Brand Authorization Letter for Amazon: The Complete 2026 Guide (All LOA Types + Templates)
Identify which of the four Amazon LOA types you need, what each must contain, how to request one from the rights owner, and how to decode a rejection.
If you have received a Seller Central notification asking for a brand authorization letter for Amazon, you are not alone, and you are likely confused about which document you actually need. An Amazon letter of authorization from a brand is not one single document. Depending on what triggered the request, you may need a reseller authorization, a private-label ownership declaration, a brand-gating application letter, or an IP enforcement appeal document. Submitting the wrong type leads to rejection, delays, or escalation of an enforcement action, all avoidable mistakes.

Amazon describes an LOA as an agreement between the rights owner and a third-party licensee, which the company may request when verifying a seller's right to use a brand or when reviewing an enforcement appeal. Critically, an LOA for Amazon is not universally required. Amazon's own trademark policy states that not owning a trademark does not automatically prevent a seller from selling another company's products.
So do you need a letter of authorization to sell on Amazon? It depends on your situation. This guide gives you a diagnostic decision tree to identify your exact LOA type, a side-by-side comparison of all four Amazon LOA scenarios, copy-ready templates, step-by-step instructions on how to get a brand authorization letter for Amazon from the correct rights owner, a full post-submission workflow with realistic timelines, and a rejection decoder. Read this before you write or submit anything.
If you are looking specifically for the letters that HMMT CORP issues to its own partners, that policy is set out separately in brand authorization letters for authorized resellers.
What is a brand authorization letter for Amazon (and what it is not)
A brand authorization letter for Amazon is a written document from a trademark owner, copyright holder, or brand owner that gives a named seller permission to use specified intellectual property, sell specified products, or perform brand-related activities on Amazon. Amazon's published guidance identifies it as an agreement between the rights owner and a third-party licensee. It is important to understand what an LOA is not, because sellers frequently confuse it with other documents.
An LOA is not the same as a commercial invoice. An invoice proves a purchase happened; it does not grant permission to use a trademark or authorize Amazon sales. A distributor agreement establishes a commercial relationship but may not explicitly cover Amazon. A Brand Registry role gives an account management access to a brand inside Amazon's system, which is a separate matter from a reseller's authorization to sell products. A reseller certificate or sales-tax document establishes tax status, not intellectual-property authorization.
Amazon's trademark policy also makes clear that Brand Registry is its principal service for managing and protecting enrolled brands. Rights owners can report infringement through the Brand Registry infringement-reporting process. These are internal Amazon tools, and they are not substitutes for a properly issued LOA when one is requested.
The diagnostic decision tree: which Amazon LOA do you actually need?
Amazon does not use one universal LOA process. The right document depends on what triggered the request, who owns the rights, and which Seller Central workflow generated the notification. Before writing or requesting anything, answer these three questions.

Question 1: was it your listing or your account that was flagged? If a listing was flagged, you are most likely dealing with an IP or trademark enforcement appeal, or a brand-gating or restricted-category application. If your account was flagged, you are likely dealing with a seller-account verification request.
Question 2: are you the brand owner or a reseller? Brand owners need to prove ownership and the relationship between their trademark registration, operating company, and Seller Central entity. Resellers need authorization from the brand owner confirming the right to purchase and sell on Amazon.
Question 3: what specific right is Amazon asking you to prove? Amazon may be asking for proof of brand ownership, permission to sell products, permission to use a trademark in listings, supply-chain legitimacy, or authorization to manage a Brand Registry account. Each of these needs a different emphasis in the document.
Amazon's LOA requirements vary by workflow. Read the notification carefully before proceeding. Submitting a generic document when Amazon needs a specific answer to a specific question is one of the most common reasons LOAs are rejected. Understanding what a brand authorization certificate is, versus a full licensing agreement, versus a simple reseller authorization, will save you significant time.
All four Amazon LOA types compared side by side
Here is a side-by-side overview of the four main LOA scenarios Amazon sellers encounter in 2026.

