Why IBAN numbers were created
The IBAN system was designed to simplify the transfer of money overseas—but they’re used in some countries for domestic transfers as well. Separate from your account number and sort code, they include information about the account holder’s specific bank, the country that this bank is in, and a combination of other account details. This added level of coded security reduces transaction errors, rejected payments, and transfer delays across borders. IBANs can only be used to send or receive funds, and they can’t be used for other transactions, such as cash withdrawals.IBAN characters, explained
Each character set of an IBAN number shares a specific piece of information with banks. They begin with a two-letter country code—such as ‘FR’ for France and ‘DE’ for Germany. The next two digits are control checks, acting as a security layer specific to your bank. The remaining numbers are domestic banking details, also known as your Basic Bank Account Numbers (BBAN). The BBAN information will typically include a bank code and branch reference, as well as the account number—although formats can differ across IBAN regions.How an IBAN number works
When you make a cross-border transaction, the characters that make up your IBAN number are run through the payments system used by your bank. By verifying the numbers and letters against their database, the system is able to confirm the sender’s account and that of the recipient. Special algorithms are used to digest and check the account information. If it’s valid, the payment will be processed.How an IBAN number works

Who uses IBAN numbers?
Although IBAN numbers were originally designed for payments between Eurozone banks, they’re now used in 70+ countries worldwide. In places like Canada or the US, IBAN numbers haven’t been adopted, and they’re not required for transferring funds to those countries. However, they are needed when making an international transaction to a country that has adopted the system.

Where can I find my IBAN number?
Here are some tips for finding you IBAN number:
- Check your debit card! Some countries display IBANs directly on their bank cards, while others don’t.
- Get in touch with your bank to request it—as long as you’re in a dedicated region, they’ll be able to provide you with the details you need.
- Check the top of bank statements or your bank’s online banking app. For example, N26 account holders can access their bank IBAN number right in their app.

How to use an IBAN number generator
You can also find out your IBAN using an online IBAN calculator. Because the system is an internationally accepted coding system, the calculator tool is able to generate it for you using the preset configuration set by the system and your country; simply enter your country code, sort code, and account number. You can also validate that the number your recipient has provided is active via an IBAN number checker.How safe is an IBAN?
Using an IBAN number to transfer funds is considered safe by Eurozone finance regulators, and is routinely used to make payments across borders. The key security benefit is that although other consumers can make money transfers into your account using your IBAN, it’s not possible to withdraw money or transfer funds from your account. This means that there is no security risk for your funds.The difference between IBAN, SWIFT, and BIC codes
When making an international payment, you may be asked for an IBAN number, SWIFT code, or a BIC. SWIFT codes and Bank Identifier Codes (BIC) do the same job—they identify the specific country, bank, and branch your recipient's account is held with. An IBAN identifies the specific account details involved in the transaction, as well as the bank and branch. A BIC or SWIFT code is up to 11 characters
