Who OneFaxNow Can Help With International Faxing
Many people searching for "international fax" actually need to fax TO a North American number from abroad. Here is how OneFaxNow fits.

Companies outside the U.S. that need to send contracts, invoices, or legal documents to American counterparts with U.S. fax numbers.
U.S.-Canada cross-border
Cross-border faxing between the U.S. and Canada uses the same country code (+1). OneFaxNow handles both seamlessly -- no extra fees.

People outside the U.S. who need to fax documents to USCIS, immigration attorneys, or employers with U.S. fax numbers.

Common International Fax Mistakes to Avoid
Including redundant country codes
If someone gives you a number as +1-212-555-1234, do not add 011 in front. The + already represents the international prefix.
Forgetting to drop the leading zero
Many countries use a leading zero in domestic dialing (e.g., 020 for London). Drop the zero when adding the country code: +44 20, not +44 020.
Using the wrong international prefix
From the U.S./Canada, the international dialing prefix is 011. From most of Europe, it is 00. Online fax services usually handle this for you.
Confusing fax and phone numbers
A fax number looks like a phone number but connects to a fax machine. Sending a fax to a voice line will fail. Always confirm the number is for a fax machine.
