How can the Aadhaar number be unlinked from the Zerodha account?

All Aadhaar numbers collected as part of the Prevention of Money Laundering (PMLA) under the exchange guidelines were removed after the supreme court judgement on September 27, 2018.

Aadhaar details like address, DOB and gender are used only if the Aadhaar is used as identity and address proof while opening an account.
