ssc registration delete account
Dear Aspirant
hope you are doing well
Now let me go through your question
You can not cancel the registration if the modification limit is over, however, what you can try is open a new form and fill it up with another email id or if it doesn't work make some minor changes either your father's name, DOB or your name (father's name seems more safe to me) that has worked for people
But if you don't use you ssc account for a long time then it will consider as inactive user
Hope it helps
Thank you
