2. Click on the ‘Link Aadhaar’ option under the ‘Quick Links’ section on the left-hand side of the page.
3. Enter your PAN and Aadhaar number, along with your name as per the Aadhaar card.
4. Check the box which says ‘I agree to validate my Aadhaar details with UIDAI’.
5. Enter the captcha code shown on the screen.
6. Click on the ‘Link Aadhaar’ button.
7. If your Aadhaar is already linked to your PAN, a message will be displayed confirming the same.
8. If your Aadhaar is not linked to your PAN, you will be asked to link it by entering your name and date of birth as per the PAN card.

Note: You can also check the status of your PAN-Aadhaar link by sending an SMS to 567678 or 56161 from your registered mobile number. The format of the message should be: UIDPAN <SPACE> 12-digit Aadhaar number <SPACE> 10-digit PAN number.
