What is IFSC code UTKS0001924 and which branch does it identify?

IFSC code UTKS0001924 is the 11-character alphanumeric code assigned by the Reserve Bank of India to the Islamnagar branch of Utkarsh Small Finance Bank in Au, Bihar. The first four characters (UTKS) identify the bank across the entire RBI NEFT network, the fifth character is always zero (0), and the last six characters (001924) identify this specific branch. No other branch in India shares this exact 11-character combination. Use UTKS0001924 for NEFT, RTGS, IMPS transfers and to link this account to UPI apps like PhonePe, Google Pay, and BHIM.

How do I use IFSC UTKS0001924 to link my Utkarsh Small Finance Bank account to UPI?

To link your Utkarsh Small Finance Bank Islamnagar account to UPI, open any UPI app — PhonePe, Google Pay, Paytm, or BHIM — and select "Add bank account". Choose Utkarsh Small Finance 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 UTKS0001924 in the background — you do not need to enter the code manually. Once linked, your UPI VPA (such as yourname@utkarshsmallfinancebank) is used for daily payments. The IFSC is only needed during this initial account registration step, not for individual UPI transactions.

What is the NEFT settlement time using IFSC UTKS0001924? Is RTGS faster?

NEFT transfers to Islamnagar using IFSC UTKS0001924 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 UTKS0001924, which settles within seconds, 24×7, year-round.

How long is the beneficiary cooling period when I add IFSC UTKS0001924 to net banking?

When you add a new beneficiary using IFSC UTKS0001924 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 Utkarsh Small Finance Bank Islamnagar 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.

Has Utkarsh Small Finance Bank's IFSC code changed due to a bank merger? Is UTKS0001924 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 Utkarsh Small Finance Bank was involved in a merger, branches of the absorbed bank received new IFSC codes under the surviving bank's code prefix. IFSC UTKS0001924 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.

Why does the 5th character of IFSC UTKS0001924 have to be zero (0) and not the letter O?

The 5th character of every IFSC code — including UTKS0001924 — 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.

IFSC Code UTKS0001924 — Islamnagar, Utkarsh Small Finance Bank, Au

About IFSC Code UTKS0001924 — Islamnagar, Utkarsh Small Finance Bank

IFSC code UTKS0001924 is the official 11-character alphanumeric identifier assigned by the Reserve Bank of India to the Islamnagar branch of Utkarsh Small Finance Bank located in Au, Bihar. 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 UTKS0001924

The 11-character code UTKS0001924 is structured in three segments the RBI uses to route every NEFT and RTGS transfer: UTKS is the bank identifier — a four-letter code that identifies Utkarsh Small Finance 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. 001924 is the branch identifier — six alphanumeric characters assigned exclusively to the Islamnagar 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.

NEFT, RTGS, IMPS, and UPI — When to Use IFSC UTKS0001924

IFSC code UTKS0001924 is required every time money moves digitally to or from the Islamnagar branch. The four transfer systems that use this code work differently — here is when to use each:

NEFT — Any Amount, Half-Hourly Batches: NEFT accepts transfers of any amount, settles in half-hourly batches, and is available 24×7 including weekends and public holidays. A transfer sent at 3:05 PM is batched at 3:30 PM and credited shortly after. The sender enters your account number + IFSC UTKS0001924 in their net banking portal.
RTGS — Minimum ₹2 Lakh, Real-Time Settlement: RTGS is the fastest bank-to-bank transfer system in India — funds arrive in the recipient's account in real time. The minimum transaction amount is ₹2 lakh; there is no upper limit. RTGS operates on RBI working days from 7:00 AM to 6:00 PM. Use IFSC UTKS0001924 with the recipient's account number to initiate RTGS to this branch.
IMPS — Instant Transfers, 24×7 Including Holidays: IMPS settles within seconds — day or night, on weekends, and even on bank holidays. Using the account number + IFSC method with UTKS0001924, you can transfer up to ₹5 lakh per transaction. IMPS is the best option for urgent transfers when RTGS hours have closed.
UPI Account Linking — One-Time Registration: When you add your Utkarsh Small Finance Bank account at Islamnagar to a UPI app like PhonePe, Google Pay, Paytm, or BHIM, the app validates IFSC UTKS0001924 in the background to confirm the account belongs to this branch. After the one-time linking, you use your UPI VPA for daily payments — the IFSC is not needed for individual UPI transactions.
Net Banking Beneficiary Registration: To transfer money to someone else's Utkarsh Small Finance Bank Islamnagar account, add them as a beneficiary in your bank's net banking using their account number + IFSC UTKS0001924. Most banks impose a cooling period of 30 minutes to 24 hours after a new beneficiary is added before the first transfer is permitted — plan ahead for time-sensitive transfers.

