Overview

Error 100456 is a notification that Amazon has automatically removed a KDP (Kindle Direct Publishing) title from sale due to content policy violations. This error affects sellers and publishers who list books through Amazon's KDP platform, and understanding its causes and resolution steps is essential for maintaining your publishing account in good standing.

Key Points / What Sellers Need to Know

• Automatic Removal — When Error 100456 is triggered, Amazon has already removed the affected title from sale. This is not a warning; the listing is immediately taken down and will remain unavailable until the issue is resolved.

• Combined Review Process — Amazon uses both automated detection systems and expert human reviewers to identify policy violations. This means the decision has typically gone through multiple layers of review before the error is issued.

• Linked Account Risk — The error may apply not just to a single title but to offers linked to a title or an entire KDP account that has been found in violation. Multiple violations on a single account can compound the severity of enforcement actions.

• Appeal Option Available — If you believe the removal was made in error, Amazon does provide a pathway to contest the decision through Seller Central support, referencing the specific error code.

Common Causes of Error 100456

There are several reasons Amazon may trigger this error against a KDP title. The most common cause is that the book's content violates Amazon's content guidelines due to inappropriate, offensive, or illegal material. This can include content that most publishers would consider obviously problematic, but it can also catch material that falls into gray areas depending on Amazon's interpretation of its policies. Intellectual property infringement and plagiarized content are another frequent trigger — if your title contains material that belongs to another author or rights holder, Amazon's systems are increasingly effective at detecting it. Misleading information, deceptive practices, or manipulative content within the book can also result in removal, as Amazon works to maintain buyer trust across its marketplace.
