What's Wrong?

Hello Anthropic Support,

I am experiencing issues with both account verification and Claude Code login.

My email address has been verified successfully, and I have also purchased a Claude subscription using my Visa card. However, I am unable to complete phone verification.

Phone number:
+998 97 222 07 19

When I try to verify my phone number, I receive the following message:

"Too many attempts. Wait a few minutes before trying again."

I have already waited and tried multiple times, but the problem still persists.

In addition, when I attempt to log in to Claude Code using my Claude subscription account, I receive the following error:

"Request failed with status code 400"

Since I have already completed payment with my Visa card and my email is verified, I would appreciate it if you could check whether there is any restriction or issue associated with my account or phone number.

Please help me complete the verification process and access Claude Code.

Thank you for your assistance.

Best regards,

Abdilatif Meyliyev

What Should Happen?

I should be able to verify my phone number successfully and log in to Claude Code using my active Claude subscription.
After entering my phone number, I expect to receive a verification code without any errors.
Once my account is verified, Claude Code should allow me to log in normally without displaying the error "Request failed with status code 400".

Additional Information

I am located in Uzbekistan and have already verified my email address successfully.

I purchased an active Claude subscription using my Visa card before attempting to use Claude Code.

However, I am unable to complete phone verification for the phone number +998 97 222 07 19. The system repeatedly shows:

"Too many attempts. Wait a few minutes before trying again."

I have waited and retried multiple times, used different browsers, and restarted the login process, but the issue persists.

Additionally, when attempting to sign in to Claude Code using my Claude subscription account, the authentication process ends with:

"Request failed with status code 400"

Screenshots of both errors are attached to this report.

Please check whether there are any restrictions, verification issues, or account-related problems affecting my phone number or subscription account.
