What is an IRCC number?
I receive a few emails every week asking about the IRCC number. I thought it would be a good idea to answer this question here instead of answering it individually.

What kind of numbers could you receive from IRCC?
IRCC usually issues the following numbers when interacting with applicants.
- The Unique Client Identifier (UCI): This number is unique to every applicant. Therefore, a family of four will receive four UCIs, and each UCI is individual to one of the family members.
- Application number: Also known as the file number, an application number is unique to each application. Consequently, this number could cover one or more applicants.
- Document number: If IRCC issues a document (e.g., a work permit) for you, they will attach a unique number to that document.
- Form number: Every IRCC form has a number that usually appears on the lower left-side corner. Most of these numbers begin with IMM. For example, IMM 5669 is the Schedule A Background/Declaration form.
What is an IRCC number, then?
When you receive a Biometrics Instruction Letter, you’ll notice a number on the lower half of the second page. This number is the IRCC number and assists you in booking a biometrics appointment. Here is an image.

Remember, the IRCC No. in this context is limited to BIL (Biometrics Instruction Letter).
