Area code 939

Area code 939 serves Puerto Rico, including Bayamon Norte, Santurce and Carolina (Atlantic time). It has been in service since September 15, 2001 and shares its area with 787.

Numbers starting with 939 drew 44 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 50 complaints to the FCC since November 2023. The number on your screen can be faked, so a 939 number proves nothing about where a call came from.

Phone companies holding 939 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 97% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
