It depends if you ever had UCI previously.Got portal email too today. But the UCI listed in the PDF is different from what I have on the IRCC website. Name and DOB are correct. Why?
The UCI number that starts with CAN is a random temporary number from the Express Entry system. It is not the same as a regular UCI. The temporary UCI number will change to a regular UCI number after the application crosses the R10 Completeness Check stage.
