Hi there. In response to your query, the both of the details are different from each other. You could easily verify the both of the details from the dashboard generated after the payment process completed in the application form process. Also the same can be verified from the receipt generated after payment.

Hope this answer helps; best wishes

Yes. Application ID and application number are same. It is a number that given after your final submission of the application for the exam. But you must not confused with the wrong number.

Also it should be noted that registration number and application number are not same.

Registration number is what you get after successfully registring for the exam. Application number is what you get after the final submission of your application form

Thanks.
