If you sell a product people love, someone is probably trying to copy it. And for a growing number of US brands, the front line of that fight is Amazon. Fake versions of your product don't just steal revenue, they steal trust: a customer who buys a counterfeit thinks you made something cheap, broken, or unsafe. The good news is that Amazon has built a real toolkit for brand owners, and knowing how to stop counterfeits on Amazon can turn a constant headache into a manageable, mostly automated process.

This guide walks through the layers of protection available in 2026, in the order that actually matters, so you can decide where to focus first.

Why Amazon counterfeits are worth taking seriously

The scale of the problem is genuinely large. Amazon says it identified, seized, and disposed of more than 15 million counterfeit products worldwide in a single recent year, keeping them from reaching customers or leaking back into the retail supply chain. Its automated systems now scan billions of listing attempts and block the overwhelming majority of suspected counterfeits before they ever go live.

That's encouraging, but it also tells you something important: enforcement is increasingly automated, and the brands that win are the ones who feed those systems good data and use every tool available. Passive selling isn't a protection strategy anymore.

Start with Amazon Brand Registry

Everything begins with Amazon Brand Registry. It's free, and it's the gateway to every serious anti-counterfeiting feature Amazon offers. Without it, you have limited control over your own listings, no direct line to enforcement tools, and no eligibility for advanced programs like Transparency or Project Zero.

To enroll, you generally need an active registered trademark in a country where Amazon operates. If you're an early-stage brand that hasn't trademarked yet, that's the first investment to make, because it unlocks nearly everything else. Once enrolled, you gain better control of your product detail pages, access to reporting tools, and the ability to build the layered defense described below.

Add serialization with Amazon Transparency

The most powerful preventive tool for many brands is Amazon Transparency, a serialization program. Here's how it works in plain terms: during manufacturing, you apply a unique, scannable code to every individual unit you produce. Those codes are then scanned at Amazon fulfillment centers to verify authenticity before an item ships to a customer. A counterfeit unit has no valid code, so it can't slip through.

Serialization is affordable at scale, typically costing between one and five cents per unit depending on volume. For a brand losing sales and reviews to fakes, that's a small insurance premium. Transparency also gives you cleaner visibility into your own supply chain and lets shoppers verify authenticity themselves, which builds confidence at the exact moment they're deciding whether to trust you.

Serialization is a concept that reaches far beyond Amazon. It's the same principle behind modern anti-counterfeiting software and product authentication systems, where each item carries a unique digital identity that customers and platforms can check instantly.

Use Project Zero for instant takedowns

Even with prevention in place, some fakes will appear. This is where Project Zero earns its keep. Eligible brands get a self-service tool to search for counterfeit listings and remove them instantly, without waiting on a support queue. Every removal also trains Amazon's automated protections, so the system gets better at blocking similar fakes proactively over time.

There's a catch worth knowing: Amazon requires brands using the self-service removal tool to maintain a high reporting-accuracy rate, generally at least 99%. In practice that means you need to be confident and precise about what you flag. Sloppy or mistaken reports can jeopardize your access, so build a clear internal process for confirming a listing is genuinely infringing before you pull the trigger.

Lock down who can sell your products

Two more tools help you control the marketplace around your brand:

• Brand gating lets Amazon restrict who can list your branded products. Unauthorized sellers must request approval or provide invoices to prove legitimacy, which raises the barrier for opportunists.
• Brand Catalog Lock and related controls help protect your detail pages from unauthorized edits, a common tactic counterfeiters use to hijack a trusted listing.

It's also worth noting a structural change: Amazon is moving away from inventory commingling, meaning seller inventories are increasingly kept separate rather than pooled. That reduces the risk of a genuine unit being swapped for a fake inside the warehouse, though it can add some operational cost for smaller sellers.

Build continuous monitoring into your routine

Counterfeiting isn't a one-time cleanup, it's an ongoing game. The brands that stay protected treat monitoring as a habit: regularly searching for their products, watching for suspicious pricing, tracking new third-party sellers, and reviewing customer complaints that mention quality or authenticity. Negative reviews are often the earliest signal that a fake is circulating.

As your catalog grows, manual checking stops scaling. This is where custom automation and monitoring dashboards pay off, pulling marketplace data together so you can spot and act on threats quickly instead of discovering them weeks later in your reviews.

A practical order of operations

If you're starting from scratch, here's a sensible sequence: register your trademark and enroll in Brand Registry, apply serialization through Transparency to prevent fakes at the source, use Project Zero for fast removals when they slip through, add brand gating and catalog controls to limit who can sell, and finally set up continuous monitoring so nothing catches you by surprise. Layered together, these turn brand protection from a reactive scramble into a durable system.

Where Esipick fits in

Amazon's built-in tools are strong, but they only cover Amazon. Counterfeits also appear on other marketplaces, social platforms, and standalone websites, and many brands want a single view of authenticity across every channel. That's where custom technology comes in, from serialization and QR-based authentication to blockchain-backed traceability that follows a product from factory to customer.

At Esipick, we help founders and established brands design brand protection software that extends beyond any single platform, combining the practical playbook above with custom tooling built around your supply chain. Our sister venture Esipick AI brings AI-powered detection and monitoring into the mix, helping surface suspicious listings and patterns faster than manual review ever could.

If counterfeits are eating into your revenue or your reputation, you don't have to fight them one takedown at a time. Book a call with our team and let's map out a protection strategy that fits your brand, your budget, and the channels your customers actually shop.
