To remove unauthorized seller on Amazon listings, the seller has to break a rule Amazon enforces: selling counterfeits, infringing your trademark or copyright, or changing your detail page without permission. Brand owners report those through Brand Registry’s Report a Violation tools, and eligible brands can also use Project Zero and Transparency. If the seller offers your genuine product, Amazon generally won’t remove them for reselling alone, because US law lets people resell goods they bought. That case is a distribution problem you fix off Amazon.
So the first job isn’t filing a report. It’s working out which of three situations you’re in. I’ll walk through each branch below, with the tool that fits and the evidence Amazon wants. If you’d rather hand the enforcement work to a team, our Brand Registry services cover enrollment and violation reporting.
One caution before anything else. This is general information, not legal advice. Trademark and resale law turns on facts, and the moment you’re thinking about letters or lawsuits, I’d talk to an IP lawyer.
Remove unauthorized seller on Amazon: the decision table
| What the seller is doing | Can Amazon remove them? | Main route |
|---|---|---|
| Selling fakes or knockoffs of your product | Yes, if you can show it | Report Infringement (counterfeit), Project Zero, Transparency |
| Selling your genuine product without your permission | Generally no | Distribution control, MAP policy, supplier tracing |
| Selling genuine product that is materially different | Possibly, as trademark infringement | Lawyer first, then a trademark notice |
| Changing your title, images, brand or variations | Yes, as a store policy violation | Report a Violation (store policy) |
| Using your images or copy on a different product | Yes | Copyright notice for the image or text |
Most brand owners land in the first two rows. Which one you’re in decides everything, and I’d settle it with a test buy rather than a hunch. Guessing is expensive.
Step zero: buy one
When you’re unsure, order the product from the seller you suspect. I’d do this even when you feel sure. Check the packaging, the lot code, the label, the feel of it. Compare it with a unit from your own warehouse.
That order ID does double duty. Amazon’s guide for rights owners and registered agents says a test buy with a valid order ID helps support a seller-level report, and its store policy reporting page lists test buy details as useful evidence too. Without one, you’re asking Amazon to take your word over the other seller’s invoices. Don’t.
Branch 1: the seller is selling counterfeits
This is the branch where Amazon will act, and act hard. Its Anti-Counterfeiting policy says counterfeit sales are strictly prohibited and that Amazon may suspend or terminate the account, dispose of the fake inventory at the seller’s expense and withhold payments.
Report it with the right scope
To report IP infringement through Brand Registry, you need the Rights Owner or Registered Agent role. Brands outside Brand Registry can still file through the Report Infringement form that’s open to all selling partners. Either way, you’ll give the trademark registration number, the type of infringement, the ASINs and the evidence.
Scope matters more than most people expect. I’d slow down here. Amazon describes three levels for trademark reports:
- ASIN level: the product bears your trademark but you didn’t make it, so you report the whole ASIN.
- Seller level: one or more offers on your listing are fake, so you report those offers. Amazon says to expect the listing itself to stay live.
- Detail page: your trademark appears on a page selling something that isn’t yours.
If the fakes are riding on your own listing, pick specific sellers. Report the whole ASIN by mistake and you can take down your own offer with theirs. I’d double-check the seller list every time.
When a notice is accepted, Amazon removes the content and acts against the seller. When it’s valid, Amazon also tells the seller and shares your contact details with them. Expect replies, some of them angry. Don’t answer in kind.
Project Zero, if you qualify
Project Zero lets a brand search for counterfeit listings and remove them immediately, without waiting on a review. The bar is high, and I think it should be. You need to be the rights owner of a registered trademark, to have used Report a Violation in the last six months with at least a 90% acceptance rate, and a track record of using those tools within Amazon’s rules. The tool is free. It’s for counterfeits only, and Amazon says brands must keep at least 99% accuracy to keep access.
That accuracy rule is why I’d never point Project Zero at a reseller of genuine stock. One bad removal is a mark against you.
A pending trademark won’t get you in. If that’s where you are, our guide to Brand Registry with a pending trademark explains what a pending mark does and doesn’t open.
Transparency, if fakes keep coming back
Transparency puts a unique code on every unit. Amazon scans FBA units when they arrive at a fulfillment center, and self-fulfilled sellers supply codes at order confirmation. Units without a valid code fail the check. As of November 2026 there’s no enrollment fee; codes cost $0.05 each up to one million a year, falling to $0.03 and then $0.01 at higher volumes. You need a registered trademark, the rights owner role, a GTIN per product and the ability to code every unit you make, wherever you sell it.
My view: Transparency is the strongest long-term answer to counterfeits, and the most operationally demanding one. It works best when your manufacturer can apply codes on the line. Our page on getting Transparency codes covers whether it’s worth the effort for your catalog.
Branch 2: the seller is selling your genuine product
Genuine-goods resale is the most common reason brands see unauthorized sellers on Amazon. It’s also the branch that frustrates brand owners most, and the one where most bad reports get filed. I get why. It feels unfair.
Why Amazon won’t remove them
Amazon’s own trademark policy for sellers says that not owning a trademark doesn’t necessarily stop someone from selling another company’s product, and that a seller of authentic goods may use the brand name to list them. The legal root is the first-sale doctrine. In Sebastian International v. Longs Drug Stores, the Ninth Circuit held in 1995 that a producer’s right to control distribution doesn’t extend beyond the first sale, and that a reseller who simply stocks and resells the genuine product under its trademark violates no Lanham Act right.
