PR card number obviously will not yield any results.So
yrs I did try with PR card number, UCI and with application number but there is nothing about my file. But when I called them today they gave me the application number
If your application is in the system, then entering your UCI in the correct format should bring it up. If it is a 8 digit UCI, then the format is XXXX-XXXX (include the hyphen).
Sometimes, the format might look like this : XX–XXXX–XXXX => If your UCI has more than 8 digits, use this format (include the hyphens)
