To those who have a hard time linking their application to their GCKey account, here is what the IRCC customer service told me in linking the application:
1. Make sure that the Last Name is CAPITALIZED.
2. On the part where you put the number of family members, put the NUMBER of ADULTS in the box (if spouse DIDN’t co-sign, EXCLUDE them). On my application: I have 2 kids, my wife as a co-signer, my self, and my mom and dad. This was where I messed up as I kept putting 6 as the number. It should just be “4”.
For E.G -
A. Enter the application number without the prefix ‘X’.
B. Under Applicant Details, enter the Principal Applicant’s UCI number (if available — you can find it on their visitor visa and search with passport details).
C. Set the number of applicants to ‘3’, and if you are adding your spouse as a co-signer, try setting it to ‘4’.
I finally linked my Parents application and able to see the progress.
