how to add surname in pan card

To add or correct your surname on your PAN card, apply for a 'Changes or Correction in existing PAN Data' through the official Protean (formerly NSDL e-Gov) or UTIITSL portal. When filling the online form, select the relevant checkbox next to the 'Last Name / Surname' field. You must submit valid documentary proof supporting the surname change, such as a marriage certificate or a gazette notification, and pay the applicable fee to process your request.
