If you live in India, then there is a lot of hype and pressure to get various policies and documents linked to you Aadhar number. Here is a small list I found on how to go about it.


The following banks allow you to login to your Internet Banking account and link you Aadhar number.




Standard Chartered Bank

Corporation Bank

Axis Bank


Shares and Mutual Funds

Your demat trading account will have a provision when you login to link Aadhar number. However this doesn’t apply for Mutual Funds. All mutual funds go through Karvy or CAMS, hence you can visit the following links to update your Aadhar.

Insurance Policies

MAX Life
Exide Life
Bajaj Allianz


ICICI Lombard
