PAN

PAN obtained once is valid for life-time of the PAN-holder throughout India. It is not affected by change of address or change of Assessing Officer etc. However, any change in the PAN database (i.e. details provided at the time of obtaining PAN) should be intimated to the Income Tax Department by furnishing the details in the form for “Request For New PAN Card Or/ And Changes or Correction in PAN Data”.​​

If a person has been allotted more than one PAN then he should immediately surrender the additional PAN card(s).
