Hello,

The first six numbers of a hall ticket typically represent:

1. Exam Code – Identifies the type of exam.
2. Year of Examination – Indicates the academic year.
3. Region/State Code – Specifies the exam center location.
4. Institution Code – Represents the school/college.
5. Course Code – Denotes the stream or subject.
6. Unique Candidate Identifier – Differentiates individual students.

The exact format varies by examination board or university.

If you want information about any other thing, please ask your query in more clearer way and explain your question.

Thank you !
