Hi there,

NEET roll number is mandatory for the results. Therefore if you forgot your roll number you can follow the steps below:

• If you know your application number then go to the NTA website
• Click on the NEET admit card option there
• Enter your application number there and download your admit card
• Once you download your admit card you can then see your NEET roll number there
• If you don't remember your application number, then  check your registered email id or mobile phone SMS, as they sent the application number there on the time of registration.

Hope that helped...

Good Luck !!
