Hi Vejendla Pooja

NTA (National Testing Agency) conducts the JEE Main exam for science stream students who appear or have passed class 12th and want to get admission to undergraduate courses like B.Tech (Bachelor of Technology) or BE (Bachelor of Engineering).

The "Enrollment Number" for the JEE Mains exam refers to the class 11th registration number, which is issued by the school. This number is compulsory for all the students who want to give the JEE Mains exam, and this number is used for verification purposes, such as academic records and cross-checking.

If you do not have this enrollment number, you should contact your school administration to get it, and without this number, you cannot register for the JEE Mains exam 2025-2026.

I hope this information helps you.

Best Wishes.
