How to change your Zerodha user ID

No, you cannot change your Zerodha user ID. Zerodha’s own help desk states it plainly: you cannot change or customise your user ID, because it is registered on the exchange to track all your transactions, which makes it permanent and unchangeable. The 12-character user ID , the code such as AB1234 that identifies your account, is not an editable profile field like your email or mobile. It is an exchange-level identifier tied to every trade you have placed. This guide explains why it is fixed, what you can change instead, and how to recover a forgotten ID, which is the real need behind most searches to “change” one.
