With so many government welfare schemes linked with Aadhaar, it is one of the most important documents you will ever hold.
Also, a vital proof of identity, it can come handy anywhere and anytime. However, if you don't use it at all, it may get deactivated.
Reasons for which your Aadhaar card might get deactivated
The primary reason your Aadhaar card may get deactivated is non-usage. According to UIDAI officials, if you don't use your Aadhaar for three consecutive years- for example, you don't link it with any service, or don't use it for any transactions, it might get deactivated.
Other reasons for Aadhaar deactivation include mixed or unreliable biometrics, and multiple names under single Aadhaar account.
Case for minors
In case of Aadhaar for children, the condition is that their information such as biometrics must be upgraded once when they attain the age of 5, and again at the age of 15. Failure to do so might also lead to deactivation of Aadhaar.
