Protect your Aadhaar data: Here's how to lock/unlock Aadhaar number
What's the story
In a bid to strengthen the privacy and security of Aadhaar, the Unique Identification Authority of India (UIDAI) has introduced a feature that enables users to lock/unlock their Aadhaar number.
Once locked, your Aadhaar number cannot be used for authentication purpose.
To facilitate authentication, you will have to generate your 16-digit Aadhaar Virtual ID.
Here's how you can lock/unlock your Aadhaar number.

Interchangeability
Separately, Aadhaar and PAN are now interchangeable
On a related note, you can now quote your Aadhaar number in place of PAN to file your I-T returns.
This comes after Union Finance Minister Nirmala Sitharaman in her budget speech announced that Aadhaar and PAN can now be used interchangeably.
Further, Aadhaar can also be used for services where quoting PAN is necessary such as buying gold, MF etc.
Aadhaar status
Clearing the air around Aadhaar status
Post the September 26, 2018 Supreme Court verdict relating to authentication of Aadhaar, there has been much confusion with respect to services where Aadhaar is necessary and where not.
Aadhaar is no longer mandatory for services such as bank account, telecom services, and school admissions/entrance tests.
However, it is still necessary for getting a PAN, and availing various government welfare schemes.
