IFSC or Indian Financial System Code is a special code given to every bank branch in India. It is a 11 digit code with the first 4 characters being the abbreviation of the Bank followed by a control character in the fifth place and then the branch code will represent the last 6 characters.
For example, the IFC code of SBI Main branch in Kolkata is given the code SBIN0000001.
This IFSC code may be required at times when you are to receive payments from outside India, like in the case of Paypal depositing funds in your bank account.
To find the IFSC code of any bank branch in India, visit this page on the RBI website and click on List of NEFT enabled bank branches (Bank wise). Select your bank and then find your branch’s IFSC code. Be sure that you are only seeing at IFSC code and not the MICR code.
