Unique Client Identifier (UCI)

Unique Client Identifier (UCI) also referred to as a Client Identification Number (Client ID), can be found on any official document issued by an Immigrants, Refugees and Citizenship Canada office, Case Processing Centre or a Canadian visa office outside Canada.

A Client ID consists of four numbers, a hyphen (-) and four (4) more numbers (example: 0000-0000).

A person who has never dealt with Immigration, Refugees and Citizenship Canada (IRCC) before will not have a Client Identification Number.
