Important Merger Update
Bihar Gramin Bank was formed by merging two regional rural banks: Uttar Bihar Gramin Bank (UBGB) and Dakshin Bihar Gramin Bank (DBGB). After the merger, the bank is sponsored by Punjab National Bank (PNB). As a result, all branches, including Nathnagar, now use a new, unified IFSC code structure that starts with ‘PUNB’. The official and only valid IFSC code for this branch is PUNB0MBGB06. Any old IFSC codes associated with the former UBGB or DBGB are no longer active and will cause transactions to fail. Always use the new code for all fund transfers.
What is an IFSC Code?
The Indian Financial System Code (IFSC) is a unique 11-character alphanumeric code assigned by the Reserve Bank of India (RBI) to every bank branch participating in the electronic funds transfer network. It ensures that money is sent to the correct bank and branch.
The structure of the Nathnagar branch IFSC code, PUNB0MBGB06, can be broken down as follows:
- PUNB: The first four alphabetic characters represent the bank’s name. In this case, it is for Punjab National Bank, the sponsor bank.
- 0: The fifth character is always a zero. It is a control character reserved for future use.
- MBGB06: The last six characters identify the specific branch. For Nathnagar, this is ‘MBGB06’.
How to Use the IFSC Code for Fund Transfers
Using the IFSC code for online banking is straightforward. Whether you are using a mobile banking app or a web portal, the steps are generally the same.
- Log in to your internet banking or mobile banking account.
- Navigate to the ‘Fund Transfer’ or ‘Payments’ section and select the transfer type (NEFT, RTGS, or IMPS).
- Choose the ‘Add Beneficiary’ or ‘Add Payee’ option to add the recipient’s account details.
- Enter the beneficiary’s name, account number, and the bank’s IFSC code: PUNB0MBGB06.
- After the beneficiary is successfully added, you can initiate the fund transfer by entering the amount and confirming the transaction.
Benefits of Using the Correct IFSC Code
- Transaction Accuracy: The primary benefit is ensuring your money reaches the intended recipient’s branch and account without any errors.
- Faster Processing: Correct codes enable automated systems to process transactions quickly, minimizing delays.
- Reduced Risk of Failure: Using the right IFSC code prevents transaction rejections that occur when an incorrect or outdated code is entered.
- Security: It adds a layer of verification to the fund transfer process, confirming that the account number is linked to the correct bank branch.

Frequently Asked Questions (FAQs)
1. Can I still use my old Dakshin Bihar Gramin Bank (DBGB) IFSC code?
No. After the merger, all old IFSC codes from DBGB and UBGB have been deactivated. You must use the new IFSC code, PUNB0MBGB06, for all transactions to the Nathnagar branch.
2. Why does the Bihar Gramin Bank IFSC code start with ‘PUNB’?
The code starts with ‘PUNB’ because Punjab National Bank (PNB) is the sponsor bank for Bihar Gramin Bank. The IFSC code format reflects the sponsor bank’s identity.
3. What happens if I enter the wrong IFSC code?
If you enter an incorrect IFSC code, the transaction will likely be rejected, and the funds will be returned to your account. In some rare cases, if the code corresponds to another branch, the transfer could be misdirected, leading to delays in recovery.
4. Are IFSC and MICR codes the same thing?
No. The IFSC code is used for online fund transfers like NEFT and RTGS. The Magnetic Ink Character Recognition (MICR) code is a 9-digit code found at the bottom of a cheque leaf, used for processing physical cheques.
5. Is the IFSC code the same for all Bihar Gramin Bank branches?
No. While the first four characters (‘PUNB’) are common for all branches due to the sponsor bank, the last six characters are unique to each specific branch. For example, the code for Nathnagar is PUNB0MBGB06, but another branch will have a different six-character identifier.
