Overview

Amazon’s feed validation system flags “Error 8080” when a product listing contains any HTML, CSS, or script markup. The issue typically appears during bulk uploads or when copying content from rich‑text sources, and it prevents the affected listings from going live. Sellers must understand how to locate the offending code and clean their data to keep inventory flowing without interruption.

Key Points

• Plain‑text requirement — All fields submitted to Amazon, such as titles, bullet points, and descriptions, must be plain text with no embedded tags or styling code.
• Typical offenders — Tags like <p>, <br>, <b>, <i> and <strong> are the most common culprits found in product titles or bullet lists.
• Hidden formatting — Copy‑pasting from web pages or word processors often inserts invisible markup that triggers the error.
• Feed report guidance — The feed processing summary pinpoints the exact attribute (e.g., “product_description”) that contains prohibited markup, making remediation faster.
• Bulk‑upload risk — A single stray tag in a multi‑SKU file can block the entire batch, delaying dozens or hundreds of listings.

How to Resolve Error 8080

1. Download the feed report — Access the processing summary in Seller Central; it will list the SKU and attribute where the error occurred, for example, “SKU 12345 – product_description.”
2. Open the flagged field — Locate the exact text in your source file; you might see something like <b>Ultra‑Soft Pillow</b> in the title column.
3. Strip all markup — Remove every opening and closing tag, as well as any CSS snippets (e.g., style="font-weight:bold;"). The cleaned title should read “Ultra‑Soft Pillow” with no brackets.
4. Convert to plain text — Paste the cleaned content into a plain‑text editor (Notepad, TextEdit in plain‑text mode) to ensure hidden characters are eliminated.
