how to delete the previous registration number in ssc.
Hello Dear,
Once if you have submitted your SSC online application you cannot cancel it. Also the registration fee will not be refunded.So in case if you have made any mistakes while filling form you cannot change them nor can cancel the application. You may need to apply once again using a new mail id and phone number. Login using your 'Registration Number' and 'SSC Registration Password' in the login section of the website. Click on 'Modify Registration' and make necessary changes. Be cautious while editing as entries in the 'Basic Details' tab are allowed modification only once
Good Luck
