IFSC Code IOBA0000271 — Uchipulli, Indian Overseas Bank,

Q: What is IFSC code IOBA0000271 and which branch does it identify?

IFSC code IOBA0000271 is the 11-character alphanumeric code assigned by the Reserve Bank of India to the Uchipulli branch of Indian Overseas Bank in Ramanathapuram, Tamil Nadu. The first four characters (IOBA) identify the bank across the entire RBI NEFT network, the fifth character is always zero (0), and the last six characters (000271) identify this specific branch. No other branch in India shares this exact 11-character combination. Use IOBA0000271 for NEFT, RTGS, IMPS transfers and to link this account to UPI apps like PhonePe, Google Pay, and BHIM.

Q: How do I use IFSC IOBA0000271 to link my Indian Overseas Bank account to UPI?

To link your Indian Overseas Bank Uchipulli account to UPI, open any UPI app — PhonePe, Google Pay, Paytm, or BHIM — and select "Add bank account". Choose Indian Overseas Bank from the bank list. The app will auto-detect your registered mobile number and retrieve your account. During verification, the app validates your account against IFSC IOBA0000271 in the background — you do not need to enter the code manually. Once linked, your UPI VPA (such as yourname@indianoverseasbank) is used for daily payments. The IFSC is only needed during this initial account registration step, not for individual UPI transactions.

Q: What is the NEFT settlement time using IFSC IOBA0000271? Is RTGS faster?

NEFT transfers to Uchipulli using IFSC IOBA0000271 settle in half-hourly batches — available 24 hours a day, 7 days a week including public holidays. A transfer sent at 2:10 PM is batched at 2:30 PM and credited shortly after. There is no minimum or maximum amount for NEFT. RTGS is faster but has a ₹2 lakh minimum. RTGS settles in real time during RBI operating hours (7:00 AM to 6:00 PM on working days). For transfers below ₹2 lakh that need to arrive instantly — including on weekends and bank holidays — use IMPS with IFSC IOBA0000271, which settles within seconds, 24×7, year-round.

Q: How long is the beneficiary cooling period when I add IFSC IOBA0000271 to net banking?

When you add a new beneficiary using IFSC IOBA0000271 in net banking or mobile banking, most banks enforce a cooling period of 30 minutes to 24 hours before the first transfer is permitted. During this window, the bank sends a confirmation OTP or push notification and blocks outgoing transfers to the new beneficiary. This is a fraud-prevention measure. After the cooling period, per-transaction and per-day limits apply based on your bank's policy and your account type. If you need to transfer money urgently to a Indian Overseas Bank Uchipulli account, add the beneficiary at least one business day in advance. UPI payments bypass beneficiary cooling periods entirely — they can be initiated to a new UPI ID without any wait.

Q: Has Indian Overseas Bank's IFSC code changed due to a bank merger? Is IOBA0000271 still active?

Bank mergers in India can deactivate IFSC codes. When the RBI merges two banks, it typically issues new IFSC codes for the surviving entity's branches and deactivates old codes from the absorbed bank — sometimes immediately, sometimes on a scheduled date. If Indian Overseas Bank was involved in a merger, branches of the absorbed bank received new IFSC codes under the surviving bank's code prefix. IFSC IOBA0000271 is listed as active in our database as of Jun 2026. However, before initiating a large RTGS or NEFT transfer, we recommend verifying on the RBI's official IFSC lookup to confirm the code remains valid.

Q: Why does the 5th character of IFSC IOBA0000271 have to be zero (0) and not the letter O?

The 5th character of every IFSC code — including IOBA0000271 — is always the digit zero (0), not the letter O. The RBI mandated this design: position 5 is permanently reserved for future use and is always set to the numeral 0. In many printed fonts and small screens, the digit 0 and the letter O look nearly identical, but they are entirely different ASCII characters. If you type the letter O instead of 0, the payment system will reject the transfer immediately with an "invalid IFSC" error — no transfer will be processed and no money will leave your account. If a transfer to this branch fails IFSC validation, check position 5 of the code first: it must be the digit 0.

How to Read IFSC Code IOBA0000271

The 11-character code IOBA0000271 is structured in three segments the RBI uses to route every NEFT and RTGS transfer: IOBA is the bank identifier — a four-letter code that identifies Indian Overseas Bank in the RBI's settlement network. 0 is the reserved zero at position 5 — always the digit 0 (never the letter O), mandated by the RBI for future use. 000271 is the branch identifier — six alphanumeric characters assigned exclusively to the Uchipulli branch. No other branch in India carries this exact combination, which is what allows NEFT and RTGS systems to credit funds to one specific branch out of more than 1.6 lakh branches nationwide.
