Claude Overseas Infrastructure Guide

If you build overseas-facing web projects, you already know the pain: you register for an AI service, get a few days of use, then the account gets banned. It happens to many indie hackers. The usual response is to blame the provider. But the real issue is almost always your infrastructure — a stack of small mismatches that add up to a risk score high enough to trigger a flag.

Here is a complete playbook to make your setup look like an ordinary, stable overseas user. No hype, just steps.

Why Bans Happen

Bans are rarely caused by a single mistake. It is a combination of factors: your timezone, IP address, proxy quality, phone number, payment method, and usage behavior. Each one adds a small amount of risk. When the total crosses a threshold, the system flags you.

The goal is not to be invisible. It is to be boring. A normal overseas user does not switch timezones, does not use a shared proxy pool, and does not push the service to do things it refuses to do.

Step 1: Clean the Device First

If you have ever been banned, your device carries traces. The system stores session files and credentials locally. You need to remove them before trying again.

On macOS, open the home directory and look for a hidden .claude folder. Delete it. Then open the Keychain Access app and remove any saved Claude credentials. Next, go to the app-support directory and search for historical session files using the keyword org_id. Delete everything that matches.

If you are not comfortable doing this manually, there are cleanup scripts circulating in developer communities. But if cleanup fails or you are unsure, the safest move is to switch devices entirely. A fresh laptop or a clean virtual machine removes all doubt.

Step 2: Set the Timezone to Taipei

Your device timezone is a major signal. If you are in Beijing and your phone says Beijing time, but your IP says US West Coast, that is a mismatch. The system notices.

The fix is simple: set both your phone and computer to Taipei time. Taipei is in the same UTC+8 zone as Beijing, so there is zero friction in your daily workflow. On macOS, go to System Settings, disable automatic timezone, and pick Taipei manually. Then disable Location Services for the timezone setting under System Services. Do the same on your iPhone.

This makes your device timezone consistent with a region that is not flagged, while keeping your local time identical.

Step 3: Get a Real US Phone Number

SMS-activation services are cheap and easy, but they are also a common ban trigger. Numbers from these services are often shared across many accounts. They pass registration, then get flagged later during a review.

You need a real US number. One option is Red Pocket, which offers prepaid plans around $30 per year. Another is BeeSIM, an eSIM that can be activated on a Chinese-market iPhone in about 20 minutes. Both give you a genuine number that is not recycled from a mass-activation pool.

As of the source material, these options exist. Do not take the cheap route. Spend the money on a number that behaves like a real user’s number.

Step 4: Fix the Network

This is the biggest factor. Widely shared proxy pools are a disaster. Some users abuse them, and the entire IP segment gets a bad risk score. When you connect from that segment, you inherit the risk.

Option A: rent a US VPS and run your own node. Providers like DMIT or BandwagonHost are commonly used. Note that BandwagonHost requires quarterly billing, so budget accordingly. You can optionally layer your VPS behind a residential IP for extra safety.

Option B: subscribe to a residential-IP membership service. For example, IPEqual has a Max tier that costs roughly the same as a normal VPS. This gives you a rotating pool of clean residential IPs.

Both options cost money. There is no free way to get a clean network. If you are serious about stable access, pay for it.

Step 5: Use a Fresh Gmail

Email is another flag point. Ready-made mailboxes bought from third parties are often tied to suspicious activity. Outlook and similar providers get flagged easily.

Register a fresh Gmail account. Right after signup, upgrade it to Google One Pro. This small paid step makes the account look more legitimate. Do not use an email that has been used for other overseas services before.

Step 6: Payment Method

This is the other biggest factor. Domestic dual-currency cards and most virtual cards fail at direct payment. The system sees the card issuer and flags it.

The best option is a US personal bank account or a US card issued through a US offshore company. This is the most expensive to set up but the most reliable.

The second-best option is a US PayPal account linked to a domestic full-currency card or a Hong Kong card. Tie this PayPal to a US Apple ID for additional consistency.

The lowest barrier is a Singapore physical card. For example, Starryblu offers a physical card that you can activate while temporarily on a Singapore IP. You will need to fill in a Singapore address. The downside is Singapore pricing — the Max 20x tier costs about 100 RMB more per month. As of the source material, check the official page for current pricing and availability.

Gift-card routes exist, and community-compiled alternatives circulate in developer forums. These are less reliable but can work in a pinch. No referral links here — just search for what is current.

Step 7: Behavior After Registration

Your usage pattern matters as much as your setup. Do not rush.

After registration, go Pro immediately. Then wait about three days before upgrading to Max 5x. After another ten days, upgrade to Max 20x. This gradual ramp mirrors how a real user discovers the service and increases usage.

Do not repeatedly push the service to do things it explicitly refuses. If it says no, stop trying. Repeated attempts to bypass refusals are a strong signal.

On KYC: some users have passed with their own passport. This is neutral information — it does not guarantee success, and it is not an encouragement to bypass identity verification. Treat KYC as a normal step and provide honest documents.

Final Checklist

Before you register, run through this list:

• Device is clean of any previous session files
• Timezone is set to Taipei on all devices
• US phone number is real, not from an SMS pool
• Network is a private VPS or residential IP, not a shared proxy
• Email is a fresh Gmail upgraded to Pro
• Payment method is a US card, US PayPal, or Singapore physical card
• Behavior plan is gradual, not aggressive

This stack will not guarantee approval. Nothing does. But it removes the obvious flags and makes your account look like a normal, stable overseas user. That is the best you can do.
