vendor or seller matches that of an existing ASIN on Amazon, but the main image associated with the submission contradicts the existing main image for that ASIN. This typically indicates a mismatch between the product being submitted and the one already listed.

To resolve this issue, ensure the product ID is correct and corresponds with the ASIN’s product. If the ID is correct, update the main image to match the product shown on the ASIN’s detail page or remove the image and resubmit. Common issues arise from reused UPCs or EANs, particularly in industries like apparel.
