how to change number in pan card

To change the mobile number linked to your PAN card, you must submit an update request through an authorized portal.

• The quickest method is via the Income Tax e-Filing portal: Log in to your account, navigate to the 'My Profile' section, select 'Profile Settings', and edit your contact details by providing the new mobile number and confirming with an OTP.
• Alternatively, you can apply for a 'Change/Correction in PAN Data' on the Protean (formerly NSDL e-Gov) or UTIITSL website. Fill out the correction form, tick the relevant box for updating contact details, enter your new mobile number, and submit the application, typically using an Aadhaar-based e-KYC process.
