how to change phone number on pan card

To change your phone number on your PAN card, you have two primary options:

• For updating your tax profile, log in to the official Income Tax e-Filing website. Go to 'My Profile' and 'Profile Settings', edit your contact details, enter the new mobile number, and verify with the OTP.
• For a formal correction on the PAN database, use the 'Changes or Correction in existing PAN Data' form on the NSDL (Protean) or UTIITSL portal. Enter the new number, complete the Aadhaar e-KYC/e-Sign verification, and submit after paying the applicable fee.
