Guide to International Bank Account Numbers (IBANs)

International Bank Account Numbers (IBANs) are standardized numbers that play a key role in overseas banking. They identify bank accounts so that international financial transfers can be completed quickly and accurately.

Here, you’ll learn more about IBANs, how they work, and how they differ from other banking numbers.

What Is an International Bank Account Number (IBAN)?

An International Bank Account Number, or IBAN, is a one-of-a-kind identifier that banks use to refer to a specific bank account in any of 80+ countries around the world. In turn, banks use that info to quickly move money between accounts in different countries.

While IBANs are useful in sending and receiving funds, they aren’t used for withdrawing funds or for transferring ownership of accounts.

How Does an IBAN Work?

An IBAN is a standardized numbering system that includes up to 34 alphanumeric characters to identify accounts for transactions. While the length of an IBAN varies by country, the sequence remains the same to ensure proper routing:

•   Country code (two letters)

•   Check digits (two digits); this validates the routing numbers and accounts. It is sometimes referred to as a control code.

•   Basic Bank Account Number (BBAN); this is an alphanumeric sequence that’s up to 28 characters long and represents a country-specific bank account number (which could represent different types of bank accounts, such as checking or savings).

While the format is standardized around the globe, the length of the code varies depending on the country.
It’s worthwhile to note that when using an IBAN to send or receive payments, there might be a processing fee or commission on the transfer.

IBANs are very much a part of the daily financial flow today. You may not have had international transactions in mind when you took the time to open a bank account, but they are becoming quite common. For instance, you might do business with a vendor overseas or shop online from a company based on another continent.

IBAN Example

Here is an invented example of an IBAN:

•   GB 28 2021 6126 1431 9576 17

This would be for a UK bank. It begins with GB for “Great Britain” and has 22 characters.

Here are other examples:

Albania: AL 35 2021 1109 0000 0000 01234567
Denmark: DK 95 2000 0123 4567 89
Spain: ES 7921 0008 1361 01234 56789

IBAN vs. SWIFT Code

Both IBANs and SWIFT codes (aka Society of Worldwide Interbank Financial Telecommunications) are globally recognized and accepted banking transfer identifiers. They play a part in making sure a transfer goes through successfully, and they help keep international finance running smoothly.

They are not, however, the same set of digits. The main difference between an IBAN and a SWIFT code lies in what they identify. Whereas a SWIFT code identifies the financial institution, the IBAN points to a specific bank account. Both work in tandem to help a transaction proceed.

To provide a bit more detail, here are a few other key differences between IBANs and SWIFT codes:

•   While an IBAN works more to identify a bank, branch, and bank account numbers, SWIFT identifies a particular bank during a transaction.

•   SWIFT Codes are issued by the Society of Worldwide Interbank Financial Telecommunications, which is a member-owned cooperative. The SWIFT banking system is a messaging network that enables financial institutions around the world to talk to one another securely. IBANs, on the other hand, are issued directly by the financial institutions.

•   Whereas IBANs are alphanumeric codes that are up to 34 digits, SWIFT codes include alphanumeric code that’s either 8 or 11 characters.

Do All Countries Use IBANs?

While more than 80 countries use IBANS, not every nation does. IBANs are generally used in the majority of banks in the Eurozone and other European countries. Parts of the Middle East, the Caribbean, and North Africa also use IBANs.

Some countries, such as Austria, Croatia, France, and the Netherlands make IBANs mandatory. Other countries don’t require the use of IBANs, but it is recommended. These include Albania, Brazil, Costa Rica, and the Virgin Islands.

Lastly, there are countries that don’t use IBANs. China, New Zealand, Canada, and the U.S. fall into this camp.

When Is an IBAN Number Required?

An IBAN number is typically required for international banking transactions. It allows for the accurate transfer of funds between accounts in different countries.

If, say, you need to make a payment to a business in South America or you have bought an item at an auction in Europe, you would likely need the recipient’s IBAN to complete the transaction. With that information, the money could be moved from your checking account to the payee’s account.

How Do I Find an IBAN?

If IBANs are available in both the country you live in and in the recipient’s country, you can obtain an IBAN by reaching out to your bank or checking on your bank statement. The person you’d like to send or receive money from will also need to to get their IBAN by contacting their bank or looking at their bank statement.

If you live in the U.S. and need an IBAN to complete an international transaction, the payee will typically share their banking details for the transfer of funds, including their IBAN.

Worth noting: The IBAN website also has a handy tool to calculate your IBAN code based on your country, bank code, and account number.

The Takeaway

While the U.S. doesn’t use the IBAN (International Bank Account Number) system, when you are sending funds overseas, you’ll need the other party’s IBAN. This number contains vital information that will help the money get to the intended account in another country safely and quickly. In this way, IBANs play an important role in keeping international financial transactions flowing.

