How to Fax the US From Puerto Rico

The way to send a fax from Puerto Rico to the United States with a machine is fairly straightforward, although sending a fax via email is much easier. Because both the US and Puerto Rico are in the North American Numbering Plan, you don't need to dial 011 for an international line. Just dial ( 1 ) followed by the area code in the United States and then the number you are trying to fax.

Format your dialing to look like this:

1 - [area code] - [fax number in the United States]

The international dialing prefix for Puerto Rico is 011, default for the North American Numbering Plan. Note: not all the countries and territories part of the NANP are in North America! Just dial '011' to get an international line.

Dialing Codes and Things to Know

The United States is part of the North American Numbering Plan (members share '1' as the country code).

Is Your Machine Dialing Too Quickly?

Sometimes delayed connections in the phone switches require you to insert a pause after the international dialing prefix ( 011 ), the country code ( 1 ), and the number that you are dialing.

Some machines interpret a comma ( , ) as a pause, while other models use the pound sign ( # ).

Speed Settings

Noise on the long-distance call between Puerto Rico and the US may cause data loss during transmission. If this happens, try lowering the baud rate on your fax machine to 9600 baud.

Note: Lowering the baud rate will allow a more stable connection, however, it will slow down transmission. Long-distance calling charges may be more.
