Hello Aspirant,

Since you have not mentioned the name of examination for which you want to retrieve your registration number and Hall ticket number so it is quite difficult for us to guide you with an accurate information but commonly if you register for any entrance examination or competitive examination the registration number is sent to your registered mobile number through SMS and also on the e-mail ID of candidate so you can check those once and for Hall ticket number you can login to your application using the above registration number and other credentials required and you can download another copy of Hall ticket from there.

I hope this information helps you, if not then kindly help us with the exact name of application.

Good Luck!!
