IFSC Format Checker

Check whether a bank IFSC code is structurally valid — four bank letters, a zero, and six branch characters.

How it works

An IFSC is 11 characters: the first four are the bank code, the fifth is always 0 (reserved), and the last six identify the branch. This confirms the shape is right before you put it on an invoice; to find the branch for a given IFSC, use your bank's or the RBI's lookup.

Frequently asked

What is the structure of an IFSC code?: Four letters for the bank, a zero, then six characters for the branch — 11 in total, e.g. HDFC0001234. The fifth character is always zero.
