Puerto Rico is a vibrant Caribbean island and U.S. territory, known for its rich Spanish colonial history, beaches, and mountainous interior. San Juan, the capital, is a major cultural and economic hub in the region.

Initially served by area code 809, Puerto Rico was reassigned area code 787 in 1996 and later overlaid with area code 939 in 2001 due to rapid mobile growth. These Puerto Rico area codes allow seamless communication with the mainland U.S., supporting business, tourism, and residents across the island.
