Starting from November 10, 2025, a large number of Claude users reported sudden account bans, particularly among developers using Claude Code. Anthropic's September 2025 announcement of "banning Chinese-controlled companies from using Claude" officially took effect, combined with security incidents exposed in November, leading to further tightening of risk control systems. This article will provide an in-depth analysis of the real causes of Claude account bans, Anthropic's China region policy changes, and offer 5 verified safe usage solutions, including account purchase and API calling paths.
Claude Account Ban Wave Background: Policy Changes & Security Incidents
September 2025: Major China Region Policy Adjustment
On September 5, 2025, Anthropic officially announced a far-reaching policy change: banning all "Chinese-controlled companies" from using Claude services, including API and Web products. Key points of this policy:
Policy Scope:
- Any company with more than 50% Chinese capital control is affected
- Not limited to companies registered in mainland China, including Chinese-controlled subsidiaries in Singapore, the United States, etc.
- Applies to all product lines including API, Claude Code, Web, etc.
- Also restricts "adversarial countries" such as Russia, Iran, and North Korea
Official Reasoning:
Anthropic stated in its announcement that companies controlled by "adversarial countries" face legal requirements that may force data sharing or cooperation with intelligence agencies, posing legal, regulatory, and security risks.
Impact Scope:
- Products like Trae (AI code editor) under ByteDance were discontinued
- Anthropic executives said this affects global revenue of approximately "hundreds of millions of dollars"
- Many Chinese developers using Claude API were forced to migrate
November 2025: Security Incident Triggers Stricter Risk Control
On November 13, 2025, Anthropic disclosed the first documented large-scale AI-driven cyber espionage campaign:
Event Summary:
- Suspected Chinese hackers used Claude Code for automated cyber espionage activities
- Targets involved approximately 30 global organizations across multiple industries
- This is the first documented case of a foreign government using AI tools for fully automated cyber attacks
Subsequent Impact:
This incident led Anthropic to further tighten risk control strategies, particularly monitoring of Claude Code usage. Starting November 10, many Chinese users reported account bans, including:
- Long-term Pro/Max subscribers suddenly banned
- Received "account disabled" emails and automatic refund notifications
- Claude Code users became priority "targets"
🎯 Technical Recommendation: Facing Claude's strict risk control, we recommend obtaining accounts through professional channels or using API alternatives. APIYI apiyi.com platform provides stable Claude API calling services, avoiding account ban risks while offering better prices than official, suitable for developers and enterprise users.
Deep Analysis of Three Core Causes of Claude Account Bans
Cause 1: IP Address and Network Environment (60%+)
IP issues are the primary cause of Claude account bans. Anthropic's risk control system detects and rejects "high-risk IPs" in real-time:
High-Risk IP Types:
-
Shared VPN IPs
- IPs from free VPN services shared by many users
- Already marked as "abuse IPs" or have malicious behavior records
- Claude's risk control system instantly identifies and rejects access
-
Data Center IPs
- IPs from cloud service providers like AWS, Google Cloud, Alibaba Cloud
- Claude strictly detects and blocks access from data centers
- Even paid VPS may be banned due to IP ranges being marked
-
Frequent IP Switching
- Switching from US IP to Japan, Singapore IP in short time
- Unstable network connections causing IP jumps
- Identified as abnormal behavior by AI risk control system
-
DNS Leakage
- Using VPN but DNS requests still expose real location
- Browser fingerprint leaks mainland China location information
- Timezone settings don't match IP address
Real Case:
A user shared:
"I used Claude Pro for half a year, always using a free VPN (US node). On the morning of November 12, I found my account was banned when logging in, received an email saying 'violation of terms of service', automatically refunded $20. Later I found out it was because the VPN IP had been used by too many people and was already blacklisted by Claude."
Detection Mechanism:
Claude's risk control system checks:
- IP address historical reputation records (whether there are abuse or fraud records)
- IP's geographic location consistency (whether it matches account registration and payment information)
- Access frequency and patterns (whether it matches normal human behavior)
- Network environment fingerprint (DNS, WebRTC, browser fingerprint, etc.)
