Overview

When Amazon suspects that a product listing may be using a trademark without proper authorization, sellers can be asked to prove they have the right to use that intellectual property. This typically involves submitting either proof of trademark ownership or a Letter of Authorization (LOA) from the trademark holder. Understanding what Amazon expects in an LOA can save sellers significant time and prevent listing suspensions.

Key Points / What Sellers Need to Know

• Trademark scrutiny covers multiple areas — Amazon reviews trademarks appearing on the product itself, packaging, listing images, and the product detail page, not just the brand name field.
• Two acceptable responses exist — Sellers can either demonstrate they own the trademark outright or provide a valid LOA from the rights holder granting permission to use it.
• Five essential terms are required — Every LOA submitted to Amazon must include the licensor, licensee, licensed IP and scope, authorized territory, and duration of authorization.
• Format matters — Amazon accepts LOAs as PDF documents or verified emails from the rights holder's domain, but has strict requirements for each format.
• Invoices and purchase orders won't work — Common commercial documents like wholesale invoices, receipts, and distribution agreements are not accepted as proof of authorization.

What Is a Letter of Authorization?

A Letter of Authorization is essentially a licensing agreement between the owner of intellectual property — such as a trademark, design patent, or copyright — and a third party who wishes to use that IP commercially. The agreement spells out exactly how the licensee may use the property, including what rights are granted, where those rights apply geographically, and how long the authorization lasts. For Amazon sellers, having a valid LOA means you can legally list products using another entity's intellectual property with their documented permission. Without one, Amazon may remove your listings if questions arise about your right to use certain trademarks or branding.

The Five Required Terms in Every LOA

Amazon has established five non-negotiable elements that must appear in any LOA submitted through Seller Central. First, the document must clearly identify the licensor — the company or brand that owns the intellectual property rights. Second, it must name the licensee — the seller or company receiving permission to use the IP. Third, the specific intellectual property being licensed and the scope of rights granted must be defined in detail. Fourth, the authorized territory must be stated, whether that covers a specific country, multiple regions, or worldwide use. Finally, the duration of the authorization must be included, which can range from a fixed period to perpetual rights. Missing any one of these elements will likely result in Amazon rejecting the submission.