Type 1: seller-account verification LOA. Trigger: Amazon asks for evidence connecting your seller account, company, or brand. The letter must prove the relationship between the brand owner and your exact registered legal entity. Submit it through the verification or account-health case in Seller Central as a signed PDF on brand letterhead, along with any requested corporate documents.
Type 2: brand-gating or restricted-product application LOA. Trigger: you apply to sell a gated brand, category, or product. The letter must prove permission to sell the brand's products, typically for a defined marketplace. Submit via the apply-to-sell or restricted-product workflow. Support it with recent invoices, supplier details, and authorization-chain evidence.
Type 3: IP or trademark enforcement appeal LOA. Trigger: a listing removal, trademark complaint, suspected counterfeit notice, or selling-rights suspension. The letter must prove you have a legitimate right to sell or use the product or mark. Submit through Account Health, the performance notification, or the appeal workflow. Include invoices and a corrective-action explanation.
Type 4: wholesale reseller authorization LOA. Trigger: Amazon asks for supply-chain proof when you buy branded products from a manufacturer or distributor. The letter must demonstrate a legitimate commercial supply chain and permission to resell. This may require both an LOA from the brand owner and documentation showing your distributor is authorized to supply the brand. Amazon's policy materials confirm that invoices or LOAs may be required in appeals to demonstrate the right to sell, and that Amazon reviews submitted documents for authenticity or authorization.
How to get a brand authorization letter for Amazon, step by step
Knowing how to get a brand authorization letter for Amazon starts with reading the exact Amazon request carefully. Do not assume you know what is needed. Identify whether Amazon is asking for proof of brand ownership, permission to sell, permission to use a trademark, supply-chain evidence, or something else entirely. A generic LOA submitted in response to a specific question rarely satisfies Amazon's reviewers.
Step 1: confirm the correct rights owner
The letter must come from the company that owns or controls the relevant rights, not from an unrelated retailer or unauthorized intermediary. Amazon's LOA guidance refers specifically to authorization from the intellectual-property owner. A distributor can issue documentation only to the extent it has authority to grant the relevant rights. For brand-level authorization, the letter should come directly from the brand owner. If you buy through a distributor, you may need both an LOA from the brand owner and documents showing your distributor is itself authorized.
If you are not certain who the rights owner actually is, our guide to verifying who owns an Amazon brand walks through the seller profile, state registry, and trademark checks that answer it in about fifteen minutes.
Step 2: match legal names exactly
The licensee name in the LOA must match the legal entity registered in Seller Central. Check your company name, registered address, country of incorporation, and any seller account or merchant-token information Amazon has requested. A mismatch between a trading name, parent company, subsidiary, and the Seller Central legal entity can cause Amazon to question whether the authorization applies to your actual account.
Step 3: request a complete letter
Ask the brand to issue the letter on official letterhead. It must include the date, the brand owner's legal name and address, your exact legal name and address, the brand name and trademark details, the product categories or specific SKUs and ASINs covered, explicit authorization to sell on the named Amazon marketplace, permission to use brand assets if required, the territory and duration, a verification contact, and the name, title, and signature of the authorized signatory. Amazon identifies letterhead, essential terms, and an authorized signature, digital signature, stamp, or seal as important document components.
Step 4: assemble supporting evidence
Depending on the case, support the LOA with recent commercial invoices, purchase orders and payment records, distributor invoices, proof that your distributor is authorized by the brand, product photographs, trademark registration records, a distribution agreement, corporate-registration documents, a written supply-chain explanation, and a corrective-action plan for enforcement appeals. Amazon's policy materials state that invoices or LOAs may be required in appeals to demonstrate the right to sell.
How to write a brand authorization letter for Amazon: copy-ready template
Understanding how to write a brand authorization letter for Amazon means knowing every required element before you put a single word on paper. Below is a starting framework. Customize it to your exact brand, legal entities, products, marketplace, and Amazon request. Always follow the current Seller Central instructions for your specific case, as they take priority over any generic template.