Cause 2: Device Environment and Browser Fingerprint (25%)
Beyond IP, Claude also analyzes device fingerprint and browser environment:
High-Risk Device Characteristics:
-
Chinese-Specific Browsers
- 360 Browser, QQ Browser, Sogou Browser
- These browsers' User-Agent exposes user identity
- Claude may directly mark as Chinese users and ban
-
Operating System Language and Timezone
- System language set to "Chinese (Simplified)"
- Timezone set to "Beijing Time (UTC+8)"
- Browser language preference set to "zh-CN"
-
Browser Plugins and Extensions
- Installed many Chinese browser plugins
- Used translation plugins (like Baidu Translate, Youdao Translate)
- Ad blocker configuration exposes geographic location
-
Device Fingerprint Consistency
- Multiple accounts logging in from the same device
- Device fingerprint associated with banned accounts
- Virtual machine or emulator environment detected
Anti-Fingerprint Detection Tips:
Recommended use of fingerprint browsers (like AdsPower, Migratory Bird Browser):
- Independent browser environment for each account
- Randomize Canvas, WebGL, Audio fingerprints
- Simulate real device hardware parameters
- Avoid multi-account association
💡 Selection Recommendation: If you need long-term stable use of Claude, we recommend purchasing native exclusive accounts (regular/Pro/Max) through ai.daishengji.com. These accounts are registered by professional teams using native IPs with clean device environments, significantly reducing ban risk. The platform also provides membership top-up services to avoid bans due to payment information mismatches.
Cause 3: Shared Accounts and Multi-User Usage (15%)
Claude Code shared accounts are high-risk behavior and easily trigger risk control:
Risk Scenarios:
-
Too Many Workspace Members
- Claude's Team and Enterprise plans have member limits
- Personal Pro accounts added to large workspaces
- System identifies as abnormal usage patterns
-
Multiple Devices Simultaneous Login
- 5-10 people sharing one Claude Pro account
- Logging in simultaneously from different IPs and devices
- Initiating large numbers of API requests in short time
-
Huge Usage Behavior Differences
- Shared account usage patterns extremely chaotic
- Asking programming questions one moment, medical questions the next
- AI risk control system identifies as "bot behavior"
-
Payment Information Mismatch
- Using virtual credit cards or proxy payment to upgrade Pro
- Payment address severely mismatched with IP address
- Triggers anti-fraud system
Real Case:
A developer community organized Claude Pro group purchase:
"Eight of us shared one Claude Pro account, $2.5/month each. It was banned in less than a week. Anthropic sent an email saying 'abnormal multi-device login detected'. Finally $20 was refunded, and all 8 people's work was affected."
Claude Official Detection Mechanism:
- Session Analysis: Same account initiating many unrelated conversations in short time
- Device Fingerprint Association: Detecting whether multiple devices are simultaneously active
- Abnormal Usage Frequency: 24-hour high-intensity usage exceeding normal human behavior
- Payment Risk Assessment: Virtual cards, proxy payments, address mismatches, etc.
🚀 Quick Start: Shared accounts pose extremely high risks. We strongly recommend using APIYI apiyi.com platform's Claude API service. The platform supports pay-as-you-go billing, no subscription required, multiple people can share one API key without triggering ban risks. Prices are more flexible than official Pro subscriptions, suitable for team collaboration scenarios.

Response Measures After Account Ban
Determine Ban Type
Claude account bans are divided into temporary ban and permanent ban:
Temporary Ban:
- Characteristics: Login prompt says "account temporarily restricted", may auto-unban after 24-72 hours
- Reason: Triggered automated risk control (like many requests in short time)
- Handling: Wait for auto-unban, don't frequently try logging in during this period
Permanent Ban:
- Characteristics: Received "account disabled" email, Pro subscription automatically refunded
- Reason: Serious violation of terms of service (like IP on blacklist, device fingerprint associated with banned account)
- Handling: Basically cannot appeal successfully, need to replace account
Appeal Process (Low Success Rate)
If you believe your account was mistakenly banned, you can try appealing:
1. Collect Evidence
✓ Account registration time and usage history
✓ Payment record screenshots
✓ Normal usage conversation records
✓ Network environment explanation (prove using compliant IP)
2. Contact Anthropic Support
Email: [email protected]
Subject: Account Suspension Appeal - [your email]
Content:
- Explain account situation
- Provide usage proof
- Request review
3. Wait for Reply
- Usually takes 3-7 business days
- Very low success rate (especially for Chinese users)
- Even if appeal succeeds, may be banned again
Real Case:
A user shared their appeal experience:
"I used Claude Pro for 4 months, suddenly got banned. I sent an appeal email providing all payment records and usage proof. Received reply 3 days later saying 'detected access from unsupported region', refused to unban. Finally had to buy a new account."
Data Backup Recommendations
Important Conversation Backup:
Before account ban, recommend regularly backing up important conversations:
# Use Anthropic API to export conversations
import anthropic
client = anthropic.Anthropic(api_key="your-api-key")
# Get conversation history (need to manually copy from Web or use browser plugin)
conversations = [...] # Get from Claude Web
# Save as local file
import json
with open("claude_conversations_backup.json", "w") as f:
json.dump(conversations, f, ensure_ascii=False, indent=2)
Claude Code Project Backup:
Regularly push Claude Code generated code to Git repository to avoid losing work due to account ban.
