A code uniquely identifies each bank branch participating in the three main Payment and settlement systems in India: the National Electronic Funds Transfer (NEFT), Real Time Gross Settlement (RTGS) and Immediate Payment Service (IMPS) systems.
[1] The IFSC is an 11-character code with the first four alphabetic characters representing the bank name, and the last six characters (usually numeric, but can be alphabetic) representing the branch.
Bank IFS Code is used by the NEFT & RTGS systems to route the messages to the destination banks/branches.
Bank-wise lists of IFS Codes are available with all the bank-branches participating in inter bank electronic funds transfer.
A list of bank-branches participating in NEFT/RTGS and their IFS Code is available on the website of the Reserve Bank of India.
