Changing a bank account on Groww is easy and quick. When you withdraw money from Groww Balance, the withdrawn money is credited to your primary bank account. If you have registered more than one account with Groww, you can choose the bank that you want to make primary (to which you want to withdraw the money) on the bank details page.
Here is how you can change your primary bank account:
1. Go to your Groww profile and click on "Bank Details"
2. Select the bank account and click on "Make Primary"
3. Read the confirmation message and click on "Make Primary" again
Congratulations! You've changed your primary bank account successfully.
