The Bihar Gramin Bank branch at Sontha (Kishanganj district, Bihar) serves local customers for deposits, withdrawals and fund transfers. For electronic transfers—NEFT, RTGS and IMPS—you must use the correct IFSC code so funds reach the intended account without delay. The IFSC links the sending bank and the specific branch in the payment network and is required when setting up beneficiary details in netbanking or mobile apps.

Merger Update
Important: Uttar Bihar Gramin Bank (UBGB) and Dakshin Bihar Gramin Bank (DBGB) have been merged and their operations are now under Punjab National Bank (PNB). All old IFSC codes issued to UBGB/DBGB branches have been revoked. The single, valid IFSC code to use for transactions after the merger is PUNB0MBGB06. If you have older UBGB/DBGB IFSC codes saved, update beneficiary details with the new IFSC before initiating NEFT, RTGS or IMPS transfers to avoid failures or delays.
What is IFSC Code?
The Indian Financial System Code (IFSC) is an 11-character alphanumeric code used to identify bank branches in electronic payment systems. Its structure is:
- First 4 characters: Bank identifier (example: PUNB = Punjab National Bank)
- 5th character: Always 0 (reserved)
- Last 6 characters: Branch identifier (alphanumeric) that pinpoints the specific branch (example: MBGB06 in PUNB0MBGB06).
So PUNB0MBGB06 breaks down as PUNB (bank) + 0 (reserved) + MBGB06 (branch).
How to Use IFSC Code for NEFT, RTGS, IMPS
- Open your bank’s netbanking portal, mobile banking app, or visit an ATM if the bank provides transfer services there.
- Select the transfer type: NEFT for general transfers (batch processed), RTGS for large-value immediate transfers (usually above bank-defined minimum), or IMPS for instant retail transfers available 24×7.
- Choose “Add Beneficiary” or “New Payee”. Enter beneficiary name, account number, and the IFSC code PUNB0MBGB06. Confirm the beneficiary branch details (Sontha, KISHANGANJ).
- After beneficiary is added and activated (some banks require an OTP or cooling period), initiate the transfer and select the beneficiary.
- Confirm amount, purpose and transaction type. Verify IFSC and account number before authorizing the transaction.
- Save transaction or transaction reference for tracking. For NEFT, check batch timings and settlement times; RTGS and IMPS are typically faster, with IMPS available 24×7.
Benefits of Knowing the Correct IFSC

- Reduces failed transactions and associated delays in refunds or reprocessing.
- Makes adding beneficiaries quick and repeatable in netbanking or mobile apps.
- Required for tax and government payments where branch identification is mandatory.

FAQs
-
Q: Can I use PUNB0MBGB06 for all transactions to the Sontha branch?
A: Yes. PUNB0MBGB06 is the valid IFSC for electronic transfers (NEFT, RTGS, IMPS) to the Sontha branch following the UBGB/DBGB merger. Do not use old UBGB or DBGB IFSC codes; they have been revoked.
-
Q: What happens if I enter the wrong IFSC but correct account number?
A: NEFT/RTGS systems typically route by IFSC and account number. If the IFSC points to a different bank or branch, the transfer may fail or be returned. In some cases, banks use account number validation to accept the transfer; still, always use the correct IFSC to avoid delays.
-
Q: Is IFSC case-sensitive?
A: No. IFSC is not case-sensitive. Entering uppercase or lowercase letters does not change the outcome, but use the exact characters for clarity (example: PUNB0MBGB06).
-
Q: How do I confirm if an IFSC is valid?
A: Confirm with the bank branch (phone 9297954404) or check the beneficiary details screen in your bank’s app. After the UBGB/DBGB merger, ensure the IFSC listed is PUNB0MBGB06 for this branch.
-
Q: What are cut-off times for NEFT and RTGS?
A: NEFT operates in hourly or half-hourly batches depending on the bank’s schedule; RTGS is for high-value immediate transfers and typically runs during banking hours with specific cut-offs. IMPS is instant and available 24×7. Check your bank’s schedule before initiating time-sensitive payments.
