Last updated: October 9, 2026 · By Govind Kumar · Checked against Bihar Gramin Bank, RBI and merger information available as of this update
Picture a father in Muzaffarpur filling a scholarship form for his daughter. The portal keeps rejecting the account number, so he counts the digits on her passbook: 16. His cousin in Gaya, whose account was opened with the old Dakshin Bihar Gramin Bank, has a number that looks quite different. Both can be correct. If you are confused about Bihar Gramin Bank account number digits, this Wikipedia Search guide explains why lengths can differ, how to find your real number in 30 seconds, and the small mistakes that cause most rejected forms.
The 30-Second Check: Count Your Account Number the Right Way
Before anything else, confirm what is actually on your passbook. Most “wrong digit” problems come from reading the wrong field.
- Open the first page of your passbook (the page with your photo and name).
- Find the line labelled “Account No.” or “A/c No.” Ignore lines labelled CIF, Customer ID or IFSC.
- Count every digit, including any zeros at the start. Write it in groups of four to avoid miscounting, for example 1234 5678 9012 3456.
- Match it with an SMS or statement. A transaction SMS usually shows only the last few digits, which helps confirm you have the right number.
- Still unsure? Ask your branch to print your account number on a fresh passbook entry.
That count is your answer. No website, including this one, can override what your bank has printed.
Account Number vs CIF vs IFSC: Which Number Is Which?
Your passbook carries several numbers that look similar. Mixing them up is the single most common reason people think their Bihar Gramin Bank account number has the “wrong” number of digits.
| Field on passbook | What it identifies | Typical format |
| Account number | Your specific savings or current account | Digits only; former UBGB accounts are widely reported as 16 digits |
| CIF / Customer ID | You as a customer (one CIF can hold several accounts) | Digits only, usually shorter than the account number |
| IFSC code | The bank branch for NEFT, RTGS and IMPS | Always 11 characters: 4 letters, a zero, then 6 letters or digits |
| MICR code | The branch for cheque clearing | Always 9 digits |
Quick rule: if the number contains letters, it is not your account number. If it is 9 digits, it is almost certainly the MICR code.
Why Old UBGB and DBGB Accounts Can Look Different
Here is the part most guides skip. Bihar Gramin Bank did not start from scratch. It was created on 1 May 2025 by combining two separate banks:
| Former bank | Area | Earlier sponsor | Account number length |
| Uttar Bihar Gramin Bank (UBGB) | North Bihar | Central Bank of India | Widely reported as 16 digits |
| Dakshin Bihar Gramin Bank (DBGB) | South Bihar | Punjab National Bank | No single officially published figure |
The two banks ran on different core banking systems for years, each with its own numbering pattern. After the merger, customers were told their account number stays the same. So today, one bank can hold account numbers of more than one length, depending on where each account was originally opened.
That is why we do not claim one universal digit count for every Bihar Gramin Bank account. A site that gives you a single number for all customers is guessing about at least some of them.
If your account was opened with the old Uttar Bihar Gramin Bank, this detailed guide on Uttar Bihar Gramin Bank account number digits breaks down the 16-digit format further.
What Changed After the Merger (and What Did Not)
| Item | Status after 1 May 2025 |
| Account number | Unchanged for existing customers |
| Bank name | Now Bihar Gramin Bank on all new documents |
| Sponsor bank | Punjab National Bank |
| IFSC code | Many former UBGB branches moved from CBIN-prefixed codes to PUNB-prefixed codes; confirm yours before any transfer |
| Passbook, ATM card, balance | Continue to work; the branch may replace them during system migration |
| Official website | bgb.bank.in |
Watch out for wrong IFSC codes online. Some websites list the old UBGB code as “CBIN0R1001,” which has only 10 characters. A valid IFSC always has 11. Others claim both banks now run as “Madhya Bihar Gramin Bank,” which is not true. Before saving a beneficiary, verify the IFSC on the RBI’s official IFSC search or ask your branch.
5 Mistakes That Get Your Account Number Rejected
These come up again and again on scholarship portals, PM-Kisan forms, salary sheets and UPI apps.
1. Typing the CIF instead of the account number. The CIF is shorter and sits close to the account number on the passbook. Double check the label.
2. Dropping zeros at the start. If your account number begins with 0, some forms and Excel sheets silently remove it. Type it as text, or add an apostrophe before the number in Excel.
3. Adding spaces or dashes. Write the number in groups of four only on paper. On forms, enter all digits together unless the field asks otherwise.
4. Using an old IFSC with a correct account number. The account number may be right, but a pre-merger IFSC can still make the transfer fail. Always pair your number with the current IFSC.
5. Copying from a blurry photo. A 6 can look like an 8 and a 1 like a 7 on a phone photo. Read directly from the passbook or the bank’s SMS.
Where to Find Your Bihar Gramin Bank Account Number
| Source | Where to look |
| Passbook | First page, line marked “Account No.” |
| Cheque leaf | Printed at the top, above the MICR band |
| Account opening slip or welcome kit | Given at the time of opening |
| Bank statement | Top section with your name and address |
| Branch visit | Carry your Aadhaar or any photo ID, and staff can confirm it |
Safety tip: never share your full account number together with an OTP, ATM PIN or UPI PIN with anyone on a call, even if they claim to be from Bihar Gramin Bank. Bank staff will never ask for your PIN or OTP.
FAQs
How many digits are in a Bihar Gramin Bank account number?
It depends on where your account was first opened. Former Uttar Bihar Gramin Bank accounts are widely reported as 16 digits, while former Dakshin Bihar Gramin Bank accounts may follow a different length. Your passbook shows the exact count for your account.
Did my account number change after Uttar Bihar Gramin Bank became Bihar Gramin Bank?
No. Existing customers kept their account numbers after the 1 May 2025 merger. The bank name changed, and many branches received new IFSC codes, so update the IFSC wherever you have saved your details.
Is the CIF number the same as the account number?
No. The CIF, or customer ID, identifies you as a customer and is usually shorter. The account number identifies one specific account. Forms for transfers, subsidies and salary always need the account number.
Why is my Bihar Gramin Bank account number not accepted on a form?
The most common reasons are a missing zero at the start, typing the CIF by mistake, extra spaces, or an outdated IFSC entered alongside it. Check each one before contacting the branch.
Bihar Gramin Bank account number mein kitne digit hote hain?
Ye is baat par depend karta hai ki account kis bank mein khula tha. Purane Uttar Bihar Gramin Bank ke account number aam taur par 16 digit ke bataye jaate hain. Sabse sahi jawab aapki passbook ke pehle page par likha “Account No.” hai.
Merger ke baad kya naya account number milega?
Nahi. Uttar Bihar aur Dakshin Bihar Gramin Bank milkar Bihar Gramin Bank bane, lekin purana account number wahi rehta hai. Bas IFSC code badal sakta hai, isliye UPI ya transfer mein naya IFSC zaroor update kariye.

You now know how to read your passbook correctly, why account numbers can differ in length within the same bank, and the five mistakes that cause most rejections.
