Why is my AIB Ireland IBAN showing as invalid?

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.
