An IFSC (Indian Financial System Code) is an 11-character code that is used to identify a specific bank branch that participates in the NEFT (National Electronic Funds Transfer) system in India. The code is used by the Reserve Bank of India (RBI) to ensure that money is transferred to the correct bank branch. It is composed of the bank’s 4-letter code, a zero, and the bank branch’s 6-digit code. The IFSC code can be found on a bank’s checkbook or on the RBI’s website.
