What is an IFSC Code?
An IFSC Code is a unique 11-character code assigned by the Reserve Bank of India (RBI) to every bank branch in India. This code helps identify individual branches during online fund transfers.

- The first four characters represent the bank name. For PUNB0MBGB06, “PUNB” stands for Punjab National Bank, which is the sponsor bank for Bihar Gramin Bank.
- The fifth character is always a zero (0). This character is kept as a control measure for future use.
