Hello Kongara,

It'll be helpful if you can provide me with the details of which examination Hall Ticket Number you are querying for.

As without knowing the exact examination, I'll not be able to help you.

Otherwise, Go to the official website of the examination you have appeared for and there will be link like "Forget Hall Number" click on that link and proceed as per the norms.

Hope this helps.

Feel free to contact for any further information!!
