What an IBAN is made of

An International Bank Account Number starts with a two-letter country code and two check digits, followed by the domestic account details, which the country lays out its own way. Germany fits a bank code and an account number into 22 characters; Lebanon uses 28.

Because each country publishes its own length and layout in the IBAN registry, a number that is one character short, or has a letter where the country only uses digits, can be rejected before any arithmetic is done.

Formats by country

How the check digits catch typos

The two digits after the country code are computed from everything else using the ISO 13616 mod-97 method. Change any single character, or swap two neighbouring ones, and the check fails. That catches nearly every typing mistake.

Some countries add a national check digit inside the account number as well. Where one is defined, it is checked too.

What a pass does not tell you

A valid IBAN is well-formed. It does not mean the account is open, and it does not mean it belongs to the person you intend to pay. Check the name with the recipient; in the euro area and the UK, banks now compare the name with the account before a transfer goes.

IBAN length and format by country

124 countries and territories: 97 listed in SWIFT’s IBAN registry, and 27 where an IBAN format is in national use but not in the registry. In the format, kk is the check digits, n a digit, a a letter and c a letter or digit.

Correct bank details are half of a good transfer. The other half is what it costs: the fee and the exchange-rate margin.

FAQ

Common questions

Does a valid IBAN mean the account exists?

No. The check confirms the IBAN is well-formed and that its check digits match. Only the receiving bank knows whether the account is open and who holds it.

Does the US use IBANs?

No. US accounts are identified by a nine-digit routing number and an account number. To receive money from abroad, a US bank gives you its SWIFT/BIC code as well.

Is it safe to type an IBAN here?

The check runs entirely in your browser. The IBAN is not sent to us or to anyone else, and it is not stored.

Do I still need a BIC if I have the IBAN?

Within the SEPA area, no: the IBAN alone is enough for a euro transfer. For transfers elsewhere, many banks still ask for the BIC of the receiving bank.
