Merger Update
Important: This IFSC code PUNB0MBGB06 is issued under Punjab National Bank (PNB) for the merged rural bank structure. Uttar Bihar Gramin Bank (UBGB) and Dakshin Bihar Gramin Bank (DBGB) have been consolidated under a single arrangement and now operate using the unified IFSC PUNB0MBGB06. Old UBGB and DBGB IFSC codes have been revoked. For all NEFT/RTGS/IMPS transfers, use only the new IFSC code above. Using an old or revoked IFSC can delay or misroute payments.
What is IFSC Code?
The Indian Financial System Code (IFSC) is an 11-character alphanumeric code used to identify bank branches in electronic fund transfers.
- First 4 characters = bank identifier (example: PUNB = Punjab National Bank).
- 5th character = typically the digit 0 (reserved for future use).
- Last 6 characters = branch identifier (example: MBGB06 points to the specific Sonki/merged branch).
Example: PUNB0MBGB06 breaks down as PUNB | 0 | MBGB06.
How to Use IFSC Code
Follow these steps when sending money (NEFT, RTGS or IMPS):
- Collect the beneficiary details: account name, account number, and IFSC (PUNB0MBGB06).
- Log in to your bank’s internet banking, mobile app, or visit a branch.
- Choose transfer type:
- IMPS for instant small-value transfers (available 24×7).
- NEFT for routine transfers (settlement batches may apply depending on the bank).
- RTGS for large-value, real-time gross settlements (bank may require a minimum amount).
- Add a beneficiary using the beneficiary name, account number and the IFSC exactly as provided. The IFSC is case-insensitive but must match the branch code.
- Verify beneficiary details shown by your bank after addition. A confirmation or OTP step will usually follow.
- Initiate the transfer for the desired amount and keep transaction reference for tracking.
- If the transfer fails or is returned, contact your bank immediately with the reference number.

FAQs
Q: Is PUNB0MBGB06 the only valid IFSC for Sonki branch?
A: Yes. Use PUNB0MBGB06 for all NEFT, RTGS and IMPS transactions. Old UBGB/DBGB IFSC codes are revoked.
Q: What happens if I enter a wrong IFSC?
A: If the IFSC does not match the beneficiary bank and branch, the transfer may fail or be returned. In some cases the bank may route based on account number, but you should not rely on that. Always confirm the IFSC before sending funds.
Q: Can I use the IFSC for UPI transfers?
A: UPI uses a Virtual Payment Address (VPA) and does not require IFSC for payment routing. IFSC is required for bank-to-bank electronic transfers via NEFT/RTGS/IMPS, and when adding beneficiaries in internet banking.
Q: Where can I verify this IFSC before making a transfer?
A: Verify the IFSC on a bank-issued passbook, cheque leaf (if updated), bank branch notice, or confirm with the branch phone number 9297955171. When in doubt, call the branch or the head office toll-free number 18001807777.
Q: How long do NEFT/RTGS/IMPS transfers take?
A: IMPS is typically instant (24×7). NEFT may be settled in hourly or half-hourly batches depending on the bank’s processing; RTGS is usually real-time for high-value transfers. Exact timing can vary by sending bank and cut-off times. Keep the transaction reference to track delays.
