You can correct your address in your PAN card online through the official portals of Protean (formerly NSDL e-Gov) or UTIITSL.
The general process involves:
- Visiting the respective portal and selecting 'Change/Correction in PAN Data/Reprint of PAN Card'.
- Filling the online form and selecting the address field for correction.
- Submitting the required documents, such as proof of address.
You can opt for the paperless Aadhaar-based e-KYC process for an easier update, which will fetch the address directly from your Aadhaar.
