Overview

Sellers encounter Error 8055 when a bulk upload or product data feed contains an ASIN that Amazon’s catalog does not recognize. The issue stops the feed from processing, delaying the appearance of new listings and potentially hurting sales velocity.

Key Points

• Error trigger — The system returns Error 8055 whenever the ProductID column holds an ASIN that cannot be matched to an existing catalog entry.
• Common sources — Typos, deactivated ASINs, or mistakenly placing a UPC/EAN in the ASIN field generate the same rejection.
• Affected uploads — Flat‑file templates, Inventory Loader files, and any third‑party feed that uses ASIN as the identifier are vulnerable.
• Quick validation — Enter the 10‑character code in Amazon’s search bar; a live product page confirms validity, while a “no results” page signals an invalid entry.
• Typical symptom — The error message lists the SKU that failed, often accompanied by a line such as “ProductID value is not a valid ASIN.”
• Impact scale — A single bad ASIN stops the entire file from processing, so large catalogs can lose dozens or hundreds of SKUs in one submission.
• Resolution path — Replace the offending ASIN with a verified one, or create a new listing if no matching ASIN exists, then re‑upload the file.
• Preventive tip — Incorporate a pre‑upload ASIN check (e.g., a simple macro or script) to catch formatting errors before they reach Seller Central.

How to Resolve Error 8055

1. Identify the flagged SKU — Open the error report, locate the SKU referenced in the “ProductID” line, and note its row number in the original spreadsheet. For example, SKU “ABC‑123” appears on row 57 with the problematic ASIN.
2. Extract the current ProductID value — Copy the ASIN shown in the ProductID column for that SKU; it might look like “B00X9Z9Y5”.
3. Confirm ASIN status — Paste the copied code into the Amazon.com search bar. If the search lands on a product detail page, the ASIN is active; if it returns “No results” or unrelated items, the code is invalid.
