Best Practice: Verify IFSC From Two Independent Sources Before Transferring

Why Single-Source Verification Is Insufficient

If you verify an IFSC only from what the beneficiary told you verbally or typed in a message, you are trusting a communication channel that could contain a typo, an outdated code, or in fraud cases, a deliberately wrong code. Adding a second independent verification source like the RBI-sourced lookup on Bank Utils creates a check that is independent of the beneficiary's input.

Source 1: Beneficiary-Provided Documents

Ask for a cancelled cheque or a scanned copy of the passbook showing the account number and IFSC. These are printed directly by the bank for that specific account and are the most reliable beneficiary-side document. A bank letter on letterhead confirming account details is equally reliable. Verbal or typed messages from the beneficiary are the least reliable source.

Source 2: Independent Branch Lookup

Cross-verify the IFSC using Bank Utils or the bank's official branch locator by searching for the bank name, state, and branch name. The result should match the IFSC on the beneficiary's document. If they differ, investigate before proceeding a mismatch usually means a bank merger has changed the code, the branch name has changed, or the document is outdated.

Making Verification a Routine Step

One-time verification for a new beneficiary is important, but beneficiary bank details also change. When a vendor or employee changes their bank account, treat the new details as an entirely new verification task re-request documentation, re-verify the IFSC, and re-confirm through the lookup tool before processing the first payment to the new account.

Protecting Against Fraud

Business email compromise (BEC) fraud specifically targets the beneficiary bank detail update step. Fraudsters impersonate vendors or employees via email and request a bank account change. An incoming bank detail change request must always be verified by calling the vendor or employee on a number already in your records not a number provided in the same email requesting the change. IFSC verification is part of this fraud prevention protocol.

Automation in Payroll and Accounts Payable

For teams processing payments at volume, the verification discipline should be built into the workflow system rather than relying on individual memory. Payroll and accounts payable software can flag new or recently changed bank details for mandatory manual review before the first payment. The IFSC lookup step should be a required checkbox, not an optional one.
