What Is the 787 Area Code?

The 787 area code is a North American Numbering Plan (NANP) telephone prefix assigned to Puerto Rico, an unincorporated US territory in the Caribbean. It covers the whole island — every municipality from the capital of San Juan to coastal towns and mountain communities inland.
The 787 code was created in 1996 when Puerto Rico received its own dedicated prefix. Because Puerto Rico is part of the NANP, calling the island from the mainland works just like a domestic call, with no international dialing required.
For callers, businesses, and anyone searching for a regional number, the 787 signals an immediate connection to Puerto Rico's vibrant culture and its growing Caribbean economy.
Coverage Area and Geography
The 787 area code covers all 78 municipalities of Puerto Rico. This includes the densely populated San Juan metro area, the southern city of Ponce, the western hub of Mayagüez, and every island community in between.
The territory sits about 1,000 miles southeast of Miami, in the northeastern Caribbean. It also covers the smaller islands of Vieques and Culebra, which fall under the same numbering plan as the main island of Puerto Rico.
For businesses using virtual numbers to reach the Puerto Rico market, a 787 prefix signals immediate local relevance to customers, suppliers, and business partners across the island.
Major Cities in the 787 Region
Several cities define the identity of this island territory:
- San Juan — the capital and largest city, a major cruise port and cultural center
- Bayamón — a large city in the San Juan metropolitan area
- Carolina — home to the island's main international airport
- Ponce — the largest city on the southern coast, known for its historic architecture
- Caguas — a central mountain-valley city south of San Juan
- Mayagüez — the leading city on the west coast
- Arecibo — a north-coast city famous for its former radio telescope
Together these cities make Puerto Rico one of the most vibrant and culturally rich regions in the NANP, blending Spanish heritage with a modern Caribbean economy.

Time Zone for the 787 Region

Every community in the 787 area code region observes Atlantic Standard Time (AST) at UTC−4. Unlike most of the mainland United States, Puerto Rico does not use Daylight Saving Time, so the island stays on the same offset all year.
For teams scheduling calls with 787 contacts, here are the key time conversions:
- Winter: 9:00 AM AST = 8:00 AM EST (US East Coast)
- Summer: 9:00 AM AST = 9:00 AM EDT (same as East Coast)
- 9:00 AM AST = 1:00 PM GMT (UK standard time)
- 9:00 AM AST = 6:00 AM PST (US West Coast winter)
Because Puerto Rico skips Daylight Saving Time, its gap with the mainland changes twice a year. In winter the island runs one hour ahead of Eastern Time; in summer the two match. Keep this shift in mind when scheduling calls across the 787 region.
History of the 787 Code
The 1996 Split from 809
The 787 area code was established on March 1, 1996. Before that, Puerto Rico shared the 809 code with much of the Caribbean, including the Dominican Republic and the Bahamas. As demand for numbers grew, the region was divided so each territory could have its own dedicated prefix.
That split gave Puerto Rico a distinct telephone identity for the first time. The 787 quickly became a recognizable symbol of the island, appearing on everything from business cards to radio ads across the territory.
The 939 Overlay
In 2001, the 939 overlay was added on top of the 787 to expand the supply of available numbers. The overlay covers the same territory, so 10-digit dialing became mandatory. This mirrors the overlay approach later used by the 786 area code in Miami, where a second prefix was layered over an existing one.
How to Dial a 787 Phone Number
Dialing a 787 phone number follows the standard 10-digit format required across the United States. Because the 939 overlay shares the territory, 10-digit dialing has long been mandatory in Puerto Rico. According to FCC dialing rules, every domestic call must include the full area code plus the 7-digit local number.
- From within the US: Dial 1 + 787 + 7-digit local number
- From Canada: Dial 1 + 787 + 7-digit number
- From outside North America: Dial your exit code + 1 + 787 + 7-digit number
Most smartphones auto-format calls correctly when a contact is saved with the full number. Calls between the mainland US and Puerto Rico are treated as domestic, so no international rates apply to the 787 region.
