Log on to www.incometax.gov.in/iec/foportal/ and click on 'Verify your PAN' which is on the left column under the 'Quick Links' section.
As soon as you click on the Verify your PAN' tab, you'll be redirected to a page where you are required to fill in some details.
These details include PAN number, name, date of birth and contact number.
Next, you’ll be redirected to another page where you will have to put the OTP sent on your registered mobile number.
Make sure your mobile number is linked to PAN.
Enter the OTP received and click on 'Validate'.
If your PAN card details haven't been duplicated or issued to multiple people, the last page will show 'PAN is Active and details are as per PAN'.
If you have more than one PAN card registered under the same personal details, a message will appear saying, "There are multiple records for this query. Provide additional information."
In this case, you'll have to provide your father's name and other identification details.
