Area code 939 is an overlay of 787 serving all of Puerto Rico, including San Juan, Bayamón, and Ponce. Because it overlays 787, 10-digit dialing is required across the territory. Both codes cover the same geography under the North American Numbering Plan.
Across Puerto Rico, the 939 area code serves roughly 3.2 million residents in 4 communities — including San Juan, Bayamón, Carolina, among others. Numbers in the 939 zone keep America/Puerto_Ricotime, so a local line rings during your customers' business hours and shows a familiar PR caller ID on every outbound call.
939 was first introduced in 2001 as an overlay of the 787 area code, adding fresh numbering capacity to the same region without forcing anyone to change an existing number. Because an overlay shares geography with another code, ten-digit dialing is standard throughout the area. It remains an active overlay code today.
