The first thing you need to do is find out the country code for Puerto Rico, which is 1.
The next step is to find out the area code for the city you want to call in Puerto Rico. For example, if you want to call the city of San Juan, you would need to use the area code of 939.
After you have the area code, all you need to do is dial 011, then the country code, then the area code, and finally the phone number. So, it would look like this: 011-1-939-555-1212.
If you are trying to call Puerto Rico from Anguilla but you don’t know the area code, you can use the area code of 787.
