Important Merger Update
Bihar Gramin Bank was formed by the amalgamation of two regional rural banks: Uttar Bihar Gramin Bank (UBGB) and Dakshin Bihar Gramin Bank (DBGB). As a result of this merger, the banking operations are now sponsored by Punjab National Bank (PNB).
A significant change is that all branches of the newly formed Bihar Gramin Bank, including the Koilwan branch, now use a unified IFSC code for all online transactions. The correct and valid IFSC code is PUNB0MBGB06. Any old IFSC codes belonging to the former Dakshin Bihar Gramin Bank or Uttar Bihar Gramin Bank are now invalid and have been revoked. Using an old code will result in failed transactions, so it is crucial to update your records and use only the new code.
What is an IFSC Code?
The IFSC is an 11-character alphanumeric code assigned by the Reserve Bank of India (RBI) to identify every bank branch participating in online fund transfer systems. The code has a specific structure that helps route transactions correctly.
Let’s break down the IFSC code for this branch, PUNB0MBGB06:
- PUNB: The first four letters represent the bank’s name. In this case, it is ‘PUNB’ for Punjab National Bank, the sponsor bank.
- 0: The fifth character is always a zero. It is reserved for future use.
- MBGB06: The last six characters identify the specific branch. For the merged Bihar Gramin Bank, ‘MBGB06’ serves as a unified identifier.
How to Use the IFSC Code for Fund Transfers
Using the IFSC code to transfer money is straightforward. Whether you are using your bank’s mobile app or internet banking portal for NEFT, RTGS, or IMPS, the steps are generally the same.
1. Log in to your net banking or mobile banking application.
2. Navigate to the ‘Fund Transfer’ section and choose to ‘Add a Beneficiary’ or ‘Payee’.
3. Enter the beneficiary’s details: This includes their full name, bank account number, and the bank name (Bihar Gramin Bank).
4. Enter the IFSC Code: In the designated field, carefully type PUNB0MBGB06. Double-check for accuracy, as a wrong code is a common reason for transaction failure.
5. Confirm the details and add the beneficiary. Once added, you can select them from your list of payees and initiate the transfer by entering the amount.
Benefits of Using the Correct IFSC
- Ensures Accuracy: The code directs your money to the exact bank and branch, eliminating guesswork and reducing the risk of funds going to the wrong place.
- Prevents Delays: A correct IFSC code allows for automated, straight-through processing, which means your transfer is completed quickly without manual intervention.
- Enables Digital Payments: It is the backbone of India’s major electronic payment systems, including NEFT, RTGS, and IMPS, making digital transactions possible.
- Avoids Transaction Failures: Using the updated, correct code prevents transfers from being rejected or reversed, saving you time and potential fees.
