About IBANs.

What is an IBAN number?

An International Bank Account Number (IBAN) is a standardised format used to identify bank accounts when sending or receiving payments across borders. It combines a country code, check digits, and a country-specific bank and account identifier.

The length and structure of an IBAN vary by country, but every valid IBAN follows rules designed to reduce payment errors. For example, an IBAN from the United Kingdom begins with GB, while one from Germany begins with DE.

What does a valid IBAN number look like?

A valid IBAN follows the length and format required by its country. It always starts with a two-letter country code, followed by two check digits, then a country-specific combination of letters and numbers for the bank and account details.

Here's an example of an IBAN:

How to check international bank account numbers

1

Use this IBAN checker to validate the structure and format of an IBAN.

2

Confirm the IBAN with your recipient. This is essential to ensure you're sending money to the right person and that the account is active.

3

Automate your payments instead of typing them in manually. A single typo can send funds to the wrong account. Create payments directly from your accounting and payroll software to prevent errors.

Using an IBAN checker isn't enough to protect your funds

You should always check with the recipient.

An IBAN checker can confirm that the number follows the correct format, but it cannot verify account ownership or detect every type of payment fraud. Criminals may provide a valid IBAN belonging to an account they control, particularly after intercepting or changing invoice details.

For new beneficiaries or changes to bank details, use a trusted contact method to verify the information independently. Call a known number rather than one included in a suspicious email, and keep a clear approval process for payment-detail changes.
