Merger Update
If this Ranibari branch was earlier part of Uttar Bihar Gramin Bank (UBGB) or Dakshin Bihar Gramin Bank (DBGB), note the following. UBGB and DBGB have been merged into a single entity under the sponsor bank, Punjab National Bank (PNB). The unified IFSC code for these merged branches is PUNB0MBGB06. Old UBGB or DBGB IFSC codes have been revoked. For electronic transfers (NEFT, RTGS, IMPS) use only the new IFSC PUNB0MBGB06. Transactions attempted with revoked IFSCs will not complete.
What is IFSC Code?
The IFSC is an 11-character alphanumeric code used by Indian banks for electronic fund transfers. Its structure is fixed:
- First 4 characters: bank identifier (for example, PUNB = Punjab National Bank).
- 5th character: reserved and is always 0.
- Last 6 characters: branch identifier. This can be alphanumeric and uniquely points to the branch.
Example: PUNB0MBGB06 — PUNB is the bank, 0 is the reserved digit, and MBGB06 identifies the specific branch in the merged bank network.
How to Use IFSC Code (NEFT, RTGS, IMPS)
- Open your bank’s online or mobile banking app, or visit the branch for paper instructions.
- Choose transfer type: NEFT, RTGS, or IMPS. IMPS is instant and available 24×7. NEFT is commonly available round-the-clock at most banks; settlement timing may vary. RTGS is intended for higher-value transfers (bank limits may apply; many banks treat RTGS for large-value transactions).
- Enter beneficiary name and account number exactly as given by the recipient.
- Enter the IFSC code: PUNB0MBGB06 for Bihar Gramin Bank, Ranibari branch. Make sure there are no typos. IFSC must match the beneficiary branch.
- Enter amount and a transaction remark if needed.
- Verify all details on the confirmation screen before authorizing the transfer with your OTP or transaction password.
- For large or first-time transfers, consider sending a small test amount first to confirm account and IFSC details.
