Hello!

As you are to specific as regards to your question but if i understand roughly you want to know your exam hall ticket number,

• The respective number will be printed on your hall-ticket provided by your college.
• If you are given a physical copy (paper) check on that, or if your college provided you with any form of soft copy such as PDF, your number will be mentioned in that PDF.
• Last thing would be maybe as all examinations of degree colleges are conducted online, your college might text you through SMS informing you about the same Examination Hall ticket Number.

If it not about anything above then please revert back with the course you are pursuing and which college you are in etc.

I hope this was helpful, Do revert back if you have anymore questions.
