- Source: Telephone numbers in Puerto Rico
Telephone numbers in Puerto Rico are assigned under the North American Numbering Plan (NANP). Their area codes are 787 and 939.
Prior to March 1, 1996, Puerto Rico was one of many Caribbean islands served by area code 809. On that date Puerto Rico was assigned the new area code 787. Permissive dialing of 809 ended January 31, 1997.
Within only four years, 787 was already on the brink of exhaustion due to the proliferation of cell phones and dial-up Internet connections. To solve the problem, 787 was overlaid with area code 939 in or about September 2001, with ten-digit dialing required for all calls.
