Issue with Amazon account when using Residential/ISP proxies

Hi everyone, I’m managing several Amazon accounts for cross-border marketing project using an anti-detect browser and ISP proxies. However , I'm frequently hitting “Identity Confirmation” checkpoints shortly after setup. Is this likely a proxy quality issue or a fingerprint mismatch? Looking for advice on the most “trustworthy” setup from Amazon perspective.

It could be any number of things. Depends on the proxy, payment method, personal info. Could be anything

Maybe there’s a mismatch because amazon doesn’t just check IP or browser, it also looks at location, payment info, and activity. Keeping everything consistent is the best way to avoid account checks.

Difficult to tell. it can be because of a lot of reasons.

This is likely a combination of both proxy and fingerprint issues. Amazon's system heavily distrusts residential/ISP IPs that are overused or flagged. Even with good proxies, fingerprint mismatches (like inconsistent timezone or WebRTC leaks from your anti-detect browser) can trigger the check. For maximum trust, ensure your proxy IPs are clean, low-usage, and geographically stable, and double-check that your browser profile perfectly matches the proxy location with all leaks plugged. Consistency is key.

Consistency is key.t, thanks. I’ll try to find some cleaner proxies.

Okay, thanks. I’ll try to find some cleaner proxies.

Usually it’s not just proxy quality. From Amazon’s perspective, checkpoints often trigger when IP geo, timezone, language, and device fingerprint don’t form a consistent profile or the account lacks trust history. You need to focus on fingerprint realism and stability: use an antidetect browser that produces coherent, high-authenticity fingerprints, keep IP stable, choose clean residential/ISP IPs matching the account country, align all environment signals, and warm up activity gradually.

I completely agree with the previous comments that it's likely a combination of both proxy and fingerprint issues. Consistency is indeed key when it comes to avoiding Amazon's identity confirmation checkpoints. Have you considered using a proxy provider that offers IP rotation and geotargeting options to help maintain a stable and consistent location? Additionally, are you using any specific tools or plugins to ensure your anti-detect browser is properly configured and not leaking any sensitive information?

It’s probably not just the proxy. Amazon looks at the whole picture, fingerprint consistency, location matching, and how the account behaves right after signup.

Most likely fingerprint mismatch, not just proxy quality. Amazon checks consistency - IP geo, timezone, language, browser environment all need to align.

If you’re getting identity checks right after setup, it’s usually not just proxy quality. Amazon’s system builds a trust score from multiple signals at once IP history, device consistency, geo alignment, and behavior patterns.


Even small mismatches (timezone vs IP, browser language vs marketplace, switching environments too fast) can flag the account early.


From Amazon’s perspective, stability > sophistication. The more variables you rotate, the less ‘real’ it looks. Long-term survival usually comes down to consistency and clean separation between accounts rather than just better proxies.

to avoid frequent Amazon account suspensions while using anti-detect
browsers and ISP proxies, ensure100% isolation by assigning a unique,
high-quality residential IP, distinct browser fingerprints (user-agent
time zone), and separate browser profiles/cookies for each account

It’s usually not just the proxy. Amazon looks at the whole picture.

If you’re getting identity checks right after setup, something is not aligned. IP location, timezone, browser language, marketplace country or even payment details can trigger it.

From Amazon’s perspective stability matters more than tricks. One account should have one stable IP. No switching mid session. All geo signals should match the account country. And don’t rush activity on a fresh account.

The more things you rotate, the less natural it looks. Consistency is what keeps accounts alive.

Frequent Amazon identity checks usually come from inconsistent fingerprints, proxy issues, or unusual account behavior. Using stable IPs, consistent device settings, and normal activity patterns helps reduce checkpoints.

amazon is one of the stricter platforms when it comes to trust scoring so getting identity checks early usually means something in the environment stack isn't aligned properly, not just the proxy itself.

a few things worth checking beyond what's already been mentioned here:

1. payment method geo needs to match the proxy location. if you're using a US ISP proxy but the card or billing address is from a different country, that alone can trigger verification. amazon cross references payment signals with IP location more aggressively than most platforms.

2. ISP proxies are generally better than rotating resi for amazon because you get a stable IP tied to a real ISP, but even then if the specific subnet has been heavily abused by others you're inheriting that risk. check the ASN reputation before committing to a provider.

3. don't skip the warm up phase. fresh account + new device fingerprint + immediate high value actions is the fastest way to get flagged. browse around, add stuff to cart, read reviews, act like a normal buyer for a few days before doing anything that involves money or sensitive account changes.

4. one thing people overlook is the DNS resolver. if your proxy says you're in new york but your DNS queries are resolving through a server in germany, that's a mismatch amazon can see. make sure DNS is going through the proxy or at least through a resolver in the same region.

consistency across every signal is what keeps accounts alive long term.
