Why is my AIB Ireland IBAN showing as invalid?

Technical Q&A

Topic summary

AIB Ireland IBAN being rejected as “invalid” when trying to enter it. The poster says they already saw a prior solution and believed an “IE” IBAN should work, but it still fails.

Key guidance provided:

  • The IBAN must belong to a banking institution physically located in the Republic of Ireland; “virtual” banks or accounts that mimic local bank details (e.g., Payoneer-style) or banks in another country may not be supported.
  • If the bank is genuinely Ireland-based and the error message isn’t specific, try updating the IBAN using Google Chrome Incognito mode.
  • If these steps don’t resolve it, the recommended next action is to contact Shopify Support via the Help Center flow.

Outcome: No confirmed fix yet; the issue remains open pending troubleshooting and/or support contact.

If the following troubleshooting steps don’t allow you to add your IBAN, then I would recommend contacting Shopify Support.

  1. Can you confirm that your IBAN is for a banking institution physically located in the Republic of Ireland (where you are located). “Virtual” banks, companies that mimic bank accounts in certain locations (like Payoneer accounts), or banks located in a different country can’t be supported.

  2. If the error doesn’t hint at what needs to be fixed, and the IBAN is from a banking institution physically located in the Republic of Ireland, then we’ll want you to try to update this using Google Chromes Incognito mode.

You can do this by logging into your store through the help center, searching your question/issue, then selecting “continue” at the bottom of the page that displays the search results.
