To use Claude Code, you must have an active paid plan. Most individual developers choose:
Claude Pro ($20/mo): Ideal for daily coding and standard projects.
Claude Max ($100 - $200/mo): For power users needing 5x to 20x higher usage limits for massive codebases.
Deposit USDT: Open your Coinepay App, go to Wallet, and deposit at least $25 USDT (to cover the $20 subscription + a $1 authorization hold).
Issue a Premium Card: Select the "US High-Success Rate" card type (usually a 5561 or 5596 BIN). These card segments are highly trusted by Stripe (Anthropic's payment processor).
Note Your Details: Keep your 16-digit card number, CVV, Expiry, and the provided US Billing Address ready.
Anthropic is very sensitive to IP address locations.
Residential US IP: Use a high-quality US proxy. If your IP is flagged as a "Data Center," the payment will be declined even with a valid card.
Browser Cleanup: Use Incognito Mode to ensure no previous regional cookies interfere with the transaction.
Log in to Claude.ai.
Click "Upgrade" or go to your Settings > Billing.
Enter Payment Info: Input your Coinepay card details.
Billing Address: Use the Exclusive US Billing Address provided by the Coinepay App.
Tip: Using a tax-free state address (e.g., Oregon or Delaware) provided by Coinepay can save you the ~$2.00 sales tax.
Confirm: Once the $1 verification passes, your account is upgraded to Pro/Max status.
Once your web account is upgraded, you can activate the developer tool:
Install Claude Code: Run the installation command in your terminal:
Bash
npm install -g @anthropic-ai/claude-code
Run & Login: Type claude in your terminal.
Select Authentication: Choose "Claude account with subscription" when prompted.
Authorize: Your browser will open a page asking you to authorize the CLI. Once you click "Authorize," your Claude Code is ready to use with your Pro/Max limits.
Avoid "Brute Force" Clicking: If the card is declined once, do not keep clicking "Subscribe." This will flag your account. Instead, change your IP node and try again after 24 hours.
Match your IP to Billing: Try to use a US proxy that matches the state of your Coinepay billing address (e.g., if your address is in California, use a CA proxy).
Auto-Renewal: Keep a small amount of USDT in your Coinepay wallet. If a renewal fails due to zero balance, Anthropic may immediately suspend the account.
