Hello Aspirant.

Hope you are doing well.

If you have lost your NTSE{National Test Search Examination} registration number you should try contacting the authorities through their registered number or the mail id that they have provided on their respective site for the same and wait for their response to get your query solved and tell what you'll have to do next and once they provide you with your registration number please get it noted with yourself.

And I would like to tell that the National Talent Search Examination or NTSE is a national-level scholarship program in the country that identifies students with high intelligence and excellent academic talent.