IFSC, MICR, and BSR Codes for Islamnagar, Utkarsh Small Finance Bank

The Islamnagar branch of Utkarsh Small Finance Bank in Au is assigned three distinct RBI codes — each used by a completely separate banking system. These codes cannot be interchanged: entering a MICR code into an IFSC field, or vice versa, will result in an immediate rejection.

IFSC UTKS0001924 — The code on this page. Used for NEFT (half-hourly batches), RTGS (real-time, ₹2 lakh minimum), IMPS (instant 24×7), and UPI account linking. Enter this code whenever a digital payment form asks for "IFSC Code."
MICR 811762006 — Used for cheque clearing, ECS auto-debit mandates, NACH forms for SIP mutual fund registration, and loan EMI auto-debit setup. Printed in magnetic ink at the bottom of your cheque leaf. View the MICR code for this branch →

All three codes identify the same physical branch at Au, Bihar. They are gateways into three entirely separate systems operated by the RBI. A form that asks for IFSC always expects the 11-character alphanumeric code that starts with four letters.

Step-by-Step: How IFSC UTKS0001924 Routes a NEFT Transfer

When a NEFT transfer is initiated to this branch, the process that IFSC UTKS0001924 enables unfolds in five steps:

Initiation: The sender enters the recipient's account number and IFSC UTKS0001924 in their net banking or mobile banking app and confirms the transfer.
Validation: The sender's bank validates UTKS0001924 against the RBI's NEFT participant master list. An invalid, deactivated, or incorrectly typed IFSC code is rejected immediately — no money moves.
Bank routing: Characters 1–4 (UTKS) identify Utkarsh Small Finance Bank as the receiving bank, routing the transfer instruction to Utkarsh Small Finance Bank's NEFT settlement account at the RBI.
Branch routing: Characters 6–11 (001924) identify the Islamnagar branch specifically, directing the credit internally within Utkarsh Small Finance Bank's systems to the correct branch ledger.
Settlement: At the next NEFT batch (every 30 minutes), the RBI debits the sender's bank and credits Utkarsh Small Finance Bank's settlement account. Utkarsh Small Finance Bank then credits the beneficiary's account at Islamnagar.

Verify IFSC UTKS0001924 Before You Transfer — Common Mistakes

Using MICR or BSR instead of IFSC: A field labelled "IFSC Code" expects exactly 11 alphanumeric characters starting with 4 letters. MICR codes (9 digits) and BSR codes (7 digits) are completely different identifiers and will be rejected if entered in an IFSC field.
Typing the letter O instead of digit 0 at position 5: The 5th character of UTKS0001924 is the digit zero (0), not the letter O. In many fonts they look identical. Entering the letter O instead of 0 will fail IFSC validation immediately.
Using a deactivated IFSC after a bank merger: When the RBI merges two banks, IFSC codes of the absorbed bank are deactivated — sometimes on a scheduled date, sometimes immediately. If Utkarsh Small Finance Bank has been involved in a merger, always verify the code on BankZop before initiating a large RTGS transfer.
Using the wrong branch's IFSC: Funds are routed to the branch identified by the IFSC — not to any branch of the same bank. IFSC UTKS0001924 routes to Islamnagar specifically. A different branch's IFSC will credit the wrong account or fail validation.
Not accounting for the beneficiary cooling period: After you add a new beneficiary with IFSC UTKS0001924 in net banking, most banks block transfers for 30 minutes to 24 hours. Add new beneficiaries in advance — don't wait until the moment you need to transfer.
