939 area code summary
Area code 939 is an overlay for Puerto Rico, sharing coverage with the longstanding 787 area code. Introduced in 2001 due to growing demand for mobile and landline numbers, 939 is now widely used across the island. It encompasses San Juan, Ponce, Mayagüez, and other municipalities, serving both residential users and businesses. Puerto Rico’s economy is centered on manufacturing (especially pharmaceuticals and electronics), tourism, and services. The 939 area code helps maintain continuity in telecommunications as more residents adopt mobile-first communication. It also supports growing sectors like remote work and digital services. Despite its U.S. territory status, having a 939 number signals Puerto Rican identity and connection to the island’s distinct culture and business landscape.
