Dear Student,

According to your query I would like to say that give your mobile number and email id without making a mistake at the time of registration. You can get the registration number by going through the forgot registration option in whatever website you have registered. A link will be sent to you in your email address or mobile number. There must be other option to solve this. Kindly go through the instructions given in the website you have applied for

I hope the information will help you out

Thank You
