What Is an IBAN Number and How to Find It?

One incorrect character in an IBAN can result in delays, rejected transfers, or even the loss of funds. For businesses and individuals sending money across borders, understanding the meaning of IBAN, its structure, and functions is essential.

This guide explains how the system works, how to find your IBAN number and use it correctly to ensure your payments arrive safely and on time.

What Is an IBAN Number?

IBAN stands for International Bank Account Number. Originally developed in Europe in 1997, the IBAN format is now adopted in over 80 countries.

It includes essential account details in a structured format to help banks and financial institutions automatically validate and route international payments. Without it, transfers may be delayed, rejected, or misdirected.

What does IBAN mean? Each IBAN is unique to the account holder and includes information, such as the country of the account, the specific bank and branch, and the individual account number. This standardised format reduces human error—with it, funds reach the correct destination quickly and securely.

The Format of an IBAN Number

An IBAN consists of up to 34 alphanumeric characters, which are grouped by several components:

• Country Code: A two-letter ISO code that represents the country where the account is held (e.g. CH for Switzerland, FR for France).
• Check Digits: Two numerical digits that allow banks to verify that the IBAN is valid before processing the payment.
• Bank Identifier Code: A sequence of numbers or letters that identifies the financial institution. This can include a bank code, as well as a branch code or sort code.
• Account Number: The domestic account number or Basic Bank Account Number (BBAN), which identifies the customer’s account within the bank.

Example of an IBAN Number

Here are two examples that show how the format varies by country:

Switzerland CH7431101111011000246 CH = country code that indicates the company is based in Switzerland 74 = check digits 3110 = bank code 111101 = branch code 011000246 = account number

France FR7630006000011234567890189 FR = country code (France) 76 = check digits 3000 = bank code 600001 = branch code 011234567890189 = account number

Is an IBAN the Same as a SWIFT Code?

While similar in purpose, they’re slightly different. A SWIFT code, also known as a BIC code, directs the payment to a specific bank, and an IBAN indicates a precise account at the financial institution.

Metaphorically speaking, the “address” differs: a SWIFT/BIC routes the message to the right building, while an IBAN number directs it to the right door.

Feature	IBAN	SWIFT/BIC Code

Format Standard	ISO 13616.	ISO 9362.
Structure	Up to 34 alphanumeric characters: 2-letter country code 2 check digits Up to 30-character Basic Bank Account Number (BBAN).	8 or 11 alphanumeric characters: 4 letters (bank code) 2 letters (country code) 2 letters/digits (location code) Optional 3 letters/digits (branch code).

Why Do I Need an IBAN?

Setting up an account with an IBAN assigned to it is an essential step that businesses operating globally should take. It ensures your funds reach the correct destination by identifying the country, bank, and specific account. For businesses, an IBAN helps reduce errors, speeds up reconciliation, and supports compliance with global payment standards.

How Do I Find and Check an IBAN?

Before sending or receiving an international payment, it’s important to locate and verify your IBAN number. Below you’ll find several pieces of advice.

Check Your Bank Statement

The fastest way to find your IBAN code is on your bank statement. Most institutions include it in the account summary section alongside your name, account number, and BIC/SWIFT code. This applies to both printed and PDF statements.

Check Your Online Banking

Log in to your online banking platform or mobile app. Your IBAN is typically listed under your account details—check sections related to international transfers. Some banks also provide a “copy” button for pasting when making payments.

Contact Your Bank

If, for some reason, you didn’t manage to locate your IBAN, we advise reaching out to your bank. Call or send a message through their app or website. Bank representatives can confirm the correct IBAN linked to your account and help you avoid errors.

Check IBAN Number Length

Each country using IBANs has a fixed character length—for example, 22 characters in the UK, 27 in France, and 21 in Switzerland. If your IBAN doesn’t match your country’s standard, double-check with your provider.

What if an Incorrect IBAN Number Is Used?

Using the wrong IBAN can lead to serious issues. In most cases, the payment will be automatically rejected and returned to the sender, but not always.

If the incorrect IBAN is valid and linked to a different account, the funds may be sent to another individual. Alternatively, the transaction might be held up while the bank investigates the discrepancy.

These delays can range from a few hours to several days, depending on the provider and the country in which the service is provided. To avoid disruptions and potential fees, always double-check the IBAN code beforehand.

Which Countries Use IBANs?

As of today, 86 countries use the IBAN system for cross-border transactions. These include all EU and EEA nations, as well as countries in the Middle East, North Africa, and parts of the Caribbean and South America. Examples include:

• Germany: DE89370400440532013000
• France: FR7630006000011234567890189
• United Arab Emirates: AE070331234567890123456

Countries like the United States, Canada, Australia, and most of Asia do not use IBANs. Instead, they rely on alternative systems such as SWIFT/BIC codes and local routing numbers.

How Long Does an International Money Transfer Take

International transfers typically take from 1 to 5 business days, depending on the currencies involved, the destination country, and the banks processing the payment. Delays can occur due to time zone differences, compliance checks, or public holidays.
