Hello aspirant,

To know your Bihar Board Class 10 (Matric) registration number , you can follow these steps:

1. Check your admit card / hall ticket: Your registration number is printed on the admit card issued by your school.

2. School records: Contact your school office or class teacher — they maintain a list of all students with registration numbers.

3. Previous mark-sheets / exam forms: If you have filled the exam form earlier, the registration number is usually mentioned there.

4. Official Bihar School Examination Board (BSEB) website: Some schools can access registration details online through BSEB portal (http://www.biharboardonline.bihar.gov.in) if needed.

Tip: Keep your registration number safe — you will need it for admit cards, result checking, and any official correspondence with the board.

All the best!
