Overview

Error 100286 is a product listing error that Amazon sellers encounter when submitting book inventory through catalog feeds. This error triggers when a feed designated exclusively for print books contains items with incorrect or unsupported product form codes. Understanding how to resolve this issue is essential for book sellers who rely on bulk feed submissions to manage their inventory efficiently.

Key Points / What Sellers Need to Know

• Print-only feed restriction — The feed type associated with this error only accepts print book listings, meaning any other book format included in the submission will be rejected.
• Accepted product form codes — Amazon recognizes only three valid codes for print books in this feed: BB, BC, and BZ. Any other code will trigger the error.
• Format separation required — Ebooks, audiobooks, and other non-print formats must be submitted through their own dedicated feed channels, not through the print book feed.
• Incorrect mapping can cause issues — Even if your product data is correct, system-level mapping errors between digital or audio book codes and the print book feed can produce this error.

What Causes Error 100286

This error arises when there is a mismatch between the product form value in your feed file and what Amazon expects for print book submissions. The most common cause is including non-print book formats such as ebooks or audiobooks in a feed that is strictly reserved for physical print books. Another frequent trigger is using a product form code that falls outside the three accepted values — BB, BC, or BZ. In some cases, sellers may have their product data correctly categorized on their end, but the feed file itself mixes different book formats together, causing Amazon's system to flag the discrepancy. Additionally, backend mapping issues can sometimes route digital or audio book codes into the print book feed pipeline incorrectly, even when the seller has not made an explicit error.

How to Resolve the Error

Fixing error 100286 requires a systematic review of your feed submission. Start by examining the product form value assigned to each item in your feed file and confirm that it uses one of the three accepted print book codes: BB, BC, or BZ. Next, audit your entire feed to identify and remove any non-print book items that may have been included by mistake. Ebooks, audiobooks, and other digital formats each have their own specialized submission channels and should never appear in a print book feed. Once you have corrected the product form values and removed any non-qualifying items, resubmit the updated feed file. If you believe the original values were correct and the error persists, consider removing the affected product from future submissions and investigating whether a system mapping issue is responsible.
