Overview

Error 100239 appears when Amazon’s validation system finds that the product title (item_name) and the primary image do not describe the same item. The mismatch halts the listing or update, preventing the SKU from going live. Sellers must correct the inconsistency promptly to avoid delays in inventory activation and sales.

Key Points

• Title‑Image Alignment Required — Amazon’s policy mandates that the text in the item_name field and the main image represent the identical product; a shoe title paired with a handbag photo will trigger the error.
• Automated Detection Engine — The platform relies on machine‑learning algorithms that scan both fields; even subtle differences such as a missing accessory in the picture can cause a rejection.
• Submission Blocked Until Fixed — While the error does not affect account health, it stops any further data upload for the affected SKU until the conflict is resolved.
• Common Causes Include Wrong File Upload — Sellers often select an image from a previous listing or upload a placeholder graphic, leading to a title‑image mismatch.
• False Positives Can Occur — Highly stylized images, unusual angles, or low‑resolution photos may confuse the algorithm, resulting in an error even when the title is accurate.
• Support Path Exists — If the seller believes the listing is correct, a manual review can be requested through Seller Support, provided the SKU, title, and image URL are supplied.

How Error 100239 Occurs

1. Data Submission Check — When a seller uploads a feed or uses the web UI, Amazon extracts the item_name string and the URL of the main image, then runs them through a validation model. For example, a feed entry with the title “Men’s Waterproof Hiking Boots” and an image showing a backpack will be flagged.
2. Content Comparison Algorithm — The model parses keywords from the title and runs image‑recognition on the picture to identify product categories. If the detected category (e.g., “handbag”) does not match the title’s category (“footwear”), the system generates error 100239.
