IBAN calculator

An International Bank Account Number (IBAN) is the standardised way to identify a bank account across borders. It packs the country, the bank, and the account into one string with two check digits, so international transfers land where they should.

Pick a country and enter the local bank details: the calculator assembles the IBAN and computes its check digits instantly, right in your browser. Switch to Check to test an IBAN you already have. Nothing you type leaves the page.
