CBSE Hall Ticket Number: A unique ID assigned to each candidate for a specific CBSE board examination. It appears on the admit card and is used for exam identification and result checking.
PARNIL Number: A unique student ID assigned by the National Informatics Centre (NIC) for online registration for CBSE exams. It is used during the registration process, not as the exam hall ticket.
They are not the same. The PARNIL number is for registration; the Hall Ticket number is for exam administration.
