How to Fax to Canada from the U.S. (2026): Number Format, Costs, and Tips

Faxing from the U.S. to Canada is usually simple, but it still helps to use a consistent number format and send a clean PDF—especially if the fax is time-sensitive.

Correct Number Format

Use international format with a plus sign:

Example: +1 416 555 0123
Country code for Canada is +1 (same as U.S.)
Include the area code (e.g., 416 for Toronto)
