Receiving funds from overseas or setting up an international transfer requires more than just your standard six-digit sort code and eight-digit account number. If an overseas employer or relative tries to send money without an International Bank Account Number (IBAN) and Bank Identifier Code (BIC), the transaction is likely to be delayed or rejected by clearing networks.
Your Bank of Ireland UK IBAN is an extended alphanumeric code that incorporates your existing domestic account number and sort code into a standardized global format. Knowing where to look for your official IBAN and BIC—and how to verify that you are copying the correct digits—helps ensure incoming international payments reach your balance without administrative holds.
Bank of Ireland IBANs consist of 22 numbers including the following:
- 2 letter - IE, country code
- 2 check digits
- 4 characters - BOFI, the bank code
- 6-digit branch code
- 8 digits - your account number

Step-by-Step Guide to Finding Your IBAN and BIC
- Log into your mobile banking app: Open the Bank of Ireland app on your verified mobile device and sign in using your standard login passcode or biometric check.
- Select the specific account: Tap on the tile for the current account or savings account that you want to receive the international payment into.
- Open the account details menu: Select 'Details' or 'Manage Account' from the top navigation menu to view your official account identifiers.
- Locate the IBAN and BIC rows: Scroll down past your standard UK sort code and account number until you see the 22-character string labelled 'IBAN' alongside your bank's 8- or 11-character BIC (SWIFT code).
- Use the in-app copy tool: Tap the copy button adjacent to the IBAN rather than writing the numbers down by hand, which prevents accidental character transposition errors.
- Check an official bank statement as a fallback: If you do not have mobile app access, download your latest PDF statement from 365 online; your full IBAN and BIC are printed at the top-right corner of the first page.
Troubleshooting Common Access and Verification Issues
- MFA Passcode Not Arriving When Logging In
Cause: Mobile network signal drops or a temporary cellular carrier delay preventing SMS authentication codes from reaching your handset.
Simple Fix: Check your network signal, restart your mobile device to re-register with your carrier, and request a fresh verification code after 60 seconds.
Fallback Action: Call the Bank of Ireland UK digital support team to check your registered security telephone number and authenticate your account verbally. - Account Details Screen Freezing or Loading Blank
Cause: Stale temporary cache files or an outdated version of the mobile banking application installed on your device.
Simple Fix: Close the app completely, clear its cached data in your phone settings, and make sure you have installed the latest release from the App Store or Google Play Store.
Fallback Action: Log into the 365 online desktop portal via a computer web browser to view your account details and statements. - IBAN Displaying as Restricted or Account Locked
Cause: Repeated incorrect login attempts have triggered an automated security hold, or your account requires updated Know Your Customer (KYC) documentation.
Simple Fix: Check your registered email address for any administrative notifications from the bank regarding required account review documents.
Fallback Action: Phone the customer service team with your debit card and sort code to pass security checks and request a manual account review.
Pro-Tip: Check the first two letters of your IBAN before sharing it with an international sender. A Bank of Ireland UK current account will always feature a British IBAN beginning with the country code 'GB', whereas an account held with Bank of Ireland in the Republic of Ireland starts with 'IE'—and mixing these prefixes up will cause international clearing systems to reject the transfer.
Frequently Asked Questions
Why is my Bank of Ireland IBAN 22 characters long?
UK banking systems follow the European Committee for Banking Standards structure, which sets a fixed 22-character length for all British IBANs. In practice, the code begins with the 'GB' country code and two automated security check digits, followed by a four-letter bank identifier, your standard six-digit UK sort code, and your eight-digit account number. What this means is that your IBAN is simply your existing domestic account data wrapped in an international routing format. An important limitation is that missing out any single character—even a leading zero in your account number—will cause automated payment verification checks to fail. To prevent transfer delays, always use your digital banking app to copy the entire string rather than attempting to construct the IBAN manually from your sort code.
Do I always need to provide a BIC alongside my IBAN for overseas payments?
When someone sends money from an overseas bank account, their financial institution uses the Bank Identifier Code (BIC)—often called a SWIFT code—to identify the specific bank network receiving the funds. While SEPA (Single Euro Payments Area) transfers between European banks often process using only an IBAN, cross-border payments originating from outside Europe typically require both the IBAN and the correct BIC to clear successfully. If a sender inputs your IBAN but leaves the BIC field blank on an international wire transfer, intermediary correspondent banks may hold the funds in a review queue or return them to the sender less an administrative fee. Provide both your official IBAN and BIC to your sender, and ask them to check that their bank's payment form accepts standard 8-character SWIFT codes.
Why was an incoming international payment rejected even though my IBAN was correct?
An incoming cross-border payment can fail even when the IBAN string is accurate if the sender's bank encounters a name mismatch or if the transfer triggers automated compliance filters. International clearing networks check that the beneficiary name on the transfer instruction closely matches the official legal name registered on your bank account. Furthermore, certain overseas banks apply strict limits on cross-border payments without supporting invoice documentation. If a transfer fails to arrive within four working days, ask the sender to obtain an official SWIFT MT103 transaction tracking copy from their bank, then contact the Bank of Ireland UK international payments desk to check whether incoming funds are being held for compliance verification.
