Common Issues and Troubleshooting

Issue 1: Verification Code Doesn't Arrive

Possible causes:

  • Wrong service selected (chose "Other" instead of "Claude" or "Anthropic")
  • Incompatible country/region
  • Anthropic's rate limiting or temporary restrictions
  • Number already used for another Claude account
  • Network delays or carrier issues

Solutions:

  1. Verify you selected "Claude" (not "Other") from the service list
  2. Wait 30-90 seconds before concluding failure
  3. Request a new code (avoid rapid repeated requests)
  4. Try a different country/region
  5. Apply for a new virtual number
  6. Check if your internet connection is stable

Issue 2: "This phone number cannot be used" Error

Anthropic may reject certain number types or regions. Try:

  • Switching to a different country/region
  • Using a number from a major carrier region (US, UK, Canada)
  • Waiting a few minutes before retrying
  • Checking if the number format is correct (include country code if needed)
  • Ensuring the number hasn't been previously used for Claude

Issue 3: Email Verification Required Instead

Sometimes Anthropic may require email verification as an additional step:

  • Ensure your email address is valid and accessible
  • Check spam folders for verification emails
  • Complete email verification before or alongside phone verification
  • Some accounts may qualify for email-only verification

Issue 4: Multiple Verification Attempts

If Anthropic requires multiple verification steps during registration:

  • Plan for multiple SMS codes during the process
  • Ensure you have sufficient credits
  • Keep the dashboard open throughout registration
  • Some services allow you to receive multiple messages on the same number

Issue 5: Account Recovery Verification

If Claude later requires phone verification for account recovery:

  • Save the virtual number if the service allows retention
  • Note which number was used for which account
  • Consider using a service with number retention options
  • Be aware that temporary numbers may not be available for long-term recovery
