IFSC Code ICIC0005729 — Diamond Heritage, ICICI Bank, Kolkata

Q: What is IFSC code ICIC0005729 and which branch does it identify?

IFSC code ICIC0005729 is the 11-character alphanumeric code assigned by the Reserve Bank of India to the Diamond Heritage branch of ICICI Bank in Kolkata, West Bengal. The first four characters (ICIC) identify the bank across the entire RBI NEFT network, the fifth character is always zero (0), and the last six characters (005729) identify this specific branch. No other branch in India shares this exact 11-character combination. Use ICIC0005729 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 ICIC0005729 to link my ICICI Bank account to UPI?

To link your ICICI Bank Diamond Heritage account to UPI, open any UPI app — PhonePe, Google Pay, Paytm, or BHIM — and select "Add bank account". Choose ICICI 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 ICIC0005729 in the background — you do not need to enter the code manually. Once linked, your UPI VPA (such as yourname@icicibank) 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 ICIC0005729? Is RTGS faster?

NEFT transfers to Diamond Heritage using IFSC ICIC0005729 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 ICIC0005729, which settles within seconds, 24×7, year-round.

Q: How long is the beneficiary cooling period when I add IFSC ICIC0005729 to net banking?

When you add a new beneficiary using IFSC ICIC0005729 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 ICICI Bank Diamond Heritage 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 ICICI Bank's IFSC code changed due to a bank merger? Is ICIC0005729 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 ICICI Bank was involved in a merger, branches of the absorbed bank received new IFSC codes under the surviving bank's code prefix. IFSC ICIC0005729 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 ICIC0005729 have to be zero (0) and not the letter O?

The 5th character of every IFSC code — including ICIC0005729 — 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.

About IFSC Code ICIC0005729 — Diamond Heritage, ICICI Bank

IFSC code ICIC0005729 is the official 11-character alphanumeric identifier assigned by the Reserve Bank of India to the Diamond Heritage branch of ICICI Bank located in Kolkata, West Bengal. This code is used exclusively by India's electronic payment networks — NEFT, RTGS, IMPS, and UPI — to route digital fund transfers to the exact bank branch where the recipient's account is held. IFSC codes are not used for cheque clearing or paper-based instruments; those processes use the MICR code printed on cheque leaves. Without the correct IFSC code, no digital transfer to this branch can be processed.

How to Read IFSC Code ICIC0005729

The 11-character code ICIC0005729 is structured in three segments the RBI uses to route every NEFT and RTGS transfer: ICIC is the bank identifier — a four-letter code that identifies ICICI 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. 005729 is the branch identifier — six alphanumeric characters assigned exclusively to the Diamond Heritage 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.