Use the brand owner's official letterhead. Start with the heading LETTER OF AUTHORIZATION and the date. The opening paragraph should identify the brand owner's full legal name and address, confirm that they own or control the relevant intellectual property, and name the brand and trademark registration numbers if applicable. The next paragraph should name your exact registered legal entity and address, and explicitly state that the brand owner authorizes you to purchase, offer for sale, advertise, and sell the listed products on the named Amazon marketplace. List the products, SKUs, or ASINs covered, because a vague product description is a common rejection trigger.
Include the territory, the authorization start date, and the expiration date or revocation terms. Add a section specifying any brand assets you are authorized to use, such as the brand name, logo, or product images, and limit it to exactly what is needed. Provide a verification contact with a company-domain email and phone number. This person must know who you are and be ready to confirm the authorization if Amazon calls or emails.
Close with the signatory's full name, title, handwritten or digital signature, and company stamp or seal if customary. This structure is consistent with what Amazon describes as acceptable in its published LOA requirements. Note that there is no reliable universal brand authorization letter PDF that works for every workflow. Every submission must be tailored.
What to avoid in your letter
- A letter from someone not authorized to represent the brand
- A generic statement such as "Company X is an authorized partner" with no specifics
- Authorization limited to offline sales when Amazon sales are requested
- A license for a different legal entity than your Seller Central account
- An expired or undated authorization
- A letter covering a different brand, product, or marketplace
- Unsupported exclusivity claims unless the brand has expressly granted them
Private-label and international sellers: special Amazon LOA challenges
Private-label sellers present a unique challenge because the trademark owner and the operating company are often different legal entities. If you own your brand but operate through a company that differs from the one on your trademark registration, you need to document the relationship between the trademark owner, the operating company, the manufacturer, and the Seller Central account holder.
Amazon's LOA guidance notes that where a seller does not have a trademark registration for its own brand in the region where products are sold, Amazon may require a declaration of intellectual-property ownership with a company stamp or signature from authorized personnel. An LOA may be unnecessary if your Seller Central entity is itself the rights owner, but Amazon can still request ownership declarations or corporate documents if account and rights records do not align. Keeping those records aligned is the same discipline we describe in what it means to be an S-Corp consumer products company.
International sellers face additional layers. A letter authorizing sales in one country should never be assumed to authorize sales worldwide, so the geographic scope must be stated explicitly. Address the country in which the trademark is registered, the Amazon marketplace where products will be sold, territorial limits in the distribution agreement, whether the brand has appointed regional distributors, and whether the letter needs to be translated or certified. Confirm that the legal entity named in the letter is the same entity registered in the target marketplace.
After you submit: timelines, brand verification, and the rejection decoder
Amazon does not publish a single universal processing time for every LOA submission. Timing varies by workflow, document quality, case complexity, and whether Amazon contacts the brand for verification. Do not rely on a fixed timeline. Use the deadline or estimated response time shown in your specific Seller Central case or application.
Before you submit, prepare your brand contact. Tell the brand representative that Amazon may send an email or make a verification call. Ensure the contact uses a company-domain email address, knows your exact registered legal name, is familiar with the product and marketplace scope covered in the letter, and can answer consistently with what the LOA says. A verification failure can occur even with an authentic letter if the contact does not respond, cannot identify your company, or contradicts the document.
The rejection decoder
- "Document is not acceptable" — Missing letterhead, signature, date, or essential terms. Fix: obtain a newly issued signed letter with all required elements.
- "Unable to verify supplier" — Amazon cannot confirm the supplier or supply chain. Fix: provide supplier authorization evidence and invoices from a verifiable commercial source.
- "Information does not match" — Legal name, address, product, or marketplace mismatch. Fix: correct the LOA and resubmit documents with identical entity details.
- "Insufficient proof of authorization" — The letter is too vague or does not grant the requested right. Fix: state explicit permission to sell the named brand and products on the named Amazon marketplace.
- "Brand owner could not be verified" — The signatory or company does not appear to control the relevant rights. Fix: obtain the letter from the trademark or IP owner and provide ownership evidence.
