As an AI tool user, Claude login and subscription issues can be frustrating. This article focuses on common scenarios for international users, compiling core solutions for login failures, subscription errors, and account security—without complex technical terms, just actionable steps.
Login Failure: Verification Code & Network Diagnosis
When logging into Claude, encountering "verification code not received" or "login timeout" is often related to your network environment. Start by checking if your proxy tool is set to global mode, and try switching to a US or Japan node.
If the verification code email is delayed, check your spam folder and add noreply@anthropic.com to your whitelist. If you use Gmail or Outlook, some domestic email providers may cause delays—consider switching to an international email service to re-register.
Additionally, if you get logged out frequently or see a "session expired" message, it may be due to the account being used on multiple devices at once. Go to settings to log out of other devices, and change your password regularly.
Subscription Issues: Payment Failure & Card Not Charged
Claude Pro subscription requires a credit card that supports international payments or a PayPal account. Common payment failure reasons include: the card not having overseas payments enabled, bank fraud prevention blocking the transaction, or a mismatch between your billing address and IP.
