Puerto Rico at a glance
The numbers and facts you need before you dial.
What is the country code for Puerto Rico?
Puerto Rico sits squarely inside the North American Numbering Plan (NANP), which means it shares +1 with the US and Canada — there's no separate +xxx code to look up. The island lives behind two 3-digit area codes, 787 and 939, and from anywhere in the US or Canada you dial it like a domestic long-distance call: 1 + area code + 7-digit number, with no 011 and no international charges.
Code +1 was assigned to Puerto Rico by the ITU under the E.164 plan. The “+” means “dial your local international exit code”; on a mobile, press and hold 0 to type it.
All four mean the same thing — they connect your call to Puerto Rico.
How to call Puerto Rico from anywhere
Inside the NANP, Puerto Rico behaves like any US state on the phone — callers in the US and Canada just dial 1 + area code + number, skipping 011 entirely.
Full example: +1 787939 XXX XXXX — drop the local leading 0 when calling from abroad.
Puerto Rico phone number format explained
It's the familiar US 10-digit shape: a 3-digit area code (787 or 939), a 3-digit exchange (NXX), and a 4-digit line number. Because 787 and 939 sit on top of the same ground, all ten digits are always required — there's no 7-digit shortcut.
固定電話
+1 (787 or 939) NXX-XXXX — 3-digit area code + 7-digit local number.
移動的
+1 (787 or 939) NXX-XXXX — identical format; the NANP doesn't flag mobiles by prefix, and carriers pull from both 787 and 939.

Puerto Rico mobile network prefixes
The prefix after +1 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.
Claro
largest mobile operator by subscribers; nationwide LTE/5G.
T-Mobile
top-rated network experience on the island.
**Liberty** (Liberty Mobile / Liberty Latin America)
full mobile and fixed coverage.
Puerto Rico time zone
Here's a twist that catches mainland callers: Puerto Rico holds Atlantic Standard Time (AST), UTC−4, all year and never moves its clocks. So the gap with the mainland shifts on its own — in winter the island runs an hour ahead of US Eastern, but once the mainland springs forward to EDT each summer, the two line up exactly.
US mainland callers barely need to think about it — business hours overlap closely all year, give or take an hour by season. From the UK or EU, your early afternoon catches San Juan's morning.

Common mistakes when calling Puerto Rico
幾乎每次失敗的國際電話都是格式問題，而不是網路問題。
Treating it as a foreign call
the single biggest mistake: from the US or Canada there's no 011 and no international rate, because Puerto Rico is right inside the NANP.
Hunting for a +xxx code
there isn't one; the island shares **+1** with the mainland.
Dropping the area code
787 or 939 is always required, so 10-digit dialing is mandatory.
Assuming 787 and 939 mark different places
they overlay the whole island, not separate regions.
Expecting the clocks to move for DST
Puerto Rico holds UTC−4 every month of the year.
Tips to reduce the cost of calling Puerto Rico
Lean on a US or NANP calling plan
most count Puerto Rico as domestic, so you may already be covered at no extra cost.
From outside the NANP, switch to VoIP or cloud calling instead of carrier international rates.
Hold a local 787/939 virtual number so island contacts reach you in-territory.
Place calls over WiFi or data to dodge roaming charges.
Why businesses get a Puerto Rico virtual number

No — Puerto Rico is a US territory inside the NANP, so you dial it just like any US number, with no 011 and no international rate.

No. The 011 exit code is only for true international calls; for Puerto Rico you simply dial 1 + area code + number.
What are Puerto Rico's area codes?expand_more
787 and 939 — both overlay the entire island rather than splitting it into regions.

It's on AST (UTC−4) with no daylight saving — an hour ahead of US Eastern in winter, but level with it once the mainland switches to EDT in summer.

From outside the NANP, dial your exit code (00), then 1, then the area code and number — there it does count as an international call.
