Mail physical letters by just asking your AI assistant.
Yes. Fax machines in the United States and Canada use the same phone network and dialing format, so a fax sent from one country reaches the other like a regular cross-border call. Dial 1 plus the area code and number, check the number before sending, and remember that time zones and business hours differ across the border.
The United States and Canada share the North American Numbering Plan, which means both countries use the same country code, 1, and the same ten-digit format: a three-digit area code plus a seven-digit number. Dialing a fax from Toronto to Chicago works exactly like dialing a fax from Chicago to Toronto. There is no special international prefix to add, and no separate fax format to learn. The only thing that changes is that your phone provider may treat the call as long distance, depending on your plan.
| Direction | What to dial |
|---|---|
| From the US to a Canadian fax number | 1, then the area code and number |
| From Canada to a US fax number | 1, then the area code and number |
| From elsewhere in the world to either country | Your international prefix, then 1, then the area code and number |
The fax itself does not change, but the context around it does. Time zones stretch from the Atlantic coast to the Pacific, so a fax sent at the start of your workday may arrive before the recipient's office opens, or after it closes. Business hours also differ: Canadian and US holidays do not line up, so a fax sent on a US holiday may sit unread in a Canadian office that is open, and the reverse is just as common. If the fax is urgent, call ahead and confirm someone will be watching for it.
Language is a smaller wrinkle. A fax to Quebec may reach a French-speaking office, and a cover sheet in French, or at least a French greeting line, is a courteous touch. Letter sizes are the same on both sides of the border, so a standard page sent from one country prints cleanly in the other, with no resizing surprises.
Cross-border faxes still carry the same risks as any fax: pages print on a shared machine, and anyone near that machine can see them. If the pages contain health, financial, or legal details, confirm the recipient's number by phone first, and ask them to confirm receipt. Rules about handling personal information differ between the two countries, and some organizations have their own policies about sending sensitive records across the border. When in doubt, ask the recipient what their office requires before you send.
Yes, within its supported range. LetterAgent supports fax numbers in the United States and Canada, so a fax between the two countries is covered. You send a fax by asking your AI assistant: you get a per-fax quote with the page count verified, approve the exact total, and pay once through Stripe. Fax is available in testing, so describe it that way and do not promise same-day delivery. Since the dialing format is identical on both sides of the border, the number you approve is the number that gets dialed, exactly as you entered it.
