Merger Update for Bihar Gramin Bank
Bihar Gramin Bank was formed as a result of a significant merger. Both Uttar Bihar Gramin Bank (UBGB) and Dakshin Bihar Gramin Bank (DBGB) have now merged to form a single entity, Bihar Gramin Bank. As part of this consolidation, the bank now operates under the sponsorship of Punjab National Bank (PNB). This means that all branches, including the Main Branch / Laheriasarai, use a unified IFSC code structure beginning with “PUNB”.
For any transactions involving Bihar Gramin Bank, including the Main Branch / Laheriasarai, the only valid IFSC code to use is PUNB0MBGB06. It is crucial to remember that any old IFSC codes previously associated with Uttar Bihar Gramin Bank or Dakshin Bihar Gramin Bank branches are now revoked and will not work for transactions. Always use the new and active code to avoid any transfer failures or delays.
What is an IFSC Code?
The IFSC (Indian Financial System Code) is an 11-character alphanumeric code used to identify all bank branches across India participating in online fund transfers. It’s unique to each branch, ensuring that your money goes exactly where you intend it to go.
Let’s break down the IFSC code PUNB0MBGB06:
- The first four characters, PUNB, represent the sponsor bank, which in this case is Punjab National Bank.
- The fifth character is always 0 (zero). This character is reserved for future use and acts as a control digit.
- The last six characters, MBGB06, specifically identify the individual branch. For this particular code, “MBGB” refers to the Main Branch of Bihar Gramin Bank, and “06” is a unique identifier for the Laheriasarai branch within that structure.
This systematic structure helps in accurately routing funds through the interbank payment system.
How to Use an IFSC Code
You will need the IFSC code whenever you perform an online fund transfer. Here’s how you typically use it for NEFT, RTGS, or IMPS:
- Log in to Net Banking or Mobile Banking: Access your bank’s online platform using your credentials.
- Select Funds Transfer: Choose the option for transferring funds. This might be labeled “NEFT,” “RTGS,” “IMPS,” or simply “Transfer Funds.”
- Add Beneficiary: If you’re sending money to someone for the first time, you’ll need to add them as a beneficiary. Provide the recipient’s name, their account number, the bank name (Bihar Gramin Bank), and the correct IFSC code (PUNB0MBGB06).
- Verify Details: Double-check all the information you’ve entered, especially the account number and IFSC code, to prevent errors.
- Enter Amount and Confirm: Specify the amount you wish to transfer and confirm the transaction. You might receive an OTP (One-Time Password) to complete the process.
For recurring transfers to an existing beneficiary, you will simply select their name, enter the amount, and proceed, as their bank and IFSC details are already saved.
Benefits of Knowing the IFSC Code
Knowing the correct IFSC code for a bank branch offers several key advantages:
- Accurate Fund Transfers: It ensures your money reaches the intended beneficiary’s account in the correct bank and branch, minimizing the risk of misdirected funds.
- Faster Processing: Correct IFSC codes help banks process NEFT, RTGS, and IMPS transactions quickly and efficiently.
- Unique Branch Identification: Each branch has a distinct IFSC, eliminating confusion even if multiple branches share similar names or are in the same city.
- Prevents Errors: Using the right code helps avoid transaction failures, which can cause delays and inconvenience.
- Essential for Online Transactions: It is a mandatory detail for all major electronic fund transfer methods, making online banking seamless.
