Hy,

here are a few steps you can take:

1. Check Your Email and Admission Portal : Ensure you've checked all communications from the university, including your email and the DU admission portal. Sometimes, roll numbers and other important information are sent via email or updated on the admission portal.

2. Contact the Admission Office : Reach out to the DU admission office or the specific department where you were admitted. They can provide information on your roll number and any other admission-related queries.

3. Visit the University Campus : If possible, visit the campus or the relevant department in person for assistance. Sometimes direct interaction can resolve issues more quickly.
