For what case you are talking about is dependent. If you are asking for applying in an examination then you have to register yourself in the website and then only you will get the new id. For that you have to provide a working mobile number and email ID.
Now its a very general answer. If you need to have more specific answer then provide more details about your purpose and repost the question on career360.com (//career360.com) and we will provide you the information as soon as possible.
I hope this answer helps. All the very best for your future endeavors!
