This is an 11-character code with the first four alphabetic characters representing the bank, and the last seven characters (usually numeric, but can be alphabetic) representing the branch. The fifth character is 0 (zero). IFSC is used by the NEFT & RTGS systems to route the messages to the destination banks/branches.