- "Invoice does not meet requirements" — Invoice lacks required supplier, buyer, product, quantity, or date information. Fix: request a compliant commercial invoice and submit it alongside the LOA.
- "Appeal denied" — The submission did not address the enforcement reason or lacked evidence. Fix: follow the exact notice, explain corrective actions, and provide targeted authorization and supply-chain documents.
Amazon's policy materials emphasize that LOAs and invoices may be used in enforcement appeals to demonstrate the right to sell, and that Amazon reviews documents for authenticity or authorization.
Version-control log: keep your Amazon LOA submissions organized
Maintaining a version-control log is a simple professional practice that prevents costly mistakes when Amazon requests updated documents or when you need to track the status of multiple submissions. For each LOA submission, record the version number (for example, LOA-2026-01), date received, the brand owner's legal name, your seller legal entity, the marketplace, products or SKUs covered, authorization start and end dates, signatory name and title, supporting invoice file names and dates, Seller Central case ID, submission date, Amazon's response, the exact rejection wording if applicable, your corrective action, the current file location, and the next review date.
Keep the original signed file, the submitted copy, all supporting documents, and Amazon's messages together in one place. Do not overwrite older versions. Retaining an audit trail protects you if Amazon revisits a previously resolved case or if a brand revokes authorization and a dispute arises. This practice is particularly important for sellers operating across multiple Amazon marketplaces, managing multiple brands, or working with distributors who themselves hold intermediate authorization from the brand.

Conclusion
A brand authorization letter for Amazon is not one document. It is a category of documents, each tailored to a specific trigger, a specific rights owner, and a specific Seller Central workflow. Getting the right type, from the right source, with the right legal names, marketplace scope, and verification contact is the difference between a fast approval and a rejection that delays your ability to sell.
Use the diagnostic decision tree in this guide to identify your exact LOA type before writing anything. Match legal entity names precisely, assemble supporting evidence, and prepare your brand contact for Amazon's verification process. Maintain a version-control log so you always know the status of every submission. And remember the two most important rules: an LOA does not guarantee approval, and there is no universal template that works for every case.

Frequently asked questions
Do you need a letter of authorization to sell on Amazon? Not always. Amazon's trademark policy states that not owning a trademark does not automatically prevent a seller from selling another company's products. However, Amazon may request an LOA, invoices, or other evidence when you apply for restricted products, face an enforcement action, or are asked to prove supply-chain authorization.
What is an LOA for Amazon? An LOA for Amazon is a written authorization from a brand or intellectual-property owner that allows a named seller to use specified intellectual property, sell specified products, or perform specified brand-related activities on Amazon.
What is a brand authorization certificate on Amazon? Brand authorization certificate is a common informal term for proof that a seller is authorized by a brand. Amazon's official terminology centers on a letter of authorization or licensing agreement rather than a single universal certificate.
How do you write a brand authorization letter for Amazon? Use the brand owner's official letterhead and include the licensor's full legal details, your exact registered legal name and address, the brand name and trademark details, the products or ASINs covered, explicit authorization to sell on the named Amazon marketplace, the territory and term, a verification contact, and an authorized signature.
Can a distributor issue a brand authorization letter for Amazon? A distributor can issue documentation only to the extent it has authority to grant the relevant rights. For brand-level authorization, obtaining the letter directly from the brand owner is generally stronger. You may need both a distributor's authorization letter and a separate LOA from the brand owner.
Is there a universal Amazon brand authorization letter PDF that works for every case? No. There is no single PDF that guarantees acceptance across every Amazon workflow. Every template must be customized to the exact brand, legal entities, products, marketplace, territory, and the specific Amazon request.
What is the difference between an LOA for account verification and one for an enforcement appeal? An account-verification or restricted-product LOA focuses on whether you are authorized to sell a brand or product. An enforcement-appeal LOA typically requires the authorization letter plus invoices, supply-chain evidence, an explanation of the alleged violation, and corrective actions.
