IFSC / Bank Lookup API Integration
Resolve any Indian bank branch from an IFSC code — used for payouts, onboarding and validation.
What IFSC / Bank Lookup API integration does
IFSC lookup resolves any Indian bank branch from its eleven-character code, returning the bank, branch, address and the payment systems that branch supports. It is a small integration with an outsized effect on payout reliability.
The failure it prevents is expensive out of proportion to its size. A payout initiated against an invalid or mistyped IFSC fails at the bank, the money is returned days later, and in the meantime a customer, vendor or claimant believes they have been paid. Validating the code at data entry converts a multi-day reconciliation problem into an inline form error. Shipping a static IFSC list instead is a slow-burning version of the same problem, because branch data genuinely changes — mergers, closures and re-codings happen regularly.
What teams build with it
Beneficiary validation
Validate the IFSC at the point the customer enters it, so an invalid code is a form error rather than a failed transfer.
Payout preparation
Confirm bank and branch before initiating vendor, refund or claim disbursements.
Onboarding data quality
Auto-fill bank and branch names from the code to reduce typing and mismatches.
Master data cleanup
Re-validate stored bank details across an existing customer or vendor base to catch codes invalidated by mergers.
Endpoints included
GET/ifsc/v1/{code}Returns branch details for an IFSC code.

}What you need before we start
- The IFSC codes to validate
- A form or API surface where validation runs inline
- A caching policy, since branch data changes slowly
How we deliver it
- Inline validation wired into your onboarding or payout form
- Sandbox integration and response mapping
- Caching layer for frequently used codes
- Optional batch re-validation across an existing master

IFSC / Bank Lookup API integration — FAQs
What does the lookup return?
Bank, branch, address and supported payment systems for the given IFSC code.
Why not just bundle a static IFSC list?
Because branch data changes — mergers, closures and re-codings happen regularly — and a stale list becomes a slow-burning source of failed payouts.
Is it free to use?
It is a public-access rail with no scheme licensing cost; you pay for the integration and throughput.
