The 5 Key Amazon IP Anti-Association Checks Sellers Miss

In recent years, anyone running Amazon stores has likely been troubled by the word “linkage.” Once an account is identified as linked, the consequences range from traffic restrictions to outright account suspension.

After repeated investigations, many sellers eventually discover that the problem often lies in the most basic—and most easily overlooked—factor: the IP environment.

Next, we’ll focus on Amazon store IP anti-linkage detection and break down the five key indicators that the platform pays the most attention to, helping you clearly sort out the details where mistakes are most likely to occur.

1. Is the IP “clean”? IP address lookup is the first step

Amazon will first check whether your IP has any historical risk, such as:

•  Whether it has been used by a large number of Amazon accounts

•  Whether it comes from a high-risk data center or abnormal network segment

•  Whether it has been used by accounts that were reported or suspended

This is where an IP address lookup becomes extremely important. You can start with an online IP check to review the IP’s location, ASN, and whether it belongs to a data center.

Generally speaking: Residential IP > Native IP > Standard data center IP. The closer it is to a real user network, the lower the risk.

2. Is the IP’s geographic location stable?

Many sellers like to switch IPs frequently—today in the U.S., tomorrow in Germany, the day after in Japan. In Amazon’s eyes, this behavior is highly abnormal.

In IP anti-linkage detection, there is a hidden metric called geographic continuity, which includes:

•  Whether the country changes frequently

•  Whether city jumps are abnormal

•  Whether the time zone matches the login time

It is recommended that one account be bound long-term to an IP from a fixed country and fixed region. Don’t “hop around” constantly.

Even for multi-store operations, you should ensure: one store, one IP; one environment, one account.

3. The match between IP and device fingerprint

Many people only change their IP and ignore the browser environment—this is actually a major pitfall.

Amazon doesn’t look at IP alone; it also combines browser fingerprint detection to determine whether actions come from the same person. Commonly collected fingerprint data includes:

•  Browser version and engine

•  Operating system and screen resolution

•  Fonts, language, and extensions

•  Advanced fingerprints such as Canvas and WebGL

If the IP is in the U.S. but the browser language is Chinese and the time zone is in Asia, this kind of IP–fingerprint mismatch can easily trigger risk controls.

4. Whether multiple accounts share the same IP

This is the most easily overlooked factor, yet it carries extremely high risk.

Even if your IP itself is very “clean,” the moment multiple Amazon accounts share the same IP, the linkage risk becomes extremely high.

Amazon’s IP anti-linkage detection will focus on analyzing:

•  How many accounts have logged in from the same IP

•  Whether the login frequency is abnormal

•  Whether there is cross-login behavior

Therefore, whether you’re operating as a team or managing multiple accounts individually, you must ensure: IP isolation + environment isolation. Never take shortcuts.

5. Whether you run checks in advance using fingerprint detection tools 

Truly experienced sellers always perform an environment check before going live, rather than regretting it after an account suspension. With the ToDetect fingerprint checking tool, you can proactively test:

•  Whether the current IP has linkage risks

•  Whether the browser fingerprint is overly “similar”

•  Whether any suspicious parameters are being identified

Many sellers run a browser fingerprint check + IP anti-linkage detection with ToDetect before officially logging into Amazon, minimizing risk as much as possible.

A final word

Amazon’s IP anti-linkage detection isn’t as mysterious as it may seem. It’s essentially repeatedly verifying one thing: are you a normal, independent seller with reasonable behavior?

As long as you develop the habit of regularly performing online IP checks and paying attention to browser fingerprint detection results, combined with the ToDetect fingerprint checking tool, many linkage risks can actually be avoided in advance.

Don’t wait until your account is suspended or traffic is restricted to review your environment—by then, the cost is far too high. Refining your IP and fingerprint environment is the correct long-term approach to running Amazon stores.
