On a bank statement, the IBAN sits in the account summary block at the top of the first page, printed next to or just below your name and your domestic account number. It’s an alphanumeric string of up to 34 characters, beginning with two letters that identify the country. If your bank is in a country that uses the IBAN system, every paper statement, PDF, and online banking screen will show it somewhere in the account details. If your bank is in the United States, it won’t be there at all, because U.S. banks don’t issue IBANs.
Where It Appears on the Page
Look at the header of the statement, in the same box that shows your name and address. The IBAN is usually labeled plainly as “IBAN” and printed as a single line of letters and digits, sometimes broken into groups of four with spaces for readability. On a multi-page statement, some banks repeat it in the footer of every page.
On digital statements and inside online banking, the same number lives in the account details or account information panel. Mobile apps generally tuck it under a heading like “account details” or behind a button on the main account screen. If you don’t see it immediately, check the profile or settings area for the account.
You’ll almost always see a second code printed close to the IBAN, labeled BIC or SWIFT. That one identifies your bank, not your account. It’s shorter, eight or eleven characters, and people receiving international transfers often need both numbers, so it helps to copy them down together.
How to Recognize an IBAN
The format is standardized under ISO 13616.1International Organization for Standardization. ISO 13616-1-2020 Every IBAN starts with a two-letter country code (DE for Germany, FR for France, GB for the United Kingdom, and so on), followed by two numerical check digits. Everything after that is the Basic Bank Account Number, which contains your bank’s identifier and your individual account number packed into one string.
Length varies by country, because each national account-numbering scheme is a different size. A German IBAN runs 22 characters, a British IBAN also 22, a French IBAN 27.2IBAN.com. IBAN Examples, Structure and Length The ceiling under the standard is 34. Only uppercase letters and digits are valid. Statements sometimes insert spaces to make the number easier to read, but when you type an IBAN into a payment form, you leave the spaces, hyphens, and any other punctuation out.
The two check digits aren’t decorative. They’re calculated from the rest of the number using a formula called MOD-97, and payment systems re-run the same calculation when you enter the IBAN into a transfer screen. A typo almost always breaks the math, and the transfer is refused before any money moves.3IBAN.com. IBAN Checker – Validate and Check IBAN Number for Errors That’s useful when you’re checking that you’ve copied your own number correctly: paste it into your bank’s transfer form or an IBAN checker, and if it’s accepted as valid, the characters are at least internally consistent.
IBAN or SWIFT/BIC: Which Is Which
These two codes sit side by side on the statement and get mixed up constantly. The SWIFT code (also called a BIC) is your bank’s identifier. The IBAN is your account’s identifier. One tells a sender which institution to route the money to; the other tells that institution which account to credit. For an international transfer into an IBAN country, the sender typically needs both.
If you’re trying to figure out which is which on your statement, length is the quickest tell. A SWIFT/BIC is 8 or 11 characters.4U.S. Bank. U.S. Bank Routing Number An IBAN is longer, starts with a country code, and has digits in the third and fourth positions.
If Your Bank Is in the United States
American banks don’t issue IBANs, and the United States never joined the system, so you won’t find one on a U.S. bank statement no matter how carefully you look.4U.S. Bank. U.S. Bank Routing Number For domestic transfers, U.S. banks use a routing number (also called an ABA number) paired with your account number. For incoming international wires, a sender needs your bank’s SWIFT code along with your account number.
If a company in Europe asks for your IBAN and you bank in the United States, the honest answer is that you don’t have one. Give them your SWIFT code and account number instead and explain that U.S. accounts aren’t on the IBAN system. The industry’s current migration to the ISO 20022 messaging standard in 2026 updates how wire payment data is formatted, but it does not create IBANs for American accounts.5U.S. Bank.

Other Places to Find Your IBAN
If no statement is handy, open your online banking portal or mobile app and go to the account details screen for the account you want. Most banks display the IBAN there in plain text, often with a copy button next to it.
Some banks also publish an IBAN calculator on their website: you enter your domestic account number and sort code or bank code, and the tool generates the full IBAN for that account. Those tools work, but it’s worth cross-checking the result against a statement or against the number shown inside your online banking before you send it to anyone.
If none of that works, call the bank. Expect to go through identity verification before anyone reads account details to you, which usually involves multi-factor authentication of some kind.6Federal Financial Institutions Examination Council. Authentication and Access to Financial Institution Services and Systems Once you’ve got the number, save it somewhere you can find it again. Your IBAN doesn’t change, and looking it up fresh every time invites the kind of transcription slip that sends money to the wrong place.
