Hello Aspirant,

See if you have successfully registered yourself from your correct e-mail ID then you  must have received your unique ID either through mail or through SMS so please check out both and also don't forget to check the spam folder of your E-mail. Now if you won't find it then you will have to re-register yourselves using another e-mail address and phone number. So you can do accordingly and this time pleased don't forget to note down the Unique ID generated during the Application process.

I hope this information helps you.

Good Luck!!
