Dialing Examples
Puerto Rico Area Codes
Puerto Rico uses two area codes that cover the entire island. Unlike the US mainland where area codes correspond to geographic regions, both 787 and 939 serve all of Puerto Rico as overlays. The 939 code was introduced in 2001 when 787 began running out of available numbers.
| Area Code | Coverage | Introduced | Notes |
|---|---|---|---|
| 787 | All of Puerto Rico | 1996 | Original area code, replaced 809 for PR |
| 939 | All of Puerto Rico | 2001 | Overlay code for new number assignments |
Important: Prior to 1996, Puerto Rico shared the 809 area code with the Dominican Republic and other Caribbean territories. If you have an old contact number starting with 809 for Puerto Rico, it has since changed to 787 or 939.
Major Cities and Municipalities
Since both area codes cover the entire island, there is no way to determine a caller's location from their area code. Here are the major population centers in Puerto Rico, all reachable via either 787 or 939.

Most US plans include Puerto Rico as domestic calling. Check with your carrier.
Best Times to Call Puerto Rico
Puerto Rico uses Atlantic Standard Time (AST), UTC-4 year-round. Puerto Rico does not observe daylight saving time, which means the offset from mainland US cities changes depending on the season.
| Your Location | Winter Offset | Summer Offset | Best Calling Window |
|---|---|---|---|
| US East Coast (EST/EDT) | PR is +1 hour | Same time | 9 AM - 9 PM your time |
| US West Coast (PST/PDT) | PR is +4 hours | PR is +3 hours | 6 AM - 6 PM your time |
| UK (GMT/BST) | PR is -4 hours | PR is -5 hours | 1 PM - 10 PM your time |
| US Central (CST/CDT) | PR is +2 hours | PR is +1 hour | 8 AM - 8 PM your time |
Tip: In winter (November-March), Puerto Rico is 1 hour ahead of the US East Coast. In summer, they are on the same time since PR does not change clocks. Business hours are typically 8 AM - 5 PM AST.
Troubleshooting Common Issues
Puerto Rico does NOT have its own country code
A common misconception is that Puerto Rico has a separate country code. Puerto Rico uses the US country code +1 with area codes 787 and 939. If you are searching for "Puerto Rico country code," the answer is simply +1. You do not need to dial a different country code than you would for any other US number.
Being charged international rates for Puerto Rico calls
Since Puerto Rico is a US territory, most major US carriers treat calls to PR as domestic. However, some smaller carriers or legacy plans may still charge international rates. Check your plan details. If you are being charged international rates, switching to a VoIP service like BubblyPhone can save you money since Puerto Rico calls are billed at US domestic rates.
Time zone confusion due to no daylight saving
Puerto Rico stays on AST (UTC-4) all year. This means that in winter, Puerto Rico is 1 hour ahead of New York, but in summer they are the same time. If you are scheduling a call, always confirm whether you need to account for the 1-hour difference (winter) or not (summer).
10-digit dialing required
Puerto Rico requires 10-digit dialing for all calls, even local ones. You must always include the area code (787 or 939) when dialing any number on the island. Simply dialing 7 digits will not connect your call.
Network issues after storms
Puerto Rico is in the Caribbean hurricane belt, and major storms can damage telecommunications infrastructure. After Hurricane Maria in 2017, the telecom network took months to fully restore. During hurricane season (June-November), be aware that service interruptions are possible. If calls are not going through after a storm, try again later or use internet-based communication if available.
