Swift/BIC Checker Guide – Validate Bank Codes with Ease

What Is a SWIFT/BIC Code?

A SWIFT/BIC (Bank Identifier Code) is a unique identifier assigned to financial institutions by the SWIFT network, used for international wires and interbank messaging. It can be 8 or 11 characters: 4‑letter bank code + 2‑letter country code + 2‑letter/numeral location code + optional 3‑character branch code. For example, ICBKCNBJ represents the Beijing head office of ICBC.

How to Use This Swift/BIC Checker

Three simple steps to verify your BIC format:

1. Paste or type an 8‑ or 11‑character SWIFT/BIC code (case‑insensitive) into the input field.
2. Click the “Validate” button.
3. Read the result – the checker will tell you whether the format is valid.

You can test with the example codes above. If the input is incorrect (wrong length or invalid characters), you’ll get a clear warning.

This tool is completely free, no registration required – perfect for finance staff, cross‑border payment users, and anyone needing a quick BIC sanity check.

Frequently Asked Questions

1. Does the Swift/BIC Checker confirm that the bank actually exists?

This tool validates the format against ISO 9362 standards. A “valid” result means the structure is correct. To confirm whether the bank is an active SWIFT participant, you’ll need to consult the official SWIFT directory or contact the beneficiary bank.

2. Why does my code show as invalid?

Possible reasons: length is not 8 or 11; it contains disallowed characters (only letters and numerals are allowed, and letters are typically uppercase); the country code is not a valid ISO 3166‑1 two‑letter code; or the branch part is malformed. Double‑check your input, or try one of the example codes to ensure the checker is working.

3. Can this checker handle bulk BIC validation?

This page is designed for single‑code validation. If you need batch processing, feel free to reach out to us.

4. What’s the difference between 8‑digit and 11‑digit BICs?

An 8‑digit BIC identifies the head office or primary institution, while an 11‑digit BIC includes a 3‑character branch code to pinpoint a specific office. Providing the full 11 digits can speed up processing, but transfers using the 8‑digit head office code usually succeed as well.

5. Do I have to pay for this?

No – it’s entirely free. OkeyTool aims to offer practical online utilities for everyday use.
