As soon as you share your email ID during your account opening journey, you get a verification email. We recommend that you check that email and verify your email ID through the link provided in the email right away. However, you can choose to continue with your application and verify the email ID later as well. But you know what?  You cannot finish your account opening process until you verify your email ID. So, it will be great if you do it as soon as you receive the verification email.
