By now, you might have attempted to link your PAN with Aadhaar. But how to check whether your PAN is already seeded into the Aadhaar system?
Here are some ways to check the status of your Aadhaar-PAN linking:
Online through income tax e-filing website - incometaxindiaefiling.gov.in
Once on the Income Tax Department's e-filing website, find a link called 'Link Aadhaar' and click on it.

On the given form in the next page, proceed by clicking 'Link Aadhaar' after filling in the necessary details, including the PAN number and the Aadhaar number.
For the PANs not registered with the income tax e-filing website, a message on the next page confirms the status of its linking with Aadhaar card. Those individuals who have already registered their PAN with the income tax e-filing website are required to log in.

In such a case, login using your User ID and password.
Select 'Link Aadhaar' under the 'Profile Settings' section.

In case the PAN-Aadhaar linking is already done, a message confirming the same is displayed on the next page.
Through Income Tax Department's SMS facility
The Income Tax Department provides an SMS-based facility to link Aadhaar with PAN.
The user is required to send an SMS to 567678 or 56161 in the following format:
UIDPAN<12-digit Aadhaar><10-digit PAN>
For example: UIDPAN 111122223333 AAAPA9999Q
Comments
For individuals whose Aadhaar is already linked with PAN, the service responds by confirming the same. "Aadhaar...is already associated with PAN...in ITD Database. Thank you for using our services," the SMS reads.Meanwhile, if you have linked your PAN with Aadhaar, you can submit your income tax return online for verification via an Aadhaar OTP (One-Time Password), according to the UIDAI. "You can use Aadhaar based digital signature and complete the process in a few minutes," explains the UIDAI - the issuer of the 12-digit Unique Identity Number as well as Aadhaar card. For such users, there is no need to send their ITR for verification via mail physically.
