The chances of making an error with the IFSC code are less as the page will display the branch details once you enter the IFSC Code, while adding the payee. In spite of that, if you have entered an incorrect IFSC Code, the transfer will match the account number of the recipient and send the money to that account. The chances of a bank having the same account number in two different branches is slim and hence the money will land in the correct account eventually. However, it is imperative that you double check the IFSC Code before initiating the transfer.
