Check an 11-character IFSC: four-letter bank code, the zero, and the branch code
Runs in your browser. Nothing you type is sent anywhere. Updated on 25 Oct 2026.RBI defines the IFSC as an 11-character code: four letters for the bank, the digit 0, and six characters for the branch. Paste one before an NEFT or RTGS transfer to catch the commonest slip, a letter O typed for the zero. The check covers the format only, because an IFSC has no check digit. RBI’s IFSC search, linked below, gives the bank, branch and address.
The page opens with IFSC selected; paste the 11-character code into the box.
Read the Bank, Zero and Branch parts; a letter O typed for the zero is flagged.
Press Copy for the cleaned code, or Copy link to share the check with the code in it.
Find the bank, branch and address with IFSC search on the RBI website, linked below.
Most Indian identifiers have a structure you can check before a form is submitted. This page reads six of them, tells which one you pasted from its shape, names each part, and tests the check digit where one exists and is published.
| ID | Length | Built from | Check digit tested here |
|---|---|---|---|
| GSTIN | 15 | State code, PAN, entity number, Z, check | Yes, base 36 |
| PAN | 10 | Series, holder type, name initial, number, check | No, formula not published |
| Aadhaar | 12 digits | 11 random digits and a check | Yes, Verhoeff |
| IFSC | 11 | Bank code, 0, branch code | None defined |
| UPI ID | Varies | Name, @, handle | None defined |
| PIN code | 6 digits | Region, sub-region, district, post office | None defined |
For a GSTIN the page shows the arithmetic behind the check character, position by position. The state code is read against the GST portal's list, and the embedded PAN's fourth letter gives the holder type: P for an individual, C for a company, F for a firm, and so on.
The rest of the article, and all 6 questions about India ID Number Validator, are on the India ID Number Validator page.
Each of the first 14 characters becomes a number from 0 to 35 (digits, then A as 10 up to Z as 35). Alternate characters are multiplied by 1 and 2, each product adds its quotient and remainder by 36 to a total, and the check character is 36 minus the total's remainder, modulo 36. The page shows every step.
The fourth character of a PAN gives the type of holder: P for an individual, C for a company, H for a Hindu Undivided Family, F for a firm, A for an association of persons, T for a trust, B for a body of individuals, L for a local authority, J for an artificial juridical person and G for government.
No. Every check runs in your browser and the page makes no network request with what you type. An Aadhaar number is shown masked to its last four digits, nothing typed is kept in browser storage, and share links never include an Aadhaar number, PAN, GSTIN or UPI ID.
RBI defines the IFSC as 11 characters: four letters for the bank, then the digit 0, then six characters for the branch. The zero is fixed, so an IFSC with a letter O in fifth place has been mistyped. An IFSC has no check digit, so RBI's IFSC search is the way to confirm the branch.
