If you have xerox copy of your pan or letter of pancard alloted letter then you have to just fill correction form 49B as per sachin alwadhi says and give to nsdl or UTI thats it...simple...dont worry afterthat you will be received your new pancard soon.
first Form 49B is not for obtaining duplicate pan card. Form 49B is Application for allotment of Tax Deduction and Collection Account under section 203A of Income Tax Act 1961.
Just fill the Pan Request Correction form and apply thats all.
