If Gmail rejects your phone or email during account creation, it may be due to security filters, temporary bans, or format errors. Google limits sign-ups from suspicious IP addresses, reused numbers, or domains it doesn’t trust. Using a previously flagged recovery option can also cause issues. To fix this, try a different network, use a unique phone number, or verify your identity through alternate methods. Ensuring compliance with Google’s guidelines can help you create a Gmail account successfully.
