Indian Overseas Bank IFSC code

Use the bank’s current locator or other current bank-issued details. Most suffixes are numeric, while legacy rural-bank and service records use letters.

1. 1

   Check current bank-issued details

   Confirm the full eleven-character code supplied for the beneficiary’s account.

2. 2

   Ask the beneficiary to verify it

   Do not substitute the code of a nearby branch or reuse an old payment instruction.

3. 3

   Use the bank’s own locator

   IOB’s branch and ATM finder searches by state, city and locality, and prints the IFSC on each result.

4. 4

   Search the branch table below

   Every code indexed here has a page with the branch address and, where known, the MICR.

The Reserve Bank defines the shape: eleven characters, the first four identifying the bank, the fifth always the digit zero, and the last six identifying the branch.

IOBA

Bank code — identical on every branch

0

Always the digit zero, never the letter O

000058

Branch — Mount Road, Anna Salai, Chennai

Of the 4,714 records indexed here, 3,706 end in six digits: IOBA0000058 is Mount Road and IOBA0000048 is Esplanade. Another 1,001 start IOBA0GB and are legacy Odisha rural-bank records. The remaining seven alphanumeric records are labelled for cards, UPI, an Odisha rural-bank IMPS endpoint or digital banking.

These are legacy records. The snapshot contains 1,001 IOBA0GB codes for former Odisha Gramya Bank branches. That bank and Utkal Grameen Bank were amalgamated into Odisha Grameen Bank on 1 May 2025 under Indian Overseas Bank sponsorship.

Do not assume an IOBA0GB code is current. Odisha Grameen Bank announced that individual IFSCs for former Odisha Gramya Bank branches would take effect on 30 August 2025. Ask the beneficiary for the current code or verify it on the current bank site before sending.

For an account-number-and-IFSC transfer, use the beneficiary’s current branch code. NEFT runs round the clock in half-hourly batches with no RBI minimum; RTGS also runs round the clock but starts at ₹2,00,000, with no ceiling.

Online NEFT from a savings account is free, as the RBI has required of every bank since 1 January 2020, while doing the same transfer at the counter costs money. Charges change: those figures are IOB’s schedule as published April 2026, before GST.

An IFSC does nothing here — it is a domestic routing code. IOB’s inward remittance page is blunt about what a foreign sender needs: the “Full 15 digit bank account number”, the “Beneficiary name as per bank records”, and “For Personal remittances always use our swift code IOBAINBB001”.

• IOB’s published wire template asks for the account number, account name and beneficiary branch; no IFSC field appears. Follow the receiving bank’s current instructions.
• The correspondent in field 56 is currency-specific: Citibank for US dollars, others for GBP, EUR, AUD, CAD, JPY and SGD.

IOB publishes overseas SWIFT centres in Singapore, Hong Kong, Bangkok and Colombo, each with its own BIC. Those are separate from the IOBAINBB001 instruction for a personal inward remittance to India.

RBI rules require a destination bank to return an uncreditable NEFT “within two hours of completion of the batch in which the transaction was processed”. If a bank neither credits nor returns within the required window, the RBI FAQ provides for penal interest without waiting for a claim.

1. 01Read the prefix back: IOBA0, four letters then the digit zero. IOB0 and IOBA0O are the two ways this goes wrong.
2. 02Compare all six branch digits against the beneficiary’s chequebook or app. There is no word in the code to sanity-check them against.
3. 03Check the account number for leading zeros a spreadsheet dropped. The RBI says credit “is released solely based on account number”, so the right name will not rescue a wrong number.
4. 04Nothing credited and nothing returned after two hours: quote the transaction reference to your own bank, not to IOB.
