Calling Puerto Rico from United States
Dial 011 (the United States exit code), then 1 (Puerto Rico’s country code), then the local number exactly as written. So +1 (787) 555-0144 is dialled as 011 1 (787) 555-0144. From a mobile you can dial +1 directly instead of 011.
The dialing sequence
- Exit code from United States
- 011

- +1
- Trunk prefix to remove

- Dial the local number exactly as written.
- Full sequence

- Time in Puerto Rico
- AST (UTC−4, no DST)
- United States is on ET (UTC−5/−4).
Puerto Rico and United States share +1
Both countries sit inside the same numbering plan, so the call is dialled like a domestic long-distance call, but it is still an international call and is billed as one. Check your rate before a long conversation.
Step by step
Dialing Puerto Rico from United States
Four steps, and the third one is where almost every failed call goes wrong.
- 1
Dial 011: the exit code for United States
011 tells the United States network that the call is leaving the country. On a mobile you can press and hold 0 to type a + instead, which works from any country and any SIM; it is the more reliable option when you travel. - 2
Dial 1: the country code for Puerto Rico
1 is Puerto Rico's country calling code. It never changes and is the same no matter where you are calling from. - 3
Dial the local number exactly as written
Puerto Rico has no national trunk prefix, so there is nothing to remove. The number you would dial locally is the number you dial after 1. - 4
Check the local time before you dial
Puerto Rico is on AST (UTC−4, no DST) and United States is on ET (UTC−5/−4). Work out the overlap before calling; the most common cause of an unanswered international business call is simply the hour.

What is the time difference between United States and Puerto Rico?
United States is on ET (UTC−5/−4) and Puerto Rico is on AST (UTC−4, no DST). Because several of these zones observe daylight saving on different dates, check the current offset rather than assuming a fixed gap.
