Check the structure of a SWIFT BIC code

Check the structure of a SWIFT BIC code. Useful for developers and administrators checking data before an import, form submission or integration.

Check the structure of a SWIFT BIC code. The answer appears right away in your browser and is ready to use, with no account, upload or stored data.

How to use

Enter a BIC code of eight or eleven characters, using uppercase letters and keeping the blocks in the correct order.
Check that the first four characters are letters, the country part has two letters, and the remaining characters are alphanumeric.
Run the verification to see whether the structure matches the expected SWIFT BIC format.
If the result reports a problem, correct the code or clear the field and start again.

Example

A developer prepares a bank transfer form and tests the value ABCDFRPP. They run the check to make sure the sample follows the BIC structure before using it in automated tests.

Input

ABCDFRPP

Limits and formats

The tool checks the code's shape, not whether the bank exists or whether the account is valid.
A valid BIC can have eight or eleven characters; any other length should be treated as suspicious.
Lowercase letters, spaces and special characters are outside the usual format and may cause the check to fail.
A correct structure does not guarantee that a bank will accept a payment; other details are still required.
If you import a file, remove spaces and empty lines around the code.

Where processing happens

The verification runs locally in your browser. The code you enter stays on your device and is not uploaded or stored elsewhere. No connection to a banking database is used for this check.

Frequently asked questions

What is the structure of a BIC?

A BIC starts with four letters for the bank, then two letters for the country, two alphanumeric characters for the location, and optionally three characters for a branch. The tool checks this layout.

Can I type the BIC in lowercase?

The standard format uses uppercase letters. Although some systems may accept lowercase, entering the code in capitals avoids an unnecessary validation failure.

Does a verified BIC prove the account exists?

No. The check only examines the BIC structure. It does not confirm the bank, the account, or whether a future transfer will be accepted.
