How to Stop Unauthorized Sellers from Listing Your Products on Amazon
Unauthorized sellers on Amazon pose a significant challenge for brands aiming to maintain control over their pricing, reputation, and customer experience. These sellers often list products without permission, undercut prices, and dilute brand value, impacting both profitability and customer trust. For ecommerce managers, marketing leads, and founders, understanding how to effectively combat unauthorized sellers is crucial to scaling successfully on Amazon.
This article provides a comprehensive, strategic guide on stopping unauthorized sellers from listing your products on Amazon. Drawing on best practices and expert insights, it outlines actionable steps to protect your brand, enforce distribution policies, and leverage Amazon’s tools. Incubate Agency, with over 50 years of combined leadership experience in digital and marketplace consultancy, shares proven strategies to help you regain control and accelerate marketplace growth.
Understanding the Unauthorized Seller Problem on Amazon
Unauthorized sellers are third-party sellers who list your products on Amazon without your consent or approval. They may acquire inventory through unofficial channels, such as grey market distributors, or simply resell bulk-purchased stock without authorisation. This can lead to:
Undercutting your pricing and violating Minimum Advertised Price (MAP) policies
Poor customer service and counterfeit or substandard products damaging your brand reputation
Loss of Buy Box control, reducing your sales and margins
Confusion among customers due to inconsistent product listings or branding
Amazon’s open marketplace model allows any seller to list products under an ASIN if the product matches the description, making it difficult to fully prevent unauthorized listings. However, brands can take strategic steps to minimise their presence and enforce control over their listings124.
Step 1: Identify Unauthorized Sellers and Monitor Your Listings
The first essential step is to regularly monitor your Amazon listings to identify unauthorized sellers. This involves:
Checking the “More Buying Choices” section under your product’s Buy Box to see all sellers currently listing your item
Setting up alerts for lost Buy Box notifications, which often indicate aggressive underpricing by unauthorized sellers
Using Amazon monitoring tools such as Helium 10, Jungle Scout, or third-party software to track seller activity and pricing trends
Consistent monitoring helps you stay aware of who is selling your products and spot violations early, enabling timely action14.
Step 2: Establish and Enforce Clear Distribution and MAP Policies
Strong, legally binding agreements with your distributors and resellers are critical to preventing unauthorized sales. Your policies should:
Clearly prohibit resale without explicit brand approval
Enforce strict adherence to Minimum Advertised Price (MAP) guidelines
Include penalties for violations, such as loss of selling privileges or legal action
Require proof of purchase or authorised sourcing for all sellers
Consider implementing product serialization or unique identifiers to track inventory and trace unauthorized stock back to its source. Regular audits of your supply chain and collaboration with trusted distributors help prevent grey market leaks24.
Step 3: Contact Unauthorized Sellers Directly
Once unauthorized sellers are identified, reach out to them promptly and professionally. Your communication should:
Politely but firmly notify them of their unauthorized status
Request immediate cessation of sales or proof of legitimate purchase
Include evidence of your brand ownership and reseller policies
A cease-and-desist letter template can be effective, stating that continued violation may lead to further action. Document all correspondence, as Amazon requires proof that you have attempted to resolve the issue directly before escalating12.
Step 4: Leverage Amazon Brand Registry and Brand Protection Tools
Enrolling in Amazon’s Brand Registry is a foundational step for brand protection. This programme offers enhanced tools to control your listings and combat unauthorized sellers, including:
Access to Amazon’s Report a Violation form for intellectual property infringement
Brand gating, which restricts who can list your products
The Transparency programme, which uses unique codes to verify authentic products
Enhanced search and reporting features to identify listing hijackers and counterfeiters
Brand-registered sellers receive higher priority support from Amazon when reporting violations, increasing the chances of swift resolution14.
Step 5: File Complaints and Escalate with Amazon
If direct contact fails, escalate the issue by filing formal complaints with Amazon. Use the Brand Registry’s reporting tools to submit:
Evidence of unauthorized selling or counterfeit activity
Documentation of your reseller agreements and communications with sellers
Details of MAP violations or other policy breaches
Be thorough and consistent in your reporting to expedite removal of unauthorized sellers. Persistence is key, as Amazon’s enforcement can be slow and sometimes requires repeated follow-ups124.
Step 6: Strengthen Your Amazon Presence and Seller Relationships
To maintain control and reduce unauthorized seller impact, focus on:
Building strong partnerships with authorised sellers who comply with your policies
Working with a single trusted Amazon seller or agency to centralise your marketplace presence
Enhancing your product listings with optimised content, A+ content, and brand storytelling to differentiate from unauthorized sellers
Investing in Amazon advertising and promotions to boost your Buy Box ownership
A proactive approach to brand management on Amazon helps protect your reputation and drives consistent revenue growth43.