Amazon’s rights-owner guide is just as direct about agreements. It respects exclusive distribution deals and MAP agreements, but says breaking them isn’t IP infringement, and enforcement is between the manufacturer and the resellers. It doesn’t enforce exclusive distribution rights except in countries with laws on selective distribution, and it doesn’t enforce barcode ownership.
So don’t file a counterfeit claim against genuine stock. Amazon warns that repeated inaccurate notices can cost you your submission privileges. Worse, the seller can appeal with invoices, and the Intellectual Property Policy tells sellers to do exactly that. You’d lose the claim and some credibility.
The material-difference exception
There’s a narrow way back in. Courts have held that the first-sale defense doesn’t cover goods that are materially different from what the brand sells. An AIPLA article on unauthorized dealers notes that the difference can be physical or not, such as warranty coverage, and that the Second Circuit also recognises a quality-control exception.
I’d treat this as lawyer territory, full stop. Don’t improvise. Whether your warranty or quality program creates a real material difference depends on how you’ve built it and where you’d sue. It’s not something to assert in a Seller Central form on a hunch.
How to stop unauthorized sellers on Amazon who sell genuine stock
The fix sits in your supply chain, and my advice is to start there before touching Seller Central. Find out where the stock leaks from: test buys, lot codes and serial numbers can trace a unit back to a distributor. Then tighten the contracts. Authorized-reseller agreements, a written MAP or pricing policy and consequences for distributors who sell to unapproved accounts do more than any Amazon report.
Our guide to enforcing MAP pricing on Amazon covers the pricing side in detail, including the antitrust limits.
A word on cease-and-desist letters
Letters to resellers are common. In my view they’re often overused. A letter that claims counterfeiting when the goods are genuine is a weak bluff, and if the seller has invoices, they’ll know it. If you send one, keep it accurate, base it on a contract or a real material difference, and have a lawyer draft it. AIPLA also notes Amazon often won’t disclose who a third-party seller is, so you may not know who to address anyway.
Branch 3: the seller hijacked or changed your listing
Sometimes the problem isn’t the offer but the page. That’s a different fight. A seller edits your title, swaps your images, changes the brand field, or bolts your ASIN into a variation family where it doesn’t belong.
Amazon treats these as store policy violations. Its page on reporting store policy, compliance and safety violations lists “making unauthorized updates to a product detail page” alongside abusive variations, duplicate ASINs and inaccurate product information. You report them through the Report a Violation tool, with the ASIN, the policy issue and any test buy details, and track them in Submission History. Rights-owner status isn’t required for store policy reports, though Brand Registry gives you more weight: Amazon says enrollment brings increased authority over listings with your brand name.
If the hijacker is also selling a fake under your page, that’s Branch 1 as well. File both, separately. Amazon processes one complaint type per notice.
Copied images or copy on a different listing are a copyright issue. You report the specific image or text, and Amazon notes the listing itself may stay live.
Get the foundation in place
Nearly every tool above sits behind Amazon Brand Registry, which is free. You need a registered or pending trademark from an accepted office and your brand name permanently on the product or packaging. Our Amazon Brand Registry guide covers enrollment, and if you’re the one receiving a complaint rather than filing it, fixing trademark infringement on Amazon covers both sides.
One rule I’d stress for anyone tempted to outsource this to a fellow seller: Amazon’s code of conduct bars people with active selling accounts from filing infringement notices as a brand’s agent when it benefits their own account. Doing so can get their account terminated.
How I’d sequence it
Test buy first. Always. Then sort the seller into a branch. Counterfeits get a scoped Report Infringement notice, and repeat offenders push you toward Project Zero and Transparency. Genuine resellers get a supply-chain investigation and a distribution fix, not a takedown. Listing tampering gets a store policy report.
When you work it in that order, your acceptance rate stays high, and that rate is what earns you the stronger tools later.
If you’d like help sorting which branch you’re on and filing the right report, our Brand Registry team can take it on, or you can book a free call.
FAQ
Will Amazon remove an unauthorized seller who sells genuine products?
Usually not. Reselling authentic goods isn’t trademark infringement, and Amazon says breaches of distribution or MAP agreements are for the brand and its resellers to settle.
How do I prove a seller is selling counterfeits?
Make a test buy from that seller and compare the unit with your own. The order ID and your findings go into the Report Infringement notice as supporting evidence.
What is an Amazon hijacker?
It’s a loose term for a seller who jumps onto your listing, often with fake or different goods, or who edits your detail page. Fakes go through an IP notice; page edits go through a store policy report.
Can I use Project Zero against unauthorized sellers?
Only against counterfeit listings. It needs a registered trademark and a strong reporting record, and misuse against genuine resellers puts your 99% accuracy requirement at risk.
Do I need Brand Registry to report a counterfeit?
No, a non-enrolled brand can use the general Report Infringement form. Brand Registry adds search tools, store policy reporting, and eligibility for Project Zero and Transparency.
Should I send a cease-and-desist letter to an unauthorized seller?
Only with a lawyer and a sound basis, such as a contract breach or a genuine material difference. A letter that wrongly alleges counterfeiting rarely works and can hurt your position.
