Preflight Checklist
What's Wrong?
This is a problem with Claude general auth — not claude code in specific. But I couldn't find any way to submit a ticket or bug report about your auth.
I launched a Claude Cowork Plugin that is bringing many new users to Claude.
Many of them have problems signing up to a new account, they get stuck on phone verification step.
I tried to create a new account to see what the problem was.
I go the error:
Unable to send verification code to this number. Try a different number or try again later.
Which is a useless error message. I think the problem was that I was reusing a phone number that I had set up on another account. But, the error should say that. I imagine users create an account, then forget about it and then try to create another account with another email and get stuck.
Anyway, I then tried to change the number and I was blocked. Another useless error message saying to try again later — after 1 hour I was still stuck.
This problem has been happening for years. See this reddit thread: https://www.reddit.com/r/ClaudeAI/comments/1rrm52s/phone_number_error_when_signing_up/
There is no way for users to report it so no one fixes it.
What Should Happen?
Useful error messages in the bare minimum. Don't block people for multiple hours after one mistake.

Not sure why the first error happens. Sometimes it seems to be random.
