Chase does not issue IBAN numbers to U.S. customers

If you bank with Chase in the United States, you will not have an IBAN number. Chase uses the SWIFT/BIC code and routing number system instead. An IBAN (International Bank Account Number) is a standardized format used primarily in Europe, the Middle East, and some other regions — but not in the U.S. banking system.

The confusion arises because IBANs look similar to the account information you need for international transfers, but they serve a different purpose and follow a different structure. If someone asks you for your IBAN to send money to your Chase account, they may be unfamiliar with how U.S. banks operate, or they may be asking for the wrong information.

Key Takeaways

  • Chase U.S. accounts do not have IBAN numbers; the U.S. banking system uses routing numbers and account numbers instead.
  • For international transfers into a Chase account, you will need your SWIFT/BIC code, routing number, and account number.
  • If you have a Chase account outside the U.S., that account may have an IBAN, but it operates under different banking rules.
  • Providing the wrong account information to an international sender can delay or reject a transfer, so confirm what format the sender actually needs.

What you need instead: SWIFT code and routing number

When someone outside the U.S. wants to send money to your Chase account, they will ask for your SWIFT code (also called BIC code), your routing number, and your account number. These three pieces of information work together to identify your bank and your specific account.

Chase's SWIFT code is CHASUS33 for most U.S. locations, though some branches use regional codes. Your routing number is a nine-digit code specific to the Chase branch where your account is held — you can find it on the bottom left of your checks, or by logging into your Chase account online. Your account number is the unique identifier for your specific account and appears on your statements and checks.

International senders use these three pieces of information to route money through the SWIFT network, which connects banks across countries. The process is slower and more expensive than domestic transfers, typically taking three to five business days and involving multiple intermediary banks.

Why the U.S. doesn't use IBANs

The United States developed its banking infrastructure before IBANs existed. The routing number and account number system has been in place since the 1910s and works reliably within the U.S. financial system. When international standards for bank account numbers were created in the 1990s, the U.S. chose not to adopt them because the existing system was already entrenched and functional.

IBAN adoption would have required a massive overhaul of U.S. banking infrastructure, and there was no regulatory pressure to do so. Other countries, particularly in Europe, adopted IBANs to standardize cross-border payments within the European Union and beyond. The U.S. continues to use its own system, which is why you will encounter this difference when dealing with international transfers.

If you have a Chase account outside the U.S.

Chase operates in several countries outside the United States, including the United Kingdom, Japan, and others. If you hold a Chase account in one of these countries, that account may indeed have an IBAN, because those countries use the IBAN standard.

For example, a Chase account in the UK would have a UK IBAN that begins with "GB". The structure and use of that IBAN would follow UK banking rules, not U.S. rules. If you are unsure whether your Chase account is subject to IBAN requirements, contact the local Chase branch where you opened the account or check your account statements.

How to handle a request for your IBAN

If someone asks for your IBAN to send you money to your U.S. Chase account, politely clarify that U.S. banks do not use IBANs. Provide them with your SWIFT code, routing number, and account number instead. You can find all three of these in your Chase online banking portal under account details, or by calling Chase customer service.

Be cautious if someone insists on an IBAN or claims they cannot process a transfer without one. This may indicate they are unfamiliar with U.S. banking, or it could be a sign of a scam. Legitimate international senders will accept the standard U.S. account information and know how to use it.

What happens if you give the wrong information

If you accidentally provide an IBAN format or incorrect account information to an international sender, the transfer will likely be rejected by the receiving bank. The money may be returned to the sender after a delay of several days or weeks, or it may be held in a suspense account while the bank tries to contact you.

In some cases, the sender's bank may charge a fee for the rejected transfer, and you may not receive the funds at all. This is why it is important to double-check the account information you provide and to confirm with the sender that they have the correct format before they initiate the transfer.

Frequently Asked Questions

Can I request an IBAN from Chase for my U.S. account?

No. Chase does not issue IBANs for U.S. accounts because the U.S. banking system does not use them. If you need to receive an international transfer, provide your SWIFT code, routing number, and account number instead. These are the standard identifiers for U.S. bank accounts.

Is my Chase routing number the same as an IBAN?

No. Your routing number is a nine-digit code that identifies your specific Chase branch, while an IBAN is a longer alphanumeric code used in other countries. They serve similar purposes but are not interchangeable. For international transfers, you need both your routing number and your account number, along with your SWIFT code.

What if the sender's bank says they need an IBAN?

Contact Chase customer service and explain the situation. Chase can provide you with the correct information in the format their system uses. If the sender's bank truly cannot process a transfer without an IBAN, the transfer may not be possible through that bank, and you may need to explore alternative payment methods or ask the sender to use a different bank.

Do I need an IBAN to send money from my Chase account internationally?

No. When you send money from your Chase account to someone outside the U.S., you will provide their IBAN (if they are in a country that uses IBANs) or their local account information. Chase will handle the conversion and routing on your end. You do not need an IBAN yourself.
