Hi Mahi,
No need to worry about that. With the same PAN number, you can apply for another one. I think it will cost Rs. 97. You can go to any UTI TSL center, apply for a new one (Fill CSF form), along with your ID proof and Address proof. If you have any queries, please visit the UTITSL India: Financial & IT Service Provider, PAN Card Issuer website at [url=http://www.utitsl.co.in].

Ravi Kandi.
