New Delhi: After PAN, around 81 lakh Aadhaar numbers have been deactivated by the UIDAI or Unique Identification Authority of India.

While informing the Rajya Sabha on Friday, Minister of State for Electronics and Information Technology PP Chaudhary told that approximately 81 lakh Aadhaar numbers have been deactivated.

Aadhar is a 12-digit identification number issued to an individual after the receipt of demographic information such as address, date of birth and biometric information such as iris scan, finger prints etc.

Aadhar is slowly becoming the most important document to have. Be it filing your income tax returns, wherein linking Aadhar to PAN card has become mandatory, to obtaining a driving licence, making real estate deals or going ahead with the stock market transaction, you would require Aadhar in all these.

Here’s how you can check the status of your Aadhaar online:

Log on to the UIDAI website - https://uidai.gov.in.

Under the 'Aadhaar Services' tab, click the 'Verify Aadhaar Number’ link

A click on the ‘Verify Aadhaar Number’ tab will take the user to a new page. Now, fill the Aadhaar number and the security code and click 'Verify'.

For active Aadhaar numbers, a message confirming the status of the Aadhaar number will appear. The page also displays basic information such as age band, state and the last three digits of the registered mobile number.

However, in the case of invalid Aadhaar numbers, the page says the number "doesn't exist" at the end of the verification process.
