What is a UCI?
UCI stands for “unique client identifier.” It is also known as a client identification number (client ID). It appears on official documents you get from Citizenship and Immigration Canada (CIC). It has four numbers, a hyphen and four more numbers. (Example: 0000-0000).
If you are applying to CIC for the first time, you will not yet have a UCI. If so, and you are filling out a form that asks for one, write “Not Applicable” or “N/A” in the space provided.
If you are applying online and the form does not allow you to input “N/A,” leave the space blank.
Please use this option only if:
- the normal processing time for your application has passed and
- you cannot verify the status of your application using the online application status tool or
- you wish to report important changes about your application, such as births, deaths, marriages, divorces, adoptions, changes in address, changes in job status or
- you need urgent processing or
- you would like to make a refugee claim
In Canada: You can use this case specific enquiry form.
Outside Canada: You can use the case-specific enquiry form for the visa office where you sent your application.
