Remitly FAQ

What information is required to calculate an IBAN?

The details you need depend on your country. Most banks use a mix of your local account number, bank code, or sort code to create your IBAN. For example:


  • In the UK, you’ll need your sort code and account number.
  • In Austria, it consists of your bank code, account number, and a national check digit.
  • In Bulgaria, you may need your bank code, branch code, account type, and account number.
When you select your country in the IBAN calculator, we’ll show you exactly which fields to fill in.

Are IBANs case-sensitive or space-sensitive when validating?

No—IBANs work the same with or without spaces and regardless of letter case. Just make sure all characters are correct.

When is an IBAN required?

You’ll need an IBAN when sending money to countries that support the IBAN system—mainly in Europe, along with parts of the Middle East, Asia, and Latin America. The IBAN helps ensure that funds reach the correct bank account and is often required for receiving international payments.

What is the format of an IBAN?

An IBAN (International Bank Account Number) is a standardized series of letters and numbers used to identify bank accounts across borders. While the exact format varies by country, every IBAN includes:

  • A two-letter country code (like GB for the UK or DE for Germany)
  • Two check digits to help verify the number
  • A mix of bank codes, branch identifiers, and your account number
IBANs can be up to 34 characters long, depending on the country.

When using our calculator, we’ll structure the IBAN correctly based on your country’s format.

How do you identify the account number in the IBAN?

The account number is typically located at the end of the IBAN, although its exact position varies depending on the country's IBAN format. Each country has a specific structure that determines where the account number appears.

For example:

  • In the UK, the account number is the last 8 digits of the IBAN.
  • In Germany, it's typically the last 10 digits.
To avoid confusion, it's best to check your country's IBAN structure. Our IBAN examples and calculator can help break it down so you can see where your account number fits in.
