I Received an Error With Message: "Confirmation registration must be Y." How to Fix it?

Reason: It means they declared a wrong LPCO reference number.

Resolution: The LPCO reference number should be “Y”. To be able to check, check the LPCO Canadian document type declared. Go to AIRS registration type website and check the format set for this type of document.
