Work Permit Canada Document Number | Locate, Format & Use

What Is the Work Permit Canada Document Number?

The work permit Canada document number acts as the unique ID for your specific permit. IRCC prints it on the issued paper or PDF you carry. It helps officers and systems identify that exact document.

Unlike approval letters, which have tracking numbers, this code appears only on the final permit. Employers check it. Border agents scan it. It’s tied to your work status, not your whole IRCC history.

IRCC has used this system for years on temporary docs like work and study permits. Each new permit gets a fresh number. Your old one won’t work for updates.

Format and Location on the Document

Expect 10 characters: one letter (usually “U” for work permits) plus nine digits. Example: U123456789. It may sit top right or center, without a “document number” label. Just spot the bold code near the top.

Pull out your permit. Hold it landscape. Look above the photo or expiry. That’s it. No need to guess.

Work Permit Canada Document Number vs. UCI and Application Number

Forums buzz with mix-ups. People paste their UCI into permit fields. Delays follow. The document number IDs your permit alone. UCI tracks you across all IRCC files. Application number follows your request from start to finish.

Use the wrong one on IMM 5710? Expect questions or returns. Know them cold for smooth sailing.
