How to convert a secondary bank account to primary on Zerodha

A Zerodha trading account can hold a maximum of three bank accounts: one primary account and up to two secondary accounts. Converting a secondary account into the primary account is a different task from adding a new bank or changing to a bank you have never linked. Here both accounts already sit on your profile, and you are only asking Zerodha to swap which one carries the primary role. This guide covers the conversion through Zerodha Console , the Aadhaar e-sign that authorises it, the Rs 25 plus 18% GST charge, and the 72 working hour processing window.
