how to update pan card mobile number

The mobile number associated with your PAN card can be updated using the following methods:

• For updating the mobile number linked to your e-Filing account, log in to the official Income Tax portal, navigate to 'My Profile,' and edit your 'Contact Details,' followed by OTP verification.
• To formally change the mobile number in the permanent PAN database, submit the 'Changes or Correction in PAN Data' application on either the Protean (formerly NSDL) or UTIITSL online portals.
• This correction process is typically completed through an Aadhaar-based e-KYC verification.
