Question 4 of 4
Where to find your application number or UCI
What to look for
Application number
1 letter and 9 digits. It is in the top corner of IRCC letters, such as the acknowledgement of receipt. It is also in your IRCC account, under your applications or your messages.
UCI (client ID)
8 or 10 digits, written 0000-0000 or 00-0000-0000. It is on IRCC letters, and on documents such as a study or work permit.
Found neither?
Either number is enough. Cannot find either one? Choose No. The request can ask IRCC to search by your name, date of birth and passport details.

Do you have either one?
We never ask for your name, passport or application number here.
