What a Chase IBAN number is and when you need it

An IBAN (International Bank Account Number) is a standardized code that identifies your specific bank account for transfers outside the United States. Chase issues IBAN numbers to customers who hold accounts at Chase branches located outside the U.S. — primarily in Europe, the Middle East, and Asia.

If your Chase account is held at a U.S. branch, you do not have an IBAN. Instead, U.S. wire transfers use a routing number and account number. You need an IBAN only if you are sending money from or receiving money into a Chase account in a country that uses the IBAN system, or if a foreign bank is asking you for one to complete a transfer.

The IBAN format varies by country. A Chase IBAN in the United Kingdom, for example, starts with "GB" and contains 22 characters total. A Chase IBAN in Germany starts with "DE" and contains 22 characters. The first two letters always indicate the country where the account is held.

Key Takeaways

  • Chase IBAN numbers are issued only for accounts held at Chase branches outside the United States, not for U.S. Chase accounts.
  • Your IBAN appears on your Chase bank statements and in your online banking portal under account details or account information.
  • The IBAN format changes by country and always begins with a two-letter country code followed by numbers and letters specific to your account.
  • If you cannot find your IBAN online, you can contact your local Chase branch directly or call the international customer service line for your country.

Where to find your IBAN in your Chase account

The fastest way to locate your IBAN is through your Chase online banking portal. Log in to your account, navigate to the account details or account information section, and look for a field labeled "IBAN" or "International Bank Account Number." Most Chase banks display this information prominently on the main account overview page.

Your IBAN also appears on your printed bank statements. Look near the top of the statement where your account number and routing number are listed — the IBAN is typically printed alongside these details. If you have statements from the past three months, any of them will show your IBAN.

Some Chase branches in Europe and Asia allow you to read an account verification letter directly from the online portal. This document contains your full IBAN, BIC code (also called SWIFT code), and account holder name in a format that foreign banks accept as proof of account ownership.

How to contact Chase if you cannot locate your IBAN

If your online portal does not display your IBAN or you do not have access to recent statements, contact your local Chase branch by phone or in person. Have your account number and photo ID ready when you call. The branch staff can confirm your IBAN within minutes and may offer to email or mail it to you.

Chase also operates international customer service lines in countries where it maintains branches. The phone number for your country's customer service is usually printed on the back of your Chase debit or credit card. When you call, specify that you need your IBAN for an international wire transfer.

If you are outside your home country and cannot reach your local branch, you can contact Chase's international wire transfer department through the main Chase website for your country. Response times vary, but most inquiries are answered within one business day.

What information you need alongside your IBAN

An IBAN alone is not always enough to complete an international wire transfer. Most foreign banks also request your BIC code (also called a SWIFT code), which identifies Chase as your bank and your specific branch. Your BIC code is typically eight or eleven characters long and appears on your statements or in your online account details.

You will also need to provide your full name as it appears on your Chase account, the amount you are transferring, and the currency (usually EUR, GBP, or another currency depending on your account location). Some banks request additional details such as your account holder's address or date of birth.

If you are receiving a wire transfer into your Chase account, provide the sender with your IBAN, BIC code, and full account holder name. Do not share your PIN, password, or full account number with anyone requesting a wire transfer.

IBAN versus routing number: which one to use

Use your IBAN when sending or receiving money internationally, particularly if the transfer involves a bank outside the United States or if the receiving bank specifically requests an IBAN.

Use your routing number (a nine-digit code) and account number only for domestic U.S. transfers between American banks. If you hold a Chase account in the U.S., you will never need an IBAN for any transfer within the United States.

If you are unsure which code to provide, ask the bank or institution requesting the transfer. They will tell you whether they need an IBAN, routing number, or both. Providing the wrong code will cause the transfer to fail or be delayed while the receiving bank contacts you for correction.

Common reasons your IBAN might not appear online

Some Chase online banking portals do not display the IBAN in the main account overview. Instead, it may be located in a separate section labeled "International Transfers," "Wire Transfer Details," or "Account Verification." Check these sections before contacting the bank.

If your account is very new (less than one week old), Chase may not have generated your IBAN yet. Wait a few business days and check again. If your account has been open for more than a week and the IBAN still does not appear, contact your branch — this is unusual and may indicate a technical issue with your online portal.

Some Chase accounts held in certain countries or regions may not have an IBAN if they are structured differently or if the country does not use the IBAN system. Your branch can confirm whether your specific account type is issued an IBAN.

Frequently Asked Questions

Can I use my IBAN for transfers within the United States?

No. IBANs are used only for international transfers. U.S. banks do not recognize or accept IBAN numbers. For domestic U.S. transfers, use your nine-digit routing number and your account number instead.

Is my IBAN the same as my account number?

No. Your account number is part of your IBAN, but they are not the same. Your IBAN includes your account number plus additional digits that identify your country and bank branch. An IBAN is typically 22 to 34 characters long, while an account number is usually 8 to 17 digits.

What if the bank receiving my transfer says my IBAN is invalid?

Double-check that you have copied your IBAN correctly — even one wrong letter or number will cause the transfer to fail. Verify the IBAN directly from your bank statement or online portal rather than relying on memory. If the IBAN is correct, contact your Chase branch to confirm it is active and properly formatted for international transfers.

Do I need both an IBAN and a BIC code to send money internationally?

Most international transfers require both, though some banks accept transfers with only an IBAN. Ask the receiving bank which information they need before you initiate the transfer. Having both codes on hand prevents delays.
