Help Centre what do you need help with?

Where can I find my client ID/UCI?

This eight or ten digit number appears on all documents you get from us. It looks like this: 0000-0000 or 00-0000-0000.

If you have sent us an application before

Look for this number on:

  • letters we sent you
  • your immigration document such as a PR card, study or work permit

If you do not have any of these documents but want to fill out an application form:

  • you can leave the field for UCI (Client ID) blank

If you have not dealt with us since 1973, you will not have a UCI or a Client ID.

If you have not sent us an application before

You will not yet have a client ID. If 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 write “N/A,” leave the space blank.
