Many people involved in cross-border e-commerce, especially those operating Amazon or Shopify independent stores, often encounter situations where their accounts are suddenly risk-controlled or even directly suspended.
Many people first assume it is an operational mistake. In fact, platforms determine whether your account is risky through methods such as IP lookup detection and browser fingerprint detection.
Today we’ll explain in detail: how Amazon and Shopify detect your IP, and how you can avoid risks in advance.

Whether it’s Amazon or Shopify, both platforms essentially need to ensure the security of their ecosystem. The main situations they worry about include:
• Multiple account association
• Bulk account registrations
• Abnormal logins (such as frequently switching countries)
• Using low-quality proxies
Therefore, platforms use an IP lookup detection system to determine whether a visitor’s network environment is normal. If your IP environment shows abnormalities, such as:
• The same account switching between multiple countries in a short time
• IP identified as a data center IP
• IP shared by many users
These situations can trigger risk control.
Many sellers are not violating platform rules; instead, the issue often comes from low-quality proxy IPs that cause the platform to detect abnormalities.
Platforms first perform a basic online IP lookup to check your IP attributes, such as:
• Country of the IP
• ISP provider
• Whether it is a data center IP
• Whether it is a proxy IP
• IP historical usage records
For example, if your account was registered in the United States but suddenly logs in from a Russian data center IP, the system will likely mark it as abnormal. Therefore, IP stability and authenticity are extremely important in cross-border e-commerce.
Platforms also conduct deeper IP lookup detection, such as:
• Whether the IP has been used by many accounts
• Whether it appears on blacklists
• Whether it has previous violations
• Whether the IP switches frequently in a short time
If an IP has been used to log into dozens or even hundreds of accounts, it is basically a public proxy IP and can be easily identified by the platform. This is why many people encounter problems soon after using cheap proxies.
In addition to IP, platforms also conduct browser fingerprint detection.
A browser fingerprint is essentially the “digital ID” of a device. It records information such as:
• Browser version
• Operating system
• Screen resolution
• Time zone
These elements combine to create a unique device fingerprint. If the system finds:
• The same device fingerprint logging into multiple accounts
• Or IP and device information do not match
This is why many sellers use fingerprint browsers to isolate environments when operating multiple accounts.
Before officially operating an account, it is recommended to perform a complete environment check.
The simplest way is to use an online IP lookup tool to view detailed information about the current IP, including:
• IP type
• Country location
• Proxy detection results
• Risk score
If the results show:
• Data Center
• VPN / Proxy
• High Risk
It means the IP carries relatively high risk.
Many sellers only look at price when choosing proxies, which is actually a big mistake. Proxy IP quality can be judged from several aspects:
Common IP types include:
• Data Center IP
• Residential IP
• Mobile IP
In general, stability ranking is: Mobile IP > Residential IP > Data Center IP
Cross-border e-commerce usually recommends using residential IPs or mobile IPs.
A good IP should have the following characteristics:
• Not used by a large number of accounts
• No history of violations
• Not listed on blacklists
If an IP is heavily “polluted,” it can easily be identified by the platform.
Platforms prefer stable login environments, such as:
• Same country
• Same city
• Long-term fixed IP
If you log in from the US today, Germany tomorrow, and Japan the day after, it is very difficult to maintain stable operations.
Before logging into your account, you can use professional tools for browser fingerprint detection.
For example, the ToDetect fingerprint checking tool can detect:
• Browser fingerprint uniqueness
• Whether fingerprint leakage exists
• Whether IP and device environment match
• Whether risk characteristics exist
This approach allows you to identify problems in advance and avoid platform risk control.
Many professional teams perform an environment check using the ToDetect fingerprint checking tool before operating accounts to ensure the IP + browser environment is safe.
1. Keep the account environment stable
Avoid frequently changing IPs, devices, or browser environments. Stability is the most important factor.
2. Avoid using public proxies
Many cheap proxies are shared by dozens or even hundreds of users, making them easy for platforms to detect. Choosing high-quality residential IPs is safer.
3. Perform regular IP lookup checks
During operations, you can periodically perform an online IP lookup to check whether your IP has been polluted or marked as risky.
4. Check browser fingerprints
Use browser fingerprint detection tools to confirm that each device environment is independent and avoid account association.
If you want to operate Amazon or Shopify accounts stably in the long term, IP security and device environments are unavoidable topics.
Platforms determine whether visitors are abnormal through IP lookup detection, proxy IP quality analysis, and browser fingerprints. A high-risk or unstable network environment may become a hidden danger leading to account suspension.
It is recommended to first use an online IP lookup to check IP attributes, then use the ToDetect fingerprint checking tool to detect browser fingerprints, and combine this with high-quality residential or mobile IPs to ensure a clean, secure, and stable account environment.
