Unfortunately, you cannot add funds to your Upstox account via NEFT or an external UPI of an unregistered bank. If you have added funds from an unregistered bank, we will not be able to credit the funds and your payment will be kept on hold.

In such a situation, the amount will be refunded to the same bank account.

1. Kindly provide the bank details such as your beneficiary name, account number, and IFSC code so that we can process the refund back into your unregistered bank account.

2. To add the transferred funds to your trading account you need to link this bank to your Upstox account. 

please refer to the link below on how to add a bank in Upstox.
