Where can I find my client ID/UCI?

This eight digit number appears on all documents you get from Citizenship and Immigration Canada (CIC). It looks like this: 0000-0000.

If you applied to CIC before

Look for this number on:

  • letters you received from CIC,
  • 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.

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

If you are applying to CIC for the first time

You will not yet have a client ID. 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.