SoFi members with direct deposit activity can earn 4.00% annual percentage yield (APY) on savings balances (including Vaults) and 0.50% APY on checking balances. Direct Deposit means a recurring deposit of regular income to an account holder’s SoFi Checking or Savings account, including payroll, pension, or government benefit payments (e.g., Social Security), made by the account holder’s employer, payroll or benefits provider or government agency (“Direct Deposit”) via the Automated Clearing House (“ACH”) Network during a 30-day Evaluation Period (as defined below). Deposits that are not from an employer or government agency, including but not limited to check deposits, peer-to-peer transfers (e.g., transfers from PayPal, Venmo, etc.), merchant transactions (e.g., transactions from PayPal, Stripe, Square, etc.), and bank ACH funds transfers and wire transfers from external accounts, or are non-recurring in nature (e.g., IRS tax refunds), do not constitute Direct Deposit activity. There is no minimum Direct Deposit amount required to qualify for the stated interest rate. SoFi members with direct deposit are eligible for other SoFi Plus benefits.

As an alternative to direct deposit, SoFi members with Qualifying Deposits can earn 4.00% APY on savings balances (including Vaults) and 0.50% APY on checking balances. Qualifying Deposits means one or more deposits that, in the aggregate, are equal to or greater than $5,000 to an account holder’s SoFi Checking and Savings account (“Qualifying Deposits”) during a 30-day Evaluation Period (as defined below). Qualifying Deposits only include those deposits from the following eligible sources: (i) ACH transfers, (ii) inbound wire transfers, (iii) peer-to-peer transfers (i.e., external transfers from PayPal, Venmo, etc. and internal peer-to-peer transfers from a SoFi account belonging to another account holder), (iv) check deposits, (v) instant funding to your SoFi Bank Debit Card, (vi) push payments to your SoFi Bank Debit Card, and (vii) cash deposits. Qualifying Deposits do not include: (i) transfers between an account holder’s Checking account, Savings account, and/or Vaults; (ii) interest payments; (iii) bonuses issued by SoFi Bank or its affiliates; or (iv) credits, reversals, and refunds from SoFi Bank, N.A. (“SoFi Bank”) or from a merchant. SoFi members with Qualifying Deposits are not eligible for other SoFi Plus benefits.

SoFi Bank shall, in its sole discretion, assess each account holder’s Direct Deposit activity and Qualifying Deposits throughout each 30-Day Evaluation Period to determine the applicability of rates and may request additional documentation for verification of eligibility. The 30-Day Evaluation Period refers to the “Start Date” and “End Date” set forth on the APY Details page of your account, which comprises a period of 30 calendar days (the “30-Day Evaluation Period”). You can access the APY Details page at any time by logging into your SoFi account on the SoFi mobile app or SoFi website and selecting either (i) Banking > Savings > Current APY or (ii) Banking > Checking > Current APY. Upon receiving a Direct Deposit or $5,000 in Qualifying Deposits to your account, you will begin earning 4.00% APY on savings balances (including Vaults) and 0.50% on checking balances on or before the following calendar day. You will continue to earn these APYs for (i) the remainder of the current 30-Day Evaluation Period and through the end of the subsequent 30-Day Evaluation Period and (ii) any following 30-day Evaluation Periods during which SoFi Bank determines you to have Direct Deposit activity or $5,000 in Qualifying Deposits without interruption.

SoFi Bank reserves the right to grant a grace period to account holders following a change in Direct Deposit activity or Qualifying Deposits activity before adjusting rates. If SoFi Bank grants you a grace period, the dates for such grace period will be reflected on the APY Details page of your account. If SoFi Bank determines that you did not have Direct Deposit activity or $5,000 in Qualifying Deposits during the current 30-day Evaluation Period and, if applicable, the grace period, then you will begin earning the rates earned by account holders without either Direct Deposit or Qualifying Deposits until you have Direct Deposit activity or $5,000 in Qualifying Deposits in a subsequent 30-Day Evaluation Period. For the avoidance of doubt, an account holder with both Direct Deposit activity and Qualifying Deposits will earn the rates earned by account holders with Direct Deposit.

Members without either Direct Deposit activity or Qualifying Deposits, as determined by SoFi Bank, during a 30-Day Evaluation Period and, if applicable, the grace period, will earn 1.20% APY on savings balances (including Vaults) and 0.50% APY on checking balances.

Interest rates are variable and subject to change at any time. These rates are current as of 12/3/24. There is no minimum balance requirement. Additional information can be found at https://www.sofi.com/legal/banking-rate-sheet.
