An applicant who had submitted their PR file about two weeks earlier couldn't register for the IRCC application tracker, and the system said their details weren't recognized.
What the group confirmed:- A newly filed application is first assigned a temporary UCI starting with "CAN" — this temporary ID can't be used to create a tracker account.
- You need to wait until biometrics and the medical exam are completed. Once both are done, IRCC issues a permanent, numeric-only UCI, and that's the ID that lets you successfully register for and use the online tracker.
Practical takeaway:- Don't be alarmed if the tracker rejects your details in the first couple of weeks after filing — this is expected while your UCI is still temporary.
- Complete biometrics and your medical exam as soon as you're able to, since both are prerequisites for getting the permanent UCI.
- Once you have the numeric UCI (no more "CAN" prefix), try registering for the tracker again.
