How it works

  1. 1

    Paste the IBAN

    Type or paste any IBAN. Spaces and lower case are fine — they are cleaned up automatically.

  2. 2

    Read the checks

    Each check shows a tick or a cross: country length, bank code, account checksum and the IBAN check digits.

  3. 3

    Copy the details

    For a valid IBAN you can copy the formatted IBAN or, where available, the BIC.

Instant & 100% private — nothing is uploaded

Every calculation runs locally in your browser. The income, balances and goals you enter stay on your own device and are never sent to a server — nothing is stored, logged or shared.

Frequently asked questions

What does the IBAN check digit prove?
It is a mod-97 checksum over the whole IBAN. If it matches, the IBAN has no typo in any character. It does not prove the account exists — only that the number is internally consistent.
Why is there no BIC for my IBAN?
The bank name and BIC are shown for German accounts, where an official free bank directory is available. For other countries the IBAN is still fully validated, but a BIC is not shown.
Is the IBAN I enter sent anywhere?
No. The whole check runs in your browser. Nothing you type is uploaded, logged or stored.
