That is step 1. That link will only work if you already have linked mobile/email manually at first.
And step 0 is to find a nearby Aadhar Enrollment Center, visit it physically, fight through long queues and palpable rudeness, fill up a form, give your biometrics and then, after wasting almost a full day’s work, hope that the update will be successfully completed in around 20 working days at the least.
Not very “convenient”, esp. with a looming threat that if this doesn’t work, your trading a/c gets suspended, won’t you say?
Needless to say, I’ve already gone through the above strenuous process, because despite everything, I believe in what you say about a citizen’s duty to the Government.
So, your inspired sermon about how to become a model citizen is rather like preaching to the choir, and sadly, bypasses the actual issue.
I do hope your post reflects only your personal opinion, and doesn’t constitute the official stand of Zerodha in this matter.
