how to link pan card with mobile number

You can update the mobile number associated with your PAN card through the official Income Tax e-Filing portal. After logging in, go to the 'My Profile' section to find and edit your 'Contact Details,' where you can enter the new mobile number. An OTP will be sent to this number for verification and confirmation. Alternatively, you can use the 'Changes or Correction in existing PAN Data' service available on the NSDL or UTIITSL authorized portals. This process requires Aadhaar-based verification via OTP to submit the update request for your contact details.
