Geographic Coverage
Area code 787 covers the entire island of Puerto Rico, a U.S. territory in the northeastern Caribbean. Major population centers include San Juan (the capital), Bayamon, Carolina, Ponce, Caguas, and Guaynabo in the greater metro region. Smaller cities such as Arecibo, Mayaguez, Aguadilla, Humacao, and Fajardo are also served. Because Puerto Rico is a single unified territory without county subdivisions equivalent to U.S. states, the code blankets all 78 municipios (municipalities) island-wide.
Population and Business Context
Puerto Rico's population of roughly 3.2 million makes the 787/939 market comparable in size to a mid-large U.S. state. Key industries include pharmaceuticals and biotechnology, tourism and hospitality, financial services, and retail. San Juan serves as the commercial hub, housing major corporate offices, hospitals, and government agencies. Small and medium-sized businesses are prevalent across the island, and the healthcare and education sectors are significant employers in municipalities outside the capital.
Area Code History
Area code 787 was created in 1996 when Puerto Rico split from the 809 area code, which had historically served much of the Caribbean. Puerto Rico and the U.S. Virgin Islands were among the first regions to receive their own dedicated codes as demand for telephone numbers grew rapidly in the 1990s. In 2001, the North American Numbering Plan Administration introduced overlay code 939 for Puerto Rico to address number exhaustion while keeping the same geographic footprint as 787.
How to Dial
All calls within Puerto Rico using area codes 787 and 939 require 10-digit dialing, meaning you must dial the area code plus the 7-digit local number even for calls within the same city. Callers from the U.S. mainland dial 1 + 787 (or 939) + the 7-digit number. Puerto Rico uses the North American Numbering Plan (NANP), so standard U.S. calling rates generally apply, though some carriers may treat calls to Puerto Rico differently. Always confirm with your carrier regarding applicable rates.
