Merger Update for Bihar Gramin Bank
Bihar Gramin Bank is a Regional Rural Bank sponsored by Punjab National Bank. In a move to strengthen and streamline rural banking services, many regional rural banks, including previous entities like Uttar Bihar Gramin Bank (UBGB) and Dakshin Bihar Gramin Bank (DBGB), have undergone mergers. These consolidations have led to the formation of larger entities such as Bihar Gramin Bank, now operating under the sponsorship of Punjab National Bank.
Due to these mergers and restructuring, a unified system for IFSC codes has been put in place. The Mairwa branch of Bihar Gramin Bank now uses the IFSC code PUNB0MBGB06. This code clearly indicates its sponsorship by Punjab National Bank (PUNB) and signifies the branch’s identity within the new structure. It is important to note that any old IFSC codes previously used by banks like UBGB or DBGB for their branches are now revoked and no longer valid for transactions. Always use the current and unified IFSC code, PUNB0MBGB06, for all your fund transfer needs to and from the Mairwa branch.
What is an IFSC Code?
The IFSC (Indian Financial System Code) is an 11-character alpha-numeric code that uniquely identifies every bank branch in India. It’s designed to make electronic fund transfers secure and error-free. Here’s how the code for Bihar Gramin Bank, Mairwa (PUNB0MBGB06) breaks down:
- The first four characters (PUNB) represent the bank. In this case, ‘PUNB’ stands for Punjab National Bank, which is the sponsor bank for Bihar Gramin Bank.
- The fifth character is always ‘0’ (zero). This character is reserved for future use and helps differentiate the bank code from the branch code.
- The last six characters (MBGB06) represent the specific branch. ‘MBGB06’ identifies the Mairwa branch of Bihar Gramin Bank.
How to Use the IFSC Code for Fund Transfers
Using the IFSC code is simple and crucial for various digital payment methods:
For NEFT (National Electronic Funds Transfer):
- Log in to your bank’s online banking portal or mobile app.
