IFSC validator

The canonical pattern is ^[A-Z]{4}0[A-Z0-9]{6}$.

Use format validation in onboarding forms before calling payment rails or banking APIs.

1. Paste an 11-character IFSC code (case is normalised to uppercase).
2. The tool checks the structure: four-letter bank code, a fixed 0, then a six-character branch identifier.
3. A pass means the code is well-formed and safe to submit to a payment form.

The first four letters identify the bank; the trailing six characters identify the specific branch.

Structural validity is not the same as existence — a well-formed code can still point to a branch that has merged or closed, so always confirm against the bank's official directory or RBI data before settling a transfer. Banks occasionally retire and reissue branch codes after mergers. The check runs entirely in your browser; the IFSC you enter is never uploaded.
