Why Amazon Rejects Letters of Authorization
You submitted what looked like a bulletproof Letter of Authorization. The brand signed it. The dates are current. The products are real. And Amazon still rejected your appeal. This scenario plays out for sellers every day, and the root cause is almost never the LOA itself.
Amazon's IP complaint review process does not evaluate authorization letters in isolation. Reviewers check whether the LOA is accompanied by the full evidentiary package that Amazon's Seller Code of Conduct and intellectual property policies require. A standalone LOA, even a legitimate one, rarely clears the bar on its own.
Understanding why your letter was rejected is the first step toward fixing the appeal. The failure modes fall into several distinct categories, each demanding a different remedy. Sellers who work through this process as part of a trademark infringement playbook tend to resolve the complaint far faster than those who simply resubmit the same LOA with a cover note.
The Most Common Reasons a Valid LOA Gets Rejected
The LOA Is Not Specific Enough
Amazon expects a Letter of Authorization to name specific ASINs, product categories, or marketplace regions where the seller is authorized to list. A generic authorization letter that reads "this seller is permitted to sell Brand X products" routinely gets rejected because reviewers cannot verify whether the authorization covers the exact listing under complaint.
Your LOA must specify the marketplace (Amazon.com, Amazon.co. Uk, etc.), the product line or SKUs, and the sales channel. Broad language that a brand attorney might draft for general commercial use often falls short of Amazon's specificity requirements.
The Brand Itself Has No Registered Trademark
Here is a situation sellers frequently overlook. The complainant who filed the IP complaint may not hold a registered trademark at all. Amazon accepts complaints from brand owners even when the trademark is pending or unregistered, but it also requires that authorized resellers prove their authorization against a verifiable brand identity. Running a USPTO trademark search on the brand before you appeal lets you understand exactly what trademark rights exist and whether Amazon's Brand Registry record aligns with the complaining party.
If the brand's trademark is pending or registered under a different entity name than the one on your LOA, that mismatch alone can trigger rejection.
Missing Supporting Documents
An LOA is a declaration, not proof of a commercial relationship. Amazon frequently asks for evidence that the authorization reflects a real, ongoing supply chain. That means invoices from the brand or an authorized distributor, purchase orders, or distributor agreements. Submitting an LOA without at least one form of transactional documentation gives reviewers no way to validate the claim.
evidence checklists that inform professional appeals in this category typically include the LOA itself, brand invoices dated within the last 180 days, a distributor or reseller agreement, and in some cases brand-authorized product authentication documentation.
The Complaint Was Filed Under the Wrong Policy
Not every IP complaint is a trademark complaint. Amazon distinguishes between trademark infringement, copyright infringement, patent infringement, and counterfeit complaints. Each has its own resolution pathway. Sellers sometimes submit an LOA in response to a copyright complaint, which does not require brand authorization at all. Copyright complaints require a counter-notice or proof of license for the creative work in question.
Misidentifying the complaint type leads to the wrong appeal strategy and, almost always, rejection. This is one reason the notice analysis tools is a valuable first stop: it reads the exact notice language, identifies the underlying violation category, and surfaces what Amazon is actually asking for before sellers spend time assembling the wrong evidence.
The LOA Issuer Is Not the Rights Owner
Amazon cross-references the LOA signatory against its Brand Registry database. If the LOA is signed by a distributor rather than the brand's intellectual property holder, or if the brand recently changed ownership, the authorization chain breaks down at the point of verification. Amazon requires authorization traceable back to the registered rights owner, not just any party within the distribution chain.
"Sellers consistently underestimate how thoroughly Amazon validates authorization chains. A Letter of Authorization is a starting point, not a finish line. The evidentiary package that surrounds it determines whether Amazon's review team closes the complaint or escalates it." -- Dr. Mara Finch, Senior Policy Analyst, Kestrel Advisory Group
How to Fix an LOA Rejection and Win the Appeal
Resubmitting the same materials that were already rejected almost never works. The appeal needs to be rebuilt with the gaps addressed directly. Following this structured approach improves reinstatement outcomes significantly, as discussed in the plan of action template guide.
- Diagnose the exact rejection reason. Read Amazon's response carefully and identify whether the rejection cites LOA specificity, missing invoices, trademark verification failure, or a policy mismatch. The rejection language usually hints at the actual gap, even when it is vague.
- Obtain a revised LOA with ASIN-level specificity. Contact the brand and request a new authorization letter that names your seller account, the Amazon marketplace, and the specific ASINs or product lines you are authorized to sell, along with an explicit authorization end date.
- Gather transactional proof of the supply chain. Collect invoices dated within the last 180 days that show the brand name, your business name, the products purchased, and the quantities. If you source through a distributor, obtain a letter from the distributor confirming they are authorized by the brand to sell to resellers.
- Verify the trademark registration and match it to your LOA. Search the USPTO database to confirm the trademark registration status and the name of the registered owner. Make sure your LOA is signed by or on behalf of that exact entity, not a subsidiary, importer, or unrelated licensee.
- Draft a root-cause and corrective-action Plan of Action. Write a clear narrative explaining the original complaint, why the initial LOA submission was insufficient, what steps you have taken to resolve the authorization gap, and what processes you have put in place to prevent future complaints. This is where the Appeal Letter Generator converts a complicated narrative into a structured, policy-specific document that addresses each of Amazon's required elements in the correct order.
- Assemble the full evidence package and cross-reference the checklist. Organize every document into a single, clearly labeled submission. Include the revised LOA, invoices, distributor agreement (if applicable), the POA, and any trademark verification screenshots.
- Submit through Account Health and monitor the response. Upload your appeal via Seller Central's Account Health dashboard. After submission, watch for Amazon's reply closely. If Amazon responds with a request for additional information or a partial approval, the Response Analyzer helps sellers understand exactly what the response means and what the recommended next step is.
