Hello

Yes, you can use your old Aadhaar card for scholarships as long as your name, address, and other details are correct and match your documents.
The main thing is that the information on your Aadhaar should be clear and up to date.
If nothing has changed, there’s no need to update or reissue it.
Scholarship portals usually verify Aadhaar through an online UIDAI link, so make sure it’s active.
If your card is damaged or hard to read, you can download a fresh digital copy from uidai.gov.in .
So yes, your old Aadhaar is completely valid for applying to scholarships
